2. RNP Introduction – The Brazilian NREN
Ipê Network
RNP National backbone
Network connections
Situation on August 2016
Composed by 27 PoPs
(Points of Presence)
Aggregated capacity 325 Gbps
International capacity 116 Gbps

3. RNP Introduction – Network extension
Total size : 8,516,000 km2 Europe excluding Russia = 6,900,000 km2
Australia
Europe
USA

4. RNP Introduction – NOC Team
Network Operation Center – 24x7 monitoring service NOC team alert technical teams contacting each 10 minutes

5. Motivation Some difficulties
Reactive action in some failure situations
Lack of visibility in identifying affected services
No statistics of services availability
Dependence of PoP team’s reporting to follow connectivity health
Lack of monitoring information during connection failure events
Action plan
“Promote the evolution of monitoring to improve the quality of management, inserting new tools and expanding the scope”

6. Proposal Strategy of evolution
To implement a set of projects in order to improve the monitoring :
Project 1 : Monitoring tools evolution (2015 – concluded)
Project 2 : Monitoring scope evolution (2015 – in progress)
Project 3 : Monitoring scope expansion (2016 – in progress)

7. Project 1 : Monitoring solution – Initially
Centralized architecture
Single point of failure
Ipê
Network

8. Project 1 : Monitoring solution – Model
Distributed architecture
No single point of failure
Better reliability
Open source software
Based on Nagios code
Load distribution
Ipê
Network

9. Project 1 : Monitoring solution – Nowadays
RNP implementation
27 poller – remote monitoring agents (one in each PoP)
Monitoring 1,037 hosts with 3,012 elements until the moment
High resilience in case of failure
Ipê
Network

10. Project 2 : Monitoring scope evolution
Roadmap
Availability monitoring
Conectivity monitoring (already done)
IT infrastructure monitoring (2015)
Corporate services monitoring (2016)
Advanced services monitoring (2017)
Performance monitoring (2018)
Quality monitoring (2019)

11. Project 2 : Monitoring scope evolution
Previous scope : Network and IT Infrastructure (based on SNMP)
RNP NOC

12. Project 2 : Monitoring scope evolution
New scope : Add customer connectivity and RNP services (functional tests)

13. Project 2 : Monitoring scope evolution
Inclusion of 16 Advanced Services
CAFe (federation)
Web Conference
eduroam
FIX
(VoIP)
ICPEdu (CA)
IDC (colocation)
Telepresence system
TV Signal Transmission
Live Video Transmission
Videoconference
Video on Demand
Edudrive (cloud storage)
Compute (IaaS)

14. Network layers monitoring history
Project 3 : Monitoring scope expansion
Inclusion of customers Connectivity
Network layers monitoring history
CORE Layer:
Ipê Network backbone
monitored since 2007
DISTRIBUTION Layer:
27 Points of Presence
10 PoPs monitored since 2016
ACCESS Layer:
1,237 customers with
3.5 million users
497 customers monitored
since 2016

15. Benefits and conclusion
Results already perceived due efforts done during last 2 years :
Adoption of a new monitoring tool
Better availability of monitoring service
Load distribution through remote monitoring agents (pollers)
Monitoring resilience in case of connection failure
Possibility of services monitoring through functional tests
Construction of a services monitoring view
Quicker failure identification
NOC operators contact appropriate technical teams
Smaller resolution time
Better service management and support
Inclusion of monitoring customers connectivity
Proactive action on customers’ connectivity failure
Better customer satisfaction
Better network management and planning
