According to Huawei, the DCI reconstruction is inevitable in the cloud era. In the traditional Internet era, services were implemented through search engines and browsing. In this Internet Plus era, users require connection to the nearest cloud data centres, causing network architecture to gradually flatten out. This leads to emergence of the DC-centric network. IDC predicts that 80 percent of enterprises services will exist on cloud computing platforms in the next two to three years. This will bring new challenges to network bandwidth latency service provisioning and on demand adjustment.
Because data traffic is increasing, and the network architecture is being reconstructed, many ISP enterprises experience the following challenges during DCI bearer network construction:
- Bandwidth challenge: To satisfy current and future requirements of rapidly developing services, DCI pipes must be made large enough to accommodate such services. However, optical fiber resources are limited, so ISP enterprises must make full use of the current optical fibers to provide large bandwidth.
- Environment challenge: Carriers' devices are not adapted to DC equipment room environments due to differences in cabinet dimensions, air intake manners, heat dissipation manners, and power supplies, resulting in high TCO.
- O&M challenge: Most ISP enterprises do not possess the capabilities for maintaining optical transport networks. This means DCI device maintenance must be simple, and devices must provide open interfaces to facilitate easy integration into the existing network system.
Huawei's OptiCloud Data Center Interconnect (DCI) platform and Huawei OSN902 enable a new cloud and network services ecosystem
Huawei's launch of its OptiCloud Data Center Interconnect (DCI) platform at the inaugural "Southern Pacific ISP Summit 2016" is a disruptive product. It is a simple, flexible and open architecture that connects cloud networks across standard interfaces such as NFC, SDN and OXC, accelerating digital transformation of verticals and creating business value for internet service providers. Similarly, Huawei OSN902 eliminates interconnection challenges with its large capacity, ability to adapt to installation conditions in data center equipment rooms, and its open management mode allows for optimal user experience on DCI bearer networks.
"Currently, Internet service providers are shifting from providing basic network and web services to providing public cloud, private cloud, and enterprise cloud services," explained Alex Duan, General Manager, WDM Domains, Transmission Network Product Line, Huawei. "The cloud era requires massive interconnection bandwidth and network architecture transformation. On traditional networks, most traffic is north and south traffic. However, in current cloud/DC-centered networks, traffic moving in an east-west manner sharply increases. Inter-DC synchronization, service disaster recovery, and pipe interconnection are required to improve DC usage, making the use of DCI the fastest growing WDM application."
DCI Solution's Value for ISP Customers
According to Duan, the Huawei DCI solution creates value for ISP customers in the following ways:
- Ultra-large bandwidth: Huawei OSN902 supports the beyond 100G optical transmission technology. It provides a capacity of more than 20T using one pair of optical fibers, and supports a flexible grid at the optical layer for continuous expansion. The feature also minimizes bandwidth resource use, helping customers reduce investment.
- Adaption to various DC installation conditions: Huawei OSN902 can be placed in 19-inch or 23-inch cabinets. It supports AC and HVDC power supplies, air inlet from front, and air outlet from rear, and its fans, power supplies, service boards, and optical modules are hot swappable. This innovative design enables it to adapt to all DC equipment room requirements from customers.
- Various open interfaces developed based on the open T-SDN software architecture: Customers can perform secondary development to integrate management of the Huawei OSN902 into DC device management systems, reducing the difficulty in routine maintenance, and ensuring the development of rapidly increasing DC services.
