Each DC and branches of CBM and FIs are connected through the WAN network provided by a local network carrier, Myanmar Post and Telecommunications (hereinafter MPT). Source: Preparatory Survey Team Figure 3-32 Physical network diagram for CBM-NET Phase 2 In each location of DC and CBM branches, devices and cables will be redundant to minimize downtime in case of a hardware failure. Some multiple devices are virtually integrated as a single device to enhance the level of redundancy and reduce the management workload. On the other hand, some devices are virtually divided to function as multiple devices to utilize the resources efficiently and reduce the number of physical hardware devices. For example, a firewall, load balancer, and core L3SW are shown as single pairs at each DC site in the diagram above. However, in the logical view as follows, they appear multiple times as multiple devices with different roles. 76
