Is Internet getting old !!

  1. 1. Is Internet getting old !! ❏ What (computer) network architecture is ❏ What is the current one ❏ What are its main flaws ❏ How to construct a better architecture
  2. 2. ❏ 1972: Multihoming not supported by the ARPANET Computer networking is Inter Process Communication (IPC) – Robert Metcalfe, inventor of Ethernet, 1972
  3. 3. ❏ 1978 TCP split from IP ★ The ARPANET switched to TCP/IP in 1983. ★ TCP/IP was developed in the 1970s and adopted as the protocol standard for ARPANET (the predecessor to the Internet) in 1983.
  4. 4. ❏ what are the “endpoints” of communication” today ?? ★ Application ★ Network are just large data copying machines
  5. 5. ❏ Overview of TCP/IP
  6. 6. ➔ Complexity makes all other network problems worst (security, management, etc), makes networks hard (and expensive!) to manage and less reliable.
  7. 7. ❏ Current network architecture has a flawed ...
  8. 8. ❏ Fixed number of layers , sometimes more needed between transport and application - Need concepts like “Overlay”, “VPN”, “Virtual Networks”, .. ❏ Each layer providing a different function to each others . ❏ Internet architecture does not have root for different network protocols ( There is a common internet layer directly over data link layers ) ❏ Multiple protocol within the same layer ❏ Layers & problems !!
  9. 9. ❏ Issues: mobility (II)
  10. 10. ❏ HOW TO CONSTRUCT A BETTER NETWORK ARCHITECTURE
  11. 11. ❏ Let’s go to fixed ( what is new ?? ) ❖ Meet RINA ! ● The principles behind RINA were first presented by John Day in his 2008 book Patterns in Network Architecture
  12. 12. RINA is a new network architecture that is based on the fundamental principle that networking is inter-process communication (IPC). It recurses the IPC service over different scopes.
  13. 13. ❏ Basic concept of RINA
  14. 14. ❏ Overview Recursive Internet Architecture (RINA): RINA is a new network architecture that is based on the fundamental principle that networking is inter-process communication (IPC). It recurses the IPC service over different scopes. From the publishing of the PNA book in 2008 to 2014, a lot of RINA research and development work has been done.
  15. 15. Summing up.. RINA is not a protocol!
  16. 16. ❏ One isp scenarios
  17. 17. ❏ Let’s go to our to-do list
  18. 18. ★ As a consequence of its structure, many capabilities supported by RINA are accommodated without specific mechanisms. As one would expect in a complete architecture, so-called middleboxes are unnecessary, and so-called ``layer violations" do not exist. ★ Network Structure Enhancements ★ Economic Efficiency ❏ Benefits of RINA ??
