  • Patent number: 8824482
    Abstract: Methods and systems have been provided for removing dead Access Control Entries (ACEs) in an Access Control List (ACL). In one embodiment, the dead ACEs can be detected for an egress as well as an ingress ACL. The ACEs that have a hit count above a user-specified hit count are checked for their validity. The validity of the ACE is checked, using the information based on a Forwarding Information Base (FIB). If an ACE is found to be invalid, it is considered dead. The dead ACEs are referred as candidates for removal from the ACL. If the ACE is found to be a candidate for removal, a system administrator can either warn the network administrator about the candidate for removal or delete the ACE from the ACL after a pre-defined time limit.

  • Patent number: 8078679
    Abstract: In one embodiment of the invention, a method for automating collateral configuration in a network is provided. A service is configured on a network device (termed as service providing device). The service providing device sends a Collateral Configuration Request Protocol (CCRP) message to other network devices (termed as service accessing devices). The service accessing devices process the CCRP message for their automatic collateral configuration in order to access the configured service on the service providing device.

  • Patent number: 7971244
    Abstract: A method of determining network penetration (which may be carried on a computer readable medium) and an apparatus for performing the method are disclosed. The method includes the computer-implemented step of simulating a packet traveling in a network based on topology data and on security policy data, and providing output related to results of the step of simulating.

  • Patent number: 7680925
    Abstract: A method, system, and apparatus are provided for testing a service in a network. A simulated interface is created on a network device by a Network Management Station (NMS). Thereafter, an instruction is received at the simulated interface from the NMS. The instruction comprises a source address, a destination address and other information to test a service. The service is tested on the network device based on the received instruction. A response is generated from the test. The response indicates whether the service is working as intended between the source address and the destination address. The response is sent from the simulated interface to the NMS.
