Application Level Routing in a Mesh Router?

faisaladeem asks: "Are there such mesh routers that can re-route the traffic based on QoS? (I'm not talking about traffic shaping) For example, if data rate of a video stream decreases due to an increase in congestion along the path then the router will re-route the stream dynamically to a different path to ensure the QoS for the video traffic. Since a mesh network has many paths or routes, it can be assumed that a less congestive path can be found if the existing path becomes bandwidth constrained. I heard that MPLS supports this kind of functionality? Secondly, can a router estimate the latency/bandwidth on a specific route ?"

    I think there ar a few routers out there capable of something like that. Check out http://www.zytrax.com/features/qos.htm look slike it might be what you're looking for.

    As I understand it the mesh network makes use of multiple uncoordinated internet connections to provide internet connectivity for the nodes of the mesh. Although the edge nodes may co-ordinate with eachothers, the internet connections may be with various providers in various address ranges making it generally too-late to re-route once a stream has begun.

    If you control the network there are a lot of possibilities, including MPLS, but for a single user on a network there is not much that can be done as anything that is broadly accepted so that "it works" can be used by everyone and the problem is just reduced back to bandwidth contention.

    If bit-torrent becomes to slow compared to VOIP people WILL encapsulate it as some kind of VOIP protocol in order to use the faster network.

    If VOIP quality is good too many people WILL use it instead of regular telephone till the VOIP quality becomes poor.

    Commoditize the bandwidth (as my manager keeps telling me) and charge people for the quality of service they need. Variable price sounds scary compared to "all you can eat DSL" but it is the only model that will provide a service of the quality people need by charging what they are willing to pay.

    As long as the customer has choice over DSL provider it will be best for everyone as DSL providers get best return on best bandwidth utilisation and customers only pay a premium for highly contended service types, which stimulates provision of more service (to cash in on those prices) which in turn reduces the price.

    So you poor Americans stuck in cable-only DSL areas really really really need to write to your representatives and get competition opened up in your cable areas.

    I maybe talking through my hat, but it makes sense to me.

  3. Sandvine PTS - Probably overkill... by JFitzsimmons · · Score: 3, Informative

    Sandvine PTS

    Slightly more technical description of services provided. Notable quote: "QoS policies can be set for latency sensitive applications like VoIP and gaming."

    If you try to read through the buzzwordese it might actually make sense. Although, I think this is probably overkill for what you want.
