....this model, an active node is composed of three main parts: CPU scheduler, Output scheduler and a feedback element (see Figure 11) We assume that all active packets that traverse the node carry code that needs to be executed by the CPU. On reception of a packet, the node performs several steps [3]: It first retrieves the packet from the network card. It enqueues the packet in the processing queue corresponding to its flow. The CPU scheduler (Input Scheduler) then chooses a packet to process from the input queues. After processing the packet, it inserts the packet in the output queue ....

Current approaches to active networking address this problem by introducing a trust relationship between the party which installs the software in the network and the owner of the network ( 3] 4] and [5]) The software is trusted by the network owner in the sense that its execution is assumed to consume no more than a certain amount of resources, and that its functions inside the network do not interfere with other network services. The difficulties with this approach are that (1) only few ....

....by routers as programs to be executed, rather than just data to be forwarded. More realistic variants of active networking involve the dynamic execution of trusted programs on behalf of individual application sessions, in response to signaling messages exchanged at the start of a session [4]. This work is oriented toward the latter view of programmable networks. However, it can also be applied in networks where the use of programmable elements is controlled by administratively determined policies, rather than user initiated signaling messages. To illustrate the potential of ....

....that it is very important to automatically deploy any type of application specific processing to routers (active networking) In this section, we will briefly describe our Active Router Plugins software architecture and its application to WaveVideo scaling. The architecture was introduced in [8] and [9] Routerplugins are code modules, which implement specific datagram processing functionality like encryption, congestion 1. At 155 Mbits s OC 3 speed a router can spend only 26 ts to receive, process, and forward a packet (assuming an average size of 500 bytes) clearly not long ....
