摘要： Systems, apparatus and methods for the implementation of high-speed network analyzers are provided. A set of high-level specifications is used to define the behavior of the network analyzer emitted by a compiler. An optimized inline workflow to process regular expressions is presented without sacrificing the semantic capabilities of the processing engine. An optimized packet dispatcher implements a subset of the functions implemented by the network analyzer, providing a fast and slow path workflow used to accelerate specific processing units. Such dispatcher facility can also be used as a cache of policies, wherein if a policy is found, then packet manipulations associated with the policy can be quickly performed. An optimized method of generating DFA specifications for network signatures is also presented. The method accepts several optimization criteria, such as min-max allocations or optimal allocations based on the probability of occurrence of each signature input bit.

摘要： There is provided a system and method for providing a simple yet flexible overlay network on top of any IP networks to enable diverse network applications whereby much of the rigidities of IP protocol suite are eliminated without any modifications to the applications. In particular, the system includes: a plurality of c-nodes; one or more source terminal nodes connected to an IP network; and one or more destination terminal nodes connected to the IP network. Here, the source terminal nodes send IP packets over the plurality of c-nodes to the destination terminal nodes to accomplish arbitrary communications between arbitrary groups of the source terminal nodes to arbitrary groups of the destination terminal nodes. More specifically, a method employing the system utilizes the concept of connection ID and headers that can be inserted anywhere in the IP packet.
摘要翻译：提供了一种用于在任何IP网络之上提供简单而灵活的覆盖网络的系统和方法，以实现不同的网络应用，从而消除IP协议组的大部分刚性，而无需对应用进行任何修改。特别地，该系统包括：多个c节点; 连接到IP网络的一个或多个源终端节点; 以及连接到IP网络的一个或多个目的地终端节点。这里，源终端节点通过多个c节点发送IP分组到目的终端节点，以实现源终端节点的任意组与目的终端节点的任意组之间的任意通信。更具体地说，采用该系统的方法利用可插入IP分组中的任何地方的连接ID和头部的概念。
