Term question : carrier-class packet transport

What does "carrier-class packet transport" mean?  I am thinking maybe its how the heavy hitters (XO, SBC, Level 3) move packets on the internet, but I am guessing.
Thanks

Hi Jimmy,
From transformation to IP-based packet transport network (PTN) has garnered industry-wide attention as the most expedient remedy. PTN is generally regarded as a connection-oriented transport network technology. Based on IP technology, it is applicable to a multi-service environment and capable of accessing, converging and transporting "TDM/ATM over Packet" and "packet-only" services.
Nevertheless, IP technology possesses certain innate drawbacks that negatively influence its position as a carrier-class service transport mechanism
The features that PTN technology requires to render it carrier-class are detailed below.
1) Highly precise network synchronization
2) End-to-End QoS guarantees
3) SDH-like OAM and network protection
4) Uniform multi-service transport and management platform
Check out the below link for more information hope that clear out your query !!

  • Question about Classes

    I have a question concerning classes. In my main program I have a list box. I have gotten the index (using getSelectedIdex method) from the list box to use with my array. What I want to do is match the list box index with the array index to get the correct price from the array. I can do this in the main class, but was wondering if I could just do the calculations in another class. Can I pass the index of the list box to another class in order to do the calculations? I figure I could put the array in the other class too and match them. In order to do this, what would the class data member look like for the list box index that I have passed? I have tried and get errors, so was wondering if there was another way I can do this
    Thanks so much for your help

    class, but was wondering if I could just do the
    calculations in another class. Yes you can, but why? The only reason to do this from a design point of view would be to seperate the logic into another class so that;-
    1. you might reuse the class in the future.
    2. the main method class has become large and cumbersome making it difficult to find all the methods.
    3. There are a variety of methods and subroutines in your application so that the logic in your program will be improved in terms of readability and future maintenance by creating seperate class files.
    4. 'whatever' other reasons (?)

    Sooner or later the would-be java programmer has to change or make the transition from using java as a procedural language and develop programs along more OOP lines. The answer to your question is "yes of course you can do this" and simply from the point of view of learning how to pass an argument to a different class, then yeah, learn how to do this.

  • Capturing ABAP Class in Transport Request

    Hi ,
    Can anyone please tell me how to capture ana ABAP Class in transport request . IT first gave me an error saying :
    'ZCL_PHX_MANUAL_SAVE===========CO  missing then after capturing that , now it is giving me an error message saying
    'ZCL_PHX_MANUAL_SAVE===========CI missing.
    Can someone suggest me the correct method by which i can captur my class in request and transport it to Production.
    Thanks and Regards,
    Vijay Sanklecha.

    Hello Vijay,
    If your class name is ZCL_PHX_MANUAL_SAVE. Then SAP genereates its own includes for private,public and protected sections . Those are the includes that you have mentioned here.
    Right mehtod for including the class in a request is
    Go to Se80
              Give your class name anf right click
              Choose other functions-> write transport entry
    Regards

  • What is the difference between Service Edge Optimized line cards and Packet Transport line cards in the ASR 9000

    Hi Folks,
    What is the deep dive difference between the service edge optimized cards and the packet transport line cards in the ASR 9000?
    I know that QoS is the difference in general, for example, the service edge optimized has advanced QoS features while the Packet Transport line cards has basic QoS features but I want to know some more details please.
    Thanks

    There are four main deiffences (unfortunately don't have a reference link).

  • Survey Question - Carry over data

    Hi,
    Is there a way to carry over responses/answers from a survey question from one slide to another? I have a scenario where users analyze a situation and note the problems (survey answers - ungraded) on one slide. I don't want them to see the answers to the scenario until the next slide but want them to remember what they've put in as the problems with the scenario. I've searched the forum but didn't see this situation. Thanks very much for any ideas.

