Method and device for managing Ethernet topology

Abstract

The invention discloses a method for managing Ethernet topology, comprising the following steps of: setting an Ethernet topology managing domain, wherein each node in the managing domain transmits a protocol frame comprising self mark information and state information according to a transmitting strategy; and determining and storing the Ethernet topology relation of the managing domain according to the mark information and state information of the nodes in the protocol frame by a node receiving the protocol frame. The invention discloses a device for managing Ethernet topology, comprising a setting unit, a transmitting unit, a receiving unit, a determining unit and a storing unit, wherein the setting unit is used for setting the Ethernet topology managing domain; the transmitting unit is used for transmitting the protocol frame comprising the self mark information and the state information according to the transmitting strategy; the receiving unit is used for receiving the protocol frame; the determining unit is used for determining the Ethernet topology relation of the managing domain according to the mark information and state information of the nodes in the protocol frame, and the storing unit is used for storing the Ethernet topology relation of the determined managing domain of the determining unit. By the invention, all the nodes in the managing domain can accurately know the topology relation of the managing domain in time.

Description

technical field [0001] The invention relates to the technology of Ethernet topology management, in particular to a method and device for Ethernet topology management. Background technique [0002] With the development of the Ethernet network in the direction of multi-service bearing, especially some services have higher and higher requirements on the reliability and real-time performance of the network, the Ethernet widely adopts the redundant networking mode to improve the network reliability. In addition, in the redundant networking structure of the Ethernet, fast protection switching is usually required (the duration of the protection switching is required to be within 50 ms). Currently, technologies related to fast protection switching include standards such as RFC3619 of the Internet Engineering Task Force (IETF, Internet Engineering Task Force) and G.8032 of the International Telecommunication Union (ITU-T, International Telecommunication Union). [0003] For example,...

Problems solved by technology

[0006] In the above-mentioned networking structures of the Ethernet ring network, because one or some ports in the network are usually blocked, the transmission path of the traffic is not completely consistent with the physical topology of the network, and with the protection switching, the transmission path of the traffic is still Changes will occur. In actual operation, there needs to be a method that can manage the Ethernet topology, which can intuitively and conveniently discover information such as node locations, topology status, path reachability, and protection protocols in the overall network.

However, there is currently no technical solution to specifically determine the Ethernet topology relationship and manage the topology relationship
