I have got a request from a customer who have bought a HD video conferencing solution. We have 3 sites and 1 hosting site where all their servers are located.
The conenctions between these sites are via IPsec tunnels (Cisco firewalls) on 30 Mbits internet connection without any QoS.
He is not satisfied with the video conference performance as the video and audio is choppy and sometimes blurry.
So I am about to sell him a router based VPN solution based on GRE tunnels over IPsec with QoS in a full mesh VPN solution possibly using EIGRP for dynamic routing.
I need to do some LLQ on the EF traffic from the video conferencing system (which according to my readings show a load of between 10-20 Mbit/s, depending on if it is P2P og multipoint conferencing) and at the same time do some CBWFQ on ICA traffic going to the hosting site, while also preventing bursty traffic like FTP and windows printing from affecting Video and ICA traffic.
I am thinking of using 2801 routers (with VPN-AIM and Adv. IP Services IOS) at the 3 customer sites and a 2821 router on the hosting site (also with VPN-AIM and Adv. IP Services IOS).
however I am unsure if these routers are sufficient to handle both the QOS, GRE and IPsec. Can anyone please give me some advice on this - and in case they aren't sufficient tell me which router model I should go for instead.
I really need urgent help on this as my customer is desperate to get my proposal :)
Thanks for any help in advance...
