Embodiment Construction

[0029] When routers are used to complete the forwarding between the internal network of a small area and the optical transmission system, the cost is high due to the use of routers to complete service data forwarding; and the service data transmission between the router and the service boards that manage small area services will also take up additional time and resources, and if routers are not used, direct forwarding by the optical transmission system will occupy considerable line bandwidth, affect the transmission of normal business data, and reduce network efficiency.

[0030] In order to solve the problem of high cost and low efficiency when using a router to complete data forwarding, the embodiment of the present invention provides a data forwarding method, the method uses a service board such as figure 2 As shown, it includes a CPU 201, a routing chip 202 and a data processing chip 203; wherein, the routing chip 202 and the data processing chip 203 are connected through ...

Abstract

The invention discloses a data forwarding method and a service single board, relates to the field of data transmission, and solves the problems of high cost and low efficiency brought about by using a router to finish data forwarding. The data forwarding method comprises the following steps that: a router chip receives service data and judges the data type of the service data; and if the service data is external service data, the router chip forwards the external service data to a data service processing chip through an internal bus of the service single board. The technical scheme provided by the invention is applied in an internal network under an optical transmission system.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data forwarding method and a service single board. Background technique [0002] The business area covered by the optical transmission system includes some small areas. The traffic in these small areas is small, and only data services need to be transmitted between these small areas. The services in such small areas are called internal services in this paper. , the network in a small area is called an internal network, and several small areas can also be combined to form an internal network. Generally, internal services are not transmitted through the optical transmission system to avoid occupying bandwidth. [0003] The usual way to deal with internal business is to add routers outside the system, such as figure 1 As shown, the forwarding of the service data of these services between the internal network of the small area and the optical transmission system is realized by th...
