First, the traditional network operation and maintenance method pain points

Manual maintenance of network equipment relies on traditional network management software to assist manual maintenance. The operation and maintenance efficiency is low. It is easy to cause the efficiency of operation and maintenance and increase the cost of operation and maintenance due to differences in personal capabilities and response.

The traditional network service cutover or new service uplink cycle is too long, and often large service cutover handover involves very complicated operations. For example, the firewall device involves multiple policy adjustments and has a high probability of error.

The traditional network fault location is not efficient enough, and some problems are difficult to locate. It is often because of the engineer's personal experience and ability, which affects the progress of the fault processing, which ultimately leads to serious consequences and increases the burden of operation and maintenance.

Second, the difference and advantages of SND operation and maintenance

The main feature of the SDN network is clustering, using virtual software to define network data streams, and simple presentation in a graphical manner, facilitating the on-line and post-maintenance expansion of services.

SDN automated operation and maintenance mode, docking with the cloud platform to achieve automation of network services. Real-time automatic optimization and sensing of traffic paths and network congestion, accurately sensing network latency and packet loss. At the same time, the configuration of the replacement spare parts is automatically delivered, which improves the operation and maintenance efficiency and avoids errors caused by human operations, thereby increasing the cost of operation and maintenance.

In the SDN operation and maintenance process, the physical network structure and the logical network structure can be clearly combed through a visual graphical interface, and the service flow and management data flow can be understood at a glance. The SDN radar detection network fault, SND simulation terminal mode simulation data test, etc., through the visualized page, the network maintenance work can be carried out simply and clearly, and the operation and maintenance of the traceable and auditable specifications can be realized.

The network operation and maintenance changes brought by the SDN architecture change are also very large. The overlay-based network uniformly accesses services, manages, stores traffic, and eliminates the Layer 2 loop of the basic network. The network structure of the entire overlay breaks the traditional network barriers and enables the interconnection and interworking of the remote data center. In the operation and maintenance process, you can use the graphical interface to uniformly schedule and maintain service data in the network to implement loop detection, path detection, and switch service flow. The operation and maintenance is convenient and fast.

Intelligent, visual, and automated, is the main way to run and maintain the SDN network in the future, reducing the cost of traditional network maintenance and improving the efficiency of network operation and maintenance.
