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.
摘要翻译：在一个实施例中，启动维护端点（MEP）可以发送锁定消息以锁定经过起始MEP和结束MEP之间的一个或多个维护中间点（MIP）的电路。然后，启动MEP可以使用分组中的特定生存时间（TTL）值将包含环回请求的带内分组沿着电路发送到特定的MIP，以达到特定的MIP。在接收到特定MIP的分组时，响应于确定TTL已经到期，特定MIP检查分组以发现环回请求，并相应地以环回模式工作。

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.
