2 인터넷의성공 인터넷은인류최대의발명이다. 어느기술도이만큼인류에게큰영향을미치지못했다. 2

3 인터넷등장배경 미국방성의요구 : 많은통신시설이파괴되더라도계속살아남는통신네트워크를고안할것. 다양한통신기술을활용할수있을것 과학기술계의결론 패킷 (packet) 방식의통신네트워크 연결을만들지않음 전체의 70% 이상이파괴되어도계속생존하여통신기능유지함 3

36 Integrated Architecture Core network architecture Access network architecture Service architecture Management architecture Expecting many competing candidates 36

37 Network Testbed How to design and operate testbeds with massive number of users? Virtualization? Many tests in one testbed network Or separate network for each experiment? Global collaboration schemes US, Europe, Asia Network monitoring and measurement Troubleshooting and repair 37

38 Optical Transport Optical transport 기술의비약적발전 Unlimited bandwidth Dynamic switching Low cost Circuit, burst, packet switching 이경합중임 Optical storage 구현의어려움으로 packet 방식이제일불리함 GENI 에서는 dynamic circuit switching 채택이유망함 38

39 Storage-centric Networking Resources in networks Bandwidth CPU power Memory : 지금까지거의고려하지않았음 Users want data (content) ( 방법 1)Data 가있는 location 에연결하고, data 를가져옴 ( 방법 2)Data 를찾는 query 를뿌리고응답이오길기다림 모든 network node 에지나가는모든 data 를 store 함 ( 대용량 memory) 39

40 Multicast/Broadcast 미래의 network 은주로 multicast traffic 을운반할것임 Network architecture/protocol 을변경해야 Core network-access network 에서다른접근필요 Wireless access 에서 multicast solution 필요 40

41 Issues in Location Context Accuracy Indoor Context 3D 좌표 방향 인접노드 응용과의결합 Geographic addressing Geographic routing Security, privacy 41

42 Multi-networks 미래네트워크환경에서단말기는동시에여러네트워크과연결을유지할것임 예 : wireless access : cellular, WiFi, WiBro 예 : core : optical backbone, Mesh Backbone Which network/interface to use for data transfer? Uplink, downlink Load balancing, backup Handoff between interfaces What about mobility? 42

43 Network Monitoring 현재의 Internet 에서네트워크의성능측정, 고장감지가매우어려움 New network monitoring, measurement architecture is required To understand the network behavior To see the network status (traffic, performance) To locate the faulty resources (HW, SW) Micro-level, macro-level 43

46 미래의환경 네트워크의다양화 단말기의다양화 응용의다양화 컴퓨팅기술에더욱의존 컴퓨팅원천기술을보유한기업이시장주도예상 Apple, HP, Google 미래인터넷기술개발에높은관심을가짐 46

47 Focus Japan : vehicle + Internet Europe : mobile terminal + applications US : backbone + everything above KOREA :??? Mobile devices + applications + cellular net Robots (networked) : Internet café >> screen golf >> robot-assisted life 47
