Hi all, I was wondering if anyone could help me with a few quick questions regarding multicast support on TNTs. I'm new to the list, so apologies if these questions have been asked before... 1) Performance: Has anyone seen any performance problems with multicast on a loaded TNT? What would be the impact on performance if hundreds of dial-up users all join the same group (say a 40kbps video stream)? Would this situation hit performance more or less than if you had many streams each with only a few users? Any experience that anyone could share on these aspects would be very welcome... 2) Multilink PPP: I don't beleive multicast fowarding is supported on multilink PPP sessions (at least on our TNTs with 8.0.4), either (a) when all the sub-sessions terminate on the same box, or (b) when they terminate on different boxes in the same PoP ('stacking'). Has anyone else tried it and got different results? Thanks in advance for your thoughts... Tony. -- Tony Mills mills at albacom.net ------------+=+------------ Albacom SpA - Roma - Italia
