Transcript of "ITS 2010 - Extended presentation slides"

  1. 1. A First Glance Comparison of Next and New Generation Network Approaches Antônio M. Alberti (INATEL) Tania R. Tronco (CPqD) Christian E. Rothenberg (CPqD & Unicamp) ITS 2010
  2. 2. Motivation <ul><li>Current Scenario (1/3) </li></ul><ul><ul><li>The Internet became a vital part of today economy, society and institutions infrastructure. </li></ul></ul><ul><ul><li>However, requirements for the Internet have changed considerably since its conception . </li></ul></ul><ul><ul><li>Despite its huge success, Internet lacks on : </li></ul></ul><ul><ul><ul><li>Convergent multimedia experience for their users; </li></ul></ul></ul><ul><ul><ul><li>Improved support for mobility and unfettered service access; </li></ul></ul></ul><ul><ul><ul><li>Improved support for security, privacy, QoS; </li></ul></ul></ul><ul><ul><ul><li>Improved network attachment and service control. </li></ul></ul></ul>A First Glance Comparison of NxGN & NwGN
  3. 3. Motivation <ul><li>Current Scenario (2/3) </li></ul><ul><ul><li>Unsatisfied with such limitations, telecommunication operators standardized Next Generation Networks (NGN or NxGN) . E.g.: </li></ul></ul><ul><ul><ul><li>IMS ( IP Multimedia Subsystem) from 3GPP. </li></ul></ul></ul><ul><ul><ul><li>NGN-GSI ( Next Generation Networks Global Standards Initiative) from ITU-T. </li></ul></ul></ul><ul><ul><li>Despite the promises behind SIP/UDP/TCP/IP convergent networks, many researches started to ask if they are ready to support: </li></ul></ul><ul><ul><ul><li>A multimedia global information infrastructure ? </li></ul></ul></ul><ul><ul><ul><li>The tremendous increasing of new applications traffic? </li></ul></ul></ul><ul><ul><ul><li>The drastically increasing in the number of nodes/networks/applications? </li></ul></ul></ul><ul><ul><ul><li>New 3D and immersive applications? </li></ul></ul></ul><ul><ul><ul><li>Rich e-media and content distribution? </li></ul></ul></ul>A First Glance Comparison of NxGN & NwGN
  4. 4. Motivation <ul><li>Current Scenario (3/3) </li></ul><ul><ul><li>The Internet and NGN limitations and uncertainties motivated what is being called Future Internet Design or New Generation Network (NwGN). </li></ul></ul><ul><ul><li>Many research initiatives started to reinvent or rethink Internet, so it can fully assume the role we are assigning to it . E.g.: </li></ul></ul><ul><ul><ul><li>Japanese project Akari ; </li></ul></ul></ul><ul><ul><ul><li>European Future Internet Assembly initiatives ; </li></ul></ul></ul><ul><ul><ul><li>U.S. National Science Foundation Future Internet Design (FIND). </li></ul></ul></ul><ul><ul><li>This paper provides a first glance comparison between key aspects of NxGN and NwGN proposals. </li></ul></ul>A First Glance Comparison of NxGN & NwGN
  5. 5. Next Generation Networks <ul><li>At the heart of the NGN, sits 3GPP´s original IMS , which was embraced by ETSI and ITU-T as the common control architecture. </li></ul>A First Glance Comparison of NxGN & NwGN
  6. 6. Next Generation Networks <ul><li>ITU-T NGN-GSI architecture was standardized in Recommendation Y.2012, “Functional Requirements and architecture of the NGN”. </li></ul>A First Glance Comparison of NxGN & NwGN NGN – ITU-T Standard. Source: Y.2012.
