Towards Plug-and-Play Services: Design and Validation Using Roles
(Dr. ingeniøravhandling, 0809-103X; 2003:47, Doctoral thesis, 2003)Today telecommunication service users expect to access a similar set of services independently of what network they happen to use, they expect services to adapt to new surroundings and contexts as they move around, and ... -
Performance measurements in packet-switched networks : application to IP networks
(Doktoravhandlinger ved NTNU, 1503-8181; 2002:142, Doctoral thesis, 2003)The Internet is becoming an important infrastructure. Measurements of network traffic are vital for many areas; including network management, traffic engineering, service differentiation, accounting and billing, the design ... -
Nested loop radio frequency synthesizers
(Dr. ingeniøravhandling; 2003:19, Doctoral thesis, 2003)This thesis describes how PLL frequency synthesizers with cascaded and nested loop topologies can be used for the synthesis of low noise high frequency signals. Briefly explained, synthesizers with cascaded/nested loops ... -
Emergent behavior based implements for distributed network management
(Dr.ingeniøravhandling, 0809-103X; 0806-103X, Doctoral thesis, 2003)Network and system management has always been of concern for telecommunication and computer system operators. The need for standardization was recognised already 20 years ago, hence several standards for network management ... -
Is BS 7799 worth the effort?
(Master thesis, 2004)NORSK: Denne masteroppgaven fokuserer på hvorvidt organisasjoner som har sertifisert sitt styringssystem for informasjonssikkerhet etter BS 7799, oppnår en bedre evne til å forebygge, detektere og reagere på sikkerhetsbrudd ... -
A process for Security Metrics Program (SMP)
(Master thesis, 2004)NORSK: Tjenesteleverandører har ofte mange nettverk koblet sammen i komplekse arkitekturer. Denne arkitekturen er i stadig endring, det kan være grunnet endringer som må gjøres pga tekniske løsninger, eller for at noen ... -
Passport of the Future: Biometrics against Identity Theft?
(Master thesis, 2004)NORSK: Formålet med biometriske pass er å forhindre ulovlig adgang av reisende inn i et land og å begrense bruken av forfalskede reisedokumenter ved en mer nøyaktig autentisering av reisende. Etter den 11. september ... -
Network layer packet redundancy in optical packet switched networks
(Journal article; Peer reviewed, 2004)A crucial issue in optical packet switched (OPS) networks is packet losses at the network layer caused by contentions. This paper presents the network layer packet redundancy scheme (NLPRS), which is a novel approach to ... -
