• 客户现网分为10个区域HUB，22个cluster，国际IGW只有一个节点，在BKK；所有业务需要先从就近的Cluster汇聚到区域HUB，然后在传回BKK。原因是cluster距离BKK一般都非常远，而且客户现网因为光纤质量问题禁止使用拉曼，如果直接波长穿通的话OSNR无法满足，必须使用中继；比如下图，东北部一共两个cluster和两个HUB；从cluster到IGW的业务都要在KKN和NMA两个HUB节点终结。这种方式不但提高了建网成本，也增加了两个HUB的单点失效压力。

• Customer network is divided into 10 regional HUB,22 cluster, international IGW has only one node in BKK; all business needs from the nearest Cluster brings together the regional HUB, and then back to BKK. Because BKK cluster distance is very far, and customers network because fibre quality of prohibiting the use of Raman, OSNR if direct penetrating wavelengths are not met, you must use a relay; for example the following figure, altogether two cluster and two Northeast HUB from cluster IGW's business in KKN end and two NMA HUB node. This approach not only improves the network costs, also increased by two single points of failure pressure of the HUB.

• Customer current network is divided into 10 regions HUB, 22 Ge cluster, international IGW only one node in BKK; Cluster all businesses need to start gathering the nearest regional HUB, then returned BKK. The reason is that cluster distance BKK generally very far, and existing network customers because of quality problems prohibit the use of Raman fiber, if the direct wavelength penetrating words OSNR can not be met, you must use a relay; for example the following figure, a total of two northeastern cluster and two HUB; IGW business from cluster to be terminated in KKN and NMA two HUB nodes. In this way not only improves the cost of network construction, also increased the single point of failure pressure two HUB.

Customer network is divided into 10 regions HUB, 22 cluster, the international IGW only one node in the BKK; all the business needs to converge from the nearest Cluster to the regional HUB, and then returned in the BKK. The reason is that the cluster distance BKK are generally very far and customers network quality problems because of the fiber prohibited using Raman, if direct wavelength wear through the words of OSNR unable to meet must use relay; for example below. Northeast of a total of two cluster and two hub; from cluster to IGW business to KKN and NMA two hub nodes in the end. This method not only improves the cost, also increased the pressure of two HUB single point of failure.
