Embodiment Construction

[0045] The technical solutions in the present invention are clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] Such as figure 2 As shown, a queue scheduling-based named data network transmission control method provided by the present invention includes the following steps:

[0047] S1. Make adaptive adjustments to the queue management mechanism, so that the queue management mechanism is actually available on the NDN.

[0048] The queue management mechanism is proposed based on the TCP / IP computer system. The TCP / IP computer system and the NDN network are two different network...

Abstract

The invention discloses a named data network transmission control method, device and apparatus based on queue scheduling. According to the method, static local variables are designed and determined through queue length information under a routing end queue management mechanism; a forwarding strategy is selected according to the static local variables to carry out forwarding decision; the network transmission environment is judged only through the queue length information; the routing end does not need to collect, calculate and distribute information excessively, resource expenditure under datacollection, routing resource calculation and routing forwarding is reduced on the premise that network flow transmission performance is guaranteed and even improved, the utilization rate of resourcesis increased, and timeliness and effectiveness of network flow transmission are improved. The queue length serves as positive feedback of a forwarding decision, the forwarding decision reacts on thequeuing queue, and closed-loop adjustment can be truly achieved.

Description

technical field [0001] The invention belongs to the technical field of network traffic transmission, and in particular relates to a queue scheduling named data network transmission control method, device and equipment. Background technique [0002] With the popularization and development of the Internet, the traditional TCP / IP network architecture has shown a tendency not to adapt to the development of modern networks. NDN (Named Data Networking, NDN) was proposed to solve the current and future network development needs, especially for For large-scale network applications (Internet of Things, big data analysis, blockchain, etc.). While NDN is constantly being considered as a future network requirement, more attention should be paid to the traffic transmission and congestion issues of NDN. [0003] In order to improve the traffic transmission performance of the NDN network, it is necessary to design a more efficient traffic transmission and congestion control mechanism, and...
