I will be implementing multicasting in our network and wanted to inquire about the implementation of QoS. Currently, QoS isn't implemented on any of the Routers and fair queuing is also disabled on all outbound interfaces. We have about 29 remote sited, some of which are linked via T1 (P-to-P), others via T1 (Frame-Realy), also other ones via DS3(P-to-Point), and the last via DS3(ATM).
My question, should I enable fair queuing on the outbound interfaces with the implementation of multicasting? If I were to enable fair queuing, are there any Caveat I should watch for????
Multicast, alone, doesn't really dictate the need for FQ (or QoS). What you should determine is whether there's any significant congestion that will be created when the multicast flow(s) is added to your existing traffic.
If you find that the multicast stream(s) makes some traffic have unacceptable performance, FQ, or a more complex QoS implementation, might be a solution. So might be the addition of bandwidth, or both.
Any caveats with FQ? The only major one is "ordinary" WFQ doesn't usually scale well with links faster than T1/E1 assuming the interface will accept it. FQ with CBWFQ does scale and can be used on almost all router interfaces.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
