Abstract :
Three requirements for leased-line service in a packet-transport system are determined such as service availability of 99.999%, bandwidth guarantee of 100%, and latency of 10 ms via 20 nodes. To meet these requirements, network architecture is proposed which includes the separation of control function and data-transmission function and shaping per flow at the entrance of a network. Nodes and gateways were implemented according to the proposed network architecture. Shaper functionality in the gateway was evaluated by experiment, and the validity of the shaper for delay reduction was confirmed. Our implementation revealed that it is possible to suppress delay time to 0.5 ms at a node by shaping user data flows at the entrance of the network. This shows the possibility that the bandwidth guarantee of 100% and latency of 10 ms via 20 nodes can be realized.
