WAN load balancing question

Hello All,
I need some help on below.
- ISP-1 provided two routers (R1 and R2), each router connect to a different internet circuit (ISP-1 and ISP-2 circuits)
- Locally have a customer router (R3)
- Locally have a public DMZ (203.xxx.xxx.xxx/24)
Requirement:-
1. Incoming/Outgoing traffics to/from DMZ should via both circuits equally (Load Balance)
2. R3 need to know where to route to internet
3. When there is outage on either internet circuit, no outage should occur. All traffics will route on the working circuit
Attach diagram what i think it will work base on the requirement. But i am not sure how the actual router configuraiton should look likes.
If it will not work base on the diagram, please help advice how can it be done.
Appreciate your time.
Regards,
Christopher

SO Load Balancing Question

Hi all,
I have a service object (SO1) which has been set to Load Balancing.
This service object has an attribute which serves as a number allocator
(NA1).
This NA1 provides a unique number across the whole application for each of
the record that require to store into DB.
The problem is, will the NA1 get replicated if the SO1 is replicated?
If yes, will NA1 crash?

Hi Serge,
Could you prefix it with the PID of the load balanced process ?No I can't. At least not at the moment.
When a service object is replicated, it is automatically replicated into adifferent partition...
Thanks.
An advice, make the NA1 shared. So if you get to do multithreaded accessto
it, you won't screw up things.I am thinking it may be better off to create it as a service object on it's
own.
How is the number returned by the NA1 generated ?It gets generated by Forte's code.
... Try to make it so that the
load balanced partitions don't need to access the database more than onein
5 min. to get a new Seed Key. This would not need to PID.Thanks for your advise.
Regards
Martin Chan

Your right, they can generate the same number. How much control do you have
over the ID being generated? Could you prefix it with the PID of the load
balanced process ?
Just a note: When a service object is replicated, it is automatically
replicated into a different partition, possibly on the same machine or on a
different one.
An advice, make the NA1 shared. So if you get to do multithreaded access to
it, you won't screw up things.
How is the number returned by the NA1 generated ? If NA1 is using a stored
procedure, or something like:
Start TRX
read number
newnumber = number+5000
write back newnumber
End Trx
Something like will be very safe. The Database Index Table is taking care
of the critical section. Then you can be sure that each replicate can be
independent (not hit into each other) for 5000 iterations. Depending on the
frequency, you may want to up this number or lower this number. Too high it
would make the key very high very soon with wholes in the sequence. Too low
and you would have hit between the replicates. Try to make it so that the
load balanced partitions don't need to access the database more than one in
5 min. to get a new Seed Key. This would not need to PID.

Hi Serge,
The number return by the NA1 is used as a primary key for each of therecord
that stores in the DB.
The Number Allocator NA1 is required to access to DB to update an ID table
which carry the next available sequence number. NA1 will only update this
table for every 5000 records.
For example, the initial value of the sequence is: 1
The next update will change the value to 5001, next will be 10001 and soon.
>
The properties of this NA1 class at runtime
Shared - Disallowed
Distributed - Disallowed
Transactional - Is Default
Monitored - Disallowed
Unfortunately, this attribute is not a handle but is instantiated by theSO1
itself.
I have been thinking, if SO1 is replicated within the same partition, and
each replicate will carry its own NA1. NA1 and the replicate of NA1 may
return a same number if their initial values of the sequence are the same.
Correct?

Let's see if I understand right.
You have a service object that keep a handle to an object that either keep
state information, or that generate state information. Now the thing to
figure out is which is it. Let's assume that NA1 is a number generator,
that does not need to be synchronized or that doesn't need to access any
external resource. It would still work, depending on the algorythm you are
using.
Will they share the same NA1? It depends on the nature of NA1, but for sure
NA1 would have to be an anchored object. An if multiple partitions would
share the same object "only" for key generation, you would bring down your
performance on key generation or key update (by adding one inter-process
call).
In short:
1. Many scenarios can happen, you need to be clearer on your description.
2. If you are sharing an object by load balanced partitions, this greatly
reduce the gain of load balancing the partition.
3. If NA1 is keeping state, any access to it would need to be controlled
"shared".
Have fun now...

