through layers
• Layers (DIFs) are distributed applications that provide IPC services to higher layers (which
may be DIFs or other forms of distributed applications)
• Layers are resource allocators: they manage the layer resources (memory in buffers,
scheduling capacity, bandwidth) and provide them to competing flows.

• RINA recursive layering structure cleans up and generalizes the current
protocol stack.
• Example 1: PBB-VPLS (Virtual Private LAN Service)
– Uses MAC-in-MAC encapsulation to isolate provider’s core from customers addresses and VLANs

Namespace Management Security Management
• All layers have the same mechanisms and 2 protocols (EFCP for data transfer, CDAP for layer
management), programmable via policies.
– All data transfer and layer management functions are programmable!
• Don’t specify/implement protocols, only policies
– Re-use common layer structure, re-use policies across layers
• This approach greatly simplifies the network structure, minimizing the management overhead and
the cost of supporting new requirements, new physical media or new applications
EFCP

Error and Flow Control Protocol (EFCP)
• One of the main results discussed in Patterns in Network Architecture
(PNA), later formalised in RINA.
– PNA/RINA only proof this is possible and show a way of arriving to the result. If others
propose simpler frameworks with the same capabilities we should definitely go for them.
• By separating data transfer protocol elements between mechanism (invariant)
and policy (variant), it is possible to specify a data transfer protocol framework
from which multiple data transfer protocols can be generated by
– Choosing a concrete syntax (length of PCI fields)
– Plugging in the right policies
• See EFCP specification for an example of such protocol framework
22

EFCP (II)
• 1 common data transfer PDU
– Abstract syntax: (presence/absence and length of fields varies
– E.g.: point to point links -> no need for addresses
– 1 application only per IPCP -> no need for cep-ids (e.g. some IoT protocols)
• A few control PDUs (Ack, ack & flow ctrl, etc.)
• Policy plug-in points to customize for different environments and application requirements
– Flow control (window/rate-based), retransmission control, congestion control
23

E.g. Results on congestion control (I)
• “Congestion control in the Recursive Internetwork Architecture”
– P. Teymoori, M. Welzl, S. Gjessing, E. Grasa, R. Riggio, K. Rausch, D. Siracussa
– IEEE ICC 2016
– https://www.researchgate.net/publication/301657524_Congestion_Control_in_the_Recursive
_InterNetworking_Architecture_RINA
– “… we have shown that congestion control in RINA “naturally” exhibits properties of various
improvements that have been made to (or at least proposed for) the Internet, without
inheriting the problems that come from imposing these mechanisms on an architecture
that was not made for them … ”
24

Results on congestion control (II)
• RINA can solve the Internet c. c. problems by:
– Breaking up the control loop in shorter ones
– Controlling flow aggregates inside the network and
– Enabling the deployment of arbitrary controllers per DIF
• Follow up: OCARINA project (lead by U of Oslo)
25

DIF API
• register / unregister (app name)
– Associate applications to DIFs
• allocate_flow(dest_app_name, QoS attributes)
– Allocate a flow to a destination app name (may name a group of apps), with a certain QoS
(reliable delivery, in order delivery, bounds on delay/jitter, minimum capacity, etc.)
• read/write (port_id)
• deallocate_flow(port_id)
– Free up resources associated to the flow
26

Dynamic negotiation of cep-ids and policies
per flow
• Application calls “allocate”
– Provides dest. app name and flow requirements
• IPCP(source) selects EFCP policies and computes source cep-id, sends message to IPCP (dest)
• IPCP (dest) does access control check, selects EFCP policies and computes dest cep-id
• Today
– applications have to select the protocol explicitly
– static (well-known) ports as cep-ids
– No app names, addresses exposed to apps
27

NAMING, ADDRESSING, MOBILITY
28

Naming & addressing
Application names: Assigned to applications. Location independent. Uniquely identify application within an application
namespace. In general name a set (can have a single member).
Addresses: Location-dependent synonym of an App name. Facilitates locating the app within a certain context (e.g. IPCPs in
a DIF). Its scope is restricted to the DIF.
Port-ids: Identifies one end of a flow within a system (local identifier), only id shared with user.**
Connection endpoint ids (cep-ids): Identify the EFCP instances that are the endpoints of a connection.
QoS-id: Identifies the QoS cube to which the EFCP PDUs belong (PDUs belonging to the same QoS-id receive receive a
consistent treatment through the DIF).

