QoS issues, continued

• At the edge of the network:

  • Additional bandwidth
  • cRTP
  • Queuing (WFQ, CQ, PQ, CB-WFQ)
  • Packet classification (IP Precedence, policy routing, RSVP, IP RTP Priority)
  • Shaping traffic flows and policing (GTS, FRTS, CAR)
  • Fragmentation (MCML PPP, FRF.12, MTU, IP MTU)
  • Jitter control on end routers
