Next-generation network architectures support complex services in the data-path of routers. A key challenge is the integration of multiple policy constraints from senders, receivers, and network providers when using such services. We introduce a multi-party service specification framework based on our “service socket” API. We illustrate the operation of this approach in an IPTV scenario that uses a video transcoding service implemented on a Cisco ISR platform.
