  • Patent number: 8982900
    Abstract: Routing around intra-network element (intra-NE) disconnectivity is described. The routing is performed on one or more network element (NEs) of a channelized network. The routing involves performing a shortest-path-search (SPS) to determine a shortest non-disconnected path from a single path-ingress edge to a single path-egress edge. The SPS includes classifying a set of endpoints of each NE in the channelized network as an equivalence class of endpoints, classifying a set of paths-so-far between each NE in the channelized network as an equivalence class of paths-so-far, grouping each equivalence class of paths-so-far by the equivalence class of endpoints that includes a terminal endpoint of the path-so-far that is furthest from the single path-ingress edge, and exploring separately each equivalence class of edges that are incident to each NE when determining the shortest non-disconnected path from the single path-ingress edge to the single path-egress edge.

  • Patent number: 8982734
    Abstract: Methods, apparatus and systems for routing information flows in networks based on spanning trees and network switching element resources. One or more controllers are used to assign information flows to network switching elements (NSEs) through use of spanning trees derived from link path costs. NSEs generate status information relating to resources they employ to facilitate information flows that is sent to the controller(s). The status information is used to derive link costs, which are then used to generate spanning trees that support routing between the NSEs without any path loops. Information flows are assigned to the NSEs such that the routing paths for the flows use the links in the spanning tree. The link costs and spanning trees are dynamically computed during ongoing operations, enabling the network routing and flow assignments to be reconfigured in response to dataplane events and changes to the information flow traffic.

  • Patent number: 8954515
    Abstract: An application proxy is disposed between a user device and an application server. The application server supports an application that is available on the user device. The user device registers with the application proxy for the application. The user device is prevented from transmitting application update request messages to the application server. The application proxy transmits application update request messages to the application server on behalf of the user device. The application proxy receives application update response messages from the application server. The application proxy determines, based on the application update response messages from the application server, whether to send an application update notification message toward the user device. In this manner, application update traffic normally transmitted via the network between the user device and the application proxy is reduced. The application update request and response messages may be polling messages, keep-alive messages, and the like.

  • Patent number: 8918634
    Abstract: A network node for communicating data packets secured with a security protocol over a communications network includes a host information handling system (IHS) and one or more external security offload devices coupled by a secure data link. The host IHS communicates state information about data packets, and the external offload security device provides stateless secure data encapsulation and decapsulation of packets using a security protocol. An external network interface controller or internal network interface controller communicates encapsulated data packets over the communications network to a final destination. Encapsulation and decapsulation of packets by the external security offload device reduces network latency and reduces the computational load on the processor in the host IHS. Maintaining state information in the host IHS allows hot-swapping of external security offload devices without information loss.

  • Patent number: 8862740
    Abstract: In a network, a user can configure host-level policies usable for load balancing traffic to servers of a domain. A global server load balancing (GSLB) switch provides load balancing to the servers, and is configured with the GSLB host-level policies. Users can define a host-level policy (alternatively or additionally to a globally applied GSLB policy) and apply the host-level policy to hosts in domains configured on the GSLB switch. Thus, the user can enable different policies for different hosts. This allows the user to have the flexibility to control metrics used for selection of a best address for querying clients, as well as the metric order and additional parameters used in the GSLB process, at the host level.

  • Patent number: 8832245
    Abstract: An authoritative domain name system server includes a memory configured to store a set of instructions, and a processor configured to execute the set of instructions. The processor obtains a first Internet Protocol address of a client system associated with a request for a domain name, and assigns a location of the authoritative domain name system server as an ingress region. The processor assigns the egress override as an egress region when the first Internet Protocol address matches the prefix of the egress override, otherwise obtains an egress table, determines a longest prefix match of the first Internet Protocol address, obtains a distance matrix for distances from the ingress location to a plurality of egress regions, and selects the egress region based on the distance matrix and the longest prefix match in the egress table.

  • Patent number: 8826003
    Abstract: A network node for communicating data packets secured with a security protocol over a communications network includes a host information handling system (IHS) and one or more external security offload devices coupled by a secure data link. The host IHS communicates state information about data packets, and the external offload security device provides stateless secure data encapsulation and decapsulation of packets using a security protocol. An external network interface controller or internal network interface controller communicates encapsulated data packets over the communications network to a final destination. Encapsulation and decapsulation of packets by the external security offload device reduces network latency and reduces the computational load on the processor in the host IHS. Maintaining state information in the host IHS allows hot-swapping of external security offload devices without information loss.

  • Patent number: 8819272
    Abstract: A parallel multiprocessor system includes a packet-switching communication network comprising a plurality of processor nodes operating concurrently in parallel. Each processor node generates messages to be sent simultaneously to a plurality of other processor nodes in the communication network. Each message is divided into a plurality of packets having a common destination processor node. Each processor node has an arbiter that determines an order in which to forward the packets onto the network toward their destination processor nodes and a network interface that sends the packets onto the network in accordance with the determined order. The determined order operates to substantially avoid sending consecutive packets from a given source processor node to a given destination processor node and to randomize the destination processor nodes of those packets presently traversing the communication network.

  • Patent number: 8819280
    Abstract: Techniques are provided for using the mobility support features of IPv6 to allow client and server nodes to communicate without the continuing intervention of a load-balancing node that selected the server node. A load-balancing node intercepts a TCP SYN packet addressed to a virtual IP address. The load-balancing node selects a server node from among multiple server nodes, and sends the packet toward the server node. The server node sends an IPv6 packet toward the client node. The packet contains a Binding Update option that specifies the virtual IP address as a Home Address. This information causes the client node to replace destination addresses in outgoing IP packets so that packets that the client node would have sent toward the virtual IP address are sent toward the selected server node's IP address instead. Consequently, the IP packets are routed toward the selected server node instead of the load-balancing node.
