Draft Final Report 7.1.7 Chapter 7 Outline of Scope of Works National Gateway Overhaul (1) Current situation The national gateway in Myanmar is currently provided by equipment with a transmission capacity of 13.3Gbps located in Yangon. Two pairs of IX routers with a capacity of 10GbE have been installed in Yangon and Naypyitaw respectively by December 2013 under the Project for Urgent Improvement of Communications Networks implemented with Japanese Government grant aid. (2) Necessity (Relevance) Under this project, it is planned to install a 100Gbps router in Yangon and in Naypyitaw as a national gateway. With regard to the relevance of the plan, as shown in Table 5.2-7 in Chapter 5, the total international communication speed (design value) is 437.71Gbps. This is the value needed as the total for all transmission routes across national borders. Presuming that a gateway exchange is established in all three metro-cities, approximately 150Gbps will be required as the processing capacity required for each gateway exchange. Therefore, the 100Gbps capacity of the routers to be installed in this plan is not excessive. (3) Scope of upgrade The network configuration is described in Figure 7.1-15 Outline of International Gateway Exchange. It will be installed in the Hantharwaddy Exchange in Yangon and the new Dakekina Exchange in Naypyitaw. (4) Equipment to be introduced Routers capable of meeting 100GbE standards (IEEE 802.3ba) will be installed. In addition, considering the importance of the international gateway exchange, one spare router will be added in an effort to enhance reliability by a duplex configuration. An outline is given below. ・ Yangon: Two IX Routers (100Gbps), one will be for backup ・ Naypyitaw: Two IX Routers (100Gbps), one will be for backup 7-27
