Multicast Traffic flow

Dear All,

i want to prepare multicast traffic flow from sender to receiver (IPTV user) logical diagram, so what information should have in logical diagram? is this diagram should be made in visio or ppt? is this diagram should have all physical devices from sender to receiver path?

 

thanks

    It depends on the purpose of the diagram, broadly if you are going to present this diagram to management then you may skip details such as ip addresses or layer 2 switches, only high level view could be appropriate. However if thiis diagram is for technical use then better to pun as many details as possible like all multicast routers, layer 2 switches, ip address etc for better understanding of the topology.

  • Hi,

    means i should mentioned source unicast ip, multicast group, directly connected switches, routers, core network, pop, access switches, STBs, right?

    is it ok if i prepare diagram as per particular source and multicast group address?

     

    thanks

     

  • Hi!

    Is the drawing for engineers or for customers/sales (management)?

    If it is for engineers you should provide ip addresses, group addresses, port numbers of the stream, rendezvous point info etc. If it is for sales etc. then you usually do not need ip addresses etc...then names are sufficient.

    Is the Mcast Traffic completely different for every source in your net?

    Hi,

    In what purpose you are doing this? I really recommend:

    Source IP, multicast group, connected switches (sender and receiver), all routers on transit path, if there is different multicast packet flow than unicast, config as well with physical devices.

    Good Luck.

  • Hello,

    thanks for suggesting.

    yes its for learning purpose and i prepared diagram with physical, IP, source and receivers details.

    thanks

  • Hi,

    can you please tell me meaning of flag TA
    how does its affect mroute entry, means what is the meaning of below entry?
