Embodiment Construction

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Network services show statistical self-similarity in a large scale. The outstanding performance is that bursts have no clear length and show the same burst characteristics at different time scales. The services are long-term correlated and cannot be smoothed out. . Therefore, the self-similarity model is selected as the network traffic model in the present invention. Combining the characteristics of the token bucket algorithm and the self-similar model, the token bucket output traffic model L(t)=rt+b and the self-similar model are used through the loss rate ε Linked, where L(t) is the token bucket output flow, t is the data burst time interval, r is the token generation rate, b is the token bucket capacity, m is the average rate of arriving data traffic, and a is the arriving data Variance of flow rate, Z H (t) is the mean value ...

Abstract

The invention relates to a token bucket traffic shaping method suitable for a fusion network, and belongs to the technical field of data management in fusion networks. By means of the method, through the combination of a token bucket algorithm and self-similar network traffic better conforming to reality, the selection of parameters of token buckets is determined according to the QoS mapping rule between different domains and the relative priority of service, and therefore the parameters of the token buckets are dynamically adjusted according to the cache sharing strategy based on the priority so as to improve the QoS of the whole network service. By means of the design method, the priority of the service can be ensured, the pressure of a device of the fusion network is reduced, and the aim of improving the QoS of service of the whole fusion network is achieved.

Description

technical field [0001] The invention belongs to the technical field of data management in a fusion network, and relates to a token bucket traffic shaping method suitable for a fusion network. Background technique [0002] With the explosive growth of Internet data services, the Internet has gradually developed from a single data transmission network to an integrated transmission network integrating multiple services such as voice, image, and data. Therefore, the new generation of integrated transmission network must be able to provide high-speed, Fast transmission of various services including high bandwidth and real-time services. The traditional single network no longer meets the needs of the current network, so the converged network that combines the advantages of different networks has become a new generation network that meets the needs. Wireless-Optical Broadband Access Network (WOBAN) is currently the most popular converged network. WOBAN combines optical fiber techn...
