Typical REN and its Architecture 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 9/30/2016 3 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 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. 9/30/2016 4
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 9/30/2016 5

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 universities 9/30/2016 7
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. 8

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 Tvet ins, mizan, kombolcha,adama, yekatit, yirgalem 9/30/2016 21
