Sigmoid Function Based Dynamic Threshold Scheme for Shared-Buffer Switches
نویسندگان
چکیده
Buffer space in packet switching nodes is an important network resource. Shared buffer switches are prone to high packet losses and unfair use of buffer space. The use of a buffer management scheme is necessary to overcome these problems. This paper investigates the performance of Sigmoid Function Threshold scheme by means of simulations. This scheme regulates the usage of shared buffer space by employing multiple thresholds for packet admission. The results show that it performs well under non-uniform input traffic; nevertheless buffer space reserved for lightly loaded output ports is wasted due to the strict packet admission control.

Dynamic Queue Length Thresholds For Shared-memory Packet Switches - Networking, IEEE/ACM Transactions on
In shared-memory packet switches, buffer management schemes can improve overall loss performance, as well as fairness, by regulating the sharing of memory among the different output port queues. Of the conventional schemes, static threshold (ST) is simple but does not adapt to changing traffic conditions, while pushout (PO) is highly adaptive but difficult to implement. We propose a novel schem...
متن کاملDynamic Partitioning: A Mechanism for Shared-Memory Management
In this paper, we propose a novel buffer management scheme in order to regulate the individual queue lengths in a shared-memory switch. The primary motivations of our scheme are: i) provide differentiated allocations to the queues sharing the memory, where the allocations are directly derived from the Call Admission Control (CAC) parameters; ii) allow for the co–existence of regulated and best-...
متن کاملThreshold-based Partial Sharing Buffer Management in a Shared Buffer Packet Switch
In a shared buffer packet switch, a good buffer management scheme will reduce the overall packet loss probability and improve the fairness among different output queues. In this paper, a novel buffer control scheme called threshold-based partial sharing (TPS) is proposed. The key idea of the TPS is to separate the output ports into active and inactive output ports according to whether their que...
متن کاملExponential Decay Queue Thresholds for Optimal Buffer Sharing
In an N x N shared buffer switch architecture, a common buffer space is shared among output ports, which provides flexibility in resource allocation. However the problem arises when the buffer space is dominated by one or more output ports in case of imbalanced input traffic. Thus this results in an increased packet loss rates due to unfair sharing of buffer space. For this reason buffer manage...
متن کاملPerformance improvement of dynamic buffered ATM switch
Performance of ATM networks depends on switch performance and architecture. This paper presents a simulation study of a new dynamic allocation of input buffer space in ATM switching elements. The switching elements are composed of input and output buffers which are used to store received and forwarded cells, respectively. Efficient and fair use of buffer space in an ATM switch is essential to g...
