| 摘要: |
| 对自动交换光网络（AsON）中基于RSVP—TE的组播扩展进行了研究。提出了在现有信令架构上实现组播功能的几个关键问题，并就基本技术进行了讨论。在此基础上，介绍了4个RSVP—TE协议扩展模型，并通过仿真详细比较了它们的开销和性能。文中的理论分析和仿真结果对光网络中组播协议的设计和选择提供了重要的参考依据。 |

| Abstract: |
| Multicast extension based on RSVP -TE for MPLS/GMPLS is studied, which is the control plane of ASON. The key issues on multicast implementation are discussed in detail, with study on related essential techniques. Four solutions of multicast extension to RSVP - TE are presented, with detailed comparisons given by simulation. The analysis and simulation results presented in this paper can be used as basis for implementing multicast extensions to current RSVP -TE protocol, or, be used to select proper extension method under different requirements. |
