Abstract A Service Middleware that Scales in System Size and Applications (2008)

Constantin Adam, Rolf Stadler, Chunqiang Tang, Malgorzata Steinder, Michael Spreitzer

We present a peer-to-peer service management middleware that dynamically allocates system resources to a large set of applications. The system achieves scalability in number of nodes (1000s or more)...

Distributed Resource Allocation Strategies for Achieving Quality of Service (2008)

Björn Johansson, Constantin Adam, Mikael Johansson, Rolf Stadler

Abstract — We investigate the resource allocation problem for large-scale server clusters with quality-of-service objectives, where key functions are decentralized. Specifically, the optimal...

Submitted to IEEE electronic Transactions on Network and Service Management (eTNSM) (2008)

Koon-seng Lim, Constantin Adam, Student Members, Rolf Stadler

Abstract — We argue that effective management of future large and dynamic networks must be based on adaptive, decentralized control, in order to overcome the drawbacks of today’s management...

A Service Middleware that Scales (2008)

Constantin Adam, Erik Häggbrink, Rolf Stadler

We have implemented our middleware in Java, as an application filter in the Tomcat environment [1] (see Fig. 1). The filter instantiates when the Tomcat server starts the application(s) associated...

Describe some real enterprise middleware Identify distributed systems problems, technologies in that middleware There is much more to it than messaging It is not all based on group communication...

ELECTRONIC TRANSACTIONS ON NETWORK AND SERVICE MANAGEMENT (ETNSM), VOL., NO., 1 A Middleware Design for Large-scale Clusters Offering Multiple Services (2008)

Constantin Adam, Student Member, Rolf Stadler

Abstract — We present a decentralized design that dynamically allocates resources to multiple services inside a global server cluster. The design supports QoS objectives (maximum response time and...

A Middleware for Self-Managing Large-Scale Systems} (2006)

Adam, Constantin

This thesis investigates designs that enable individual components of a distributed system to work together and coordinate their actions towards a common goal. While the basic motivation for our...

Constantin Adam, Giovanni Pacifici, Michael Spreitzer, Rolf Stadler, Chunqiang Tang

Abstract. This paper addresses the problem of dynamic system reconfiguration and resource sharing for a set of applications in large-scale services environments. It presents a decentralized...

A Middleware for Self-Managing Large-Scale Systems (2006)

Constantin Adam, Student Member, Rolf Stadler

Abstract — Resource management poses particular challenges in large-scale systems, such as server clusters that simultaneously process requests from a large number of clients. A resource management...

Generic Management and Control API Based on an Object-Level Interaction Paradigm and Its Demonstration in a Virtual Workshop Service (1998)

Lazar, Aurel L., Stadler, Rolf, Adam, Constantin, Aurrecoechea, Cristina, Borla, Marco

The goal of this work was to define generic application programming interfaces (APIs) for the control and management of an ATM-based telecom environment. In our approach the APIs are defined, based...