    For short answer questions the value of the system variable cpQuizInfoAnswerChoice is the exact text that was entered, which is great news for you I suppose? Be sure to assign the value of that variable to a user variable before the next question is answered. That means that best event to trigger the action is the On Enter event for the next slide. As you perhaps know, there is no On Exit event possible for Question slides.
    http://blog.lilybiri.com/events-and-advanced-actions
    You will have to create an advanced action for that:  Assign v_answer1 with cpQuizInfoAnswerChoice
    And you'll need a different action for each question, even shared actions couldn't help you because a variable (it is the user variable v_answerx that will be different for each action) cannot be a parameter.

  • MenuStrip and a Question about Class win32_product

    Hello,
    I have a bunch of questions I'm hoping someone can answer.
    1.) I would like to add a menu separator and a checkbox under a dropdownitem for a toolstripmenuitem
         Similar to what you would see in ISE or Internet Explorer.
         I then need to pass the state of this checkbox into a function
    2.) I have created a file menu item and would like to create a separator and then add a list of MRU items restricted to only displaying the five previous opened config files.
    3.) Can someone propose an alternative to using the get-wmiobject win32_Product class
    The below function I wrote to get the Product Version for some VMware products, but it is slow making the initial connection.   Looking at the Uninstall registry key won't work because it doesn't contain the product version.
    I know it looks odd.  I could not find a good way to detect which servers the products were installed on.   So instead I pass the servers that would host these products based on our build standards.
    Function get-version($vcenter,$sso,$vum,$credentials) {
    Write-Host "Getting Version information. This usually takes awhile. Be Patient " -NoNewline
    $Roles = "VMware vCenter Server","VMware vCenter Inventory Service","VMware vSphere Web Client","vCenter Single Sign On","VMware vSphere Update Manager","vSphere Syslog Collector"
    $i = 0
    $output = @()
    $Servers = "$vcenter","$vcenter","$vcenter","$sso","$vum","$vum"
    $ErrorActionPreference = 'silentlycontinue'
    ForEach ($input in $Servers) {
    IF ($psversiontable.psversion.major -ge 3) { Write-Progress -activity "Getting Version Information - Takes awhile. Be Patient." -status $Roles[$i] -PercentComplete (($i / $roles.Length) * 100) } Else { ticker }
    $object = New-Object PSObject
    $object | Add-Member NoteProperty "Role" $Roles[$i]
    $object | Add-Member NoteProperty "Hostname" $Servers[$i]
    $object | Add-Member NoteProperty "IP Address" (Get-WmiObject Win32_networkadapterconfiguration -ComputerName $Servers[$i] -Credential $credentials | ? {$_.IPEnabled} | Select-Object IPaddress).IPaddress[0]
    $object | Add-Member NoteProperty "Version" (Get-WmiObject win32_Product -ComputerName $Servers[$i] -Credential $credentials | Where-Object {$_.Name -eq $Roles[$i]}).version
    $output += $object
    $i++
    IF ($PSVersionTable.PSVersion.Major -ge 3) { Write-Progress -activity "Completed Getting Version Information" -Completed } Else { write-host "...Done!" -NoNewline }
    write-host ""
    $output
    } # End Function get-Version
    Walter

    Your code doesn't relay make much sense.
    What is this line for:
    $Servers = "$vcenter","$vcenter","$vcenter","$sso","$vum","$vum"
    Funtion get-version($vcenter,$sso,$vum,$credentials
    Why are you using credentials.  Only and admin can call remotely?
    Are you trying to get all of these roles? Aren't these produces?
    $Roles  = "VMware vCenter Server","VMware vCenter Inventory Service","VMware vSphere Web Client","vCenter Single Sign On","VMware
    vSphere Update Manager","vSphere Syslog Collector"
    ¯\_(ツ)_/¯

  • A question about class and interface? please help me!

    the following is program:
    interface A{
    public class B implements A{
    public static void main(String [] args){
    A a = new B();
    System.out.println(a.toString());
    }i want to ask a question, the method toString() is not belong to interface A, why a can call method toString()? the interface call the method that isn't belong to, why? please help me...

