What is a service router?

service router

A large portion of Internet traffic is organized by Content Delivery Networks (CDNs). CDNs redirect to a suitable server through domain name servers (DNS). At the same time, in future networks, network routers are expected to be equipped with more processing and storage power modules to provide the most efficient end-user services. From this perspective, a service-oriented router (SoR) is introduced to accelerate content-based services. This work presents a new method, DNS and SoR Collaborative Redirection (DSCR), to speed up a redirection to the end-user. DSCR uses SoRs to collect and store server and network status information by placing SoRs at the edges of the ISP network. The DSCR then uses the information gathered to accelerate DNS-based end-user redirects. We present the design and implementation of the DSCR prototype and demonstrate how both SoR and DNS can leverage existing Internet architecture to accelerate redirection to the end-user. A detailed simulation was completed to evaluate our proposed method using different strategies. The simulations clearly demonstrate the effectiveness of the collaborative approach, which results in a 5-10% reduction in end-user latency compared to DNS-based redirection.
