Congestion control strategies in ATM networks

European Transactions on Telecommunications, 1992

Asynchronous Transfer Mode (ATM) is a promising technique to implement the Broad-band ISDN. When bursty sources are considered, high network efficiency can be obtained by taking advantage of statistical multiplexing. This technique requires to monitor the user behavior, in order to guarantee that the actual traffic parameters do not exceed the maximum values compatible with the required Grade of Service. The paper reviews the major results on the analysis of the control mechanisms. In particular, the three following issues are considered. The Connection Admission Control for both homogeneous and heterogeneous traffic sources is analyzed and the performance of different approaches are compared. The Leaky Bucket mechanism is studied for the Usage Parameter Control and its performance, such as reaction and recovery time, are analyzed. The traffic shaping function is considered in both cases of availability and non availability of a feedback on the traffic sources. The effectiveness of this functionality is investigated.

An Efficient Scheme for Traffic Management in ATM Networks

Novel Algorithms and Techniques In Telecommunications, Automation and Industrial Electronics, 2008

As ATM network is designed for broad band transmission that is high data rate (25 Mbps to 2.5 Gbps) and supports the transmission of every kind of data, congestion control and delay have been important issues for ATM networks. Data transmission is done in the form of cell (53 bytes) relay. Hence, cell sequence and the error control have to be carried out properly. ATM networks presents difficulties in effectively controlling congestion not found in other types of networks, including frame relay networks. In this paper, we present an efficient methodology for traffic management. The simulation results suggest that the proposed solution is effective for both slow and high data rate transmission.

Congestion prevention technique for ATM networks

Proceedings IEEE Southeastcon'99. Technology on the Brink of 2000 (Cat. No.99CH36300)

ATM network does not operate in effective and stable way without preventing Congestion. Traffic management concerns with the design of mechanisms which ensure that the network bandwidth, buffer and resources are efficiently utilized, while meeting the various Quality of Service (QoS) guarantees given to sources as part of a traffic contract. In this paper, A new and improved congestion control scheme is proposed to support the best-effort ABR traffic, as a result of investigating the most widely recognized congestion control schemes for ABR service. Some of these schemes show either lack of scalability or fairness while other well-behaved schemes may require highly complex switch algorithm that is unsuitable for implementation in cell-switching high-speed ATM networks. Our algorithm provides the congestion avoidance ability with high throughput and low delay, in addition of achieving the max-min fairness allocation.

Traffic management Congestion Control Scheme in ATM Networks

2013

The problem of traffic management has been widely recognized as critical to the development of an operational Internet. The goal of traffic management is to efficiently allocated network resources including buffers and bandwidth and provides the negotiated QoS guarantees to users. Rate based Congestion control schemes promises effective traffic management for the ABR service class suitable to data communications in ATM networks. A rate based scheme uses feedback information from the network to specify the maximum rate at which each source can transmit cells in to the network on every VC. In this paper, we considered an efficient rate based congestion scheme, Explicit Rate Indication Congestion Avoidance (ERICA) for ATM networks. An improvement to ERICA scheme is proposed by varying the target rate dynamically.

Preventive congestion control based routing in ATM networks

Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications

In this paper we describe briefly a dynamic multi-path routing algorithm that has been considered for connection oriented Asynchronous Transfer Mode (ATM) networks. Our scheme takes advantage of cell multiplexing capability that has particular advantage in the network supporting the Variable Bit Rate (VBR) traffic. The fundamental objective of the scheme is to propose a congestion control based scheme that bridges the gap between routing and congestion control as the network becomes congested. T h e proposed routing scheme works as a shortest path first algorithm under light traffic conditions. However as the shortest path becomes congested under unbalanced heavy traffic, the source uses multiple paths when and if available in order to distribute the calls and reduce cell loss. This mechanism will provide the clients for good Quality of Service within the given constraints. We compare the performance of the proposed scheme with the other competitive schemes. The throughput and cell loss performance are compared via simulations. These have been carried out concentrating on a 5 node network.

