Jing Shen, Thanks for your help! > >>Incoming packet is classified according to SLA. >>So, how can we determine the SLA according to the resources of the domain? > >If a company's network is connected to ISP, the SLA is negotiated between ISP and customer before any traffic happens. Base on SLA policy could be set up in BB and traffic classification rules could be set up in edge router. > >On the other hand, if dynamic negotiation is supported dynamic SLA negotiation could be done between BBs, which set up traffic classification rules in correponding edge routers. > I m still confused that how can we decide the correct SLA, then add the corresponding policy to the edge router? Can you introduce some algorithms for BB and custom to negotiation SLA, then setup policy Base on SLA and the resources of domain? >>>how can the resource be reserved in the interior router? >>it does not reserve any resource for special flow but share resource between service class. >>I know it does not reserve resource for microflow,but how can it reserve >the resources for the aggregate flows(the special class)? > >The BW is allocated between service classes, e.g. Premium, BE etc. There has been some BW allocation policies defined, as Russian Model, MAM , MAR etc. This models is used in DiffServ with MPLS,but not in DIffserv its self, is it right?
