OTN Application in disaster recovery deployment center
Why do we need OTN deploy in disaster recovery center?
Data is the lifeblood of the enterprise in the era of big data times . it is unintentionally approaching the edge of the crematorium If data lost, . so it needs to ensure service stability and continuity when data center processes data centrally, For example, the abnormal shutdown of the bank's trading system may cause unpredictable and significant losses. The interruption of key service will directly cause reputation loss, loss of productivity, and loss of direct income.
That's why we need deploy the backup for the disasters. In order to avoid huge losses caused by disasters in data centers, such as irresistible natural disasters such as floods, snow disasters, earthquakes, damage to computer rooms, human error or human disasters, power outages, and optical cable failures, etc.
Current request analysis
one bank is gradually expanding, with increasing of payment methods, service channels, and financial services are constantly increasing. networking expansion/upgrade is imminent. At the same time, the stability and continuous requirements of network business are becoming higher and higher. In order to avoid the construction of infrastructures such as subway repairs and building construction in the urban area ,digging etc .caused the fiber cables breaken make affect for the business , so the following requirements are required:
1. There are 20G services now, and 40G will be upgraded in the future. 20G is also required.
2. The distance of disaster recovery backup center and bank's data is 60 kilometers . It needs to meet the increasing requirements for high bandwidth, and the network can be upgraded continuously without networking shutdown in the future.
3. In order to avoid digging optical cables, banks and disaster recovery centers need back up all the time .
Case analysis
Currently, there are three transmission methods, WDM WDM, MSTP multi-service transmission platform, and optical cable direct connection.
Networking plan design
1.WDM technology can transmit 160KM without repeaters, expand the number of channels by 80 waves, and smoothly upgrade to 800G.
2.The main and backup roads each use 2 core optical fibers, which are transmitted in different optical cables. When a certain cable fails, it can be switched to another route in milliseconds, and backup can be realized.
XYT-OTN2800 multi-service optical transmission platform, including 1U / 2U / 5U / 10U chassis, can realize large-capacity transmission. Support AC 220V AV and -48V DC DC power supply, support 1 + 1 power protection.
