Adaptive Resource Allocation Mechanisms for Support of Data Traffic over ATM Satellite Networks
نویسندگان
چکیده
The network scenario addressed here uses a Satellite Access network on an ATMbackbone to provide ATM like services to users over the Satellite Network. The workpresented here is based on our previous work in the area of flow control for data trafficin ATM Networks. We have evaluated the performance of the Satellite ATM Networkwith a proposed Negotiable Call Admission Control (NCAC) Scheme and a dynamicbandwidth allocation scheme called the Uniform Reallocation Dynamic BandwidthAllocation (UR-DBA) Scheme. This work is further extended to support a Rate AdaptiveReallocation DBA (RAR-DBA) scheme. This paper discusses both the UR-DBA andRAR-DBA dynamic bandwidth reallocation scheme. We present the simulated results ofboth the schemes. Minimal cell loss is one of the major considerations of this DBAscheme, besides guaranteeing a minimal cell rate and thereby reduce perceived delayto the user

Satellite ATM Network Architectural Considerations and TCP/IP Performance
In this paper, we have provided a summary of the design options in Satellite-ATM technology. A satellite ATM network consists of a space segment of satellites connected by inter-satellite crosslinks, and a ground segment of the various ATM networks. A satellite-ATM interface module connects the satellite network to the ATM networks and performs various call and control functions. A network cont...
متن کاملAdaptive Description of ATM Traffic Flows1
Today, the great challenge in broad band networks, such as ATM, is to support applications that need guaranteed QoS. Efficient resource allocation for connections that need guaranteed QoS is only possible if the application can provide a precise and reliable traffic descriptor that the network can understand. This work presents a methodology to obtain the parameters of the traffic descriptor of...

An Adaptive Reservation Time Division Multiple Access (AR-TDMA) control protocol for Wireless Asynchronous Transfer Mode (WATM) networks is proposed in this paper. AR-TDMA combines the advantages of distributed access and centralised control for transporting Constant Bit Rate (CBR), Variable Bit Rate (VBR) and Available Bit Rate (ABR) traffic efficiently over a wireless channel. The contention ...
