Embodiment 1

[0090] Such as image 3 As shown, an embodiment of the method for nested networking of the backbone bridging technology specifically includes the following steps:

[0091] Step 101: Divide the network supporting Mac-in-Mac technology into multiple layers, and divide each layer into multiple domains;

[0092] Step 102: Each domain assigns a service label that is only valid in the domain according to the ID of the user class of the next layer accessing the domain in its own way, such as the domain according to the ID of the lower layer accessing the domain The ID (ID=A) of a user class in the domain assigns a service label 1 to this domain, which is used to represent the voice service, and assigns a service label 2 to this domain according to the ID (ID=B) of another user class accessing the domain, Used to represent video services;

[0093] Step 103: This domain sends a mapping request of a service label of this domain to another domain on the same layer through a signaling p...

Embodiment 2

[0098] Such as Figure 4As shown, another embodiment of the method for nested networking of the backbone bridging technology specifically includes the following steps:

[0099] Step 201: Divide the network supporting Mac-in-Mac technology into multiple layers, and divide each layer into multiple domains;

[0100] Step 202: Each domain assigns a service label valid only in the domain to the domain according to the ID of the next-level user class accessing the domain in its own way;

[0101] Step 203: This domain sends a mapping request of a service label of this domain to another domain of the same layer through a signaling protocol (such as a 6MPLS signaling protocol), and the mapping request includes the service label and the ID of its corresponding user class , such as the service label 2 (representing video service) of this domain and its corresponding user class ID=B included in the request;

[0102] Step 204: After the other domain receives the mapping request, it finds...

Embodiment 3

[0107] Such as Figure 5 Shown is an embodiment of the system of the present invention using the backbone bridging technology nested networking method for networking. The system specifically includes the backbone operator's network, the service provider's network and the user's network, a total of three layers of networks, and each layer uses Mac-in-Mac technology. The edge device of the backbone operator network is called B-PE, the edge device of the service provider network is called S-PE, and the edge device of the user network is called U-PE. Common switches (supporting 802.1Q) are used inside each network .

[0108] There are two users in the user network layer, User 1 and User 2. User 1 is divided into two domains, and User 2 is also divided into two domains, a total of four domains; the two domains of User 1, that is, the two branches, respectively pass S-PE1 and S-PE4 are connected to the two domains of service provider 1, and the two domains of user 2, namely the tw...

Abstract

The invention provides a method and system for nested networking of backbone bridging technology, and a method and device for data transmission using the system, belonging to the field of data communication. The present invention manages the label distribution of the network at each level by users at each level, overcomes the defect that the I-TAG label cannot be expanded in the prior art, and realizes the hierarchy of the network and the hierarchy of user access rights; it not only simplifies the management of the network , It also improves the security of the network, breaks through the existing limit of 4K VLANs, and greatly improves the scalability of the networking.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and system for nested networking of backbone bridging technology, and a method and device for data transmission using the system. Background technique [0002] The MAC (Media Access Control, Media Access Control) address is a unique number used to identify itself after each network card is produced. PBB (Provider Backbone Bridges, backbone bridging technology) is Mac-in-Mac technology, which can realize the entire transmission network (layer 2 network ) are all based on the Ethernet architecture, so that the access layer, aggregation layer and backbone layer of the metropolitan area network and even the wide area network can be realized through Ethernet technology, which is an important direction for the development of Ethernet. Due to the advantages of Ethernet's cheapness and ease of use, with the continuous maturity of Mac-in-Mac technology and the related features ...
