  • Patent number: 7016980
    Abstract: A method and apparatus are disclosed for analyzing the operation of one or more network gateways, such as firewalls or routers, that perform a packet filtering function in a network environment. Given a user query, the disclosed firewall analysis tool simulates the behavior of the various firewalls, taking into account the topology of the network environment, and determines which portions of the services or machines specified in the original query would manage to reach from the source to the destination. The relevant packet-filtering configuration files are collected and an internal representation of the implied security policy is derived. A graph data structure is used to represent the network topology. A gateway-zone graph permits the firewall analysis tool to determine where given packets will travel in the network, and which gateways will be encountered along those paths.

  • Patent number: 6915348
    Abstract: An OP-N connection is mapped through a communications network between first and second end-nodes via at least one intermediate node. The integrity and validity of the OP-N connection can be determined independently of SONET/SDH lines, sections or paths mapped through the network, and potentially utilizing bandwidth of the OP-N connection. Validation of the OP-N connection can be accomplished by inserting performance monitor (PM) information into a data signal at the first end-node. The PM information is inserted into the synchronous payload envelope (SPE) of a SONET/SDH data signal. At each intermediate node between the first and second end-nodes, the PM information may be extracted, examined and/or augmented or simply pointer processed before the data signal is forwarded. At the second end-point, the PM information is extracted and examined. Multiple levels of OP-N connections are supported, with each level being provided with a respective set of PM information carried in the SPE.
