Embodiment Construction

[0015] The present invention will be further elaborated below according to the drawings and specific embodiments.

[0016] A star network system of the present invention comprises Ethernet (LAN), CE1 star network (belonging to wide area network WAN), and router 11 with channelized CE1 and time slot crossover connecting Ethernet and CE1 star network Device 12. Wherein, the time slot crossover 12 is respectively connected to the CE1 bridge 14 and the router 11 in the CE1 star network. The router 11 is also connected to network nodes 13 such as an Ethernet switch, a data server, a video server, a video browser, or a data browser in the Ethernet. The CE1 bridge 14 has a switching function, and can bidirectionally forward the data flow of the Ethernet port and the CE1 port (ie WAN). All collectors 15 and intelligent devices 16 connected under the CE1 bridge 14 of CE1 star network are all IP (Internet Protocol, Internet Protocol) equipment, like this, by the router 11 of Ethernet,...

Abstract

The present invention relates to the all-IP network technology, in particular to a LAN-WAN-LAN star-shaped network that utilizes the existing E1 channel star-shaped network resources that can be divided into time slots to realize a smooth transition from the existing network to the all-IP transmission stage methods and systems. A star networking method, comprising the following steps: A1. crossing the E1 channels of N roads that can divide time slots into one CE1 in the E1 channel star network that can be divided into time slots; A2. utilizing virtual Ethernet bridging technology to After aggregation, one E1 channel that can be divided into time slots is mapped to N virtual Ethernet interfaces, which are connected to the Ethernet. The invention also discloses a star network system. The invention connects the time-slottable E1 channel star network and the Ethernet through the time slot crossover device and the channelized router, so that the whole network can be regarded as a transparently transmitted star network. Without changing the existing infrastructure, the smooth transition of all-IP transmission is realized with the minimum cost.

Description

technical field [0001] The present invention relates to the all-IP network technology, in particular to a LAN-WAN-LAN star-shaped networking method and system for realizing smooth transition from the existing network to the all-IP transmission stage by utilizing existing CE1 star-shaped network resources. Background technique [0002] The monitoring data transmission equipment is a part of the power environment monitoring system of the computer room. Such equipment in the prior art is mainly connected to the front-end computer through appropriate transmission resources through serial ports such as RS422 bus. The main disadvantages of the existing monitoring data transmission equipment are as follows: 1. The data communication bandwidth is not high; 2. It is not convenient for network management and maintenance. [0003] The all-IP system can effectively overcome the above shortcomings. The all-IP system structure is the industry's view on the future network. The future netwo...
