The financial industry backbone network is a primary backbone network that connects data centers, headquarters and branches of financial institutions. It is an important part of IT infrastructure for financial institutions. Traditional backbone network construction and O&M pay more attention to meeting business access requirements, ensuring the safe and stable backbone network operation, and focusing on how to build and monitor the network.
Under the trend of distributed data centers and cloud popularity in today's Bank4.0 era, however, the data flow model of the financial industry has undergone fundamental changes. Rapid business launch on the cloud and interconnectivity have become typical. How to meet the requirements for rapid launch of massive financial innovation business? How to satisfy different users with diversified service experiences? How to meet the requirements for flexible access by financial institutions in complex environment? The reform of basic network architecture has become the only way of digital transformation, and the backbone network, as the key infrastructure for data communications, is the top priority of network architecture reform.
At the beginning of the new-generation core backbone network plan, it is required to introduce and use new technologies, so as to meet the needs for rapid deployment of upper-layer business and intelligent traffic scheduling from the perspective of technical planning and architecture planning, and adapt to future business and technology development trends.
Requirements analysis: We analyze and evaluate customers' existing backbone architecture, traffic characteristics and customer construction requirements.
Proposal: We propose new-generation core backbone network construction solutions and intelligent backbone network O&M and service orchestration solutions.
Selection of key technologies: Evaluate the backbone network technologies currently adopted by customers, and help customers import the current mainstream technologies for backbone network based on industry trend, including Segment routing, SRv6, controller, traffic engineering and other technologies.
Migration plan: After defining solutions for new-generation core backbone network, identify risks, propose new-generation core backbone network migration plan and ensure smooth implementation of customers' business goals based on current backbone network status and customer requirements for IT construction milestones.
Change the traditional backbone network construction mode and provide integrated solutions from planning, construction, migration and intelligent O&M.
Keep close to customer and industry pain points, create new-generation core backbone network solutions tailor-made for customer needs based on the best practices in the industry and under the guidance of overall solution architecture.
Our solution inherits SDN concept and separates software from hardware. Its underlay meets basic transmission needs, overlay can be flexibly and quickly deployed for customer business.
Almost all controlled with traditional routing, and the flexibility of traffic scheduling subject to that of routing control; routing control alone cannot meet the requirements for traffic scheduling, and it is complicated.
Most of them are based on the traditional way (SNMP collection and manual command-line positioning), the degree of network automation is low, and the popularization of automation technology is slow.
Most rely on manpower for network maintenance, and the efficiency of emergency handling and troubleshooting is low.
The business traffic path of backbone network is visible. It is easy to track and check the bandwidth and path occupied by the real-time business. Traffic can be scheduled on demand to flexibly meets the requirements for various business scenarios in a financial backbone network, such as fast and flexible traffic scheduling in case of emergency and bandwidth overrun.
The backbone network protocol is simplified, and a multi-service and multi-user network is realized to help enterprises develop business.
A new generation core network is constructed based on SDN concept, and driven based on the control layer and customers' upper-layer applications to rapidly deploy services.
