A financial company to realize off-site office network interconnection solutions

Customer background:

A financial company is headquartered in Shenzhen and has a branch in Shanghai. With the growth of business volume, the exchange and communication between employees in the two places are becoming more and more frequent. In view of this situation, the head office decided to upgrade the network through the network to connect the two places. This financial company has a total of 80 employees in the headquarters in Shenzhen, divided into five departments, and the Shanghai office has a total of 30 employees, there is no departmental division, and we hope that we can build a network upgrade program on this basis.

Challenges:

Physical Layout: Consider the physical locations and distances of the off-site companies and determine the network connection paths between each location. This may involve the use of different connectivity methods such as dedicated lines, VPNs, Internet, etc.

Bandwidth requirements: Evaluate the bandwidth requirements for each location and ensure that the network topology is capable of meeting those requirements. Determine the bandwidth size of the network connections based on business needs and expected data traffic magnitude.

Network equipment: Determine the network equipment that needs to be deployed at each location, including routers, switches, firewalls, and so on. Consider the models and specifications of the devices and how they will be connected to each other.

Redundancy and Reliability: Design a network topology with redundancy mechanisms, taking into account the reliability of the network connections at the off-site locations. Use techniques such as backup links and dual-router deployment to ensure high network availability.

Security: Consider security in the network topology design, including the deployment location and configuration of security devices such as data encryption, access control, and firewalls.

Solution:

In order to meet the work communication and file transfer between employees in two places, we connect the branch network to the headquarters through ospf technology combined with 2 firewalls, and set up routers in the branch area (area0) for access layer connection, and set up servers and core switches in the headquarters area to realize the networking requirements of PCs in each department.
