Internet traffic is growing exponentially, and different kinds of traffic a
re being integrated into the Internet Protocol. To keep up with these chang
es, the Operation Support System (IP-OSS) will be changed to adapt a divers
ification of IP services. In this paper, after describing the framework of
a future IP-OSS, we discuss "negotiation," which will become a key function
in future IP management. We describe a policy/negotiation-based IP managem
ent service for an enterprise network. This service realizes end-to-end pol
icy-based enterprise networking. Lastly, we introduce some Fujitsu IP-OSS p
roducts for supporting these features.
