RINA & QTA‐Mux
• Clean‐slate network architecture for the Future Internet, based on a
single type of layer called DIF (i.e., Distributed IPC Facility)
• Multiple DIF instances are always stacked one on top of another, each
one providing Inter‐Process Communication (IPC) services to the DIFs or
applications above
• DIFs implement the same two protocols,
customizable via programmable policies
• The QTA‐Mux policy is the responsible for
the RINA QoS support
• However, its performance has been only
evaluated on single isolated DIF scenarios

Objectives of this work
1. To define QTA‐Mux deployment scenarios and QoS Cubes to be
enforced in a large‐scale Metro‐Regional RINA network scenario with
multiple DIFs stacked one on top of another
2. To emulate a realistic large‐scale RINA network scenario by injecting
synthetic traffic flows reproducing heterogeneous applications
3. To evaluate the RINA QoS support by measuring the QoS metrics
perceived by such injected synthetic traffic flows end‐to‐end
4. To perform a real HD video (1080p) streaming demo to better show
the RINA QoS support under high congestion

Experiment description (1/3)
• To conduct the experimentation activities, a 37‐Node Metro‐Regional RINA
network has been setup in the Virtual Wall experimentation facility:
37 Physical machines requested, where a
Linux (Ubuntu 14.04) image with the IRATI
RINA Stack has been installed
‐ 9 Interior Routers (IRs)
‐ 8 Provider Edge (PE) routers
‐ 15 Home Routers (HRs)
‐ 1 Data Center Border Router (BR)
‐ 1 Video Server (S1)
‐ 3 Video Client (C) nodes

Experiment description (3/3)
• Two different QTA‐Mux deployment scenarios have been evaluated:
 At both SPN and MR DIFs
 Only at the SPN DIF
• Offered QoS Cubes at SPN and MR DIFs (when QTA‐Mux configured) and
synthetic traffic flow characteristics:

Obtained results:
QTA‐Mux at both SPN and MR DIFs
• 75 bidirectional synthetic traffic flows injected into the SPN DIF (15 of
each type); NIC capacities between IRs limited to reproduce 80% and 90%
offered load scenarios
• Adequate QoS differentiation, even under high congestion:
100% in
< 5ms
Perceived QoS metrics (90% load)
100% in
< 1000ms

9. J. Perelló, A. López, D. Careglio, “Experimenting with Real Application‐specific QoS Guarantees in a Large‐scale RINA Demonstrator” 9
Obtained results:
QTA‐Mux at the SPN DIF Only
• 75 bidirectional synthetic traffic flows injected into the SPN DIF (15 of
each type); NIC capacities between IRs limited to reproduce 80% and 90%
offered load scenarios
• QoS differentiation lost at the MR DIF (default FIFO scheduling):
All CDFs overlap
=> identical packet
treatment
Perceived QoS metrics (90% load)

HD video streaming demo (1/2)
• QTA‐Mux configured at both SPN and MR DIFs
• 75 bidirectional synthetic traffic flows injected into the SPN DIF; NIC
capacities between IRs limited to reproduce 80% and 90% load scenarios
• HD video streaming sessions (1080p video file) started from the video
server to the 3 client nodes over the HD Video Streaming Application DIF

HD video streaming demo (2/2)
• Different experiments conducted, assigning the HD video streaming flows
either the Gold or BE QoS Cube:
Perceived QoE (80% load) from 1 (worst) to 5 (best)
Perceived QoE (90% load) from 1 (worst) to 5 (best)

Conclusions
• A 37‐Node metro‐regional RINA network has been successfully emulated in
the Virtual Wall experimentation facility
• With an appropriate QTA‐Mux configuration, RINA can deliver effective QoS
support to heterogeneous applications
• Further corroborated by performing a HD video streaming demo over RINA,
experiencing perfect QoE in almost all cases when assigning to HD video
streaming flows the Gold QoS Cube
