Summary:We describe a framework for programming value-added services into
an edge router, such as a router used by a local enterprise domain for
access to external IP transport services. Service programming modules
and policies are downloaded from servers by CORBA object invocations
made by an operator to the programmable router. The programmable
functions include creation of virtual networks (VNs) providing selective
treatments to aggregated IP traffic classes defined according to
user(s), applications, or other classifications that can be determined
from the traffic itself. VNs may be mapped into a variety of external
transport services, including IntServ, DiffServ, or ATM services. We
illustrate these capabilities with two examples: a “guest
IP” service that provides a visiting portable IP device with
access to the Internet and specified local resources without requiring
any configuration changes in the portable device; and priority-ranked
VNs for traffic of Internet applications such as HTTP, FTP, Telnet and
RealAudio. These mechanisms have been implemented and verified in a
3-month trial with four guests, on a 233 MHz Pentium II/Linux platform
