Load Balancing and Admission Control of a Parlay X Application Server
Author
Summary, in English
To increase the number of services and applications in the telecommunication networks a new
service architecture has been proposed and specified. The consortia that initiated the new
service architecture is called Parlay. Since then, there has been a continued development and
3GPP the standardization group for 3G networks, is now cooperating with Parlay. 3GPP and
Parlay are together specifying the Parlay/OSA standard.
However, the aim with the new service architecture is to make the art of service
development so easy that any software developer should be a potential application developer
for telecommunication networks. It is foreseen to be a dramatic increase of new services, but
it has been shown that it is still complex to create new applications. Parlay X is a standard
which is an extension of Parlay/OSA, initiated to allow access to the telecommunication
network capabilities via web services. The Parlay X architectures include an Application
Server (AS), which translates the web service calls to Parlay/OSA commands. A typical AS is
a distributed environment sensitive to overload.
In this paper we propose and investigate an overload control mechanisms for an AS. The
methods have been implemented in a real AS to evaluate the performance. Parlay X is a
contract driven architecture, where different service providers have different constraints about
minimum number of service calls served per second and maximal delays of different services.
The methods and algorithms are designed to serve different service providers with different
contract parameters.
