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
