Abstract :
Nowadays, a video conference service is a provider-dependent service, in which conferencing users must manually pre-install same conferencing software before a conferencing session startups. Furthermore, the conferencing users must comply with requirements of the un-adaptable service. In this paper, we propose an active video conference service (AVCoS) over Yuan active networks (YAN) [Yang-Hui Chang et al. (2002)]. Following YAN architecture, AVCoS consists of application, value-added and network generic layer components. The components are extendable, replaceable and deployable. Via service compositions of YAN, AVCoS allows a user can customize a template service describing profile, called "ASDI", which describes how to composite those components. Therefore, the user can adapt functionalities of the service by a homepage to meet current conference node environment and network environment Then, Active Service Deployment Protocol (ASDP) will deploy software components of AVCoS to active nodes and the users on the fly according to customized ASDI. Thus, AVCoS adapts itself to meet heterogeneous users
