【摘要】：IETF提出了基于路径计算单元(path computation element)的多域光网络架构方式,能够很好地解决跨域路由的计算问题;但由于光网络的透明性,分层PCE架构下的光网络存在安全威胁。因此,如何提高光网络中信息传输的安全性是一个重要的问题。在PCE架构的基础上,利用信任度、接种疫苗及免疫选择等关键技术,设计了多约束条件下基于人工免疫和信任度的多域光网络安全组播路由算法;在保证光树可信和高收敛速度的前提下,可使组播树的综合成本最小。经分析及仿真实验表明,与传统的多域光网络最短路径树组播路由算法相比,具有更低的综合成本和更优的抗阻塞性能。
[Abstract]:IETF proposes a multi-domain optical network architecture based on path computation element, which can solve the computing problem of cross-domain routing. However, due to the transparency of the optical network, there is a security threat to the optical network under the layered PCE architecture. Therefore, how to improve the security of information transmission in the optical network is an important issue. On the basis of the PCE architecture. Based on the key technologies of trust, vaccination and immune selection, a secure multicast routing algorithm for multi-domain optical networks based on artificial immunity and trust is designed. On the premise of reliable and high convergence rate of optical tree, the synthesis cost of multicast tree can be minimized. The analysis and simulation results show that compared with the traditional multicast routing algorithm of shortest path tree in multi-domain optical network. It has lower integrated cost and better anti-blocking performance.
