Secure quality of service handling: SQoSH [PDF]

open access: yesIEEE Communications Magazine, 2000
Proposals for programmable network infrastructures, such as active networks and open signaling, provide programmers with access to network resources and data structures. The motivation for providing these interfaces is accelerated introduction of new services, but exposure of the interfaces introduces many new security risks.
