An objective of the next. generation network is the accommodation of services wit,h different QoS requirements. This indicates that the network should provide special mechanisms in order to prioritize the access to network node resources, such as link capacity and buffer space. We studied the performance of sharing buffer space and link capacity bet.ween sessions, the traffic of which is modele...

A high-quality MPEG-2 software decoder should support a good scalability performance for a wide range of video format, especially for the high-resolution MPEG-2 video (e.g., HDTV). However, It is found that the existing parallel decoder suffers significant performance degradation when decoding high-level MPEG2 video with the full system configuration, due to inefficient management of memory spa...

Ž . Efficient and fair use of buffer space in an Asynchronous Transfer Mode ATM switch is essential to gain high throughput and low cell loss performance from the network. In this paper a shared buffer architecture associated with threshold-based virtual partition among output ports is proposed. Thresholds are updated based on traffic characteristics on each outgoing link, so as to adapt to tra...

In the paper a new efficient algorithm for the allocation of storage capacity in serial production lines is derived. The proposed method aims to find out the distribution of storage capacity between machines that minimizes the total buffer space assigned to the line satisfying a target production requirement. The algorithm relies on an iterative scheme that, starting from the minimal capacity r...

In the reordering buffer management problem a sequence of requests arrive online in a finite metric space, and have to be processed by a single server. This server is equipped with a request buffer of size k and can decide at each point in time, which request from its buffer to serve next. Servicing of a request is simply done by moving the server to the location of the request. The goal is to ...

Current standards reserve one bit in the ATM cell header to indicate loss priority. When congestion occurs ai a queue lower priority cells can be discarded in order to insure a smaller cell loss rate for higher priority cells. Strategies for determining which cells to discard are termed space priority buffer management schemes. In ihis paper two adjustable space priority schemes are studied, wh...

JOINT BUFFER MANAGEMENT AND SCHEDULING FOR INPUT QUEUED SWITCHES by Dequan Liu Input queued (IQ) switches are highly scalable and they have been the focus of many studies from academia and industry. Many scheduling algorithms have been proposed for IQ switches. However, they do not consider the buffer space requirement inside an IQ switch that may render the scheduling algorithms inefficient in...
