Smart Packets

As part of the DARPA Active Nets program, BBN is developing a capability for packets to carry programs which are executed at each node the packet visits in the network. The programs implement extended diagnostic fuctionality in the network. To do this, BBN is developing a special language for programming Smart Packets called Sprocket.

A complete Sprocket program will be encoded in either a single IPv4 or IPv6 datagram. Our goal is to fit an interesting program in an Ethernet-sized packet, which requires a very compact representation. Furthermore, the program will be authenticated before intrepretation and run-time limited during execution.
