REN- Research and education
networking is the provision of
computer networks for
interconnecting research and
educational institutes in order to
facilitate exchange of information for
research and teaching purposes.
A layered model
Global Connectivity, Regional
RENs
NRENs
All users are connected at the
campus network level (No scientist
is connected directly to a National
Network. They are all connected to
campus or enterprise networks)
National Research and Education Networks (NRENs) NERN is a network for a closed user group which has advanced connectivity requirements to
support research and education needs. It provide the infrastructure for data communicationand data services for the group. Commonly NEREN rent telecommunication lines fromCommercial providers, while owning the equipment required to route traffic through them
NEREN is essential for participation in data-intensive, collaborative research. The enormousvolume of data that is transmitted over the network, and the need to connect withinternational peers and resources available only through global NREN partners.
NREN partners provide the ultra-high-speed connections directly to institutions within theirprovince or territory.
They are not-for-profit organizations providing advanced services to a well boundedcommunity.
CLOSED USER GROUP, Not in the business of providing public access, NOT A PUBLICNETWORK
Running an NREN is much more than providing connectivity.
About one hundred countries in the world have adopted NRENs as the centerpiece oftheir information and communication technology (ICT) plan for tertiary educationinstitutions, connecting research institutes, and other institutions, such as schools andhospitals.
Once should have a NRENs it is easy to be part of the Global Network for OpenEducation , africa Grid ,etc.

NRENs in the World
NRENs have been in existence in Africa since 14 years ago
The first NREN to be established & operationalised was KENET in
1999 And the second NREN was TENET in 2001

What is EthERNet?
The Ethiopian Education and Research
Network (EthERNet) was initiated in 2001
as part of a national capacity building
program along with SchoolNet and
WoredaNet
Project’s aim was to build capacity of public
universities to share educational resources
and research among member institutions
locally and globally, in a phased approach
First Phase – Implementation of
LAN/WAN for six relatively old public
universities
Second Phase -Tele-Education and Tele-
Medicine (MPLS/VPN) for Tele- Education
purposes
Third Phase - E-Library System, for all
public Universities, which include computer
labs for 13 2nd generation universities9/30/20167

Ethiopian Education and Research Network (EthERNet) is the Ethiopian National Researchand Education Network (NREN) had spent more than 1.2 billion ETB to do itsinfrastructure project.
EthERNet 40G backbone with 10G access to 36 public Universities and Institute ofTechnologies having its own state of the art Data Center and Network Operation Center iscommissioned .
The optical (fiber) backbone is built on highly reliable OPGW and ADSS on EEU highvoltage lines
4841 Km of fibers are used
Exchange Point/Internet Gateway is at EthERNet Data Center in Addis Ababa to peer withneighboring NRENs (SudREN, KENET, SolmaliREN) and ultimately will connect toUbuntuNet, GiANT, Internet2 and all other global research and education networks.

Contribute to inter-institutional collaboration, research and human networking.
Promote joint institutional content development, access to large databases and sharing of
research results
Some of the applications that can be hosted at EthERNet Data Center
DNS – edu.et ,Email,E-library,Video Conferencing System, LMS, EduRoam
Research Collaboration Platforms
Students and staff developed social networking and other useful applications
SaaS – Software as a Service, STaaS – Storage as a Service, BaaS – Backup as a Service, TEaaS – Test
Environment as a Service
Use ICT technologies to make widely accessible teaching materials and tools such as multi-
media based training …
Helps solve the serious lack of ICT manpower on the part of new Universities
Sharing expensive equipment like mainframe, supercomputer, electron microscope,
telescope
There is already massive pool of valuable world class resources available freely to the non-
profit world of REN

Phase II
1. 19 or more higher education to be connected to the EthERNet network.
2. Meshed transmission
The transmission network will be meshed topology, and the ring topology
shall increase from 2 to 5 Rings.
This will enhance the network security, strengthen service availability.
3. Full OPGW migration
Most of the fiber route uses the exsiting OPGW cable, but needs to migrate
the rest that uses the exsiting ET’s optical fiber cable. Meanwhile, it needs
to push EEU to prioritize the OPGW construction in favor of the cities
which accommodate universities.
4. Redundancy at the aggregation layer
For the aggregation layer, one more AG router should be for each
aggregation site
