Abstract
In FAN, when the outgoing link is congested, new flows cannot be accepted by MBAC. A congestion state may be observed for a long time, which may not be acceptable for streaming flows implementing tasks such as real-time transmissions, for example VoIP (Voice over IP). It should be noted that according to Network grade of service parameters and target values for circuit-switched services in the evolving ISDN (ITU-T Recommendation E.721 (1999)), the setup time (post-selection delay) for local calls should be less than 6 s, while for international calls it should not exceed 11 s. The main motivation for the introduction of congestion control mechanisms in the MBAC block of XP routers is to reduce the access time to the congested link for new streaming flows.
The Internet “browser”…is the piece of software that puts a message on your computer screen informing you that the Internet is currently busy and you should try again later.
