Application-Level QoS: Improving Video Conferencing Quality Through Sending the Best Packet Next

Tags:
tcp - ip

Overview In a traditional network stack, data from an application is all transmitted in the order that it is received. This paper proposes an algorithm where information about the priority of packets and expiry times is used by the transport layer to reorder or discard packets to optimise the use of the network. This can be used for video conferencing to prioritise important data. This algorithm is implemented as in interface to the Datagram Congestion Control Protocol (DCCP) and compared to UDP and TCP using synthetic traffic modelled on common video conferencing applications. The results obtained show improvement can be made to video conferencing during periods of congestion.

Ipv6: An acronym to shake the networked world

That means IPv6 packets for transport over IPv4 routes must be packed separately. And for Windows 2000 there is already the beta version of an IPv6 stack. It ensures hackers cannot look at or change data packets.

Devil's Advocate: The internet traveller

In fact, another illustration of how difficult it is to suppress travel is the history of video conferencing. The latest claim is that heavy use of broadband in London will reduce travel, just in case Mayor Ken's congestion charging fails to do the...

Will congestion charging change the way we work?

Genesys Conferencing, for example, reckons demand for its services nearly doubled in Q3 2002 compared to the same period last year and attributes that in part to the ever-increasing pain and expense of commuting into London.

Peter Cochrane's Uncommon Sense: Circuit or packet, clean or dirty?

It is impossible to control the internet in the same way we control the telephone network and so congestion, collisions and traffic jams cause delays, bunching of packets in an unpredictable manner. The most successful attempts see the prescriptive...

Peter Cochrane's Uncommon Sense: Logistics on the move

The underlying bases of optimisation for linear systems, is to be able to optimise each individual component and then glue them together to realise an optima for the whole. So at a rough estimate we could take something between five and nine trucks...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
