摘　　要：MPLS被认为是下一代IP骨干网络技术,它的出现为流量工程的应用带来了有力的技术支持,同时也能应用于提供服务质量保证和构建虚拟网。作为两种支持MPLS流量工程的信令技术,CR-LDP和RSVP-TE有着各自的优缺点。首先介绍了这两种信令技术的基本原理和技术特点,然后对它们在支持的服务模型、协议的可靠性、适应性、扩展性等方面进行了比较,最后指出了这两种信令技术综合应用的研究方向。MPLS is regarded as the core of the next generation IP network. Its emergence provides strong technical support for traffic engineering. It can also be applied in supporting QoS and VPN constuction. CR-LDP and RSVP-TE are two signaling protocols which are designed to support MPLS. But each coin has two sides, so it is with CR-LDP and RSVP-TE. First, the signaling procedures of the two signaling protocols were investigated, and then the adaptability, extension and reliability were analyzed and compared. At last, some future works were proposed to make best use of the two signaling protocols integratively.
