Abstract: Embodiments of this application provide a method for obtaining a target transmission route, a related device, and a system. The method is applied to a flexible Ethernet FlexE networking network and includes: receiving a first message that is sent by a second node for requesting to query for a transmission route of a first FlexE client; and sending a second message to the second node, where a route information entry in the second message includes route information of the FlexE client on each node. Ingress information and egress information that are of a FlexE client on a route node are recorded as a transmission route of each hop. A segment-to-segment transmission route in the FlexE network can be dynamically found in real time, a planned and deployed transmission route is compared with an actually found route, to evaluate a network running status.

Abstract: A method includes: receiving a first result obtained by performing BIP check on a sent first to-be-checked bit stream; performing BIP check on a received second to-be-checked bit stream to obtain a second result, where the second to-be-checked bit stream is a bit stream received by a receiving device after the first to-be-checked bit stream is transmitted; detecting a type of a control block in the second to-be-checked bit stream, and determining a third result based on impact of the type of the control block on a BIP check result; comparing the first result, the second result, and the third result; and if the first result is different from the second result, the first result is different from the third result, and the second result is different from a predetermined result, determining that a bit error occurs when the first to-be-checked bit stream is transmitted.

Abstract: The embodiments of the present invention disclose a method, apparatus and system for implementing routing aggregation, which relate to communication field, and solve the problem that too many routings advertised on the DHCPv6 relay agent leads to huge number of routing table entries of the backbone network. The technical solution of the present invention comprises: sending a message to a dynamic host configuration protocol DHCPv6 relay agent, such that the DHCPv6 relay agent generates an aggregation routing of requesting router prefix routings according to the message; wherein the message comprises information about a prefix pool which assigns address prefixes to the requesting routers access to the DHCPv6 relay agent or aggregation routing destination address information generated according to the information about the prefix pool. The method, apparatus and system for implementing routing aggregation may be applied in DHCPv6 network constructions.

Abstract: A frame processing method and apparatus are provided, to implement selective receiving in a redundant transmission scenario. According to a method, a destination device receives a first Ethernet frame from a first intermediate node through a first interface, where the first Ethernet frame includes a first time point, and the first time point is a processing time point of the first Ethernet frame on the first intermediate node. The destination device receives a second Ethernet frame from a second intermediate node through a second interface, where the second Ethernet frame includes a second time point, and the second time point is a processing time point of the second Ethernet frame on the second intermediate node. The destination device determines, based on the first time point and the second time point, whether the second Ethernet frame is a duplicate frame of the first Ethernet frame.

Abstract: A method of data processing is applied to a communications device including a first sublayer. A physical sublayer is added above a physical coding sublayer (PCS) of a physical layer, and the physical sublayer is connected to media independent interfaces (xMIIs) with different Ethernet rates. Data signals from different media access control clients (MAC) are interleaved using the physical sublayer. Then, a tx_cmd command is used to instruct the PCS to correspondingly encode an xMII signal. Finally, an encoded xMII signal is sent through a port. According to this method, an encoding function of the PCS may continue to be used, to decouple interleaving from encoding and perform the interleaving through an xMII interface. In this case, port channelization can be implemented for ports with multiple rates, and transmission of a high-priority service is ensured when there is an excessively large quantity of service flows in a transmission process.

Abstract: Embodiments of the present invention disclose a service multiplexing method. The method includes: sending, by a sending device, a bit block stream of a first service to a receiving device; if the sending device determines to switch from the first service to a second service for service sending, sending, by the sending device, at least one service switching indication bit block to the receiving device; and sending, by the sending device, a bit block stream of the second service to the receiving device. In addition, a service switching indication bit block is inserted between bit block streams that require service switching, to perform service switching, thereby reducing a latency and jitter in a service switching process, and ensuring a low latency during service switching.