  7. 7. Next Generation Networks <ul><li>Main features of NGN-GSI (1/3): </li></ul><ul><ul><li>Decouples transport from services and applications . </li></ul></ul><ul><ul><li>Application gateways provide third-party applications access to exposed NGN capabilities through the ANI . </li></ul></ul><ul><ul><li>Uses IP as the main transport protocol (everything over IP). </li></ul></ul><ul><ul><li>Provides support to a diversity of access and core technologies (IP over everything). </li></ul></ul><ul><ul><li>Media transference as well as control and management information are controlled directly by the “ Transport Control Functions ” based on information from the “Transport User Profiles.” </li></ul></ul>A First Glance Comparison of NxGN & NwGN
  8. 8. Next Generation Networks <ul><li>Main features of NGN-GSI (2/3): </li></ul><ul><ul><li>Provides integrated QoS control , traffic and security management . </li></ul></ul><ul><ul><li>Admission control involves verifying authorization based on use profiles, SLA (Service Level Agreement) , operator rules, service priority and resource availability in core and access segments. </li></ul></ul><ul><ul><li>The “ Service Control Functions ” are componentized, i.e., new service control components can be implemented in future releases and deployed to provide new functionality. </li></ul></ul><ul><ul><li>“ Service Control Functions ” include gateway controllers and SIP proxies (very similar to IMS). </li></ul></ul>A First Glance Comparison of NxGN & NwGN
  9. 9. Next Generation Networks <ul><li>Main features of NGN-GSI (3/3): </li></ul><ul><ul><li>SIP message routing creates an overlay over IP routing. </li></ul></ul><ul><ul><li>Virtually every service depends on SIP proxies and session establishment. </li></ul></ul>A First Glance Comparison of NxGN & NwGN
  10. 10. New Generation Networks A First Glance Comparison of NxGN & NwGN What about the main features that are common in Future Internet Design approaches?
  11. 11. New Generation Networks <ul><li>Main features of NwGN (1/4): </li></ul><ul><ul><li>Mobility and Ubiquity </li></ul></ul><ul><ul><ul><li>Refer to anywhere/anytime communications wherever/whenever a person (or an object) is. </li></ul></ul></ul><ul><ul><li>Capacity, reliability and availability </li></ul></ul><ul><ul><ul><li>Refer to network features to provide the services required by the users and, security and privacy refer to safety in using the network. </li></ul></ul></ul><ul><ul><li>Real-virtual world integration </li></ul></ul><ul><ul><ul><li>Aims at contextualizing real world information to enhance virtual world services and applications. </li></ul></ul></ul><ul><ul><ul><li>Network Enabled Devices with Internet access form what is being called Internet of Things . </li></ul></ul></ul>A First Glance Comparison of NxGN & NwGN
  12. 12. New Generation Networks <ul><li>Main features of NwGN (2/4): </li></ul><ul><ul><li>Generality </li></ul></ul><ul><ul><ul><li>It is to provide means to use generically network substrate (hardware) resources, such as transport, storage and processing capabilities. </li></ul></ul></ul><ul><ul><ul><li>This can be implemented by means of virtualization techniques. </li></ul></ul></ul>A First Glance Comparison of NxGN & NwGN
  13. 13. New Generation Networks <ul><li>Main features of NwGN (3/4): </li></ul><ul><ul><li>Content/Information-centrism </li></ul></ul><ul><ul><ul><li>It means the ability to handle content/information itself as a first-class citizen in the architecture. </li></ul></ul></ul><ul><ul><li>Service-centrism </li></ul></ul><ul><ul><ul><li>Can be referred as the capability of handling services themselves as addressable entities in the architecture, pushing the principles behind Service-Oriented Architectures (SOA) to be at the core of future inter-networking. </li></ul></ul></ul>A First Glance Comparison of NxGN & NwGN
  14. 14. New Generation Networks <ul><li>Main features of NwGN (4/4): </li></ul><ul><ul><li>Autonomic networking </li></ul></ul><ul><ul><ul><li>It is the so-sought attribute that could minimize human activity in network operation. </li></ul></ul></ul><ul><ul><ul><li>The idea is to design networks capable to self-manage, self-control, self-optimize, self-configure, self-heal, etc., generically speaking, networks with self-* properties . </li></ul></ul></ul>A First Glance Comparison of NxGN & NwGN
  15. 15. Comparison A First Glance Comparison of NxGN & NwGN
  16. 16. Comparison A First Glance Comparison of NxGN & NwGN
  17. 17. Comparison A First Glance Comparison of NxGN & NwGN
  18. 18. Conclusion <ul><li>Both developments have different timing scopes. </li></ul><ul><li>There is a need for steering networking research agendas. </li></ul><ul><li>Migration, interoperability and co-existence need more investigation. </li></ul><ul><li>NwGN constitute a never-ending set of promissory solutions for these limitations and others, but currently lacks on integrated proposals. </li></ul><ul><li>Overarching and pragmatic research steps seem necessary to convey the requirements and incentives of the multiple parties. </li></ul>A First Glance Comparison of NxGN & NwGN