52-2007 A Survey of Congestion Control Schemes for ABR Services in ATM Networks

1998

Broadband integrated services digital network(B-ISDN) efforts are driven by the emerging needs for high-speed communications and enabling technologies to support new integrated services. Among the available technologies, asynchronous transfer mode (ATM) has emerged as a standard for supporting B-ISDN. ATM uses short, fixed-size cells consisting of 48 bytes of payload and 5 bytes of header in order to transmit information. The fixed size allows fast processing of cells and reduces the variance of delay, making the network suitable for integrated traffic consisting of voice, video, and data. Providing the desired QOS for these various traffic types is much more complex than what is done in data networks today.

A Unified Traffic Control Scheme for ATM Networks

The paper proposes a generic traffic control specification at the UNI unifying the characteristics of credit-based and rate-based schemes, and allowing implementation of both, along with other traffic control schemes, simultaneously, in an ATM network.

An approach to controlling congestion in ATM networks

International Journal of Digital & Analog Communication Systems, 1990

Determining approaches to congestion and flow control, especially real-time components in an overall strategy, is recognized as one of the fundamental challenges facing broadband 'packet-based' information transport, as, for instance, in the case of BISDN/ATM. In this paper we summarize basic issues underlying this subject, and describe a particular approach to achieving a multilayer broadband congestion, flow and error-control architecture, based on a 'core' congestion control strategy that we term bandwidth management. The modular and layered nature of this control architecture is described, and shown to lend itself to a structured approach to characterizing the control architecture performance.

Dynamic bandwidth control in ATM networks

Computer Communications, 1999

The Asynchronous Transfer Mode (ATM) principle has been recommended by the ITU as the transport vehicle for future Broadband ISDN Networks. One of the most important objectives of ATM-based networks is to support multimedia traffic services. The multimedia traffic is a diverse mixture of several types of traffic (e.g., video, voice, image, data) that have different correlations, burstiness characteristics and quality of services (QoS) requirements form the network. Efficient bandwidth allocation and access control algorithms are required to ensure (and maintain) specific QoS requirements for each type of traffic. In this article, we propose and analyze a dynamic bandwidth allocation and control scheme based upon the virtual path (VP) principle. The scheme exploits the statistical multiplexing gain principle in order to increase the bandwidth utilization per VP. It allocates a certain amount of bandwidth to each VP that is necessary to meet the QoS requirements of the traffic carried by that VP. Each VP carries only homogeneous traffic (i.e., traffic with similar characteristics and QoS requirements are supported by a single VP). To dynamically control the allocated path-bandwidth a Bandwidth Control Period (BCP) rule is proposed to control the scheduling of different types of traffic that are supported by separate VPs. It is shown that with proper choice of the BCP, a pathbandwidth can be allocated to guarantee QoS required by the traffic. The scheme is dynamic in the sense that the bandwidth allocated, per VP, depends upon the number of accepted calls and variations in the traffic characteristics. Further, it is shown that access flow control is essential in order to minimize the cell loss rate and enhance the statistical multiplexing gain per VP. ᭧

Modeling of Congestion and Traffic Control Techniques in ATM Networks

American Journal of Networks and Communications, 2015

In this Paper, Computer-based Simulation models for effective Congestion control and Traffic management in Asynchronous Transfer Mode (ATM) network have been developed providing a basis for monitoring ATM networks performance for traffic and congestion control purposes ,providing a system with a reduce short-term congestion in ATM networks, and enhancing a fair operation of networks in spite of the challenges in designing ATM traffic management system to make maximal use of network resources. An IDCC scheme was implemented, applying IDCC methodology to the ATM Network. Using analysis performance, limits were created for robust controlled network behaviour, as dictated by reference values of the desired queue length. By tightly controlling output of the controller, the overall network performance was adjusted and also controlled. A simulation tool, MATLAB/SIMULINK, was used for this purpose. An improvement was observed in the delay performance of ATM networks. The results were obtained by running several simulations and populating a table with the outcome over a number of simulation runs. The effectiveness of the congestion control techniques was tested by analysing the dynamic performance of the model through variation of some parameters. The performance of this model proved to be efficient if applied in the ATM network of today.
