Router for sensing bearing state and service flow bandwidth distribution method thereof

Abstract

The invention provides a router for sensing a bearing state and a service flow bandwidth distribution method thereof. The method comprises: a bandwidth distribution strategy generation step for all services; to be specific, collecting bearing state information of a router and quality of service (QoS) demand information of a service flow, employing bandwidth distribution algorithm that is provided based on a cognitive network technology to carry out analyzing and processing on the collected data, and integrating a plurality of set rules and using difference of QoS demands of various service flows for reference to generate a bandwidth distribution strategy for all the services; and a step for distributing bandwidths for all the service flows; to be specific, mapping the strategy into an operation instruction that can be identified by the router according to a requirement of configuration strategy and executing the operation to change router queue management so as to carry out bandwidth distribution on the service flows. According to the invention, the cognitive network technology is utilized to realize sensing of a network bearing state and a service flow state, so that network bandwidth distribution can fully consider a dynamic changing characteristic of the network to enable the distribution mode to become reasonable.

Description

technical field [0001] The invention relates to computer management, in particular to a bearer state-aware router and a method for allocating service flow bandwidth. Background technique [0002] An important content of network management is the allocation of network bandwidth. The allocation of network bandwidth refers to the control of the bandwidth resources occupied by different services or data flows on the network switching nodes according to certain rules or service level agreement SLA (Service Level Agreement). At present, the methods of bandwidth allocation on the Internet can be roughly divided into two types: static allocation methods and dynamic allocation methods. [0003] The static bandwidth allocation method usually reserves enough bandwidth for each service flow to guarantee its QoS. This method is often used in call admission control systems (Call Admission Control) and resource reservation systems (Resource Reservation). Typical An example is a system ba...

Problems solved by technology

[0014] The purpose of the present invention is to overcome the lack of awareness of the network bearer status in the current dynamic bandwidth allocation method, that is, a few methods based on bearer status awareness are only limited to the perception of bearer traffic, and cannot be based on the bearer status of the underlying physical network. bandwidth allocation; on the other hand, most of the existing dynamic bandwidth allocation methods are too coarse for the classification granularity of the service flow, and cannot finely manage the bandwidth allocation of the service flow, so as to provide a state-aware router and its service Stream Bandwidth Allocation Method
