20190356511 · 2019-11-21 ·

Embodiments of the present disclosure provide a method and an apparatus for processing service data. The method includes: receiving an uplink service flow, wherein the uplink service flow includes a first tunnel identifier and a destination address; determining a first tunnel mapping table corresponding to the first tunnel identifier, wherein the first tunnel mapping table includes the first tunnel identifier, one or more second tunnel identifiers corresponding to the first tunnel identifier, and one or more service addresses corresponding to each of the second tunnel identifiers; searching a service address the same as the destination address from the first tunnel mapping table; determining the second tunnel identifier of the uplink service flow based on the destination address if the searching is failed; and transmitting the uplink service flow to a service anchor corresponding to the second tunnel identifier of the uplink service flow.

Apparatus, system, and method for providing node protection across label-switched paths that share labels

The disclosed computer-implemented method may include (1) receiving, at a network node within a network, a packet from another network node within the network, (2) identifying, within the packet, a label stack that includes a plurality of labels that collectively represent at least a portion of a label-switched path within the network, (3) popping, from the label stack, a label that corresponds to a next hop of the network node, (4) determining, based at least in part on the label, that the next hop has experienced a failure that prevents the packet from reaching a destination via the next hop, (5) identifying a backup path that merges with the label-switched path at a next-to-next hop included in the label-switched path, and then (6) forwarding the packet to the next-to-next hop via the backup path. Various other methods, systems, and apparatuses are also disclosed.

Label switched path node failure management for label switched paths having refresh interval independent fast reroute facility protection

In one example, techniques of this disclosure may enable a point of local repair (PLR) network device to signal availability of link protection or node protection to a merge point (MP) network device and enable a network device to actively determine whether or not it is a merge point router. Based on whether or not the network device determines it is a MP, the network device may selectively clean up LSP states when there is an upstream link or node failure. The RSVP-TE protocol may be extended to enable a network device to send a tear down message to a downstream router, which may enable the downstream router to conditionally delete locale LSP state information. In some instances, a PLR network device may directly send a tear down message to a MP network device even though the PLR network device may not have a working bypass LSP.

BACKPRESSURE SIGNALING FOR WIRELESS COMMUNICATIONS

Methods, systems, and devices for wireless communications are described. In some wireless systems, a base station centralized unit (CU) may communicate with a user equipment (UE) through a multi-hop backhaul architecture. This multi-hop backhaul connection may include a donor base station and any number of relay base stations connected via backhaul links. In some cases, the relay base stations or the UE may experience data congestion in a logical channel-specific buffer. The relay base stations or UE may implement backpressure signaling (e.g., in the medium access control (MAC) layer) to mitigate the congestion. A wireless device operating as a mobile termination (MT) endpoint may transmit a backpressure report message to a wireless device operating as a base station distributed unit (DU) endpoint for the logical channel. The base station DU may adjust a scheduling rate for data unit transmissions over the indicated logical channel based on the backpressure report.

Methods and systems for network connectivity
10425304 · 2019-09-24 · ·

Methods and systems are provided for connecting an electronic device to a network. In some situations, the electronic device connects to a first network provider and pings a first server having a static internet protocol address and a second server having a dedicated uniform resource locator. If the electronic device receives a response from the first and second server, the electronic device maintains its connection to the first network provider. Otherwise, the electronic device connects to a second network provider and pings the first and second servers.

Method of communications in a network interconnecting at least two power generators, and corresponding interfacing device

A method is provided for communications in a network interconnecting at least two power generators, each power generator being connected to said network by at least one interfacing device capable of sending and receiving communications frames. The frames have at least one piece of supervision data and at least one piece of information data. The method includes an act of sending during which the same pieces of information data are sent at least twice, wherein two operations of sending frames have identical pieces of information data being separated in time by a predetermined time interval; and an act of receiving, implementing a systematic elimination of one of the frames received when two frames having identical pieces of information data have been received.

TUNNEL PROVISIONING WITH LINK AGGREGATION
20190222512 · 2019-07-18 ·

A method for processing data packets in a communication network includes establishing a path for a flow of the data packets through the communication network. At a node along the path having a plurality of aggregated ports, a port is selected from among the plurality to serve as part of the path. A label is chosen responsively to the selected port. The label is attached to the data packets in the flow at a point on the path upstream from the node. Upon receiving the data packets at the node, the data packets are switched through the selected port responsively to the label.

Methods and systems for fast switching between bi-directional co-shared sessions having different network paths over a resource reservation network. Embodiment of one method includes: creating a bi-directional parent session (S.sub.p) between first and second session partners, creating a bi-directional derivative session (S.sub.d) between the first session partner and a third session partner, and reassigning a predetermined amount of co-shared network resources (PA-CSNR) assigned to the S.sub.p using the following steps: (i) sending a first message to request the second session partner to stop using the PA-CSNR, (ii) sending a second message to register whether the PA-CSNR are assigned to the S.sub.d, and (iii) sending a third message to allow the third session partner to utilize at least some of the PA-CSNR for the S.sub.d.

Bi-directional co-shared sessions
10218636 · 2019-02-26 · ·

Methods and systems for a resource reservation network that supports bi-directional co-shared sessions. A session creation module (SCM) creates a bi-directional parent session (S.sub.p), between first and second session partners, by: allocating co-shared network resources over a first network hop, and allocating network resources over a second network hop. The SCM further creates a bi-directional derivative session (S.sub.d) between the first session partner and a third session partner, by: allocating network resources to the S.sub.d over a third network hop, and not allocating specifically for the S.sub.d all the network resources required for the S.sub.d over the first network hop.
