....run these external programs using local computational resources. An important service offered by active networking is the VAN provisioning. A VAN can be described as a graph of virtual active nodes connected by virtual links where active packets can travel within a VAN or between different VANs [2]. A VAN can be only created using nodes of the same domain and every user must belong to some VAN. A VAN is a kind of VPN implemented using AN technology. The VAN concept is a very useful solution to isolate groups of customers and offer specific services to each customer s domain. While a VAN is ....

From the service point of view, active networking allows customized packet processing inside the network on a per packet, per flow, or per service basis.

Customized packet processing can be applied, e.g. to application aware routing, information caching, multi party communications, and packet filtering [1] From the management perspective, active networking technology enables rapid service deployment and flexible service management [2]. The paradigm of active networking allows a party to install and run a service on a network in a similar way as a program can be installed and executed on a computer. In this analogy, the network plays the role of the computer, which is simultaneously shared among many parties, i.e. customers, ....

....and a provider can be realized in a flexible way with respect to service abstractions and control capabilities for the customer in the provider s domain and vice versa. In the following, we outline our framework for interaction in an active networking environment, which we have first proposed in [2]. Figure 1 shows the interaction between a customer domain and a provider domain for service provisioning, service delivery and service management in our framework. We propose that the provisioning of a specific (active) network service X is split into two different operations: the ....

....Abstract Active networking, where network nodes perform customized processing of packets, is a rapidly expanding field of research. This paper investigates the realization of service management on a Virtual Active Network (VAN) the key concept in our active network management framework [11]. A VAN can be seen as a thin (software) layer in an active networking environment, which creates a generic service abstraction, offered by the provider to the customer. The VAN concept transforms a multi domain situation into a single domain for a customer. The customer can install, run and ....

Active networks transport active packets [2] also called capsules in [19] Active packets contain programs or pointers to program modules, in addition to data. A network node executes such a program, which possibly modifies the node s state and possibly generates further active packets to be ....

This paper investigates the realization of service management on a Virtual Active Network (VAN) the key concept in our management framework for active networks [1]. A VAN is a generic service offered by the VAN provider to the customer. The VAN abstraction transforms a multidomain environment into a single domain view for a customer.

....with active packets, the task of service management changes from managing a static, well defined service to managing a dynamic, customized service. The interfaces between customers and providers in an active networking environment are changed from being service specific to be truly generic (see [1] and Section 2) The generic service interface is enabled by the concept of active packets, which allows a customer to access a service in the provider domain as well as to perform service management operations related to the installation, supervision, upgrading and removal of a specific service. ....
