Abstract

The invention discloses a service chain deployment processing method and device, a computer storage medium and a terminal. The method comprises the following steps: traversing hierarchical topology; determining the shortest path requested by the user according to more than two pieces of preset cost information; converting the shortest path into SFC deployment information; wherein the more than two items of cost information comprise quality of service (SLA) violation cost, and virtualized network function (VNF) deployment and operation cost and / or link bandwidth cost. According to the embodiment of the invention, the SLA violation cost is introduced as a parameter of path search, and is combined with the VNF deployment and operation cost and / or the link bandwidth cost to determine the path for providing the user request, and the introduced SLA violation cost considers the forwarding delay of the user request, so that the quality of an SFC deployment scheme and the user experience are improved.

Description

Technical field [0001] This article relates to but not limited to edge computing techniques, particularly a method, apparatus, computer storage medium, and terminal of service chain deployment processing. Background technique [0002] With the development of mobile communication technology and Internet of Things, mobile network services such as enhancing real-world applications, driving assistant services and personal health assistants are also rapidly increased. Such mobile network services typically have computational intensive features and have different time delay sensitivity requirements. For some time delayed services, the maximum propagation time they can tolerate is often between dozens to hundreds of milliseconds. If such services are deployed to public clouds away from the user, the user's application request is processed, and the traffic data is forwarded through the backbone network, and the delay of the delay sensor is usually unable to meet the delay demand.
