    摘要： A dedicated control path architecture for systems of devices, such as stacking systems, is provided. In one embodiment, a network device for use in a system of devices can comprise a CPU complex; a first set of ports for establishing a data path between the network device and other network devices in the system of devices; and a second set of ports for establishing a control path between the network device and the other network devices in the system of devices. The control path can be separate from the data path and can allow the CPU complex to exchange control plane traffic with other CPU complexes resident in the other network devices.

    摘要： A failure at a first port of the controller node is detected, where the first port is initially assigned a first port identifier and is associated with a logical path through a communications fabric between the first port and a port at a host device. In response to detecting the failure, the first port identifier is assigned to a second port to cause the logical path to be associated with the second port. In response to detecting resolution of the failure, a probe identifier is assigned to the first port. Using the probe identifier, a health of network infrastructure between the first port and the host device is checked. In response to the checking, the first port identifier is assigned to the first port to cause failback of the logical path to the first port.

    摘要： Accordingly, there is provided an IMS node, comprising a transmission module and a processor. The transmission module is arranged to send SIP messages to a plurality of other IMS nodes. The processor arranged to detect an error in a particular other IMS node, the error indicating that the particular other IMS node is not available to receive traffic. In response to detection of such an error, the processor causes the particular other IMS node not to be used for a period of time. The transmission module is further arranged to send at least one test message to the particular other IMS node when the period of time expires. The processor is further arranged to determine if the at least one test message is successfully processed by the particular other IMS node, and in response to a positive determination then returning the particular other IMS node to use.

    摘要： In an open flow system, it is made possible to confirm a flow having succeeded or failed in the registration on a flow table. Specifically, a controller transmits and receives an open flow message to and from a switch. The switch is provided with a flow table which manages flows registered from a controller, and a flow table reading section which reads corresponding data, a flow table control section which performs processing of addition, deletion and modification of a flow entry, and a platform function managing section which determine whether an object flow entry is valid or invalid according to an inquiry from the flow table control section. The flow table has a normal flow table and a save flow table. A valid flow entry which conforms to configuration data of the switch is registered on the normal flow table. An invalid flow entry which does not conform to the configuration data of the switch is registered on the save flow table.

    摘要： An example network system includes a layer two (L2) device and a layer three (L3) device. The L2 device includes a control unit is configured to determine a preferred network path from a first L2 network in which the L2 device resides to an intermediate L3 network in which the L3 device resides that couples the first L2 network to a second L2 network having a second L2 device. The control unit includes a management endpoint (MEP) module. The MEP module executes an operations, administration, and management (OAM) protocol to monitor the first L2 network and output an L2 frame in accordance with the OAM protocol to the L3 device to notify the L3 device that it is within the preferred network path. A MEP module of the L3 device executes an OAM protocol that outputs L2 frames to the L2 device indicating the status of the L3 network.
