未来光网络的核心——GMPLS

GMPLS--The Core of the Future Optical Network

目前 ,大多数厂商和标准化组织都将目光集中在全光网络上 ,为了解决全光网络的管理问题 ,IETF提出了GMPLS解决方案 ,本文在比较了GMPLS与OIF等提出的重叠模型之后 ,通过控制平面的讨论引出了GMPLS的信令协议以及与传输域相关的一些主要特性 ,并对GMLPS的链路管理做了一定程度的展开。

Presently,most manufacturers and standardized organizations are focusing on all optical network(AON), so IETF has put forward GMPLS to solve the management about AON. After a comparison between GMPLS and OIF overlap model, introduced the GMPLS signaling protocols and characteristics correlated with transport domain, finally, discussed the link management protocol(LMP) detailedly.
