QoS measurement and management for Internet real-time multimedia services (2003)

Jiang, Wenyu

In recent years real-time multimedia services have become increasingly popular over the Internet, in particular voice over IP (VoIP). Nevertheless, several issues remain outstanding before the wide...

Towards Junking the PBX: Deploying IP Telephony (2001)

Wenyu Jiang, Jonathan Lennox, Henning Schulzrinne, Kundan Singh

Modeling of Packet Loss and Delay and Their Effect on Real-Time Multimedia Service Quality (2000)

Wenyu Jiang, Henning Schulzrinne

Internet packet loss and delay exhibits temporal dependency. If packet n is lost, packet n + 1 is also likely to be lost. It leads to bursty network losses and late losses in real-time multimedia...

Detecting And Measuring Asymmetric Links In An IP Network (2000)

Wenyu Jiang, Timothy F. Williams

The rapid growth of Internet tra#c has made it important to pinpoint network bottlenecks. Measuring link bandwidths can help identifying such bottlenecks. Existing bandwidth measurement tools such as...

QoS Measurement of Internet Real-Time Multimedia Services (1999)

Wenyu Jiang, Henning Schulzrinne

Real-time applications such as IP telephony, Internet radio stations and video conferencing tools require certain levels of QoS (Quality of Service). Because the Internet is still a best-effort...

QoS Measurement of Internet Real-Time Multimedia Services (1999)

Wenyu Jiang, Henning Schulzrinne

this paper, we are mainly concerned with the measurment and modeling of network delays.

An Architecture for WWW-based Hypercode Environments (1999)

Gail E. Kaiser, Stephen E. Dossick, Wenyu Jiang, Jack Jingshuang Yang
