Embodiment Construction

[0033] The reference model of PWE3 service is as follows: figure 1 As shown, the PE1 and PE2 are operator edge devices, CE1 and CE2 are user edge devices, and one or more PWs are established between PE1 and PE2, that is, the PWE3 channel, and the access link is between CE and PE. The access link may be an Ethernet or a non-Ethernet such as a TDM network. After CE1 and CE2 are respectively connected to PE1 and PE2, the communication between CE1 and CE2 is realized through the PW, and the PW is carried on the PSN tunnel. The PSN tunnel determines the data forwarding path. When CE1 and CE2 communicate, after the user data of CE1 is transmitted to PE1, the PW label is encapsulated to form a data packet, and the data packet is transmitted to PE2 through the path established by the PW, and PE2 decapsulates the received data packet. , peel off the PW label, and send the decapsulated user data to CE2. figure 1 The basic principles of the model shown are generally applicable in the a...

Abstract

The invention discloses a method for realizing time division multiplex (TDM) data transmission. The method comprises the following steps of: transforming a TDM data of a physical layer sent by a local user to a data of a link layer, judging a format of the data of the link layer and performing a corresponding pretreatment operation on the data of the link layer having different formats, PW packaging the pretreated data having different formats, sending to an opposite terminal PE after adding a PW label, paring an outer PW label of a PW packet sent by the opposite terminal PE, judging the format of the data in the PW packet, performing a corresponding de-capsulation operation on the PW packet according to different data formats, transforming the de-capsulated data having different formats into the corresponding data of the link layer, and transforming into the TDM data of the physical layer and then sending to the local user. The invention also discloses a device for realizing time division multiplex (TDM) data transmission. The method and the device of the invention can realize imitating the TDM service on PSN and can further improve the function of the current PWE3 system.

Description

technical field [0001] The present invention relates to an end-to-end pseudo wire emulation (Pseudo Wire Emulation Edge-to-Edge, PWE3) technology in the communication field, in particular to a method and device for realizing time division multiplexing (TDM) data transmission based on PWE3. Background technique [0002] Due to its good openness, wide application and low price, Ethernet has gradually monopolized the information management and communication in the middle and upper layers of the field of communication and process control. However, traditional operators provide a series of existing services based on circuits, such as: TDM, Asynchronous Transfer Mode (ATM), Frame Relay (FR), etc. still have high utilization value, and users still need to rely on these services to support their business needs. The simplest solution is to integrate Internet Protocol (IP) into Ethernet. The proposal of PWE3 technology can enable operators to transfer the above-mentioned valuable ser...
