Pre-congestion notification (PCN) provides feedback about load conditions in a network to
its boundary nodes. The PCN working group of the IETF discusses the use of PCN to …

This work focuses on capacity overprovisioning (CO) as an alternative to admission control
(AC) to implement quality of service (QoS) in packet-switched communication networks. CO …

This work is subdivided into two main areas: resilient admission control and resilient routing.
The work gives an overview of the state of the art of quality of service mechanisms in …

Overload in a packet-based network can be prevented by admitting or blocking new flows
depending on its load conditions. However, overload can occur in spite of admission control …

Precongestion notification (PCN) is a packet-marking technique for IP networks to notify
egress nodes of a so-called PCN domain whether the traffic rate on some links exceeds …

This paper presents a mechanism for active resource management (ARM) in a differentiated
services environment. While the differentiated services architecture and the bandwidth …

Pre-Congestion Notification (PCN) in IP networks uses packet metering and marking within
a PCN domain to notify its egress nodes whether link-specific admissible or supportable rate …

Pre-congestion notification (PCN) marks packets when the PCN traffic rate exceeds an
admissible link rate and this marking information is used as feedback from the network to …

We introduce the notion of link and network admission control (LAC, NAC) and present three
fundamentally different budget based NAC methods which categorize most of today's …

This paper presents a mechanism for active resource management (ARM) in a differentiated
