1, the requirement analysis of WAN construction

With the rapid development of cloud computing technology and Internet of things technology, the continuous development of network business applications, all kinds of new applications continue to emerge. And it is becoming more and more important in the process of enterprise business development, which makes it more and more common to build and operate multiple business networks within the enterprise. On the other hand, The characteristics of cloud computing determine that the large enterprise network architecture must gradually develop from the original decentralized construction and deployment model to centralization and scale.Business system centralized scale is deployed in the cloud data center. It has become the mainstream mode of large-scale enterprise network construction to provide data service for multi-organization nodes across regions and to realize data concentration at the same time.


Under this background, the construction of wide area network (WAN) is becoming more and more important in the process of enterprise IT construction. Because of the high cost of link construction, how to better realize multi-connection and multi-service bearing under the premise of limited bandwidth. To improve the efficiency of link resource utilization, improve the network application experience, and build an intelligent and reliable wide area network (WAN) has become the main goal of WAN construction.


The main requirements of WAN construction are as follows:

The wide area network (WAN) undertakes the function of interconnection between the headquarters and branches of the enterprise as well as between various departments. As more and more applications are carried on the WAN, security threats also follow, and illegal access occurs. The proliferation of malicious code has become increasingly prominent. How to ensure the connectivity and reliability of the network at the same time to ensure the security of WAN and meet the requirements of relevant laws and regulations?

In WAN, MPLS technology is widely used to isolate between services. MPLS VPN network requirements and dynamic routing protocol requirements are common in WAN. Make most security devices unfit. How to deploy security products in a complex WAN network environment for security protection and auditing?

Traditional WAN boundary deployment uses Tomatoes on sticks string mode, routers, firewalls, intrusion prevention / detection, security auditing, traffic management, Load balancing and other products have caused a large number of single point failures. How to meet the security requirements of WAN without reducing network reliability?

Due to the continuous increase in the number of users carrying the network, there have been many problems of bandwidth abuse. The misuse of bandwidth by P2P IP and other protocols causes the bandwidth of critical services (such as videoconferencing) not to be guaranteed. How to make full and effective use of WAN bandwidth so that the bandwidth of critical services can be guaranteed?
