摘要： The present invention provides a method and apparatus for a distributed virtual home agent. One embodiment of the method includes implementing a first primary home agent on a first portion of a plurality of hardware elements that operate according to a mobile Internet Protocol (IP) and a second primary home agent on a second portion of the plurality of hardware elements. A first backup home agent is implemented on the second portion of the plurality of hardware elements and a second backup home agent is implemented on the first portion of the plurality of hardware elements. Packets addressed to the first or second primary home agent can be directed to both the first and second portions of the plurality of hardware elements so that states of the first and second backup home agents mirror states of the first and second primary home agents, respectively.

摘要： Apparatuses, methods and articles of manufacture for performing data leakage prevention are provided. Data leakage prevention may be performed by determining a signature of a transmitted document, the transmitted document being in transit to a location beyond a network boundary. The signature of the transmitted document is compared with one or more signatures of documents authorized to be transmitted beyond the network boundary. The transmitted document is prevented from being transmitted beyond the network boundary if the signature of the document does not correspond to a signature of a document authorized to be transmitted beyond the network boundary.

摘要： A capability is provided for providing transparent cloud computing with a virtualized network infrastructure. A method for enabling use of a resource of a data center as an extension of a customer network includes receiving, at a forwarding element (FE), a packet intended for a virtual machine hosted at an edge domain of the data center, determining a VLAN ID of the VLAN for the customer network in the edge domain, updating the packet to include the VLAN ID of the VLAN for the customer network in the edge domain, and propagating the updated packet from the FE toward virtual machine. The edge domain supports a plurality of VLANs for a respective plurality of customer networks. The packet includes an identifier of the customer network and a MAC address of the virtual machine. The VLAN ID of the VLAN for the customer network in the edge domain is determined using the identifier of the customer network and the MAC address of the virtual machine. The FE may be associated with the edge domain at which the virtual machine is hosted, an edge domain of the data center that is different than the edge domain at which the virtual machine is hosted, or the customer network. Depending on the location of the FE at which the packet is received, additional processing may be provided as needed.

摘要： Packets are processed (e.g., routed or classified) in accordance with a braided trie, which represents the combination of two or more different original tries (e.g., representing different forwarding/classification tables). The different tries are combined by twisting the mappings for specific trie nodes to make the shapes of the different tries more similar. Each node in the braided trie contains a braiding bit for at least one original trie indicating the mapping for that trie's node. Trie braiding can significantly reduce the number of nodes used to represent the different original tries, thereby reducing memory usage and improving scalability. Braided tries can be used for such applications as virtual routers and packet classification in which different forwarding/classification tables are represented by a single braided trie stored in shared memory.

摘要： A capability is provided for representing a set of data values using data structures, including converting a binary trie data structure representing the set of data values to a shape graph data structure representing the set of data values. The shape graph data structure is generated from the binary trie data structure based on the shapes of the sub-trees rooted at the nodes of the binary trie data structure. The shape graph includes vertices representing shapes of the sub-trees of the binary trie data structure. A shape graph data structure permits operations similar to the operations that may be performed on the binary trie data structure for performing lookups for data values from the set of data values, while at the same time reducing the structural redundancy of the binary trie data structure such that the shape graph data structure provides significant improvements in memory usage over the binary trie data structure.
