摘要： In one embodiment a limited functionality link state protocol node has one or two interfaces configured to send and receive link state protocol packets. In response to receiving, by the partially-participating link state protocol node on a first interface, a particular link state protocol data unit (LSP): sending the particular LSP from a second interface of the partially-participating link state protocol node without updating the local link state database when the second interface is currently participating in the link state protocol distribution; and sending an acknowledgment of the particular LSP from the first interface when the second interface is not currently participating in the link state protocol distribution.

摘要： One embodiment includes: forwarding a particular packet through an Available Routing Construct (ARC) chain topology network. In one embodiment, this forwarding includes: sending the particular packet by each particular non-edge node on an arc of the plurality of arcs receiving the particular packet to each sibling on the arc that did not send the particular packet to said particular non-edge node, while not sending the particular packet if it was received from both siblings of said particular edge node; and sending the particular packet to a respective child node on a second arc of the plurality of arcs by each particular edge node of two edge nodes on the arc after receiving the particular packet. In one embodiment, the network is a wireless deterministic network with pre-assigned time slots for receiving and subsequently sending a same particular packet by each node of the network.

摘要： A process for the reliable distribution of a shortcut table for layer 3 switching is distributed from a plurality of routers to a plurality of switches includes the transmission by the router of a list of shortcut entries, which includes a list of switches which have acknowledged receipt of this list of shortcut entries. The transmission of these database messages continues until all target switches have acknowledged receipt of the database messages. The interval between transmission of database messages is short until all switches have acknowledged reception of such database messages, and thereafter the interval between transmissions is lengthened, and a hello message is sent until a new switch is added to the network, or a change in router shortcut database occurs, whereafter the transmission of database messages is resumed utilizing the interval between these transmissions is again shortened until all such messages have been acknowledged.

摘要： Ethernet Alarm Indication Signal (ETH-AIS) information for multiple Virtual Local Area Networks (VLANs) is consolidated and distributed to the multiple VLANs in a single Ethernet frame. Note, as used herein, “Alarm Indication Signal (ETH-AIS)” refers to an IEEE 802.x or ITU-T Y.1731 Ethernet Alarm Indication Signal. A device receiving the Ethernet frame with the consolidated ETH-AIS information typically forwards the frame out each port that communicates traffic for one of the VLANs included in the consolidated ETH-AIS information.

摘要： A solution is provided wherein physical link parameters may be negotiated after a link is brought up by having the two devices involved in the link exchange identifiers when the link is initially brought up. These identifiers may be saved in the devices and then utilized upon receipt of subsequent physical link parameter negotiation packets to ensure that these packets are received by a partner who is connected via a physical link.

摘要： An endpoint for determining a frame loss ratio is provided. The endpoint includes a processor and a memory coupled with the processor. The memory stores instructions that are executable to generate a number of synthetic frames, and insert the number of synthetic frames into a stream of data frames, the synthetic frames being transmitted to a responder endpoint address designated in the synthetic frames. The memory may also store instructions that are executable to determine a number of lost synthetic frames; and calculate a synthetic frame loss ratio as a function of the number of lost synthetic frames and the number of synthetic frames inserted into the stream of data frames.
