Abstract

We have modified the popular Mbone tool vic (VIdeo Conferencing) to use Arequipa (Application REQuested IP over ATM). The latter enables applications and in particular vic, to request a direct ATM connection for its exclusive use and to directly control the traffic parameters of this connection. We have also implemented ATM Forums UNI4.0 signaling and ITU-Ts connection modification recommendation Q.2963.1, on end-systems as well as on switches. This implementation, coupled with the Arequipa mechanism, allowed vic to negotiate and renegotiate ATM bandwidth at will, at run time. We describe how vicaccomplished that over the ATM WAN of SWISSCOM, transferring live video from Lausanne to Basel and Zurich over switched, renegotiable ATM connections. To our knowledge, this was the first time any application had the capacity to tune ATM traffic parameters at run time.

Traffic contract

If a network service (or application) wishes to use a broadband network (an ATM network in particular) to transport a particular kind of traffic, it must first inform the network about what kind of traffic is to be transported, and the performance requirements of that traffic. The application presents this information to the network in the form of a traffic contract. When a connection is requested by an application, the application indicates to the network: The Type of Service required.

Asynchronous Transfer Mode

Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by the American National Standards Institute and ITU-T (formerly CCITT) for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and real-time, low-latency content such as telephony (voice) and video.

End system

In networking jargon, a computer, phone, or internet of things device connected to a computer network is sometimes referred to as an end system or end station, because it sits at the edge of the network. The end user directly interacts with an end system that provides information or services. End systems that are connected to the Internet are also referred to as internet hosts; this is because they host (run) internet applications such as a web browser or an email retrieval program.
