Embodiment Construction

[0046] Such as Figure 1-6 As shown, the congestion control method of DiffServ provided by the present invention is described in detail as follows:

[0047] Most of the existing congestion control mechanisms for pull communication semantics focus on how to maximize the utilization of network resources and how to ensure the fairness among different flows, but rarely consider the distinction of different service flows. However, in actual network scenarios, due to the diversity of network applications, services of different business types have different requirements for transmission performance, that is, different tolerances for data transmission delays, packet loss, and jitter. Failure to differentiate between these different categories of services will result in a poor network experience for users. In order to solve this problem, the technology of the present invention proposes a pull communication semantic congestion control method for differentiated services, which provides ...

Abstract

The invention is applicable to the field of network congestion control technology improvement, and provides a service-differentiated congestion control method, which comprises the following steps of: S1, realizing hop-by-hop interest packet rate shaping at a router by using a weighted fair queue and a token bucket algorithm; s2, calculating a target rate of each stream by the router, and carrying the target rate to a receiving end by a returned data packet; s3, the receiving end sets the rate of sending the interest packet in the next time period according to the target rate value carried by the data packet; and S4, the router dynamically adjusts the traffic forwarding proportion of each interface according to the rate shaping result and the target rate value carried in the data packet returned from the upstream. Convergence time is greatly reduced, and stability of a network system is facilitated.

Description

technical field [0001] The invention belongs to the technical improvement field of network congestion control, in particular to a congestion control method for differentiated services. Background technique [0002] In recent years, with the rapid development of new network services such as smart mobile devices, the Internet of Things, and cloud computing, the amount of global information has shown an exponential growth trend. The change and improvement of the network architecture is inseparable from the various needs of a large number of Internet users for the rapid transmission of massive information, distributed storage and big data applications. The upper-layer network applications based on the TCP / IP communication protocol have become extremely rich and gradually formed. The current communication paradigm whose main purpose is to obtain network content is changed. The main purpose of users to surf the Internet is no longer to communicate with a certain host, but to brows...
