摘要: 针对SDL协议中存在的问题, 对其协议机制进行了研究和改进, 增强了承载不同网络协议的通用性, 提高了网络自身纠错能力. 研究了头部CRC检错和纠错问题, 以及MPLS标签在SDL协议中的应用问题, 给出了一种头部CRC纠错及MPLS标签在SDL协议中的使用方法. 最后提出了一种能够识别MPLS标签的SDL协议实现方案.

Abstract: Aiming at solving the disadvantages in the SDL protocol, we study and modify the protocol mechanism,which enhances the flexibility in carrying the packets of various network layer protocol and improves the ability of error correction.We research the error check and error correction of CRC and the application of using MPLS labels in the SDL protocol. Furthermore, we provide a method of CRC correction and application of using MPLS labels in the SDL protocol.Finally,we present a scheme of realizing the SDL protocol.

Key words: communication protocols, SDL, MPLS, CRC
