Disebabkan pembangunan yang mendadak, permintaan capaian Internet menjadi kian popular di mana-mana saja melalui pelbagai jenis media, Over a span of thirty five years, the Internet has developed and grown rapidly. Due to its rapid growth, the demand for Internet access today is everywhere and over every possible medium such as satellite communications

Robust Header Compression (ROHC) in Next-Generation Network Processors

Robust Header Compression (ROHC) provides for more efficient use of radio links for wireless communication in a packet switched network. Due to its potential advantages in the wireless access area andthe proliferation of network processors in access infrastructure, there exists a need to understand the resource requirements and architectural implications of implementing ROHC in this environment. We presentan analysis of the primary functional blocks of ROHC and extract the architectural implications on next-generation network processor design for wireless access. The discussion focuses on memory space andbandwidth dimensioning as well as processing resource budgets. We conclude with an examination of resource consumption and potential performance gains achievable by offloading computationally intensiveROHC functions to application specific hardware assists. We explore the design tradeoffs for hardware as-sists in the form of reconfigurable hardware, Application-Specific Instruction-set Processors (ASIPs), andApplication-Specific Integrated Circuits (ASICs)

A Survey of Bandwidth Optimization Techniques and Patterns in VoIP Services and Applications

This article surveys the various techniques adopted for optimising bandwidth for VoIP services over the period 1999-2014. The improvement of bandwidth can be realized through; silence suppression measure of repressing the silent portions (packets) in a voice conversation using Voice Activity Detection algorithm; by so doing, the transmission rate during the inactive periods of speech is reduced, and thus, the mean transmission rate can be reduced. A second measure is packet header reduction which defines a process of multiplexing and de-multiplexing packet headers to curb excesses. Voice/ Packet Header compression is considered the most productive of all the techniques, offering a scheme where VoIP packets are compressed from the 40 bytes of size to a smaller byte size of 2 bytes. When combined with aggregation, compression potentially yields a compressed size of up to 1 byte. In either case, bandwidth save is reached using compression and decompression codecs of varying data and bit rates. It is envisaged that an improvement in the performance of codecs would yield a better result in terms of enhancing results favourably in Voice over broadband networksComment: 8 pages, 7 figures.

Aplicación de métodos de compresión de cabeceras TCP/IP como optimización de las comunicaciones móviles

El protocolo TCP (Transmission Control Protocol) está implementado para actuar en redes fija s, donde las incidencias en la comunicación pueden interpreta rse como problemas de con ges tión. En entornos móviles, en cambio, los problemas son debidos a una alta tasa de error en bit (BER); la utilización del protocolo TCP en este tipo de entornos afecta negativamente a la efici encia de la transmisión. En este artíc ulo se presenta una solución pa ra optimizar la comunicación TCP: la compresión de cabeceras; concretamente se expone la necesidad de un algoritmo especifico para comunicaciones móviles y se valora la propuesta de compresión de cabeceras de la lETF .Peer Reviewe
