A method and system for sending and scheduling network node multi-service data

Abstract

The invention provides a method for dispatching and dispatching multi-service data of network nodes, and achieves the purpose of shortening the dispatching time and ensuring the timing relationship between data through single-stage dispatching. The implementation process of the present invention includes: 1) the priority of sending data is stored in the sending data priority FIFO group, and each FIFO wherein is all corresponding to a kind of sending data; 2) the priority register group according to the content of effective sending priority FIFO Set the value of each element in the group; 3) select the effective line with the highest priority in the priority register group, and store it in the priority request register; 4) take the priority request register as input, and use the R-R scheduler Get the scheduling result and write it into the scheduling result FIFO; at the same time, send a read clear signal to the corresponding sending data priority FIFO. The invention has short scheduling time, saves the use of on-chip buffers, and guarantees the timing relationship among sending data to the greatest extent.

Description

technical field [0001] The invention relates to a sending scheduling method, in particular to a sending scheduling method of network node multi-service data. Background technique [0002] In the field of network communication, the transmission scheduling method determines key performances such as delay and timing relationship of data transmission. In the current network nodes, multi-service data transmission from different sources generally adopts a two-level scheduling method. First, a scheduling is performed in the data group of the same source, and the transmitted data is read into the on-chip cache corresponding to the source according to the scheduling result. Then schedule the data in the on-chip cache to obtain the final scheduling result. Although this method can realize the data sending and scheduling function, it has the disadvantages that the scheduling takes a long time and will destroy the timing relationship between the data.
