摘要： A solution for virtual router redundancy for server virtualization includes, at a network device configured as a backup router of a virtual router, examining a packet stored in a memory of the network device. Responsive to the examining, the network device determines whether to forward the packet via a network towards a destination or to send the packet via the network to a master router of the virtual router for forwarding of the packet, by the master router, towards the destination.

摘要： An example network node includes multiple line cards that learn Medium Access Control (MAC) addresses in a distributed manner. In an event a software upgrade is to occur, which requires a processor having the MAC addresses on the line cards to reboot, the line cards transfer the learned MAC addresses to a supervisory control card that normally does not know the MAC addresses. After the reboot, the line cards retrieve the MAC addresses, saving the line cards from having to relearn the MAC addresses.

摘要： The present invention provides a method, system, and computer program product for reliably and efficiently serializing access to data structures (i.e. updates and retrievals) without requiring searchers to use locks. The disclosed technique ensures that the contents of the data structure remain valid during access operations, yet does not require searchers to perform compute-intensive comparison operations to determine validity. Two trees are used at all times. Searches proceed against a first tree, while the second tree is used for performing updates. The steps required to carry out a particular update operation are stored as a queued transaction. When the update to the second tree completes, the trees are switched. The queued transaction is applied to the now-out-of-date tree, such that the nodes of this tree do not need to be searched or otherwise evaluated in order to perform the update, thereby optimizing the process of bringing this tree into synchronization with the tree that is now being used by the searchers. The two trees are repeatedly switched as additional update operations are performed. Atomic operations are used to ensure proper synchronization between the search and update processing on the trees.

摘要： A method and system are disclosed for distributing load in a network. A set of routers are configured for providing IP gateway services to a set of hosts where each router in the set of routers all back up all the other routers in the same set. Each router in the set utilizes identical load distribution policies, load distribution properties and load distribution arrangement. A Load Distribution Function (LDF) master router is determined for the set of routers, wherein each one of the set of routers is a backup for the LDF master router. Every router in the set of routers utilize the same algorithm to compute load distribution and the LDF master router provides balancing information to all the other routers by including that information in VRRP advertisement messages to all the routers.

摘要： A method or corresponding apparatus in an exemplary embodiment of the present invention determines how many copies of a multicast packet are to be sent, as copies, to multiple destinations based on information in the multicast packet and a group (e.g., bridge node) with which the packet is associated. The copies of the multicast packets are then generated. After generating the copies, an action to take for each copy is determined. This determination is made using the information in the multicast packet and based on the group with which the packet is associated. After the action is determined for each copy, the action is performed on each copy. Through use of an embodiment of the present invention, memory space is conserved, allowing for continued use of a device in a multicast environment of an ever growing network, such as the Internet.

摘要： A method of managing faults in a ring network may include configuring a ring network to be in a “horseshoe” topology by disabling a communications link from distributing media between a selected pair of adjacent nodes while allowing other communications or non-related media to continue to be distributed via the adjacent nodes. In the event of a failure, the disabled communications path may be re-enabled, and first or second backup communications paths may be employed, where the first backup communications path may use primary connections between adjacent nodes used for primary communications paths normally used to carry the media, and the second backup communications paths may use secondary connections between non-adjacent nodes. The disabled communications path may be dynamically moved in a logical or physical manner in an event of a communications link or node failure to maintain a “horseshoe” topology in the ring network.

摘要： The present invention provides a system, method and computer program product for managing multi-dimensional data. The management of the multi-dimensional data includes generating policy-compliant journal and accounting entries by processing the data segments of the multi-dimensional data. One or more data segments in the multi-dimensional data are assigned one or more keywords by a user. The keywords are combined with arithmetic operators to generate rules, based on predefined compliance policies. The rules are operated to generate one or more data outputs. These data outputs are posted as journal and accounting entries to a ledger.
