Design And Implimentation Of Resource Awareness Mechanism And System For Computing Force Network

The computing force network is a new information infrastructure that provides integrated services based on the deep integration of computing power and network.The computing force network can schedule computing services to the most matching computing service node according to the needs of computing services,combined with the perceived real-time computing power and network resource state,so as to improve the utilization of computing power and network resources.The real-time awareness of the state of computing power and network resources is the basis for the rational allocation of computing power and network resources,and the realization of on-demand scheduling of services.It is also a key technology in computing force networks.Network measurement is required to sense the state of network resources.However,the traditional active/passive measurement method has inherent defects such as indirect measurement results and limited data collection types.The existing mode of INT(In-band Network Telemetry)technology cannot meet the requirements of the richness of measurement content and low data output overhead at the same time.In terms of state awareness of computing power resources,the current proposed computing power notification method of flooding the state information of computing power resources by extending the BGP routing protocol will generate a large number of additional flooding messages,and the network bandwidth cost is large.To solve the above problems,this paper designs a resource awareness mechanism for computing force network,and implements a resource awareness system for computing force network.The system can enable the entry node in the computing force network to perceive the network resource state information such as delay,jitter,packet loss rate,and the computing power resource state information of the network edge computing service node.The work of this paper mainly includes two aspects.First of all,this paper designs a new INT mode,INT-HX(Hybrid Data Export)mode,and on this basis designs a resource awareness mechanism for computing force network.This mechanism exports INT metadata in a mixed way.It supports hop-by-hop measurement of delay,jitter,and packet loss rate,and reduces the overhead of exporting INT metadata.In addition,the mechanism completes the announcement of computing power resource state information through the forwarding of INT packets,and does not generate additional packets,reducing the network bandwidth overhead.Secondly,on the basis of the above mechanism,this paper implements a resource awareness system for computing force network through VPP(Vector Packet Processing)platform.The system includes resource awareness data layer,resource awareness management layer and resource awareness display layer.The experimental results verify the availability of the system and the effectiveness of the resource awareness mechanism for computing force network:compared with the existing mode of INT,this mechanism supports the measurement of the hop-by-hop packet loss rate and the carrying and forwarding of the state information of computing power resource,and reduces the export cost of INT metadata.
