An efficient buffer management methods for Cachet
(cont.) running simulation. Third, since BCachet is almost linear under the assumption of a reasonable number of sites, BCachet is very scalable. Therefore, it can be used to for very large scale multiprocessor systems.

Joint buffer management and scheduling for input queued switches
… IQ switches. However, they do not consider the buffer space requirement inside an IQ switch that may render the scheduling algorithms inefficient in practical applications. In this dissertation, the Queue Length Proportional (QLP) algorithm is proposed for IQ switches. QLP considers both the …

Competitive prefetching and buffer management for parallel I/O systems
In this thesis we study prefetching and buffer management algorithms for parallel I/O systems. Two models of lookahead, global and local, which give limited information regarding future accesses are introduced. Two configurations of the I/O buffer, shared and distributed, are considered, based upon …

Buffer management and cell switching management in wireless packet communications
The buffer management and the cell switching (e.g., packet handoff) management using buffer management scheme are studied in Wireless Packet Communications. First, a throughput improvement method for multi-class services is proposed in Wireless Packet System. Efficient traffic management schemes …

An investigation into buffer management mechanisms for the Diffserv assured forwarding traffic class
… that microflow and aggregate-unaware active buffer management mechanisms such as RIO (Random early detecLion with ln/Out-ofprofile) be used in the core of Diffserv networks implementing AF. Such mechanisms have, however, been shown to provide poor performance with regard to fairness, …

Performance evaluation of database management systems
… accesses when accessing a file randomly with buffering. We present the layered hot set model which quantifies the locality of page references when executing a query using a DBMS. We presented the ABLE buffer management algorithms for DBMS's. We give cost models for both relational DBMS's and …

Quality of service optimization of multimedia traffic in mobile networks
… in the base stations, necessitating buffering of data at the air interface which presents a bottleneck to end-to-end communication. Hence, in order to provide end-to-end Quality of Service (QoS) guarantees to multimedia services in wireless networks such as HSDPA, efficient buffer …

Process developments and critical design attributes in buffer systems for the biopharmaceutical industry
… in this thesis addresses biopharmaceutical buffer management, which has historically received limited attention despite accounting for approximately 20% of the cost of manufacture. Traditional approaches have persisted, resulting in operational bottlenecks, inflexible facility designs, and …

Scalable video transportation using look ahead scheduling
… the study proposes a scheduling algorithm and buffering technique. To combat the variation of delay (jitter) in a best-effort network, the study proposes Look Ahead Scheduling Algorithm (LASA) which provides unequal look-ahead by safeguarding the base layer of the scalable video. The results of …

A study and analysis of a transmission scheduling and discard algorithm for ATM networks
… can be divided into three separate policies: buffer management policy, transmission po1icy, and discard policy. The buffer management policy is presented by previous publications, thus not analyzed in this research. The objective of the transmission policy is to minimize the conflicting goals …

Interpreting and applying demand driven MRP: a case study
… – DDMRP is shown to embody the concepts of buffer aggregation and buffer management within the context of dependent demand planning, effectively integrating MRP and TOC. The underlying production planning and control issues of the company were found to be consistent with the literature …

A Data Layout Descriptor Language (LADEL).
… standard C block I/O interfaces use block buffers of type char. C++ programs that perform block I/O commonly use typecasting to move data between structures and block buffers. The subject of this thesis, the layout description language (LADEL), represents a high-level solution to the …
