Lifetime Packet Discard for Efficient Real-Time Transport Over Cellular Links

Tags:

Overview Mobile cellular users often experience significant delay jitter that undermines quality of real-time applications. Delay jitter can cause unnecessary delivery of stale packets with passed playback deadline and duplicate packets retransmitted by the end host after experiencing a timeout. With Lifetime Packet Discard (LPD) a flow adaptive link can tailor the trade-off between the maximum delay jitter and reliability if quality of service requirements of a flow are known. This paper proposes using an IP option to communicate the flow requirements to the link layer.

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. Those that 'tunnel' across the public internet rely on...

Your perimeters are "porous", companies told

Deperimeterisation - where the security emphasis is moved from the edge of the network and onto individual devices, and ultimately to individually encrypted data packets - became a fact for ICI with increasing employee mobility, Simmonds argued.

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

The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications. Any 'latency' - the delay in delivering the voice stream from the speaker to the listener - degrades the quality of...

Cisco tightens VoIP security

Like other packet-based applications, voice networks can suffer from denial-of-service attacks, which are caused when a hacker floods a network with packets until the switches and routers directing traffic throughout the network are frozen.
