This application provides a method and apparatus for smoothing port failures. The method includes receiving a link state interruption event; reading the link state register of the physical layer chip that generated the link state interruption event; reading the fault type and the physical port where the link interruption occurred from the link state register; determining the fault type as a local link interruption, setting the logical operating state of the physical port to "off", clearing all Layer 2 MAC forwarding table entries with the physical port as the outgoing port, and updating the Layer 3 forwarding information base (FIB) table entry of the Layer 3 interface to which the physical port belongs; or, determining the fault type as a remote link interruption, recording at least the physical layer chip, the physical port, and its current detection count, and starting a software delay timer. This application is applicable to various IP networks and FTTR networks.

Some disclosed examples involve receiving information regarding a forwarding information base (FIB) sequence number, placing the FIB sequence number into a FIB sequence number queue and assigning the FIB sequence number a first state. Some examples involve receiving a route processing request including an indication of a route and a platform sequence number associated with the FIB sequence number, assigning the FIB sequence number a second state and placing the route processing request into a route-associated queue corresponding to the route. Some examples involve receiving a route processing response corresponding to the route and corresponding to one or more route processing requests, including the route processing request, removing the route processing request from the route-associated queue, assigning the FIB sequence number a third state and publishing the FIB sequence number.

The invention provides a segment routing policy intermediate node protection method, which is applied to a first node, and comprises the following steps: receiving a data message, an outer layer destination address of the data message being a segment identifier; querying a forwarding information base, and obtaining a routing table item corresponding to the segment identifier; querying a port state table according to the identification information of the physical port in the routing table entry to obtain the real-time state of the physical port; wherein the port state table is used for associatively storing identification information and state information of the physical port, and the state information of the physical port is independently maintained and updated in real time by a port management module of the first node based on a physical layer event; in response to the fact that the real-time state of the physical port is unavailable and the second node corresponding to the segment identifier is an intermediate node, the data message is forwarded to the third node corresponding to the next segment identifier in the segment route header of the data message, and a route convergence process with long time consumption does not need to be waited. The data message can be forwarded to the third node by directly bypassing the second node, so that the forwarding efficiency is improved.

A method for processing packets, the method comprising receiving a packet by a data processing unit (DPU), making a first determination that there is no exact match flow entry in a hardware switch pipeline in the DPU for the packet, in response to the first determination, classifying, in the DPU, the packet as a data packet, in response to the classifying of the packet: identifying, using a software data plane in the DPU, a forwarding information base (FIB) entry to be used to transmit the packet towards its intended destination, identifying, using the software data plane, a flow associated with the packet, initiating, using the software data plane, programming of an exact match flow entry in the hardware switch pipeline, and initiating, using the software data plane, transmission of the packet towards its intended destination using the FIB entry and the hardware switch pipeline.

A network element includes processing circuitry configured to cause the network element to determine whether a received information packet is a special packet based on whether a domain header of the received information packet includes a domain configuration group (DCG) address for a domain type of the network element in a destination address field of the domain header, the DCG address being indicative of an add command or a delete command, extract an identifier of a network domain from the domain header of the received information packet in response to determining that the received information packet is a special packet, and modify a forward information base at the network element based on the DCG address and the identifier of the network.
