GFA General Frame Allocation

By MPλS technology and OCDM,optical label switching is carried out in multiple dimension, in which less wavelengths are used; Algorithms for network topology discovery and multi-LSP tunnel establishment are provided; GFP is extended and re-defined to perform traffic engineering.

对MPλS进行扩展,提出基于GMPLS的新型二维标记交换(MPCλS:Multi-Protocol Code-λ Switching),利用光码分复用(OCDM)结合MPλS对数据进行复合多维度的标记交换,降低了所需波长数;给出网络拓扑发现和复合LSP的建立过程算法,实现资源的灵活配置;引入通用成帧规程(GFP),并对其进行扩展改进,实现对新型二维标记交换网络的流量整形。

The new generation MSTP adopts protocols and standards such as Generic Framing Procedure (GFP), Virtual Concatenation (VC) and Link Capacity Adjustment Scheme (LCAS).

文章分析了被应用在新一代多业务传送平台中的新的协议和标准通用成帧规程(G FP)、虚级联(VC)和链路容量调整规程(LCAS),认为将GFP、VC和LCAS技术与可靠的SD H平台结合,使传统的SDH可以较为完美地承载数据业务,为SD H带来新的发展机遇,也使M STP成为城域网最佳解决方案之一。

As the technologies of GFP, VCat, LCAS, RPR, MPLS and ASON have developed quickly, next-generation MSTP will adopt them gradually.

随着通用成帧规程(GFP)、虚级联(VCat)、链路容量调整(LCAS)、弹性分组环(RPR)、多协议标签交换(MPLS)、自动交换光网络(ASON)等技术国际标准的相继推出,新一代MSTP设备将逐步采用这些核心技术,面对新时期城域网IP业务大量兴起,MSTP逐步从简单透传、汇聚、共享发展到带宽管理,具备面向数据优化的传送能力。
