The document discusses the limitations of the current TCP/IP network architecture and proposes Recursive Internet Architecture (RINA) as a better alternative. RINA is based on the principle that networking is inter-process communication (IPC) that is recursed over different scopes. It was first presented in 2008 as a new architecture that supports capabilities like mobility, middleboxes, and layer violations without specific mechanisms. RINA structures the network in a way that aims to enhance its structure and economic efficiency compared to the TCP/IP model.

- 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. ❏ 1972: Multihoming not supported by the ARPANET Computer networking is Inter Process Communication (IPC) – Robert Metcalfe, inventor of Ethernet, 1972
- 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. ❏ what are the “endpoints” of communication” today ?? ★ Application ★ Network are just large data copying machines
- 5. ❏ Overview of TCP/IP
- 6. ➔ Complexity makes all other network problems worst (security, management, etc), makes networks hard (and expensive!) to manage and less reliable.
- 7. ❏ Current network architecture has a flawed ...
- 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. ❏ Issues: mobility (II)
- 11. ❏ HOW TO CONSTRUCT A BETTER NETWORK ARCHITECTURE
- 12. ❏ 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
- 13. 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.
- 14. ❏ Basic concept of RINA
- 15. ❏ 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.
- 16. Summing up.. RINA is not a protocol!
- 17. ❏ One isp scenarios
- 18. ❏ Let’s go to our to-do list
- 19. ★ 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 ??
