Embodiment Construction

[0049] figure 1 The network topology diagram provided for an embodiment of this application, such as figure 1 As shown, the network elements involved in the network topology are routers, including: routers A, B, C, D, E and Z. Edge routers include: routers A, B, E, and Z, directed edges include: AB, AD, AC, BD, CD, CZ, CE, DZ, and EZ, edge attributes include: bandwidth, propagation delay, etc., node attributes include : Buffer queue capacity, queue delay, etc. There are four data streams (also referred to as aggregation streams) in the network topology, including: data streams on AZ, AE, BD, CD, and CZ.

[0050] For each data flow, a router can usually select multiple paths for data transmission. Assume that for the data flow on AZ, router A can choose paths A-B-D-Z, A-D-Z, A-C-E-Z, and A-C-Z for data transmission. Correspondingly, the existing router A’s The routing forwarding table is (A, Z, B, D, C), where A represents the source router, Z represents the destination rout...

Abstract

The present application provides a traffic scheduling method and device. It includes: the network device sends the first partial state information of the network device to the controller, and the first partial state information is used to generate the first global state information of the network device; the network device receives the first global state information sent by the controller; the network device according to The first global state information generates a first traffic scheduling instruction, the network device receives the first traffic scheduling instruction sent by the controller, and the network device performs traffic scheduling on the first data flow to be transmitted according to the first traffic scheduling instruction. Since each network device communicates with the controller instead of broadcasting, the controller generates global state information based on each local state information, thereby solving the problem of excessive communication traffic.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a traffic scheduling method and device. Background technique [0002] Network traffic scheduling refers to a process of generating a traffic scheduling instruction for a data flow to be transmitted, and performing traffic scheduling through the traffic scheduling instruction. For example, the traffic scheduling instruction may be a traffic scheduling ratio of the data flow to be transmitted on at least one link. For users, the shorter the transmission time of the data stream to be transmitted and the minimum degree of network congestion, the higher the reliability of the network. [0003] The existing technology provides a deep reinforcement learning method to generate traffic scheduling instructions for the data stream to be transmitted, train a deep neural network (Deep Neural Network, DNN) for each router, and determine the generation of the data stream t...
