Problems solved by technology

[0039] The technical problem to be solved by the present invention is to provide a method and system for managing service levels in Metro Ethernet, to overcome the problem that UNI-C can only obtain the bandwidth policy corresponding to the current service level and cannot actively request UNI-N to change the current service level in real time , you can ask UNI-N to change the service level at any time to improve system performance

specific Embodiment

[0092] Hereinafter, the present invention will be described in detail by taking an enterprise building connected to the Internet (Internet) through a metropolitan Ethernet as an example, in conjunction with the accompanying drawings.

[0093] In an application where an enterprise building accesses the Internet through a MAN, the CE device located in the enterprise building is generally a user gateway router, and the PE device located at the carrier's office end of the MAN Ethernet is generally a network edge router. The port connected to the edge router is UNI-C, and the port connected to the user gateway router on the network edge router is UNI-N.

[0094] image 3 It is a flow chart of the realization method of obtaining and changing the service level in real time in the specific embodiment. In this embodiment, the content and process of signaling interaction between UNI-C and UNI-N not only conform to the regulations of E-LMI technology, but also increase the new interacti...

Abstract

The present invention discloses a method for service level management in the Metro Ethernet and system thereof, and the method mainly includes: a provider edge device provides all available service levels and corresponding bandwidth strategies to a Customer Edge (CE) device; the customer edge device sends to the provider edge device a status alternation request message in which an expected service level is carried, or in which both a current service level and the expected service level are carried simultaneously; the provider edge device returns a status alternation reply message in which an instruction for agreeing or refusing the alternation is carried. The present invention enables the CE device to obtain and alternate the service level in real-time in the Metro Ethernet, and the problem is overcame that the User Network Interface-Customer (UNI-C) can only obtain the bandwidth strategy corresponding to the current service level and can not actively request the User Network Interface-Network (UNI-N) to alternate the current service level in real-time, thus the UNI-N can be requested to alternate the service level at any time, and the system performance is improved.

Description

technical field [0001] The invention relates to the field of Ethernet business service level in the field of data communication, in particular to a method and system for managing service level in the metropolitan area Ethernet. Background technique [0002] With the continuous development of Ethernet technology, the network capacity of Ethernet continues to increase, from the traditional 10 / 100Mbps to 1Gbps, 10Gbps, Ethernet with a higher transmission rate of 40Gbps and 100Gbps has also appeared; at the same time, the transmission of Ethernet The distance is also increasing, from the traditional 100M to 2KM, 10KM, and Ethernet that supports 80KM or even longer transmission distances has also appeared. The application of Ethernet has become more and more extensive due to the development of technology. In addition to continuing to occupy an absolute monopoly position in LANs, Ethernet has already been widely used in metropolitan area networks and even wider wide area networks....
