Future multiservice networks will be multifractal, and thus impossible to control accurately using conventional finite-state-machine models. Active networking can reduce the cost to operators by delegating management to network users, but this will increase the overall system complexity. Management architectures for active networks must therefore use a new approach. An open-ended alternative to...

With the increasing share of renewable and distributed generation in electrical distribution systems, Active Network Management (ANM) has become a valuable option for a distribution system operator to operate his system in a secure and cost-effective way without relying solely on network reinforcement. ANM strategies are short-term policies that control the power injected by generators and/or t...

Active Networks are a network infrastructure which is programmable on a per-user or even per-packet basis. Increasing the flexibility of such network infrastructures invites new security risks. Coping with these security risks represents the most fundamental contribution of Active Network research. The security concerns can be divided into those which affect the network as a whole and those whi...

This paper explores achieving “application/network adaptation” in wide-area networks supporting mobile users through the use of an active network technology. Network flexibility is achieved through the introduction of SmartPackets which carry address information, user data, and user-specified methods that act on the SmartPacket as it traverses the network. Thus, SmartPackets allow the applicati...

Abstract: Active network tomography includes several interesting statistical inverse problems that arise in the context of computer and communication networks. The primary goal in these problems is to recover link-level information about quality-of-service parameters from aggregate end-to-end data measured on paths across the network. The estimation and monitoring of these parameters are of con...

This section describes an approach for representing and propagating contraints in active database systems during product development. In this context, constraints are used for consistency checks of product models in databases as well as for the support of designers in product development. Concepts of active database systems are examined to represent and evaluate dependencies specified by design...

Resource management in active network nodes is challenging because more types and amount of resources are needed compared with traditional networks, and the consumption of different types of resources is not equally balanced. Hence, it is possible and important to consider the relationship between different types of resources needed by an application. Adaptation of applications’ resource usages...
