Embodiment Construction

[0026] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0027] Such as figure 1 Shown is the network model diagram of the preferred embodiment of the present invention. These include: shapers, network domains, cloud service domains. The network domain also includes an ingress router node and an egress router node, and the heterogeneous flow multiplexing module and admission control module of the present invention are deployed in the ingress router node of the network domain.

[0028] figure 2 Shown is the node multiplexing model of the service flow (heterogeneous flow) of the pre...

Abstract

The invention discloses a cloud service-oriented admission control method for converged flows, and belongs to the field of network management and network QoS (quality of service) assurance. The admission control method comprises the following steps of initiating a request of accessing cloud service by a user side, shaping through a shaper to obtain a plurality of shaped business flows, and converging the shaped business flows to produce the converged flows through multiplexing of a multiplexer; computing the effective bandwidth EB and / or the equivalent capacity EC of the converged flows by adopting a network calculus method; admitting the user request when the effective bandwidth EB is not bigger than C, and otherwise, rejecting the request; admitting the user request when the equivalent capacity EC is not bigger than C to allow a user to enter a network domain, and otherwise, rejecting the request. Compared with a traditional admission control method for uniflows, the admission control method for the converged flows disclosed by the invention is capable of admitting more business flows when the node output rate is fixed, i.e., the network throughput is increased.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to cloud service-oriented network QoS guarantee and admission control technology. Background technique [0002] With the development of cloud computing, the number and types of cloud services have exploded. Users who want to receive services in the cloud must go through the traditional network. This makes the traditional network with limited resources (such as bandwidth, buffer length, etc.) Congestion may occur and cause the threat of cloud service quality (Quality of Service, QoS) decline. In addition, users have higher and higher requirements for service quality, and the traditional "best effort" service of the network can no longer meet the QoS requirements of users. As an effective preventive flow control method, admission control is an important technology to avoid network congestion and realize network quality of service (QoS). A network that implements admission...
