Adaptive buffer threshold updating for an ATM switch
نویسندگان
چکیده
Efficient and fair use of buffer space in ATM switch is essential to gain high throughput and low cell-loss performance from the network. A shared buffer architecture associated with threshold based virtual partition among output ports is proposed. Thresholds are updated based on trajfic characteristics on each outgoing link, so as to adapt to traf$c loads. System behavior under varying trafJic patterns is investigated via simulation. Cell loss rate is the quality of service(QoS) measure that is used in this paper The study shows that the threshold based adaptive buffer allocation scheme ensures,fair share of the buffer space even under bursty loading conditions.

Performance 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...
متن کاملWork Group 1 ( For Technologies ) TITLE : A Fast and Efficient Buffer Sharing Scheme for an Input Buffer ATM Switch
In this paper a fair and fast buffer sharing scheme based on the round robin cell distribution mechanism for an input buffer ATM switch is proposed. This buffer sharing scheme improves the performance of the input buffer ATM switch in terms of the cell loss ratio and the CDV by equalizing the occupancy of input buffers. In order to make the equalizing and buffer sharing operation fast and simpl...
متن کاملAn output-shared buffer ATM switch
An output-shared buffer ATM switch is proposed in this paper. This switch sits between an output-buffer ATM switch and a shared-buffer ATM switch. It offers better buffer utilization than a pure output-buffer ATM switch. It also has lower bandwidth requirement than a pure shared-byffer ATM switch.
متن کاملDimensioning of an ATM Switch with Shared Buffer and Threshold Priority
A number of recent studies have addressed the use of priority mechanisms in Asynchronous Transfer Mode (ATM) switches. This investigation concerns the performance evaluation and dimensioning of a shared-buffer switching element with a threshold priority mechanism (partial buffer sharing). It assumes that incoming ATM ceils are distinguished by a space priority assignment, i.e., loss of a high p...
متن کاملDesign, Analysis of an ATM Switch With Priority Discarding Scheme
In this paper, we propose an N × N high speed and non-blocking asynchronous transfer mode (ATM) switch with input and output buffers. In this switch, each buffer adopts a priority discarding scheme, which discards incoming cells of low-priority traffic when its queue length is greater than a predefined threshold value. Our switch also supports broadcast/multicast functions without increasing th...
