Packet Scheduling Method for Multipath Transmission Based on Receiver Buffer Overflow Probability Guarantee

Abstract

The invention discloses a multi-path transmission packet allocation method based on the guarantee of limited buffer overflow probability at the receiving end. The realization steps are as follows: the sending end A estimates the random distribution parameters of the path delay according to the real-time independent path delay information; According to the requirement p of the receiving end buffer overflow probability index required by the user, calculate and solve the sending interval ratio R of the path; the sending end A dynamically adjusts the sending interval of the path and the sending order of the packets according to the given packet allocation method, as much as possible Reduce the number of out-of-order packets to ensure that the limited buffer at the receiving end does not overflow. The present invention can ensure that the cached packets at the receiving end do not overflow as far as possible with the index probability required by the user, reduce the discarding of packets at the receiving end due to out-of-order, ensure the continuity of the upward submission of service data, and improve the throughput of the network , which improves the user experience.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a packet allocation method for multi-path transmission based on the guarantee of limited buffer overflow probability at the receiving end. Background technique [0002] With the diversified development of access technologies and the reduction of equipment costs, users' terminal equipment is gradually equipped with multiple network interfaces. Most of the current notebook computers, smart phones and other mobile terminals have two or more network interfaces. . On the other hand, more and more users tend to download some media services from the network, such as multimedia services such as movies and music. With the increase in the number of users and business types, and the high bandwidth requirements of multimedia services, a single network cannot provide sufficient bandwidth resources to meet user needs. Therefore, multi-path parallel transmission based on multiple acces...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned existing methods, and propose a packet allocation method for multi-path transmission based on the guarantee of the limited buffer overflow probability at the receiving end, to solve the problem of out-of-order packets in multi-path parallel transmission, and ensure the reception as much as possible. The end buffer does not overflow, so that the business data of the sending end user can be continuously submitted to the receiving end
