....tables Dispatcher Daemon Authentication and access lists services The next sub sections detail the role of the parts shown in figure 1. User space Kernel space Fig. 1. YAAP node architecture 2. 1 Packet transmission To insure interoperability with existing networks, YAAP uses direct ANEP [6] in IP encapsulation for the transmission of the active packets. ANEP has been implemented in kernel space along side IP to provide faster response time. We use for that purpose a new protocol code specifying the ANEP protocol in the IP header to demultiplex packets at the IP level. The format ....

....can be extended for this purpose. Anetd currently performs two major functions: 1) deployment, configuration, and control of networking software (in particular, EE prototypes) and (2) demultiplexing of active network packets (encapsulated using the Active Network Encapsulation Protocol or ANEP [2]) to multiple EEs located on the same network node. It allows multiple EE developers to independently manage different EEs simultaneously, using the underlying OS functions (e.g. Unix processes) to provide isolation. Anetd requires only minimal changes to current prototype EEs. An early Anetd ....
....authorities. 6 The UDP header specifies one of the well known active network ports; this header is strictly needed only to demultiplex to a particular virtual topology. The IP tunnel defined by the UDP encapsulation effectively provides a virtual link layer for active networking. The ANEP [2] header specifies the appropriate EE type. IP Compatibility Access Normal Internet packets may receive active processing. Such packets, which have the general format Link layer header IP header IP payload can be selected using a packet filter specifying some combination of these header ....

....or capsules and to control the processing. Significant research works include: the MIT ANTS (Active Node Transfer System [6] toolkit, the UPenn Switchware architecture [5] the Columbia University Netscript language [7] the USC ISI Abone (Active Backbone) 9] the Active Networks protocol ANEP [8] and the BBN Smart Packet network management [10] To date, these developments have been mainly realized in software based hosts (e.g. Linux systems) that offer the required programmability but lack the performance required in real networks. Nonetheless, the foremost goal of Active Networks is to ....

....performs two major functions: 1. Deployement. It allows the deployment, con guration and control of networking software, including current active networking execution environment (EE) prototypes, into the network. 2. Demultiplexing. It demultiplexes active network packets, encapsulated using ANEP [1], to multiple EEs located on the same network node and sharing the same input port. Anetd requires little or no change to either legacy networking software or current active networking prototypes and greatly improves the ability to manage large active networks. 1.1 Deployment Capability Anetd ....
....it uses a standard Unix API, it should be easily portable to any Unix platform. At the time of this writing, Anetd is available for FreeBSD on x86, Linux on x86 and Solaris on Sparc. This section remains to be written] 3 Usage Anetd listens on TCP and UDP ports (default 3322) and accepts ANEP [1] encapsulated packets. If the type ID in the ANEP packet header is of the type assigned to Anetd by ANANA (type 51) the ANEP payload is parsed and Anetd control commands are executed. A client application, called sc, allows the user to send commands to Anetd. The commands are signed using public ....

....with legacy systems and applications and (2) offering a generalized infrastructure for distributing and managing multiple kinds of distributed mobile applications. ANCORS offers an API for downloading and managing mobile code in a generic manner, using the Active Network Encapsulation Protocol [2] as its packet level interface. ANCORS s system management support, therefore, is not targeted to a single language or application but can be used to bootstrap a large class of mobile application. 5.2 Engineering Support A unique characteristic of the ANCORS architecture is that it integrates ....

....there has been considerable blurring of these roles and contributions as the work has evolved. One effort we have pursued with other members of the active network community is the design of an Active Network Encapsulation Protocol (ANEP) this has grown into perhaps the first active network RFC [2]. ANEP has been adopted and used in many of the active networks projects, and has allowed packet forwarding across the IP Internet. To achieve greater interoperability, however, we must provide more than a standard packet format; this, after all, is the essence of the Internet idea. What we must ....
