A buffer allocation algorithm for wormhole routing networks-on-chip was proposed. When the total budget of the available buffering space is fixed, the proposed algorithm automatically assigns the buffer depth for each input channel, in different routers across the chip, according to the traffic characteristics of the target application. The simulation results show that the buffer allocation res...

Periodic broadcast is a cost-effective solution for large-scale distribution of popular videos because this approach guarantees constant worst service latency, regardless of the number of video requests. An essential periodic broadcast method is the client-centric approach (CCA), which allows clients to use smaller receiving bandwidth to download broadcast data. An enhanced version, namely CCA+...

We analyze closed Engset service systems with requests having some random space requirement (volume) under assumption that service time of the request depends on its volume. We also assume that each customer (or source of requests) is characterized by his own join distribution of the request volume and service time, and the total requests volume is limited. For such systems we determine the sta...

A deterministic service model assisted by a sufficiently large playback buffer space can provide bounded delay guarantees for video packets and simplify network resource management. However, many popular mobile terminals do not have sufficient memory capacity for deterministic video services since the embedded memory is limited and needs to be shared by numerous software programs and masses of ...

Delay Tolerant Networks (DTNs) are a class of emerging networks where disconnections may occur frequently due to propagation phenomena, node mobility, and power outages. Delay is inevitable in DTNs, thus, making better use of buffer space to maximize the packet delivery rate is more important than concentrating on how to decrease the delay. In this paper, we improve the buffer scheme of Epidemi...

The buffer allocation problem (BAP) has been widely studied by researchers while pursuing diverse research goals. Similarly, the cross-entropy method has been applied to a variety of optimisation problems with single objectives. In this article it is extended to the multiobjective case and proposed as a computationally economic approach to optimise at least two conflicting objectives of the BAP...

Switch and router architectures employing a shared buffer are known to provide high throughput, low delay, and high memory utilization. Superior performance of a shared-memory switch compared to switches employing other buffer strategies can be achieved by carefully implementing a buffer-management scheme. A buffer-sharing policy should allow all of the output interfaces to have fair and robust...
