基于SDN的链式快速转发网络模型研究

针对当前网络中降低数据包传输时延的机制复杂且在数据包的匹配过程中存在较高的处理时延,提出了基于软件定义网络(SDN)架构的虚拟链式快速通道路由模式(Chain-Like Hyperchannel Routing Mode,CHRN),在将不同优先级的数据流映射到不同的虚拟传输网络上的同时,时延敏感型数据将采用不查表的快速转发方式来降低数据包的处理时延.实验证明,这种方式在不影响普通数据包传输的条件下,有效提高了时延敏感型数据的传输效率.     

Local networking at the Royal Bank of Scotland

Data communications facilities are vital if essential banking operations are to be computerized; branches and head offices that are dependent upon terminals and corporate data to fulfil their functions must have access to such facilities. Back-up facilities are also essential if normal bank functions are not to be disrupted should a fault develop. Investigations that led to the installation of Hyperchannel at the Royal Bank of Scotland are described and the problems to which Hyperchannel provided the solutions are examined. The implementation of the system and plans for future development are discussed.
