The document discusses RINA (Recursive InterNetwork Architecture), a new internetwork architecture proposed as an alternative to TCP/IP. RINA recognizes that all networking involves interprocess communication (IPC) between application processes. It models networking as a series of distributed IPC layers, with each layer providing IPC over a certain scope. Communication between processes goes through three phases - enrollment, flow allocation, and data transfer. The PRISTINE project is researching topics around implementing RINA such as naming, routing, security, and evaluating its performance for application scenarios like distributed cloud computing.

- 1. Future Network architecture RINA: Recursive InterNet Architecture FP7 EU Project (2014-2017): PRISTINE Anis Laouiti, Hakima Chaouchi Anis.laouiti@telecom-sudparis.Eu hakima.chaouchi@telecom-sudparis.Eu Presented at UCOOL STIC AMSUD Project Workshop: 6-7 Oct 2014, Paris
- 2. Future Network approach that started in Boston University by John Day and supported by Louis Pouzin Society!!
- 3. Recursive InterNet Architecture (RINA) • New internetwork architecture • Unified theory of networking • A layer = a distributed application that provides IPC (Interprocess Communication) over a certain scope, called a Distributed IPC Facility (DIF) • Recurse as much as needed • Can be configured to a certain policy 23/10/2014 3
- 4. Communication between application processes Not to be confused with communication between interfaces TCP/IP !!! Basic premise: All networking is inter process communication and IPC only All communication goes through three phases: Enrollment Flow allocation Data transfer 23/10/2014 4

- 6. Recursive InterNet Architecture • Recognizes the three phases all communication goes through! All communication goes through three phases: Enrollment Flow allocation Data transfer • Other advantages of RINA: – Inherent support for QoS – Multihoming and mobility – More secure 23/10/2014 6
- 7. Flow allocation in RINA • Application A performs a flow allocation request • Application B responds to this request – Accept – Deny • If positive reply, a flow is created: – Port-id is assigned for further reference – Connection (with CEP-id) is maintained in lower layer while there is active data transfer 23/10/2014 7
- 8. After flow allocation 23/10/2014 8
- 9. Different research topics PRISTINE Project: FP7 EU Project • Naming and Adressing • Topological Routing • Access Control and security • Application scenarios: Distributed Cloud, others. • Traffic modeling • Performance analysis • …etc
Editor's Notes
- #6: Remember, this is the architecture! DAF Support Tasks: The IPC Management (and other management: memory, storage, CPU) tasks are usually implemented as OS functionality. IPC Resource Management: Creation/Deletion of IPC processes Multiplexing (Usually inverse multiplexing, an application flow into multiple DIF flows, for example: 1 for video, 1 for audio, 1 for text, …) SDU Protection (CRCs, encryption, TTL, …) IDD (Inter DIF Directory, find out in what DIF the destination application process is executing)
