Since the existing anycast communication models can not achieve scalability and provide QoS guarantee simultaneously, an anycast communication model-SMA is proposed based on segmental measurement. The routing table is restricted by the competition among anycast group members, and only one winner can write its unicast address to the related routers. A method to estimate the variation upper bound of end-to-end delay is proposed. The anycast requests with QoS constraint are supported by measuring, sharing and estimating network parameters between routers and anycast members in a small region. Experiments on PlanetLab show that the proposed estimation method is accurate. Simulations in a nearly real Internet topology show that the SMA is efficient in the selection of best members and has good scalability and reliability as well.
