Resource allocation in a multiple-priority buffered link

In this paper we consider a multiple-priority buffered link, with a focus on resource allocation issues; our study was motivated by such issues in Carrier Ethernet, but the applicability of the results is by no means limited to this technology. In our model, the resource is shared by two priority classes. As the high-priority queue - intended...

Ethernet Operation Administration and Maintenance ; Opportunities for the NREN community

Ethernet started its life as a Local Area Network technology and initially did not have Operations, Administration and Maintenance (OAM) features like IP Ping, IP Traceroute and SDH Loss of Frame. Monitoring and management was mainly done on the IP level. In the case of delivery of Ethernet connections or services IP OAM traffic could follow a...

Design issues of a back-pressure-based congestion control mechanism

Congestion control in packet-based networks is often realized by feedback protocols - in this paper we assess the performance under a back-pressure mechanism that has been proposed and standardized for Ethernet metropolitan networks. Relying on our earlier results for feedback fluid queues, we derive explicit expressions for the key performance...

A feedback fluid queue with two congestion control thresholds

Feedback fluid queues play an important role in modeling congestion control mechanisms for packet networks. In this paper we present and analyze a fluid queue with a feedback-based traffic rate adaptation scheme which uses two thresholds. The higher threshold B 1 is used to signal the beginning of congestion while the lower threshold B 2 signals...

Flow level performance approximations for elastic traffic integrated with prioritized stream traffic

Almost all traffic in todays networks can be classified as being either stream or elastic. The support of these two traffic types is possible either with a Differentiated (DiffServ) or an Integrated Services (IntServ) architecture. However, both DiffServ and IntServ rely on efficient scheduling mechanisms and traffic control to meet the...
