Overload control and performance evaluation in a Parlay/OSA environment

Andersson, Jens K LU (2004)
Abstract
To increase the pace of development and deployment of new services and

applications in telecommunication networks, new service architectures

have been proposed. Parlay/OSA is one of the proposals that has aroused

most attention. By providing network functionality via Application Program

Interfaces (APIs), Parlay/OSA facilitates creation of telecommunication

services and applications for independent software developers. With

Parlay/OSA there is no longer any requirement for knowledge and technical

skills of telecommunications when creating new applications. A Parlay/

OSA environment introduces gateways, which provide the

applications with abstracted network... (More)
To increase the pace of development and deployment of new services and

applications in telecommunication networks, new service architectures

have been proposed. Parlay/OSA is one of the proposals that has aroused

most attention. By providing network functionality via Application Program

Interfaces (APIs), Parlay/OSA facilitates creation of telecommunication

services and applications for independent software developers. With

Parlay/OSA there is no longer any requirement for knowledge and technical

skills of telecommunications when creating new applications. A Parlay/

OSA environment introduces gateways, which provide the

applications with abstracted network functionality. A gateway translates

the requests for abstracted functionality to telecommunication protocols

and signalling. Parlay/OSA is a contract driven architecture where several

constraints coexist. To fulfil the constraints and to protect the gateways

from shutting down, overload control mechanisms are needed.

This thesis proposes and evaluates different overload control mechanisms

in a Parlay/OSA environment. The main objectives of the overload

control mechanisms are to protect the system and to maintain a high

throughput. Important issues that are discussed are measurement strategies,

overload control actions, and how different priorities and time constraints

should be considered. Also, the proposed overload control

mechanisms consider some guiding principles from the specifications of

Parlay/OSA. In the scope of this thesis both distributed and single server

systems are investigated. (Less)
