With the rapid development of information technology, LAN and WAN solutions have now become the most critical part of the normal network connection and efficient communication of many enterprises and families. Speaking of LAN, we often hear and see the local area cafe mentioned. It mainly enables some connections and communication between devices within a limited geographical range, such as office buildings, school classroom buildings, and other environments, so that office machines and students in the same area can be connected to the Internet.
And this so-called WANLAN/WAN Solutions is the full name of WANLAN. Compared with the local area network, it will cover a very wide geographical range, like a city or even across cities. It can communicate and connect various LANs or isolated systems far apart, such as cables or optical fibers through wired lines, and wireless methods.
Generally speaking, let me talk to you about the key benefits of two more recognized solutions. First, let’s talk about the important and positive aspects of this LAN solution;
1. It can efficiently make sharing smooth office resources: it is normal for office workers to have a large number of file resources and printing equipment. In this case, if you have a high-quality LAN solution, staff can share and share equipment resources to save economic costs and also facilitate the full use of equipment;
2. Then achieve fast and accurate data transmission: LAN provides stable and ultra-fast data lines. Operations in large enterprises require data exchange. It can quickly and efficiently transmit information back and forth and keep the business orderly.
Let’s take a look at the positives of this WAN solution;
1. The long-distance network can be connected continuously and stably: no matter where you do foreign trade business, technology research and other businesses, no matter where the company branches to the end of the world, as long as it has a reliable set of countermeasures, the branch structure and headquarters can always maintain close communication. Let the business continue as expected without being troubled by distance.
2. Realize global synchronization of information: it is indispensable to connect the international network of foreign economic and cooperative trading companies. WAN solutions just solve this dilemma through backbone network or Internet access to ensure the integration of domestic and international information resources.
We all often confuse this LAN. In addition, the two ideas of WAN are used in specific use, let me tell you why most companies choose to build these two solutions at the same time?
You see, if you build a LAN, the enterprise can first more effectively and safely manage the communication operation of the entire area. However, if it is used alone, it will definitely have limitations. For example, it is difficult to maintain communication with other regional units and it is difficult to reach all parts of the country. In this case, enterprises must deploy wan and expand their own businesses to advance. In this way, the wan solution is to use the wide area network to connect all areas that have been built into LANs to the same system so that enterprises can operate globally and globally. You can think about it in this way and assume that the LAN is a "solid city wall" and protect it from maintaining regional integrity within a single castle; that's easy to use as a metaphor. This wan should be more similar to the "bridge corridor". No matter how far apart the castles of each LAN architecture can "walk around, communicate and communicate with each other, etc.
Enterprises must be cautious when choosing these two different but crucial solutions. You can ask which service providers have been doing it for a long time, whether the price is appropriate, whether the technology is advanced, etc. First of all, you must know that the business scope of different companies is different. The business development directions are different. The solutions are suitable for this. Therefore, when companies conduct inspections and evaluations, they should pay more attention and never just look at the cheaper ones. Don’t worry about the long-term operation and maintenance, or whether the supplier’s technical strength is strong, etc. If you do not measure it well, it may cause troubles or the efficiency will be greatly reduced, which will cause unexpected negative consequences to the company’s economic and business progress, which will be so serious. This involves key technical aspects. It is necessary to find professional strong manufacturers or partners. For example, some large brands or service providers have reliable network equipment technology and reputation, and their after-sales service is more energy and capital to do well. Can solve some problems faced by enterprises in a timely manner, etc.
Speaking of choice, some service providers and even business owners still have to think about the compatibility of corporate office software. Is it suitable for various operating systems? It is necessary to be compatible with a variety of environments. Common operating systems such as common, macOS, various Linux variants, etc. to avoid normal network performance degradation or even interruption due to access inadequacy. Enterprises should choose the kind of fully compatible devices and configuration methods that are suitable for various systems. In terms of protocol selection, the protocol specifications must be carefully considered based on the international common mode to select mainstream TCP/IP protocols or SSH protocols, SSL, and VPN modes involving data security encryption.
In addition, some companies in special working conditions will definitely pay more attention to security and compliance and security issues, and must implement strict filtering of data access. Enterprise data is definitely afraid of unintentional leakage, etc., causing unnecessary losses; in view of this, it is very important to protect the security and stable operation of enterprise databases through access control, setting permissions, etc. In some other cases, the data encryption process needs to be carried out during the transmission process. The encryption strategy must ensure the stability and integrity of communication while resisting external "peeping". This is especially true for some government-specified data information.
The decision to choose network bandwidth is very critical to the successful activation of the solution; it is necessary to make decisions based on the estimated data traffic of the organization's existing work. If the bandwidth is set too much in a small network system, it will cause meaninglessness and "burn money". Conversely, if the access is too small for large institutions, the business will be often busy during work and the node congestion will eventually be paralyzed. Load balancing strategies for different nodes are also a key measure to measure the distribution and deployment of services. Through the combination of cloud platform technology, network cluster mode and other means, each server can reasonably divide the labor and take on the corresponding work without causing a key "brain center" type of computing or communication "traffic jam". This is also a very test of the team's computing strategy level and scientific system setting capabilities.
Finally, I want to say that in the increasingly complex and changing network, the perfect integrated collaborative application of LAN and WAN is not only the basis for enterprises to achieve stable operation but also an important step in helping to move towards modernization and global development. The delicate and stable LAN built by LAN is like a home decoration environment to provide employees with a warm and comfortable operating atmosphere, and high-performance and powerful support. The WAN system is a company that keeps going out to "go out of the home and break into the vast world. Tools and means to pave a smooth road for its own external contacts. Whether you are rooted in a small city studio or a world-renowned multinational enterprise, they can be said to be an important "pack" necessary for survival and operation.
