RINA aims to provide advantages over the current Internet by optimizing all phases of communication. The study evaluates RINA's performance compared to TCP in a one-ISP scenario. It finds that RINA reduces preparation time compared to DHCP and DNS in the Internet, and improves efficiency for subsequent connections by reusing existing flows. RINA shows potential to combine benefits of TCP extensions like Fast Open. Future work includes optimizing RINA proxies and investigating a full transition from the Internet to RINA.

RINA in a nutshell
• Networking is only IPC
• IPCP – a container that provides
many functionalities like:
- routing
- transport
- security
- management
• DIF – a single type of layer that
recursively repeats itself
• Two protocols:
- Error and Flow Control Protocol (based on Delta-t)
- Common Distributed Application Protocol
• Three types of nodes: Hosts, Interior routers, Border routers

4. 4/11
Motivation
• Advancing the RINA deployment
• Proving that RINA can show great performance
• Investigating the possibility of directly switching from the Internet to RINA

5. 5/11
One-ISP scenario
• First contact: The very beginning, when no preparations were made by the end
hosts to enable communication (except the DNS Server)
• Second contact: A host has already found the peer and managed to talk to it,
and local host caches were filled with information.

6. 6/11
Internet vs. RINA
• Preparation: In the Internet, it includes the DHCP and DNS procedures.
In RINA, this phase is composed of the Enrollment and App. discovery.
• Establishment: 3-way handshake in the Internet – End-to-end flow allocation in RINA.
• Data Transfer: The time between the first GET and the response from the server.

7. 7/11
Evaluation
• The Preparation phase takes longer than the other two phases.
• DHCP + DNS procedures take more time than the RINA Enrollment and App. Discovery.
• Optimizing the RINA prototype will reduce the timing overhead in the communication phases.

Evaluation (2)
• RINA and TFO do not need an extra round-trip in the second contact.
• The end hosts will use the same flow (as long as it is not deallocated) with a new
connection state.
• RINA ‘’always’’ works.

Conclusions
• RINA is designed to provide several advantages over the
current Internet.
• It shows to be efficient during all phases of the
communication and specially in the ‘’second contact’’.
• Has all the potential to combine the benefits of several TCP
extenstions.

10. 10/11
Future Works
• investigating the use and optimization of RINA_Proxy
• how to perform a full “switch-over” to RINA (Happy Eyeballs)