    because a.toString() call the method toString() of class Object because B implements A, but extends Object and in the class Object there is a method toString(). infact if you override the method toString() in class B, a.toString() call toString() in class B.
    try this:
    interface A {}
    public class B implements A
      public String toString()
        return "B";
      public static void main(String [] args)
        A a = new B();
        System.out.println(a.toString());

  • Package Class in Transport Collector

    When i Collect my Objects in the Transport Collector, I find that many of them are attached to a different Package class. there many such sub objects too. some of them i changed by right click -> change object directory. but some 300+ objects are still residing in another package.
    CAN I change the same by updating a table called TADIR by writing an ABAP code ??
    Or shud i continue to manually change the class.
    Pls advice. thanks.

    Hi,
    if you change the object directory entry (e.g. package of an object), the SAP system is doing some more things than just changing the TADIR table: it is locking the object and connecting it to a transport request, also some checks are performed, e.g. whether the namespace of the package is allowed for the object. To avoid inconsistencies, I would <b>not</b> prefer writing an ABAP in this case.

  • Question on WF_EXTSRV - Task (Transporting this task)

    Good day,
    I have implemented a workflow that calls a Webdynpro application.  I have done the required configuration in WF_HANDCUST and WF_EXTSRV (and also generated the task). The process has been tested successfully.
    My question is on moving this developement to the rest of my landscape (to QAS, PRD).
    The task that is created in WF_EXTSRV is w.r.t. to the Logical system of the Dev client and will not work with QAS, PRD. Can you please advise how we can move such developements.
    Also WF_HANDCUST are system specific configuration. Is this a config that Basis takes care of in your systems (Dev, Qas, Prd) ?
    Appreciate your help guys!
    Rgds, Liz

    All,
    Resolved this. Here is the solution -
    It came down to bad/missing entries in table SWLWPTSSID. This is the table that links the web service maintained in WF_EXTSRV with the workflow task. As it is a client-dependent setting, when you transport the task and webservice you also need to adjust this table using transaction SM30.
    Cheers, Liz

  • A basic question of class

    Hello guys,
    i'm new hand and i got this question but i'm not sur of the answer, any help would be welcome :)
    The correct statement(s) are:
    a: a class is an instance factory
    b: a class is a template for creating an entity
    c: a class is a set of all the instances of a pattern
    d: none of the above

    It is A or B. I'm not sure which one though because it is a strange question.
    A class is a piece of code that creates objects. It's like a factory that produces a certain type of object. It is like the blueprints. Every building has blueprints. When the builders build a building they look at the blueprints to see how it is done. The compile looks at a class as blueprints on how to make something. Think of Terminator 2. One class would create the t1000 robots and another class would create the t2000 robots.
    I hope that helps. I think that A and B could be equally right.

  • Question about classes/Directories

    I've been using Java to learn programming for a while now, so this question may not belong here. It seems to be more of a general question, however, not code related.
    How does java work with directories? Say I had a project, and for some reason I wanted different java class files to be in different directories. How does java handle this? Say for example:
    1.) Main class is in C:/blahblah/Project/ and the other classes were in C:/blahblah/Project/src/?
    2.) Main class is in C:/blahblah/Project/src/ and the other classes were in C:/blahblah/Project/?
    3.) Main class is in C:/blahblah/Project/src/ and other classes were in C:/blahblah/Project/bin/?
    I know these may be kind of stupid examples, but I just wanted to know how such things worked for future reference. Thanks a ton!

    {color:#3D2B1F}It sounds like you need to learn about packages: [http://java.sun.com/docs/books/tutorial/java/package/index.html] {color}

  • Protocols involved in carrying media packets while media traversal in a A/V call!

