Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 It is a schematic diagram of the structure of the DPOE system provided by the present invention. The DPOE system generally refers to the EPON system that conforms to the DOCSIS Service Interface Specification (DOCSIS), which is proposed by several companies and promoted by CableLabs. A passive optical network system based on the Ethernet-based passive optical network (EPON, GEPONor10GigEPON) based on the media access control MAC layer and physical PHY layer standards to implement the DOCSIS service layer interface. The DPOE system includes a background management system composed of similar TFTP servers, a DPOE central office system, optical fiber subscriber units ONU1...ONUn, and user equipment connected to the aforementioned ONUs.

[0021] The DPOE system maintains the existing DOCSIS-based operation and management platf...

Abstract

The invention provides a VPLS (Virtual Private LAN Service) implementation method based on a wired DOCSIS (Data Over Cable System Interface Specification), and a communication device. Through obtaining a cable modem configuration file which comprises VPLS signal parameter coding information for building a two-layer private network, the method can define the VPLS signal parameter coding information for identification through one TLV (type length value) packaged through an NSI (network system interface). The TLV can further comprises a plurality of SubTLVs (sub-type length values) which are respectively used for identifying specific VPLS signal parameter items, such as an AGI (access circuit identification), an opposite end IP address list of a net pseudo-wire, a pseudo-wire type, and a control character. Therefore, a service provider edge router PE can build and maintain the PW (pseudo-wire) along with other PEs in the network according to the VPLS signal parameter coding information.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a virtual local area network service realization method and device based on the DOCSIS cable data service interface specification. Background technique [0002] Network traffic based on packet switching is growing exponentially, most of which are based on Ethernet or IP. The rapid growth of metro Ethernet services in the enterprise market is mainly due to the familiarity of enterprise users with Ethernet and the impact of Ethernet on Support for various existing devices. At the same time, the enterprise-level market is also integrating IP telephony and data networks, using QoS-based metropolitan Ethernet as an access method. [0003] Because of the increasing demand for Metro Ethernet, telecom operators have begun to consider how to provide carrier-class Ethernet services based on various network forms. Among them, the cable data service interface specification DOCSIS is a...
