The growing interest in multicast applications for the Internet, that will increase with the introduction of active network technology, brings out the need for providing effective congestion control mechanisms. This paper studies the problems and specific requirements for multicast congestion control. From this study, a general mechanism is proposed and its(More)
Active network technology enables fast deployment of new network services tailored to the specific needs of end users, among others features. Nevertheless proper charging for these new added value services require suitable authentication and authorization mechanisms. In this article we describe a security architecture for SARA (Simple Active(More)
Active network technology enables fast deployment of new network services tailored to the specific needs of end users, among other features. Nevertheless, security is still a main concern when considering the industrial adoption of this technology. In this article we describe an open security architecture for active network platforms that follow the(More)
We propose a scenario of a multiservice network, based on pragmatic ideas of programmable networks. Active routers are capable of processing both active and legacy packets. This scenario is vulnerable to a Denial of Service attack , which consists in inserting false legacy packets into active routers. We propose a mechanism for detecting the injection of(More)
This paper aims to provide insight into the behavior of congestion control mechanisms for reliable multicast protocols. A multicast congestion control based on active networks has been proposed and simulated using ns-2 over a network topology obtained using the Tiers tool. The congestion control mechanism has been simulated under different network(More)
