Practical Service Chaining based on IP Routing
説明
In this paper, we demonstrate that practical service chaining can be achieved by leveraging existing and standardized IP routing techniques. Service chaining is an emerging network concept for dynamically applying network services to traffic. A straightforward for service chaining is to utilize software-defined networking techniques such as OpenFlow. However, they require additional development costs on both control and data planes and introduce complexity into operation from the practical viewpoint. Our proposed method, called Flowchain, enables us to construct service chaining with standardized IP routing protocols by exploiting the redirect action of BGP Flowspec. Building service chaining with IP routing reduces development cost on both planes and make network management easy. This paper describes how Flowchain achieves service chaining, and our experiments show the feasibility of Flowchain through a demonstration of service insertion and deletion, evaluation of the time required to insert a new service chain, and failover tests.
