The emergence of software-defined networking (SDN) and network function virtualization (NFV) facilitates policy-driven and dynamic service function chaining (SFC). In recent years, multi-domain SFC orchestration has attracted a significant attention, as it is a complicated problem involving many issues, such as corporation of various administrations and integration of heterogeneous underlying technologies. However, as another critical problem for multi-domain SFC deployment, how to achieve context-aware service provision is still not widely discussed. Thus, in this paper, based on the hierarchical SFC architecture, we allocate metadata to share context information of packets and realize context-based and dynamic SFC in multi-domain networks. We design typical use cases and conduct related experiments about location-aware flow steering and denial of service attack elimination. Experimental results confirm the feasibility and elasticity of our proposed approach. Furthermore, to alleviate the resource over-provisioning problem of context-aware SFC orchestration, we propose a consolidation-based SF placement and chaining algorithm with an online feedback mechanism. We compare the performance of our algorithm with a related greedy algorithm and a tabu search algorithm. Simulation results demonstrate that the proposed algorithm is efficient to reduce the reject rate and improve the revenue-cost ratio, with a compromise on node load balance. |