WAN load balancing

Hello
I have the following issue with a Cisco 2811 router. I have two WAN connection ( fiber and ADSL ) and I want to make WAN load balancing
so I add two route : 0.0.0.0 0.0.0.0 dialer1 and 0.0.0.0 0.0.0.0 fa1 the problem is with fiber connection (fa1) in this configuration I can't ping WAN
from outside or use NAT on this connection. If I change default route's like this it's working but is not WAN load balancing : 0.0.0.0 0.0.0.0 dialer 150
0.0.0.0 0.0.0.0 fa1. Any idea.

Hi Richard
I come back with more details:
First I try to setup router with WAN failover like this:
route-map SDM_RMAP_1 permit 1
match ip address 101
match interface FastEthernet0/0
route-map SDM_RMAP_2 permit 1

And I want to achive the following results:
All computers from LAN use for internet connection y.y.y.y and if this failed use x.x.x.x and when come back y.y.y.y use this connection.
And I have one server with few services ( DNS, WWW, MAIL...) which must use just x.x.x.x connection if this failed dosen't matter if this services not working.
But with this configuration one thing not working i can't access from outside Mail server , DNS, WWW with x.x.x.x connection ( IP ) if I change default route like :
ip route 0.0.0.0 0.0.0.0 x.x.x.x track 1
ip route 0.0.0.0 0.0.0.0 y.y.y.y 150
it's working

WAN Load-Balancing and multi VLAN design

Hello,
I need some help to define the design of a specifi LAN-WAN network.
1) There are 2 independant WAN entries (they have their own ISP-managed router)
2) I need to load-balanced the requests over the 2 WAN
3) If possible, the load-balancer must be redundant (GLBP ?)
4) On the LAN itself, there must be 15 different VLAN
5) We also need a DHCP solution (also redundant if possible) to provide IP to these VLAN, with unique gateway (the load-balancer)
What do I need to implement this configuration ?
And is it possible to configure with as much GUI as possible ?
Thanks in advance for your help.

Dear Mike,
Thank you and welcome to the Small Business Support Community.
It is possible to configure load balancing with NAT, however in this case, remote internet servers will potentially see sessions from remote hosts behind the SRP541W coming from different source IP addresses (the WAN IP addresses), causing the sessions to be reset unexpectedly.
The Policy Routing setting you setup is exactly what I would do in your case.
I hope these answer your question and please do not hesitate to reach me back if there is anything else I may assist you with.
Kind regards,

SRP541W WAN Load Balancing and NAT

Hello All,
New to the forums. Thanks for taking the time to read my post. I recently switched my office over from a RV042 to SRP541W. We have 2 DSL lines and have used the Load Balance feature on the RV42 to make the best of the connecton speeds. When setting up the SRP541W when i select load balancing it tells me NAT should be disabled. Why is that? I see a place to input static routes but Im not entirly sure what needs to be done here to set this up correctly. Any input would be appriciated. Also right off the bat we had some issues with access to Google Docs and Mail. I think its becuase those sites dont like seeing access from multiple IPs (fromt the Dual WAN) so I set up a entry in Policy Routing directing all traffic from port 443 to go through one WAN, is this the right way to do this?
Thanks!
Mike-

Load Balancing question

My company is in the process of building a small scale network architecture strictly for testing purposes. We have a DMZ area that contains 2 load balancers and 1 web server. The web server is a SunFire 280 and has two gig e nics. They want to cable one nic to one load balancer and one nic to the other. Since this is only one box we have to put the nics on separate subnets. The question is, can I configure the load balancers in a failover situation of an active active situation with one load balancer on one vlan and another load balancer on a separate vlan.

I did not able to understand why you want to give ip to two NICs from different subnets.
There is NO any requirement, like that. If you have your own requirement can you explain me that?

