全光网络中一种新的信令嵌入预留协议的研究

为了提高波长路由网络的性能，在后向预约机制的基础上，提出了一种新的信令嵌入预留协议(SNRP)的构想。为使网络更具可靠性，这种预留方式采用分布式控制机制，主要面向于具有远距离节点的WDM核心网络。详细描述了嵌入式预留协议(NRP)和信令嵌入预留协议(SNRP)，并作出了在不同网络流量的情况下，分别采用SNRP和NRP协议时，网络传送非实时数据包的时延比较和拥塞率的比较，仿真实验表明，使用SNRP能充分地提高网络效率。

Study of new signaling nested reservation protocol for all-optical networks

On the basis of backward reservation protocol,a new signaling nested reservation protocol is proposed,To be more robust and reliable,the proposed approach employs distributed control mechanisms.This paper describes NRP and SNRP in detail,as well as compares their transmission delay and blocking probability when transmitting unreal-time data packets under different traffic loads.Simulation experiment shows that SNRP can improve the performance of network efficiently.
