The traffic increase and its very nature (which is self-similar) necessitated revising in a drastic manner the plans for Internet development. Moreover, different forms of information (notably multimedia) have created a need to stress quality of service requirements allowing request for special treatment of certain traffic flows. Efforts in that direction include resource reservation signaling protocol (RSVP), integrated services architecture and differential services. All these developments led thinking about a new generation Internet in general general an Internet 2 initiative for the universities and research communities. A base for these developments is the implementation of vBNS (very high speed Backbone Network Service). For the Internet 2 project, a separate project called Abilene is expected to supply its backbone. Also, a new Internet protocol IPv6 is expected to support: both unicasting and multicasting, prefix routing and aggregation, an increased minimum transfer unit, and an expanded addressing scheme. Emphasis is also an real-time applications with the introduction in the application layer of the real-time streaming protocol (RTSP). Finally, with the need for mobile access to the Internet, the existing protocol is being modified to take these requirements into account.","PeriodicalId":250544,"journal":{"name":"Proceedings of the Sixteenth National Radio Science Conference.

A closed control loop between the source and the destination is performed to implement flow control for ABR services. The source sends resource management (RM) cells with the data cells to be used to indicate the sending station's current transmission rate and the higher rate it would like to use. Based on this information the available cell rate (ACR) which the network can afford is calculated. This is performed in three different ways known as explicit forward congestion identification (EFCI), relative rate marking (RRM) and explicit proportional rate control algorithm (EPRCA). In this paper the combination of the three different schemes is considered. A general formula for evaluating ACR value is given when two network conditions are considered, namely heavy load and moderate load. The new ACR value is calculated based on a feedback acknowledgement from the bottleneck switch. This acknowledgement suggests a new ACR value namely explicit rate (ER)-a rate that the congested switch can afford. A computer simulation is performed to examine the performance of a network consisting of two ATM switches applying the previously mentioned control schemes. High performance is achieved when using the explicit rate (ER) determined by the congested switch.","PeriodicalId":250544,"journal":{"name":"Proceedings of the Sixteenth National Radio Science Conference.
