The authors present NetServ, node architecture for deploying in-network services in the next generation Internet. NetServ-enabled network nodes provide a common execution environment, where network services implemented as modules can be dynamically installed and removed. They demonstrate three such modules. MicroCDN is a dynamic Content Distribution Network (CDN) service which implements a content caching strategy specific to a content provider. The NAT Keep-alive module offloads the processing of keep-alive messages from SIP servers. The media relay module allows any NetServ node to act as a media relay, eliminating the need to manage standalone relay servers.
