Abstract: In an exemplary embodiment, a method for managing a network includes monitoring a network using an interior gateway protocol to detect change in the network, and determining effects of the detected network change on Multi Protocol Label Switching paths in the network. For example, the MPLS paths can be the same as IGP best paths. An exemplary embodiment includes managing a Multi Protocol Label Switching network by discovering edge routers in the Multi Protocol Label Switching network, determining possible combinations of Multi Protocol Label Switching path end points based on services provided within the network, selecting discovered edge routers for observation, based on the determined possible combinations, monitoring the selected edge routers, and determining status of Multi Protocol Label Switching paths in the network based on the monitoring.

An exemplary method includes identifying a first address associated with a subnet; determining a length of a prefix part of the first address; determining a length of a prefix part of a second address; determining when a portion of the second address matches a portion of the first address; and determining when the lengths of the prefix parts of the first and second addresses are equal. A relationship between the second address and the subnet is inferred when the portion of the second address matches the portion of the first address and the lengths of the prefix parts of the first and second addresses are equal.

Abstract: A system and method for communicating between a management station and at least two networks having duplicate Internet Protocol (IP) addresses. An IP address for an IP data packet to be sent to at least one of an end device and the management station is recognized. A header of the IP data packet with a tag that identifies one of the duplicate IP networks within which the end device resides is modified. The IP data packet is routed, based on the tag, in accordance with a policy.

Abstract: In a computing platform, a trusted hardware device (24) is added to the motherboard (20). The trusted hardware device (24) is configured to acquire an integrity metric, for example a hash of the BIOS memory (29), of the computing platform. The trusted hardware device (24) is tamper-resistant, difficult to forge and inaccessible to other functions of the platform. The hash can be used to convince users that that the operation of the platform (hardware or software) has not been subverted in some way, and is safe to interact with in local or remote applications. In more detail, the main processing unit (21) of the computing platform is directed to address the trusted hardware device (24), in advance of the BIOS memory, after release from ‘reset’.

Abstract: One embodiment disclosed relates to a method of configuring a network including multiple overlapping private address domains. A configuration file is created for each overlapping address domain (OAD). The configuration file includes an identifier for the OAD, a gateway address to the OAD, and mappings between private addresses in the OAD and corresponding management addresses. Another embodiment relates to a system for managing a network including multiple OADs. Another embodiment relates to a method of processing a trap from a network with multiple OADs. Another embodiment relates to a method of finding an active route across a static NAT device.
