Embodiment Construction

[0053]In order to solve the problem that the PPP message cannot be transmitted in the RPR ring network under the prior art, the present invention sets the protocol type of the RPR message header to a specific type after encapsulating the PPP message in the data field of the RPR message, and Send the RPR message to another node in the RPR ring network; the node receiving the RPR message extracts the PPP message from the data field of the RPR message according to the specific RPR protocol type.

[0054] At present, many data link layer protocols adopt a technology of carrying the PPP protocol on the existing data link layer in order to realize the functions already realized by the PPP protocol family (such as automatic negotiation, support for authentication, encryption and compression, etc.) At present, there are technologies such as PPP over Ethernet (PPP over Ethernet, PPPoE), PPP over ATM over ATM (PPPoA), and PPP over Ethernet over ATM over Asynchronous transfer mode.

Abstract

The invention discloses a method of loading a point-to-point protocol on an elastic grouping ring. A first node on the elastic grouping ring packages the message of the point-to-point protocol to a data field of the protocol message of the elastic grouping ring, and then the type of the message heading is set as specific type, and the protocol message of the elastic grouping ring is sent to a second node. The said second node extracts the message of the point-to-point protocol from the data field of the protocol message of the elastic grouping ring, based on the specific type of the message heading. The invention solves the problem that in existing technique, it is difficult to transmit the message of the point-to-point protocol on the elastic grouping ring net. Each node in the elastic grouping ring net can realize authentication of the identity, automatically consulting the parameter of the link layer, automatically consulting the network parameter and data encrypt and compression by the said message of the point-to-point protocol. The invention also discloses a communication device and a communication system.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a method, device and system for carrying a point-to-point protocol on an elastic packet ring. Background technique [0002] Resilient Packet Ring (RPR) technology is a layer 2 ring network technology, which provides a good networking solution for broadband IP MAN operators. Different from traditional MAC technology, the most attractive feature of RPR technology is that it has carrier-class reliability, which enables it to not only complete data-oriented service transmission, but also complete multi-service-oriented comprehensive transmission. It effectively combines SDH's carrier-class features with Ethernet's data service-oriented high-bandwidth distribution features, flexibility and scalability; it provides data-optimized bandwidth management and cost-effective multi-service transmission solutions based on ring topology; When building a data-centric metropolitan area network, it...
