摘要： A transmission system according to the present invention includes a transmission device and a reception device connected with each other via two lines. When the transmission device switches a line; used for transmitting VLAN traffic, from a first line to a second line, the transmission device transmits the VLAN traffic to the second line by switching the line after transmitting a post-switching message to the first line. The reception device includes a first buffer which stores the VLAN traffic received from the first line and a second buffer which stores the VLAN traffic received from the second line. When the reception device receives the post-switching message from the first line, the reception device starts reading of the VLAN traffic from the second buffer after reading the entire VLAN traffic stored in the first buffer.

摘要： Data communications are effected over one or more network branches to ensure appropriate receipt of data at different devices on the network. In accordance with an example embodiment, time-based communications are effected for a plurality of different network devices, at least two of which are connected to a common wired network link, with each network device being assigned to communicate during different time slots within a communication cycle. Each communication received on the common wired network link is assessed as being error-indicative or not error-indicative. In response to a received communication on the common wired network link being assessed as being error-indicative, the common wired network link is operated to corrupt data received on the branch, such as by driving the branch during a time slot in which the error-indicative communication is received, therein ensuring that other network devices disregard the data received during that time slot.

摘要： A method is presented for supporting SNCP over a packet network connecting to two SDH sub-networks and transporting one or more SDH paths that are SNCP-protected in both SDH sub-networks. The packet network connects to each of two sub-network interconnection points by a working path and a protection path. The packet sub-network may provide the same type of path protection as an SDH sub-network using SNCP, while avoiding bandwidth duplication.

摘要： One embodiment provides a system that facilitates processing of error-condition information associated with a content-centric network (CCN) message transmitted over a network. During operation, the system receives, by a first node, a packet that corresponds to a CCN message, where a name for the CCN message is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. Responsive to determining that the CCN message triggers an error condition, the system generates an interest return message by pre-pending a data structure to the CCN message, where the data structure indicates the error condition. The system transmits the interest return message to a second node.

摘要： Systems and methods are disclosed for effectuating control-plane changes at increased speeds to protect a network in which switching operations are performed. Operations to effectuate control-plane changes in the network can be divided between software and more-rapid, dedicated hardware within a line card. Examples of operations reserved to hardware implementation can include blocking and unblocking of ports, flushing of learned entries from switch tables, and coordination of control-plane changes through the generation of messages sent between nodes, and also between line cards of a node. Determinations about the need for hardware-driven, control-plane changes may be made based on events occurring in the network in accordance with any of a number of different network protection protocols. The protocol may be implemented in a state machine and the software may determine the state of the hardware through a master/slave relationship.

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.
