中国科学院声学研究所专利：基于openflow交换机的流表表项空闲超时检测方法
多单元散列表与TCAM结合的OpenFlow流表查找方法
OpenFlow 三态内容寻址存储器 散列表 流表
2016/12/3
在OpenFlow网络中，交换机通过标准化的接口接受基于流的规则，执行基于流的报文处理。流表的查找是OpenFlow交换机的核心功能，TCAM以其优异的性能广泛用于OpenFlow流表的查找，然而基于TCAM的OpenFlow流表查找具有较高的成本与能耗。为了降低流表查找的成本与能耗，提出了多单元散列表与TCAM结合的OpenFlow流表存储与查找的方法。通过理论分析与仿真测试，给出了查找结构成本...
Link failure detection in OSPF network using OpenFlow protocol
Link failure detection OSPF network OpenFlow protocol
2015/1/20
The study of this thesis is focused on reducing the link failure detection time in OSPF network. When a link failure occurs, OSPF protocol detects it using RouterDeadInterval time. This timer is fired...
