REN-
Research and education networking is the provision
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
campus or enterprise networks)
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 communication and data services for the group. Commonly NEREN rent telecommunication lines from Commercial providers, while owning the equipment required to route traffic through them
NEREN is essential for participation in data-intensive, collaborative research. The enormous
volume of data that is transmitted over the network, and the need to connect with international peers and resources available only through global NREN partners.
NREN partners provide the ultra-high-speed connections directly to institutions within their
province or territory.
They are not-for-profit organizations providing advanced services to a well bounded
community.
CLOSED USER GROUP
, Not in the business of providing public access, NOT A PUBLIC NETWORK
Running an NREN is much more than providing connectivity.
About one hundred countries in the world have adopted NRENs as the centerpiece of
their information and communication technology (ICT) plan for tertiary education institutions, connecting research institutes, and other institutions, such as schools and hospitals.
Once should have a NRENs it is easy to be part of the Global Network for Open
Education , africa Grid ,etc.

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

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
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 universities

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

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.
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.