CSS load balancing questions

I hope that someone can help with 2 simple (i think) CSS questions.
1. When configured properly for load balancing, should the CSS round-robin between servers or will it continue to use only one server until triggered by some event or parameter?
2. If 1 of 2 load balanced servers fails, how does load balancing proceed? Will it continue to try to load balance between the servers or will it give up on the failed server unitil some event or timeout occurs?
Thanks in advance,
Eliot

Hi Eliot,
The CSS can be configured to perform load balancing in a variety of different ways. Least connections, round robin, ACA etc. Each new connection through the CSS will be round robined over each of the servers in your server group.
If a server fails then the CSS will know it has failed through the use of keepalives (based on TCP connection, ICMP etc) and no longer send requests through to that server. Traffic associated with a previous connection to the failed server will be sent to on of the surviving servers. It is then up to the behavior of the application as to if the user experiences any disruption.
Hope this helps
Brett

Clustering problems and load balancing question

          I am using Weblogic 6.1. My Windows NT environment consists of 10 web client-simulator
          machines, 2 App. Server machines and one database server machine. I have defined
          one cluster on each app. server. Each cluster is running 3 Weblogic instances, or
          so it should be when I fix my problems!
          My questions/problems are the following:
          1. Can I use a software dispatcher to perform workload balancing between the 2 weblogic
          clusters? That is, the client-simulator machines send the requests to the software
          dispatcher which performs workload balancing between the 2 Weblogic clusters. The
          clusters perform round-robin amongst all instances. Note that the documentation only
          talks about Hardware Balancing.
          2. I am having problems with my multicast IP addresses. For instance, on one App.
          Server machine, I am using the multicast IP address: 239.0.0.1 for MyCluster. When
          I start the Admin Server, I get a JDBC error: "... multicast socket error: Request
          Time Out". I have used the utils.MulticastTest utility which shows the packets not
          being received:
          I (S1) sent message num 1
          I (S1) sent message num 2
          I (S1) sent message num 3
          I (S1) sent message num 4
          What am I doing wrong?
          3. Re. the cluster configuration:
          NOTE: I have executed my workload using 2 independent App. Server machines with a
          software dispatcher - no clustering. Each App. Server used a jdbc connection pool
          of 84 database connections. The db connections happened to become my bottleneck.
          When I tried to increase the number of connections in the jdbc pool, throughput decreased
          dramatically. Thus, I decided to add a cluster of Weblogic instances to each one
          of my 8 x 900Mhz machines in order to scale up. Unfortunatly, adding clusters have
          not been that simple a task - probably because I am totally new to the Web Application
          Server world!
          Here is what I've got so far:
          I have obtained 3 static IP addresses for the 3 instances of Weblogic instances that
          I wish to run within the cluster. All servers in the cluster use port number 80.
          There is a corresponding DNS entry for each IP address. My base assumption is that
          one of these instances will double up as the Administration Server... Is it true,
          or do I need to define a separate Admin server if I wish to run 3 Weblogic instances
          (each with a connection pool of 84 database connections for a total of 252 database
          connections)?
          Do I need to re-deploy my applications for the cluster? And if so, would this explain
          why I am having problem starting my Admin Server?
          I think this is it for now. Any help will be greatly appreciated!
          Thanks in advance,
          Guylaine.

          We also support software load balancers (for e.g. resonate)
          The software dispatcher should be intelligent enough to decode the
          cookie and route the request to the appropriate servers. This is
          necessary to maintain sticky load balancing.

          You should run the above utility from multiple windows and see if each

          BEA recommends to use Admin server for administrative tasks only
          like configuring new deployments, jdbc conn pools, adding users etc..
          It's not a good idea to have admin server part of cluster.

Office Web App Load balancing Question

I am going to install office web app in load balanced farm behing f5. There are few questions i want to ask:
Do i first put servers in load balancer and start installing office web app or after installation of office web app in one server put that in load balancer and add another one or put both in load balancer and start installing.
While i tried without putting servers in load balancer with offload ssl parameter , when i tried to join second server in the farm it gave me error destination unreachable. Is it because with offload ssl parameter it is looking for load balancer or something
else? I checked port 809 from the servers and also verified the user was local admin in both machines.
Any insight will be helpful.

