[NANOG] NREN Network Design
I'm try to redesign the Sudanese NREN (National Research & Education Network). we provide end to end service,to our customers. Our network is build over local ISPs. But the problem of the current design that each time we need to go back to the ISP to change our Infrastructure IP addresses, when the situation need this.How can solve this? I heard about something called Virtual Network Environment which give us the full control of ISP routers, is it the best solution? What about others NRENs.Thanks Normal0falsefalsefalseEN-USX-NONEAR-SAMicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} --------------------------------- Eng.

Tarig, I am not quite sure what you mean, but it sounds like you're suggesting that different pieces of your network are fragmented across different connections to different ISPs. Depending on what exactly the problem is, the solution would be either (a) to get a provider-independent IP block from your RIR and route-peer with each of these ISPs in order to announce independent address space that travels with you wherever you buy connectivity, and/or (b) some sort of Layer 2 or 3 tunneling like VPN or MPLS, if I'm not understanding the problem correctly. -- Alex -- Alex Balashov - Principal Evariste Systems LLC Tel : +1 678-954-0670 Direct : +1 678-954-0671 Web : http://www.evaristesys.com/
Tariq It's really nice to hear from Sudan in NANOG :) , the problem as Alex state it's not clear at all a PI address / BGP peering could be a solutions for it , VNE (Virtual Network Environment) it's to isolate the applications located in one machine in virtual networks like ( VMware ) using it , so can you please give us more details about the problem Thanks a lot Rashed Alwarrag Applied Technologies NOC Manager -----Original Message----- From: Tarig Yassin Adam [mailto:tarig@suin.edu.sd] Sent: Tuesday, February 02, 2010 5:26 AM To: nanog@nanog.org Subject: [NANOG] NREN Network Design I'm try to redesign the Sudanese NREN (National Research & Education Network). we provide end to end service,to our customers.

Hi Rashed This my first time to hear about app-tec company. I'm very happy to see this in Sudan. In fact We applied for PI address form AfriNIC and our request is approved. But the current design depends on our ISP (SUDATEL) and we using their routers. we have a router (One point to access our NREN) in every University, and two NOCs in our TOP Universities (Sudan, and Khartoum), for connecting them our ISP interconnect them with MPLS VPN layer3 at Provider Edge. So our traffic is routed via through their ISP. I think this is the problem. but how we can solve it????
