摘要： In one embodiment, a method for facilitating centralized issue tracking. The method includes receiving information on a case from an issue tracking system (case information). The method facilitates executing a tagging method stored in a memory device that reads the case information, determines whether a part of the case information is desired information, and then tags the desired information. Finally, the method facilitates communicating the tagged information to a centralized database, where the centralized database stores the tagged information, and where the tagged information is accessible to the issue tracking system and at least one other issue tracking system.

摘要： In one embodiment, an initiating maintenance end point (MEP) may transmit a lock message to lock a circuit traversing one or more maintenance intermediate points (MIPs) between the initiating MEP and an end MEP. The initiating MEP may then transmit an in-band packet containing a loopback request to a particular MIP along the circuit using a particular time-to-live (TTL) value in the packet to reach the particular MIP. Upon receiving the packet at the particular MIP, and in response to determining that the TTL has expired, the particular MIP inspects the packet to discover the loopback request, and correspondingly operates in a loopback mode.

摘要： A system and method for providing link, node, and PG policy based routing in PNNI based ATM networks is disclosed. A computer implemented method signals and routes a call in the network. Upon detecting the call's arrival, its service request is accessed. Upon determining that the service request relates to an attribute of a link, a routing path is sought that conforms to the service request, as by accessing information relating to the routing path and comparing the information to the service request. A conforming routing path is selected, and the call is routed via that path. A computer implemented method advertises an attribute of links, nodes, policies, etc. Data relating to the route's attribute can be provided to a node as a GAT IE component of a PNNI signaling setup message for multi-peer group networks, and advertised using PTSEs within a peer group.

摘要： An application node advertises service(s), using a routing protocol, that it offers to other network nodes. For example, the routing protocol used to advertise service(s) in a Service Provider Network is typically an link-state, Interior Gateway Protocol (IGP), such as, but not limited to, Intermediate System to Intermediate System (IS-IS) or Open Shortest Path First (OSPF). Packets are encapsulated and sent from a service node (e.g., packet switching device) using one or more advertised services applied to a packet by an application node (e.g., a packet switching device and/or computing platform such as a Cisco ASR 1000).

摘要： Packet meta-tagging using excess payload is described. In an implementation, a total packet length value specified in packet received at a network element is adjusted while preserving a data length value associated with a data portion of the packet to generate additional space in the packet to accommodate packet transmission meta-data. Packet-transmission meta-data can be inserted into the additional space created in the packet by the network element. In some implementations, the meta-data describes packet transmission characteristics of the packet. For example, the meta-data can be a timestamp corresponding to the time at which the packet was received by the network element. The meta-data can be an identifier corresponding to the network element that received the packet.