Hypothetical RAC load balancing question

Im trying to get a better understanding of RAC. Suppose I have the following tnsnames entry on Client1:
DEV =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dev010.net)(PORT = 1795))
(ADDRESS = (PROTOCOL = TCP)(HOST = dev020.net)(PORT = 1795))
(LOAD_BALANCE = yes)
(FAILOVER = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dev1)
(failover_mode=(type=select)(method=basic))
dev010.net and dev020.net are two nodes that I am trying to balance the connection from Client1 to.
dev010.net and dev020.net have the following listener.ora configurations respectively:
LISTENER_DEV1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dev010.net)(PORT
= 1795))
SID_LIST_LISTENER_DEV1 =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/ora92)
(PROGRAM = extproc)
(SID_DESC =
(ORACLE_HOME = /oracle/ora92)
(SID_NAME = dev1)
LISTENER_DEV2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dev020.net)(PORT
= 1795))
SID_LIST_LISTENER_DEV2 =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/ora92)
(PROGRAM = extproc)
(SID_DESC =
(ORACLE_HOME = /oracle/ora92)
(SID_NAME = dev2)
Question: since 'lsnrctl services' shows LISTENER_DEV1 and LISTENER_DEV2 are registered with services dev1 and dev2 respectively, how do I load balance Client1's connection between the two nodes if its service name is set to dev1?
Can you set up RAC with some sort of master listener?
Im new to RAC, so any help would be appreciated.

Try this:
LISTENER =
(ADDRESS_LIST =
        (ADDRESS =
          (PROTOCOL = IPC)
          (KEY = DB1.WORLD)
        (ADDRESS=
          (PROTOCOL = IPC)
          (KEY = DB1)
        (ADDRESS =
          (COMMUNITY = MYRAC.WORLD)
          (PROTOCOL = TCP)
          (HOST = )
          (PORT = 1521)
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = DB101)
      (ORACLE_HOME = /oracle/Ora92)
    (SID_DESC =
      (SID_NAME = DB102)
      (ORACLE_HOME = /oracle/Ora92)

Exchange 2013 Load Balancing Question

Hey Everyone,
I have recently started building up my companies Exchange 2013 environment and ran into some questions that I can't seem to find clear answers for on Google.
First, a little bit about my set up:
2 CAS Servers
2 Mailbox Servers
Citrix NetScaler load balancing the external URL (Controlling all incoming ports 25, 80, 443, 587, 993, and 995) to both of my CAS servers
This is not doing SSL offloading, it's just forwarding encrypted traffic to the CAS servers
I have configured a DAG between the 2 mailbox servers and am able to actively move the database my user account is on between the 2 copies with outlook disconnecting / reconnecting in about 10 - 15 seconds of moving it.
My questions started when I saw what Outlook was filling in for the "Server" field once autodiscover set it up. I found this very strange server name in it: *** Email address is removed for privacy ***
Once I read up on it, I think i understand what it does. If i understand correctly, this weird URL is sort of like an old CAS array from Exchange 2010. When I started testing the failover is when I started running into issues.
When I shut down one of my mailbox servers, my outlook will lose connection and it won't come back. The mailbox database that my user account is on successfully failed over to the other DAG copy but outlook never correctly connects. I
believe this issue has something to do with the new CAS functions of Exchange 2013 since DAG works fine.
If I look at my "Connection Status" in Outlook, I see that there are several connections open. All of them have a Proxy server address of "exchange.domain.com" and out of the 3 that show up there, they are all pointed to
the weird URL mentioned above.
Whew, long post but let me summarize my questions below:
1) If exchange is configured to be fully redundant, why does my outlook disconnect when I shut down one of the servers?
2) What is the weird URL pointing to that I mentioned above that is showing in outlook?
3) How can I get outlook to correctly not lose it's connection when any 1 of the servers goes down?
Thanks,
Zac

Hi,
According to your description, it seems that the load balancer did not configure successfully.
I recommend you refer to the following article to configure the load balancer for Exchange 2013 :

Hope this helps!
Thanks.

