With the rapid development of the Internet and cloud services, the service bearer network is also deployed through cloud technology, DWDM/OTN solution reduces network construction costs and improves bearer efficiency.
The cloudized network resource pool is based on the centralized deployment of DCs, the traffic between DCs has explosive growth every year. According to related reports, the number of data centers (DC) will increase by 4 times by 2025, and the data center (DCI) traffic will compound annually. The growth rate reached 50%.
The growth of traffic between data centers has doubled the lease cost of leased lines. The traffic between DCs has gradually become the main traffic of the transmission backbone network. The traditional business network construction model based on administrative districts will inevitably shift to a DC-centric network construction model.
DWDM/OTN solution realizes the Mesh interconnection between most network nodes, and the business adopts a one-hop direct approach to minimize the delay through the network nodes to ensure the real-time exchange of data between DCs and meet the high real-time cloud services in the future Sexual requirements.
The traditional DCI data center interconnection uses bare optical fiber direct-drive interconnection. In this way, a single optical fiber can only run a single service, which is far from meeting the needs of large data, large bandwidth, and large traffic expansion between DCs. HTF launched Miniaturized and highly integrated DWDM/OTN solution.
