Vertical Paxos and Primary-Backup Replication

This paper introduces a class of Paxos algorithms called Vertical Paxos, in which reconfiguration can occur in the middle of reaching agreement on an individual state-machine command. Vertical Paxos algorithms use an auxiliary configuration master that facilitates agreement on reconfiguration. A special case of these algorithms leads to traditional primary-backup...

Buffer Management for Colored Packets With Deadlines

The paper considers buffer management of unit packets with deadlines for a multi-port device with reconfiguration overhead. The goal is to maximize the throughput of the device, i.e., the number of packets delivered by their deadline. For a single port or with free reconfiguration, the problem reduces to the well-known...

How to Improve the Efficiency of IPv6 Handovers in IEEE 802.16 Networks

The first generation of fully conformant IEEE 802.16-based networks is being deployed throughout the world. Most of these networks do not support full mobility, due to radio access layer limitations. Newer solutions, based on IEEE 802.16-2005 standard, offer mobility support for subscriber stations. Unfortunately, after quickly changing the point of...

Dynamic Updates of Graphical Components in the .NET Framework

Modern software has to operate in highly dynamic environments. In order to provide acceptable application-level quality-of-service parameters, applications must be adapted to underlying resource availabilities and other properties of their environment. Dynamic reconfiguration provides a powerful mechanism to realize these adaptations. Besides changes in the application structure and used algorithms,...