Connection Load Balancing question

Hi All,
this is from oracle net8 Administrator's Guide (between double quotes):
"Connection load balancing improves connection performance by balancing the number of active connections among multiple dispatchers. In an Oracle Parallel Server environment, connection load balancing also has the capability to balance the number of active connections among multiple instances. "
My question is, from that statement above, does it mean that the connection load balancing can only be useful on a OPS with MTS instances?
and second is , does it make sense (or can it be done) to implement it on single instance of MTS?
TIA,
Andi

Hi Andi,
CLB is only used in cluster configuration! In single node instance there is no advantage for ovbious reason of putting one more layer.
you are right...use only with OPS and preferably with MTS.
Best,
G

RV042 - Load Balancing question

Hi, I have the RV042 (firmware 1.3.13.02-tm) in Load Balancing mode. When I do a speedtest, the result is the total bandwidth available on my 2 connections, i.e. 8-9,000 Kbit/Sec (each line is approx 4,500 Kbit/Sec). When I stream from Netflix, the bandwidth throughput is about 4-4,5000 Kbit/Sec. Should not the RV042 stream Netflix as the combined speed between WAN 1 and 2, i.e. at 8-9,000?

Load balance permits more available bandwidth. It may effective double the speed because the requests have more pipe available to utilize but not because it increases the over all speed of your connection. If your connections are 5 mbit they remain 5 mbit.

SA520W load balancing question

I've recently setup a SA520W and am trying to configure it for load balancing. I have DSL (soon to be switched over to T1) and a wireless provider (Clearwire) as ISP's. I have only assigned a few protocols to use the secondary (wireless) connection but when the users are on the web their access is noticeably slower when load balancing is enabled. If I only have a few protocols using the optional WAN port, why would performance be affected? I understand the wireless connection is probably slower but I'm just not sure I understand why it would even enter into the equation when users are on the web. I have switched settings back to failover only, using the primary WAN port and performance improved immediately.
Is there anything I'm missing as far as configuring the load balancing? The options there seem limited but maybe I'm just not seeing everything.

Hi Arphilyaw,
If possible, can you provide us the dbglogs when the issue occurs - load balancing with protocol binding.
To get the dbglog from SA520W, login through web UI and in the URL type
https://IP_address_of_SA520W/scgi-bin/dbglog.cgi (where IP_address_of_SA520W – is the IP address of the SA520W router).
These logs will store password, so please remove any password sensitive information. Also if you are not comfortable posting the dbglog on the community, you can send it directly to me through IM or email.
Thanks,
Nitin Manglik

Cisco RV042 - Dual Wan Load Balancing - Secure Site (HTTPS) Trouble

PID VID :
RV042 V03
Firmware Version :
v4.0.0.07-tm (Aug 19 2010 19:19:50)
Ever since I setup my RV042 with load balancing using the Dual Wan system I have had trouble staying connected to some secure sites. After doing some searching I found that the potential issue is the IP change mid session.
"http://www.broadbandreports.com/forum/r25537589-Cisco-RV042-can-not-use-load-balancing-for-some-web-sites"
Although my interface is significantly different I was able to find the same area in my RV042 admin area however, it doesn't seem to work.
System Management
> Dual Wan
In Wan 1 & Wan 2 I have HTTPS and HTTPS Secondary all forwarded to use Wan 2 under Protocol Binding
This however has not managed to do anything at all for my network and every computer conneceted experiences the same HTTPS irregularities at some websites.
I'm sure I must be doing something wrong, but I don't know what it is.
Both incoming connections are from the same service provider although the plans are different.
Any help with this would greatly help me stop losing my mind trying to fight with my website control panel for 10 minutes to just login and get something done.
Thanks

Any ideas or advice from anyone?
