Abstract

The invention discloses a dual-stack differentiated scheduling method and device, comprising: classifying data packets according to priority and protocol version number; scheduling according to the classified data packets; wherein, the data packets with the same priority are classified as IPv4 Data packets and IPv6 data packets are put into different priority queues. The invention can perform differentiated scheduling on IPv4 data packets and IPv6 data packets.

Description

technical field [0001] The present invention relates to the field of next-generation Internet technology and IT equipment technology, in particular to a dual-stack differentiated scheduling method and device. Background technique [0002] With the completion of the allocation of public IPv4 addresses, the evolution of networks and services to the IPv6-based next-generation Internet has become an inevitable trend, and IPv4 and IPv6 will coexist for a long time. In a dual-stack environment, most applications prefer to use the IPv6 protocol for access. This access mechanism is conducive to promoting the growth of IPv6 traffic and promoting the evolution of existing networks and services to IPv6. [0003] In the priority queue scheduling, after the network device receives the data packet, it classifies the data packet according to the priority of the data packet, puts the data packet into different priority queues, and sends the higher priority according to the order of priority...
