介绍了移动IP网络与多协议标签交换(MPLS)技术相结合给网络带来的巨大的性能改善。首先,介绍了移动IP技术的特点,主要包括地址自动配置、邻居发现、动态归属代理地址发现机制等。指出了其存在的不足之处,主要有切换性能不佳、数据传输速率较低、安全保障差。其次,介绍了MPLS网络的构成框架和主要的技术特点,如转发等价类、标签转发和标签交换等。重点介绍了上述两种技术融合所产生的新网络体系结构,以及新网络结构下的移动IP绑定更新、数据传输流程和隧道技术。最后总结得出了新网络体系结构的优越性。
Introduced the mobile network and multi-protocol label switching (MPLS) technology combined to the network to bring huge performance improvements. First of all, introduces the characteristics of mobile IP technology, including address autoconfiguration, neighbor discovery, dynamic home agent address discovery mechanism. Pointed out the shortcomings of its existence, mainly switching performance is poor, the data transfer rate is low, poor security. Secondly, it introduces the composition framework and main technical features of MPLS network, such as forwarding equivalence class, label forwarding and label switching. The new network architecture resulting from the convergence of the two technologies mentioned above and the mobile IP binding update, data transmission process and tunneling technology under the new network structure are mainly introduced. The conclusion is drawn that the superiority of the new network architecture.
