Problems solved by technology

However, this proprietary approach is often limited to specific vendor
[0006] Clearly, manual updates of topology-aware entities / systems associated with Ethernet networks are error-prone and time-consuming, and are particularly difficult during large network rollouts

Embodiment Construction

[0030] The description begins with an introduction to the standards for Operations, Administration and Manipulation (OAM) in Ethernet networks. Then, based on the standardized mechanism IEEE802.lag, an example embodiment for automatic and scalable topological location discovery of new nodes / network devices joining an existing Ethernet network is presented. Throughout the description, the same reference numerals are used to identify corresponding elements.

[0031] To adapt Ethernet technology in a carrier-class service environment, multiple standards have been developed and are being developed to provide advanced OAM capabilities (also known as Ethernet Connectivity and Fault Management or Ethernet Net CFM). Since an end-to-end service network environment typically consists of a patchwork of various branch networks (for example, metro access and core networks using multiple technologies) that may belong to different organizations, network operators, and service providers, Eth...

Abstract

A topology aware entity, such as an OSS (Operations Support System), an NMS (Network Management System) or an RM (Resource Manager), associated with an Ethernet network is configured to execute a method for topological location discovery of nodes that are added to the network. According to the method, the topology aware entity receives (step 30) a notification about a new node that has been added to the network. Then, the topology aware entity causes (step 31) an existing node to initiate a path discovery to the new node using an Ethernet Connectivity and Fault Management, CFM, protocol, such as IEE 802.1 ag or ITU-T Y.1731. The topology aware entity receives (step 32) the resulting path data from the existing node and identifies (step 33), based on the path data, a topological position of the new node in the Ethernet network. The method may be embodied as program instructions stored on a computer-readable medium.

Description

technical field [0001] The present invention generally relates to the discovery, configuration and provisioning of network devices in Ethernet networks. More specifically (but not by way of limitation), the present invention is directed to a technique for automatic topological location discovery of network devices joining an Ethernet network. Background technique [0002] Ethernet is a widely used family of frame-based computer networking technologies for local area networks (LANs). It defines multiple cabling and signaling standards for the physical layer of the OSI networking model, relying on network access and common addressing formats at the Media Access Control (MAC) layer / data link layer. Ethernet is standardized by the organization IEEE, currently under IEEE802. [0003] Ethernet-based networks expand beyond traditional geographic boundaries, and the number of users grows rapidly. Consequently, there has also been a significant increase in the number of network de...