    Hi ,
    Am really confused about the the protocols..involved in the media traversal. Theres a whole lot protocols involved in the media traversal like UDP[fire and forget], TCP[handshake needed], SRTP[securing the RTP].  the scenario is when user A initiates
    the Audio call to user B] Am aware of the STUN TURN ICE concept. My concern is media.
    My doubt is...
    The "media packet" consists of what? -which protocol secures it.? Which carries the media packet to the endpoints??
    Something should "wrap" the media packets safely to the destination with a secured protocol. A simple explanation needed.
    -Prav

    The real physical media packers are UDP which wrapped around SRTP to encrypt the traffic.
    "SRTP is not a transport, it is simply the encryption of the RTP to secure it, hence the S before RTP. The RTP is still transported in UDP but both parties to the call have exchanged keys in the SIP to enable encryption. You can use SRTP regardless
    of the transport used for the SIP as they are unrelated. However, there is little value to encryption of audio with keys that are exchanged in plain text – anyone sniffing the SIP has the key to decrypt the SRTP. Therefore SRTP really should be used over and
    above TLS transport of the SIP leg."

  • A question about classes

    Hi all,
    This is a general question, hope it is in the right forum.
    Lets say I have a main document class, declared in the property window. I can easily create new instances of a movieclip in my library by simply creating them in my document class and then using addchild to put them on the stage. Now lets say I have a separate external class that I am importing into my document class. How do I create instances of the movieclip from my library in that external class. All I want my document class to do is import classes and let them do the work so to speak. I know I can create the movieclip instance in the document class and pass it as a parameter when I import the external class but what if I want to create it there?
    I hope that makes sense, I am sure it is very simple but I am tired of having massive long document classes!
    Thanks in advance.

    Hi, sorry I know you answered this but I have just done a quick test file to try the instantiation,
    the movieclip is not showing, the movieclip is linked out with a class of mcSquare.
    //document class
    package {
        import flash.display.MovieClip;
        import external;
        public class document extends MovieClip
            public var externalClass:external = new external();
            public function document()
    //external
    package {
        import flash.display.*;
        import flash.utils.getDefinitionByName;
        public class external extends MovieClip
            public var square_mc1:mcSquare = new mcSquare();
            /*public var square:Class = getDefinitionByName("mcSquare") as Class;
            public var square_mc1:Object = new square();*/
            public function external()
                //square_mc1.x = 43.5;
                //addChild(DisplayObject(square_mc1));
                addChild(square_mc1);
    The commented code is just attempts after googling.
    Again apologies for reposting, I thought that had cracked it
    Thanks

  • Wrong Development class in Transport request

    Hi Gurus,
             I had to change the Info OBject to meet the business requirement(Enabled Text Master Data). While creating transport request, I enteres wrong development calss in treansport requset. No transport request were released to QA. Now how to fix this issue, I mean How to enter the right Development class for the Info Object?
    Thanks in advance.

    dear Raj,
    you can change the development class/package with
    rsd1 (for characteristic), rsd2 (keyfigures),
    type in your infoobject name, and click button 'object directory entry' in top menu, in next screen click pencil icon ('change/display' F6) and choose/type in the right development class/package and 'save'.
    hope this helps.

  • Function Module / Class for Transport Management

    Hello,
    I have a requirement where I need to fetch the list of transports which are released. In addition to that, I also need to fetch list of object under each transport (which have failed to be migrated in the target system) and find all the relevant transports for that particular object type (Report, FM , Table etc) and display the list probably in an ALV report.
    Now, I know that accessing E070, E071 like E07* tables would probably match with my requirements.
    But I would like to implement the same using Classes in the first place (CL_CTS*) and if not, using Function Modules. Can someone give me any Class name(s), FM name(s) which would suit this requirement? Thanks.
    Regards,
    Venkata Phani Prasad K

    Hi Venkat,
    Try with the FM - TRINT_SELECT_REQUESTS, and look at the other FMs in the function group SCTS_REQUEST_SELECTION.
