Abstract: Restorable paths in an information network are established in response to arriving traffic requests. Requests are received at a first node of the network for transmission of traffic to a second node of the network, and each request specifies a desired transmission bandwidth for an active and a backup path to be established between the nodes. Potential active links for an active path are identified in response to a given request, and potential backup links to form a backup path for restoring the active path, are also identified in response to the given request. An active and a backup path are then formulated for each given request from among the potential active links and the potential backup links that were identified in response to the given request.

Abstract: Disclosed is a routing apparatus for obtaining routing data conforming to a destination address of a packet that arrives from a line, adding the routing data onto the packet, and switching the packet based upon the routing data to send the packet to a prescribed line. The routing apparatus has a main controller equipped with content addressable memories (CAMs) corresponding to respective ones of line speed. When search key data with an attached line identifier is received from a line card, routing data is generated by the content addressable memory (CAM) corresponding to the line speed and the routing data is sent to the line card. The line card adds routing data of which it has been notified by the main controller onto a packet and then outputs the packet. A switch to which a packet having attached routing data is input from a prescribed line card switches the packet based upon the routing data and sends the packet to another line card.

Abstract: A network interface device connected to a host provides hardware and processing mechanisms for accelerating data transfers between the host and a network. Some data transfers are processed using a dedicated fast-path whereby the protocol stack of the host performs no network layer or transport layer processing. Other data transfers are, however, handled in a slow-path by the host protocol stack. In one embodiment, the host protocol stack has an ISCSI layer, but a response to a solicited ISCSI read request command is nevertheless processed by the network interface device in fast-path. In another embodiment, an initial portion of a response to a solicited command is handled using the dedicated fast-path and then after an error condidtion occurs a subsequent portion of the response is handled using the the slow-path. The interface device uses a command status message to communicate status to the host.

Abstract: A hardware Secure Processing Unit (SPU) is described that can perform both security functions and other information appliance functions using the same set of hardware resources. Because the additional hardware required to support security functions is a relatively small fraction of the overall device hardware, this type of SPU can be competitive with ordinary non-secure CPUs or microcontrollers that perform the same functions. A set of minimal initialization and management hardware and software is added to, e.g., a standard CPU/microcontroller. The additional hardware and/or software creates an SPU environment and performs the functions needed to virtualize the SPU's hardware resources so that they can be shared between security functions and other functions performed by the same CPU.

As registration information from gateways is received, they are associated with the appropriate virtual private network.

Abstract: In a computer network having a plurality of computer nodes, a directory database (DDB) distributed throughout the network in each of the nodes, the contents of the DDB being maintained consistent or replicated throughout the network in a manner to avoid a single point of failure through the use of one of its nodes having been appointed as master node. The master node has a privileged status as compared to the other nodes. The master node updates each DDB in each node in its network or domain configuration when the configuration changes, such as when a node fails, a network link fails and/or a node is added or removed. A node can be added to or removed from the configuration through the master node or through a non master node. A node can fail under different circumstances in which it may or may not know which node is its master node. A master node can fail and be replaced or can be replaced for other reasons.

Abstract: The present invention enables fast reconfiguration of paths associated with bufferless core nodes in a network where any two edge nodes may interconnect through a core node. In order to enhance network agility and performance, edge nodes associated with a core node are separated into a plurality of groups based on, for example, round-trip delay from the core node. This separates the short-haul paths from the long haul paths, thereby enabling the short-haul paths to be configured more frequently than the long-haul paths. It is preferable that the periods be set such that each additional period is an integer multiple of the previous one. This allows for simultaneous configuration of groups of paths. Although the methods and apparatus of the present invention are most effective for bufferless optical switches, they are still effective for electronic switches which may be bufferless or equipped with input data buffers.

The output of the gateway is coupled through a corresponding one of a number of connectors to the end service provider for honoring. The response is transferred from the service provider to the appropriate connector to be formatted for the requesting gateway. The response is converted by the original adapter to an HTML or XML message for transfer back to the requester via the Internet.

Abstract: The present disclosure addresses a system and method for failure tolerant communications using a transmission control protocol, preferably SCTP. In a preferred embodiment, an association is created between two instances of SCTP, where each instance is an endpoint. While an SCTP association provides for multiple IP addresses providing for multiple paths between the instances, it expressly does not provide for failover of the node occupied by the instance itself. The preferred embodiment provides a duplicate instance of SCTP on a separate node in the cluster which provides a hot back-up to the primary instance. The duplicate instance is maintained by replicating the state information for the association to keep the duplicate instance relatively synchronized with the primary instance.