Implications
• With a proper naming and addressing structure in place, life network
renumbering can be done
– without impacting existing flows
– without the need of extra protocols or mechanisms
– in a fully automated way (minimize opex and network downtime)
• Use cases
– Network consolidation (e.g. acquisition of other networks)
– Update network addressing scheme to optimize routing (e.g. due to changes in network
topology)
– Better support for mobility (change address of moving nodes if they attach to different
subnets)

different parts of the mobile network
• Each application can use the DIF that provides enough scope and QoS for its communication
needs -> not restricted to the “top ones”
• All layers have the same structure and protocols, implementations can be highly optimized;

Some results on Mobility Management
• “Mobility Management in RINA networks: experimental validation of architectural
policies”
– E. Grasa, L. Bergesio, M. Tarzan, D. Lopez, S. van der Meer, J. Day, L. Chitkushev
– IEEE WCNC 2018, Barcelona
– Paper not online yet
– “This paper analyses what properties such schema needs to have, and discusses how Internet
mobility solutions are missing parts of it. Then it looks at RINA, a network architecture with a
complete naming scheme. Theoretical analysis backed up by experimental validation of the main
properties for mobility support shows that managing mobility in RINA networks not only is simpler
and easier to scale compared to the Internet situation, but also that no special protocols or
mechanisms need to be added to RINA in order to support mobility.”
43

Some results on cost of mobility
• “On supporting mobility and multi-homing in Recursive Internet
Architectures”
– V. Ishakian, J. Akinwuni, F. Esposito, I. Matta
– Computer Communications, 2012, Vol. 35, Issue 13
– http://www.cs.bu.edu/fac/matta/Papers/RINA-ComCom2012.pdf
– “In this paper, we present a specification of the process of ROuting in Recursive
Architectures (RORA). We also perform an average-case cost analysis to compare the
multihoming / mobility support of RINA, against that of other approaches such as LISP and
Mobile-IP. Extensive experimental results confirm the premise that the RINA architecture and
its RORA routing approach are inherently better suited for supporting mobility and
multihoming.”

– https://www.researchgate.net/publication/309782103_Benefits_of_Programmable_Topological_R
outing_Policies_in_RINA-Enabled_Large-Scale_Datacenters
– “… we propose rule-based topological routing and forwarding policies tailored to the
characteristics of publicly available Google’s and Facebook’s DCNs… Numerical results show
that the scalability of our proposal depends on the number of concurrent failures in the DCN
rather than its size (e.g., number of nodes/links), dramatically reducing the total amount of routing
and forwarding information to be stored at nodes. “

Network management
Commonality is the key to effective network management
From managing a set of layers, each with its own protocols,
concepts and definitions …
… to managing a common, repeating structure of two protocols
and different policies
• Commonality and consistency in RINA greatly simplifies management models, opening the door
to increased automation in multi-layer networks
– Reduce opex, network downtime, speed-up network service delivery, reduce components that need to be
standardised

– TEERNA Networking Conference
– https://tnc16.geant.org/core/presentation/667
– “This paper performs a comparative analysis in the complexity of managing an IP-based and
a RINA-based large-scale multi-tenant data centre networks. Configuration management is
the main target of the analysis although some hints on performance and security
management are also provided. The analysis shows that the commonality built into the RINA
architecture and the single type of recursive layer with a uniform API greatly reduces the
complexity of the models the Network Management System (NMS) uses to understand the
state of the managed network.”

Some results on network management
• “Taming policy complexity: Model to Execution”
– S. van der Meer, J. Keeney, L. Fallon
– IEEE NOMS 2018
– Paper not online yet
– “However, policy-based management as a standalone domain has never been evaluated in
terms of which parts are variant / invariant, i.e. which parts of policy-based management can
be domain-, model-, language-, use case-independent. In this paper, we introduce and
define a formal universal policy model that does exactly that. The result is a model that can
be used to design, implement, and deploy immutable policy infrastructure (engine and
executor) being able to execute (virtually) any policy model.”

Deployment
New technology but incremental deployment
• RINA can be deployed incrementally where it has the right incentives, and
interoperate with current technologies (IP, Ethernet, MPLS, etc.)
– Over IP (just like any overlay such as VXLAN, NVGRE, GTP-U, etc.)
– Below IP (just like any underlay such as MPLS or MAC-in-MAC)
– Next to IP (gateways/protocol translation such as IPv6)
