Abstract:

In order to solve the load imbalance problem in aviation information network caused by the dynamic changes of service function chain (SFC) requests, a coalitional-game based SFC migration algorithm is proposed. The algorithm regards the aviation platform as the game player and the SFC instance as the game good, which aims to achieve the joint optimization of the network energy consumption and migration overheads.During the execution of the algorithm, the aviation platforms collaborate with each other to build game coalitions, and achieve the SFC migration and network resources integration through the comparison-and-swap operation between different coalitions. The experiment results show that the proposed algorithm has low computational complexity, good convergence performance and is capable to form the Nash-stable structure. Besides, the algorithm can effectively reduce the network energy consumption and migration overhead while maintaining the high resource utilization in different network sizes.

Key words: aviation information network, network function virtualization, service function chain, coalitional game
