How Wan Acceleration Works

Are you wondering why business organizations require wide area network optimization? These techniques are utilized for boosting the efficiency of data transfer across the wan platform. It involves prioritization of traffic, so your organization does not have to purchase expensive bandwidth. With the advancement in applications, other technologies and cloud computing the importance of wan optimization have grown steadily. The process of installation is simple, and then you can forget about the entire matter and let these techniques operate on their own without much intervention of the IT department.

Some causes

You may be dying out of curiosity to know how these techniques perform their magic. Then at this juncture, it is essential to know about the major causes which are responsible for performance problems. Take a peek at the website of wanos, and you will come to know about practical wan acceleration solutions. 

•    Latency aspect

You may have come across the term chatty protocol which is nothing but the transfer of messages to and fro generally among clients and servers. Such chatty protocol fails to act efficiently on wide area links. The entire process involves the sending of packets by the server and then placing queries to other servers to know if they have received it. In this manner, a single file comprising of a couple of bytes will end up taking a sizable chunk of time. You can overcome latency issues through the implementation of wan acceleration solutions such as quality of service techniques.

•    TCP window

Your dismal network performance may often be attributed to your TCP window size. The transmission control protocol was discovered in that era where network speed was extremely slow. The networks in recent times have undergone major changes, and they have become way too faster. So if the packets are not received properly some or all of them are required to be transmitted again. If the network is not reliable, then the TCP window has to be kept small.  TCP acceleration is an effective technique.

Prevention of resending redundant data

The reputed companies who are providers of wan solutions make use of a process called data deduplication. This procedure involves removal of bytes from the network. Frequently accessed data are not resent several times. Instead of that references are sent. In recent times, transport streamlining is introduced. This technique increases the efficiency of TCP. This technology searches for the optimal packet size instead of going through the process again and again. Application streamlining has also grown in importance because the modules operate together to keep the chattiness confined within LAN.

Make the selection carefully

You should select the wan service provider carefully. The company you choose should offer you alternative routes so that any failure in one connection will reroute the traffic to another connection automatically. Make sure to find out if there is a secondary network available in case of failure of the primary one. Network security is a complicated area, and you have to be confident that the service provider you have chosen can provide adequate network protection and adhere to the industry regulations.
