Abstract

The invention discloses a fast and load-balanced service function chain deployment method in a dynamic network environment. Most of the traditional service function chain deployment algorithms are proposed separately for multi-server network or data center network and do not have universality, As that method of the invention can be used in a multi-server network, or in a data center network, and is not limited by the size of the network; compared with traditional deployment algorithms, the invention has a wider application range, the reinforcement learning module is used to learn the network topology links, combined with the load balancing module, the shortest path which is close to the optimal solution can be obtained, Moreover, the invention can accept more SFC deployment requirements, and the total profit of the found deployment scheme is higher than that of the traditional deployment algorithm. Under the condition of effective training, the invention can output the SFC deployment scheme quickly. Compared with other high-accuracy deployment algorithms, the algorithm speed of the invention is much faster.

Description

technical field [0001] The invention relates to the technical field of dynamic network service function chains, in particular to a fast and load-balanced service function chain deployment method in a dynamic network environment. Background technique [0002] Most networks today use a large number of dedicated hardware appliances that provide functions such as firewalls and network address translation (NAT). Various services provided by service providers usually require specialized hardware devices. With the continuous expansion of network scale and the rapid expansion of emerging industries such as big data and cloud computing, starting a new service requires the deployment of various dedicated hardware devices, making it extremely difficult to design private protocols and protect user data security. Since users share resources on dedicated hardware devices, hackers can easily obtain a large number of users' data by exploiting certain security vulnerabilities of certain dev...
