  • Service chain header and metadata transport
    Patent number: 10637773
    Abstract: Metadata may be embedded in a service chain header (SCH) appended to a packet that is forwarded over a service chain path. The metadata may include information that is used to process the packet at a downstream service function chain (SFC) entity on the service chain path. The metadata TLV field may identify a service action to be performed by a downstream SFC entity. For example, the metadata TLV field may instruct the downstream SFC entity to drop the packet, to redirect the packet (or a traffic flow associated with the packet), to mirror a traffic flow, to terminate a communication connection, to start or stop a packet accounting, and/or to apply a higher grade of service. In another embodiment, the metadata TLV field specifies an OAM service action list that identifies service actions that have been performed on the packet.

  • Method and apparatus for reducing packet retransmission during handover (HO) in low latency mobile communication networks
    Patent number: 10638374
    Abstract: Interruptions in communication due to user equipment (UE) handovers (HO) are signaled from the mobile communication network to the traffic source. For ultra-low latency and reliable communication, the signaling of HO start and completion notifications prevents retransmissions of in-flight packets by the traffic source, eliminating additional delays and inefficiencies. Signaling can be implemented by a network element, by a network element in conjunction with a smart traffic handler between the network and the traffic source (e.g., applications) and by a UE having at least two different radio interfaces.

    Abstract: A network element (NE) in a zone routing network includes a memory, receiver, processor, and transmitter. The memory stores a routing information base (RIB) identifying a first next-hop node for a first path in the network to reach a network controller of the network via a first communication node in the network. The first communication node is directly associated with the network controller. The receiver receives a first label-switched path (LSP) creation request message requesting creation of a first LSP through the network. The first LSP creation request message indicates an ingress node of the first LSP. The processor determines that the NE corresponds to the ingress node of the first LSP. The transmitter sends a first LSP creation response message towards the network controller via the first communication node according to the first path to indicate a creation status of the first LSP.
