Abstract

Currently, GMPLS is being developed as a standard in order to introduce intelligence for next-generation ASON (automatically switched optical network) by means of a distributed optical control plane, allowing, among other functionalities, dynamic and real-time provisioning of high-bandwidth optical connections. The provisioning of bidirectional optical connections over unidirectional OADM (optical add drop multiplexer) rings using a distributed GMPLS-based control plane has not yet been considered in the existing literature. We present two enhancements to GMPLS signaling which allow a dynamically bidirectional lightpath setup to be requested over a unidirectional ring. These new distributed signaling schemes introduce a new concept of the label contention problem applied at wavelength sets. The paper presents and compares new strategies of label contention policies for wavelength sets, providing a significant improvement in performance evaluated in the GMPLS control plane of the EMPIRICO project testbed.

在experiico ASON测试平台上实现了两种新的GMPLS光路设置协议，用于Metro-DWDM DPRing软永久连接

目前，GMPLS正在作为一种标准进行开发，以便通过分布式光控制平面为下一代ASON(自动交换光网络)引入智能，在其他功能中，允许动态和实时地提供高带宽光连接。现有文献中尚未考虑使用基于分布式gmpls的控制平面在单向OADM(光加丢复用器)环上提供双向光连接。我们提出了GMPLS信令的两个增强功能，允许在单向环上请求动态双向光路设置。这些新的分布式信令方案引入了波长集上标签争用问题的新概念。本文提出并比较了波长集的标签争用策略的新策略，在GMPLS控制平面上的性能评估中提供了显着的改进。
