  • Patent number: 10972377
    Abstract: In one embodiment, network nodes coordinate recording of In-Situ Operations, Administration, and Maintenance (IOAM) data in packets traversing the network nodes, including a node adding IOAM data of another node to packets on behalf of the another node. After receiving a particular packet, a network node adds first IOAM data and second IOAM data to the particular packet, with the first IOAM data related to the first network node and the second IOAM data related to a second network node. The packet is then sent from the first network node. The coordinated offloading of the adding of IOAM data to packets allows a node to free up resources currently used for IOAM operations to be used for other packet processing operations, while still having IOAM data related to the node recorded in packets. The coordinated offloading may include control plane communication (e.g., via a routing or other protocol).

  • Patent number: 9774494
    Abstract: Embodiments of the present invention disclose a method, apparatus, and system for detecting performance of a layer 3 virtual private network. A first node creates an OAM instance according to OAM configuration information set by a user, and sends the OAM configuration information to a second nodet; the second node creates an OAM instance according to the OAM configuration information; and the first node performs OAM detection by sending an OAM packet to the second node and/or receiving an OAM packet from the second node, where the sending and/or receiving is implemented by using the OAM instance of the first node. According to the present invention, not only an OAM configuration procedure is simplified and manpower is saved, but also consistency of OAM configuration at two ends can be ensured. In addition, a configuration delay in this dynamic configuration manner may be ignored.

  • Patent number: 9686199
    Abstract: A method for implementing Ethernet operation, administration, and management (OAM) function in a network element coupled to a software-defined networking (SDN) system is disclosed. The method comprises adding a flow table entry for an OAM traffic flow to a flow table of the network element. The method continues with adding a group table entry for the OAM traffic flow to a group table of the network element, where the group table entry includes an instruction to send the packet to a set of ports, including a loopback port. The method continues with receiving the packet directing to the group table entry from the SDN controller, and sending the packet to the set of ports of the network element according to the group table entry, where the packet is to be looped back through the loopback port to the flow table periodically at a predetermined interval.

  • Patent number: 9535760
    Abstract: Improving the performance of multitasking processors are provided. For example, a subset of M processors within a system with N processors is dedicated for a desired task. The M (where M>0) of the N processors are dedicate to a task, thus, leaving N?M (N minus M) processors for running normal operating system (OS). The processors dedicated to the task may have their interrupt mechanism disabled to avoid interrupt handler switching overhead. Therefore, these processors run in an independent context and can communicate with the normal OS and cooperation with the normal OS to achieve higher performance.
