Embodiment Construction

[0086] The present invention will be further described below in conjunction with the accompanying drawings.

[0087] The present invention takes figure 1 The upper-layer multi-hop schematic diagram of the wireless network gateway is shown as an example. In this scenario, the service volume of the gateway near the user is saturated, and the user task needs to be transmitted to a distant idle gateway for task processing, or the user near the gateway needs to interact and share information with the gateway user farther away. Jump. In the multi-hop scenario, a software-defined network is introduced, and there are multiple paths between the source and destination hosts. For example, the traffic path a and traffic path b in the figure above have the same source-destination pair, but the paths are completely different. The routing selection is random, so The present invention introduces random probability parameter (P [.].a ,P [.].b ,P [.].c ) to represent this randomness, abstr...

Abstract

The invention discloses a service end-to-end performance analysis method for introducing random probability parameters. The method comprises the steps of introducing the random probability parametersaccording to the characteristic that the routing selection of a wireless network introduction software-defined network is random; dividing the service priorities in the network into a high priority, amedium priority and a low priority by adopting a preemptive priority scheduling method; utilizing a random network calculation method based on a moment mother functions, and according to a Chenov inequality, a series theorem in random network calculation, a residual service theorem, convolution and a theorem, obtaining closed expressions of relationships between time delay and backlog upper boundboundaries and default probabilities when three priority businesses are used as research objects respectively.

Description

technical field [0001] The invention relates to the technical field of communication networks, and mainly relates to a service end-to-end performance analysis method that introduces random probability parameters. Background technique [0002] In a wireless network, if the service saturation of the gateway near the user cannot meet the user's needs, the task will be forwarded to other gateways with service capabilities for task processing, or when the users near the gateway share data and information interaction with users of other gateways, Multi-hop implementation is required. In the wireless network, the software-defined network technology is used to separate the control plane and the data plane of the network, integrate various resources such as computing, transmission and storage in the network, perform centralized management and distribution, and flexibly control the forwarding of network traffic. The wireless network routing selection introduced into the software-defi...
