    摘要: A system and computer program product for monitoring and optimizing performance and availability of a Dynamic Host Configuration Protocol (DHCP) service are provided by one or a plurality of DHCP servers in an Internet Protocol (IP) network comprising one or a plurality of IP subnetworks. The system implemented in hardware, comprises a computer infrastructure operable to define one or a plurality of groups of subnetworks, each group of subnetworks comprising one or a plurality of subnetworks. The computer infrastructure is further operable to retrieve information related to resources, in particular IP addresses, allocated within a DHCP server to each group of subnetworks. The computer infrastructure is further operable to transfer the information to a DHCP service monitoring system, the DHCP service monitoring system comprising means for retrieving the information from the one or a plurality of DHCP servers and means for aggregating the information for each group of subnetworks.

    摘要: A method and system for preventing unauthorized dynamic host configuration servers from responding to client configuration requests in an Internet Protocol (IP) network. In accordance with the method of the present invention multiple network clients are simulated within a server checker client. At least one unauthorized dynamic host configuration server is then detected utilizing the server checker client within said IP network. Upon detection of an unauthorized dynamic host configuration server, configuration requests are delivered from the server checker client to the detected unauthorized dynamic configuration server such that the unauthorized dynamic host configuration server is unable to respond to configuration requests from actual network clients.

    摘要: A method and system for enabling interconnection of VPNs is disclosed. An interconnection device manages an interconnection process at one or more facilities including, for example, a gateway device. The gateway device has information relating to a plurality of VPNs, and may facilitate interconnection between devices on at least two of the VPNs by determining that one device is in fact a member of a first one of the VPNs, and by forwarding connection parameters of the first VPN to the second VPN on an as-needed basis. In this way, the gateway allows interconnection without the need for a completely centralized decision-making process, and does so independently of the type of device and/or VPN(s) being used. Moreover, the gateway may implement only those VPN parameters needed by both VPNs to communicate with one another with a desired level of security, thereby simplifying the routing and forwarding processes associated with the actual communication occurring via the interconnection. The information related to the plurality of VPNs and their respective member devices may be stored in a mapping table at the gateway, and identification parameters of a device seeking interconnection and/or associated VPN parameters may be verified by the use of digital certificates.
