Problems solved by technology

At present, many SDH-based multi-service transport platform (MSTP) devices encapsulate the Ethernet services from the same Ethernet port and map them to the same or several SDH time slots as a whole, so the same port The Ethernet service can only reach the same destination, so it cannot support the multi-directionality of the Ethernet service. Therefore, the Ethernet service needs to be processed again outside the transport network before it can be transmitted to its destination address.
Therefore, Ethernet services require both Ethernet switching equipment (routers or switches) and SDH equipment with Ethernet interfaces during the transmission process. This kind of transmission network not only causes waste of resources to some extent, but also makes The cost of input is high

Embodiment Construction

[0023] In order to deeply understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] As shown in Fig. 1, the present invention is mainly made up of Ethernet two-layer switch chip 1, SDH framer 2 and control module 3, Ethernet two-layer switch chip 1 has m line side interfaces and n system side interfaces, wherein m is less than or equal to n, the Ethernet Layer 2 switching chip 1 inputs Ethernet service data through the line side interface, and connects with the SDH framer 2 through the system side interface. Business data is forwarded according to the relevant protocols of Layer 2 and Layer 3 switching, such as the address forwarding table for address self-learning, IP routing table, etc., or the corresponding system-side static configuration interface is selected according to the control command of the control module, and the data from the same line-side interface ...

Abstract

The disclosed multilink transmission device supporting the access of Ethernet business comprises: a SDH framing device connected with a control module, and an Ethernet dual-layer exchange chip with a wire side and system side interfaces that connects with the framing device and control module and sends Ethernet business data from wire side interface to corresponding system side interface as their objective then to the framing device. This invention saves exchange device and reduces cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a multi-link transmission device supporting Ethernet service access. Background technique [0002] In the transport network, before the Ethernet access transmission equipment transmits Ethernet services, it is necessary to use SDH (Synchronous Digital Multiplexing) framing device to adapt the Ethernet services to the transmission link with time slots as the granularity in a certain way . At present, many SDH-based multi-service transport platform (MSTP) devices encapsulate the Ethernet services from the same Ethernet port and map them to the same or several SDH time slots as a whole, so the same port The Ethernet service can only reach the same destination, so it cannot support the multi-directionality of the Ethernet service. Therefore, the Ethernet service needs to be processed again outside the transport network before it can be transmitted to its destination address. Therefore, Et...
