TFMC: A TCP-Friendly Multiplexing Control Scheme for VoIP Flow Transmission

Tags:
voip - ip telephony

Overview This paper investigates the performance limitations in the case of a large number of long distance voice over IP calls originating from different sources and transported through a best-effort IP network. The paper focuses on the potentially negative effects of protocol header overhead, which is twice the voice payload generated by the high-compression audio codecs. These negative effects range from the inefficient use of bandwidth to the network congestion caused by the large number of short voice packets flowing into the IP network, which degrades the real-time transmission performance and creates a fairness problem because of TCP traffic being suppressed.

MPLS: The icing on the networking cake?

If all packets are sent using IP, the shortest points between popular destinations can become bottlenecks making the possibility of providing time-delay sensitive services - such as video or voice - difficult.

Comment & Analysis

Managing convergence - the key points every company should know about

It is possible to avoid some of these problems by using strict policy management and most current routers come with quality of service (QoS) features that allow businesses to prioritise voice and video packets.

What are IP VPNs good for?

Because IPSec encrypts data before forwarding it over the IP VPN and then decrypting it, there's a delay that makes using these apps together tough, and practically prohibits voice packets. Premium IP VPN service is provided over a private IP...

Secure VoIP has arrived

For one, they rely on TCP (Transmission Control Protocol), which works well for data applications but not as well for latency-sensitive traffic such as voice. TCP uses packet retransmission, which means that packets can be delayed en route to their...

VoIP primer: How it works - and what the jargon means

Just as a web page can be broken up into 'packets', audio can be sampled with a digital signal processor (DSP), 'packetised' and sent out over an IP-based network as another data stream. The packets that make up the audio stream may take different...

Peter Cochrane's Blog: Fat cat telcos are killing the net

Unfortunately, the dark side has never been able to grasp this opportunity for change as they are locked into 100-year-old mindsets, where time, distance and bandwidth are chargeable items. Yes, it all works to some degree some of the time but...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
