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????

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.
