Abstract

This paper proposed a cross-domain mapping algorithm of service function chain based on deep reinforcement learning in view of the influence of SFC mapping on transmission delay and resource cost in the partial information isolation. Firstly, this paper constructed a centralized choreography architecture, which the upper controller utilized the full mesh aggregation technology to construct the abstract topology and reduced the complexity of mapping between domains. Secondly, this paper modeled the SFC request partition problem as Markov decision process, so that virtual network function could evenly distribute in each domain. Finally, this paper constructed the deep reinforcement learning network when taking the inter-domain transmission delay and mapping resource cost as reward function, and completed the inter-domain mapping by training. If the intra-domain mapping fails, used the feedback mechanism to improve the acceptance rate of SFC requests. Simulation results show that the proposed algorithm can effectively reduce the transmission delay and resource cost. Meanwhile, it can improve the request acceptance rate.
