| 摘 要： | 为了在automatically switched optical network (ASON)网络中支持一个呼叫请求对应多条相同属性连接的情况，提出了连接批处理的概念，并扩展了信令消息及处理流程. 搭建了15个节点的试验平台，采用resource reservation protocol traffic engineering (RSVP TE)、open shortest path first traffic engineering (OSPF TE)及link management protocol (LMP)等协议实现ASON网络的控制平面. 实验数据显示，一个呼叫对应多条连接的连接批处理过程与传统的一个呼叫对应一条连接的情况相比较，不但节省了信令通信网的带宽，而且节省了连接的建立时间.

| Abstract: | The concept of connections batched is proposed to support multiple connections in a call session in automatically switched optical network(ASON).To support a call request having multiple similar connections,the function of component and procedure of signaling perform are extended.A test-bed of 15 nodes is built,the control plane of ASON by running resource reservation protocol-traffic engineering(RSVP-TE),open shortest path first-traffic engineering(OSPF-TE) and link management protocol(LMP) is implemented.The experimental results shows that multiple connections per a call have less connection setup time and network traffic than one connection per a call have. |
