Manageability of Future Internet

Technical Problems of the Internet (1/2)  Fundamental design principles of the current Internet  Collaboration  Trust  Use of intelligence at the edges to enable the core to be simple  Hard to map the current demands of users to services and resources that the network can offer (different domains)  Lack of security  Lack of mobility support  Interaction problems between the different layers (4)

Manageability of Future Internet Technical Problems of the Internet (2/2)  No guarantee on QoS – best effort service  Very difficult to manage due to explosive growth in # of devices & network traffic amount  There is no single standard for representing information that can be shared among heterogeneous applications and information sources (5)

Manageability of Future Internet Business Problems of the Internet  Each vendor uses different programming languages and models  Difficult to integrate data from devices from multiple vendors  It is becoming increasingly hard to make a profit  Unless the future network architecture takes competition and economic incentive, it is doomed to failure  New architecture has to be based on a sound economic model, not just a good technical one (6)

Manageability of Future Internet

Motivation for Future Internet  Need to resolve the challenges facing today’s Internet by rethinking the fundamental assumptions and design decisions underlying its current architecture  Three approaches 1.Incremental (non-evolutionary): a system is move from one state to another with incremental patches; new ideas that are not compatible with the original design are not allowed 2.Incremental (evolutionary): same as above, except new ideas that are not compatible with the original design are allowed 3.Clean-slate (revolutionary): redesigned from scratch to offer improved abstractions and/or performance, while providing similar functionality based on new core principles (8)

Manageability of Future Internet What is Future Internet?  Next Generation Network (NGN)?  a packet-based network to support the transfer of mixed traffic types such as voice, video, and data and to integrate services offered by traditional networks and new innovative IP into a single platform  Internet designed in accordance with either of the two incremental approaches  Future Internet?  Clean Slate design of the Internet’s architecture to satisfy the growing demands  Management issues of Future Internet also need to be considered from the stage of design  Research Goal for Future Internet  Performing research for Future Internet and designing new network architectures  Building an experimental facility (9)

We need not only evolutionary approach But also revolutionary approach We need not only evolutionary approach But also revolutionary approach FCAPS ? THINK about Manageability of Future Internet (14)

Manageability of Future Internet  Management Interface  Management Information Modeling & Operations  Complexity of management should be confined  The management plane should be independent of the data plane  Management Architecture  Centralized vs. Decentralized Management  Peer-to-Peer  Hybrid  Service Management  Customer-centric service  Service portability  SLA/QoS (15) Management Issues for FI (1/3)

Manageability of Future Internet  Traffic Monitoring/Measurement and Analysis  Monitoring for large-scale and high-speed networks  Network/application-level monitoring  Global traffic data access/sharing  Fast and real time monitoring  Statistical sampling method  Storing method for large scale traffic data  Measurement and analysis of social networking (16) Management Issues for FI (2/3)
