Abstract

Managing computational resources and networking elements over today’s heterogeneous infrastructure has become very challenging. A need for virtualizing network functions has emerged to reduce infrastructure operating costs. In this paper we consider using software-defined infrastructure (SDI) resource management system (RMS) to achieve service chaining of virtualized network functions (VNFs). SDI allows for the integrated control and management of heterogenous resources. In an SDI environment, the end user has access to interfaces that allow programmatic management of the resources. The user can define their own service graph (SG), which determines the path that traffic must take through various VNFs. The ability to dynamically realize the SG is what is referred to by service chaining. Use cases of service chaining include adding a firewall in front of web server and multicasting. Furthermore, we tested the firewall use case in two scenarios to verify validity of our service chaining implementation.
