发明内容 各种计算机网络上的连接建立现在通过 GMPLS 来实现。该技术基于源路由方法，要求源节点在计算路由之前存储整个网络的度量信息。因此，所有度量信息必须分发到所有网络节点并保持最新。然而，随着度量信息变得更加多样化和普遍化，由于巨大的更新开销而很难更新所有信息。新兴的网络服务和应用要求网络支持多种指标以实现各种通信质量。增加网络支持的指标数量会导致指标更新消息的过度处理。为了减少度量更新消息的数量，需要另一种方案。本文提出了一种使用基于泛洪的信令而不是度量信息的分发的连接建立方案。所提出的方案仅需要具有所请求的度量信息的信令消息的洪泛，不需要路由协议。评估证实，所提出的方案无需过多开销即可实现连接建立。我们的分析表明，与传统的方案相比，所提出的方案大大减少了控制消息的数量。
SUMMARY Connection setup on various computer networks is now achieved by GMPLS. This technology is based on the source-routing approach, which requires the source node to store metric information of the entire network prior to computing a route. Thus all metric information must be distributed to all network nodes and kept up-to-date. However, as metric information become more diverse and generalized, it is hard to update all information due to the huge update overhead. Emerging network services and applications require the network to support diverse metrics for achieving various communication qualities. Increasing the number of metrics supported by the network causes excessive processing of metric update messages. To reduce the number of metric update messages, another scheme is required. This paper proposes a connection setup scheme that uses flooding-based signaling rather than the distribution of metric information. The proposed scheme requires only flooding of signaling messages with requested metric information, no routing protocol is required. Evaluations confirm that the proposed scheme achieves connection establishment without excessive overhead. Our analysis shows that the proposed scheme greatly reduces the number of control messages compared to the conven
