Abstract: Systems and methods for arbitrating among traffic from a coherence point to a switch fabric. A multi-level arbiter is used to avoid starvation while providing fairness and high bandwidth on the connection path between the coherence point and the switch fabric. A first level of arbitration selects packets with enough available credits for forwarding from the switch fabric on a downstream channel. The second level of arbitration arbitrates among short packets at a first arbiter and arbitrates among long packets at a second arbiter. The selected short packet and the selected long packet are forwarded to a third level of arbitration. The third level of arbitration alternates between long and short packets and forwards the selected packet to the switch fabric.

Abstract: A cluster compute server includes nodes coupled in a network topology via a fabric that source routes packets based on location identifiers assigned to the nodes, the location identifiers representing the locations in the network topology. Host interfaces at the nodes may be associated with link layer addresses that do not reflect the location identifier associated with the nodes. The nodes therefore implement locally cached link layer address translations that map link layer addresses to corresponding location identifiers in the network topology. In response to originating a packet directed to one of these host interfaces, the node accesses the local translation cache to obtain a link layer address translation for a destination link layer address of the packet. When a node experiences a cache miss, the node queries a management node to obtain the specified link layer address translation from a master translation table maintained by the management node.

Abstract: A method and system for provisioning circuits on multiple parallel links with a single setup message is disclosed. A setup message specifying links in a circuit path is transmitted to switches along the circuit path. If a switch determines that a link specified in the setup message has insufficient bandwidth for the circuit, the switch substitutes a parallel link having sufficient bandwidth for the specified link in the circuit path. The setup message can indicate whether substitution for a link is permitted. This can be used to prevent substitution for links when provisioning service routes for new circuits in order to maintain diversity requirements, while allowing substitution for links when provisioning restoration routes for failed circuits in order to reduce restoration time.

Abstract: The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

Abstract: Application MGIDs defining virtual groups of output destinations are assigned by applications and appended to packets to specify on a per-application basis how packets associated with the application should be handed by a network element. The application MGIDs are mapped to single system MGID number space prior to being passed to the network element switch fabric. When a packet is passed to the switch fabric, the application MGID header is passed along with the system MGID header, so that the packet that is passed to the switch fabric has both the system MGID as well as the application MGID. The switch fabric only looks at the system MGID when forwarding the packet, however. Each egress node maintains a set of tables, one table for each application, in which the node maintains a list of ports per application MGID. The egress node uses the application MGID to key into the application table to determine a list of ports, at that egress node, to receive the packet.

The master and slave device may determine respective time values corresponding to the respective counter values based on in-switch delays of the packets.

The TempENUM database stores a TempENUM from a coordinator system and relates the actual calling party identifier (CgPID) for use in callback attempts. Either during the initial call or communication, or shortly thereafter, the receiving party uses the TempENUM number to return communication the initial caller.
