Building an adaptive Web server with a meta-architecture: AISF approach

As the Web is becoming ubiquitous environment, Web servers are faced with a diversity of requirements. This paper addresses how Web servers can meet a wide range of requirements, and proposes an adaptive framework called AISF (Adaptive Internet Server Framework) which employs a meta-architecture to make the Web server adaptable and con gurable. We are interested in applying the meta-architecture to Web servers, where it has had little acceptance to date. AISF provides a set of ne-grained metaobjects which capture and express various aspects in Web servers. Web servers can dynamically adjust itself to meet any requirement by implementing it within the AISF programmable meta model. This paper also demonstrates that AISF can be used to meet every demand placed upon Web server consistently, and includes some proof-of-concept examples. Our approach aims to create adaptive Web servers beyond a static and monolithic servers.
