Outline

• Simula Research Laboratory

• Network and Distributed System Department (ND)

• Resilient Network (RN) Project

• Why build Simula?– Norway build a new

airport and hope to re-use the old airport in Fornebu

– Various proposals to usethe airport

• Build High-Tech Park withNational Funded ResearchLaboratory

• Research Council (2000)– Selection of activities

• Certain expectations– High quality research– Education (PhD)– Industrial relations

St. prp. nr. 1 1999-2000, KUF (likelydende NHD og SD)

”…… en forutsetning for at et IT- og kunnskapsenterpå Fornebu skal bli vellykket, er at det etableres et Center of Excellence (Senter for fremragende forskning jf. St. meld. nr 39 (1998-99) Forskning ved et tidsskille) innen for informasjons- og kommunikasjonsteknologi. …… …………Regjeringen foreslår at det i 2000 totalt bevilges 45 mill. kroner til etablering av et Center ofExcellence på Fornebu. Etableringen vil være en samfinansiering av Kirke-, utdannings- og forskningsdepartementet (30 mill. kroner), Nærings- og handelsdepartementet (10 mill. kroner jf. kap. 920) og Samferdselsdepartementet (5 mill. kroner jf. kap. 1301). Norges forskningsråd vil få det koordinerende ansvaret i planleggingen, men dette vil skje samarbeid med forsknings- og utdanningsinstitusjonene.”

Simula – the name

• Ole Johan Dahl and Kristen Nygaard– Turing award in 2001. “For

ideas fundamental to the emergence of object-oriented programming, through their design of the programming languages Simula I and Simula67.”

• Simula – Programming language to realize object-orientation

• Produced 6 Ph. D.s plus recent 5 in 2007

11

ND Projects• Resilient Networks (RN)

– Resilience in wired and wireless networks– Cooperation with Telenor, and universities in Europe.– Financed by the Ministry of Transport and Communication, Norway

• RELAY– Resource usage in Large scale Distributed Systems. – Cooperation with Funcom and Fast in addition to academic partners in

Europe.

• ICON – Sub-IP technologies, in particular Storage Area- and System Area

Networks– Cooperation with Sun Microsystems and Dolphin in addition to

numerous academic institutions in Europe and USA.

14

Resilient Networks 2006-2010• Five year funding from the Ministry of Transport and Communication,

Norway.

• Total funding of 27 MNOK

• WP1 ”IP-routing”– Fast reroute mechanisms– Post-Failure Traffic Load Balancing– Ad Hoc Network Resilience– Two INFOCOM papers (INFOCOM2006, INFOCOM2007)

• WP2 “Wireless IP-networks”– This activity started in August 2006 (lead by Dr. Yan Zhang (Josh) )

15

Resilient Wireless Network

• The purpose is to design architecture, protocols and algorithms to provide resilient services continuously and effectively for wireless networks. We are expecting to incorporate resilience as an inherent characteristic in wireless networks.

16

Understanding “Resilience” (I)

• Post-failure stage– Handle the emergence situation

– Spectrum handoff with primary system appearance

– If Node 3 is failed, Node 1 is isolated. Mechanism to make Node 1 communicate with other nodes.

17

Understanding “Resilience” (II)

• Before-failure: avoiding failure enhances the resilience – Energy management

– Mobility management

– Resource management

– Security management

– Spectrum management

– QoS

18

Wireless Systems/Networks

– Resilient Cognitive Mesh Networks• Resilient wireless mesh networks (WMN)• Resilient WiMAX Mesh Networks

– Resilient wireless sensor networks (WSN)

– And more (depending on manpower availability and progress)
