It is imperative that companies build their business networks in a way that minimizes bottlenecks in private lines, allowing existing links to handle more business traffic. This improves application access speeds over private lines and means higher cost effectiveness and backup bandwidth for private lines.

 

Why Optimize Private Lines?
Enterprises are constantly growing and continuously adding new branches, increasing the need to send network business data between branches and headquarters. As such, many enterprises and industry groups use private lines to build a proprietary business network. However, increasing branch connections and business systems make these private networks ever larger and network access slows down. In cases like this, most business owners rented higher bandwidth private lines. But renting private lines is expensive, and some business application systems cannot be effectively improved merely by extending bandwidth.

 

Businesses need a solution that will effectively decrease traffic to private lines. By improving the utilization of private lines, networks can use lower bandwidth (lower cost) private lines to achieve the transmission effects of higher bandwidth (higher cost) private lines. This can also be a backup solution for private networks, with quickly encrypted data transmission, so that companies can balance cost, efficiency, and information security.

 

Problem with Private Lines
Private lines are highly stable network lines that are capable of fast transmission, however, the private lines are expensive. The key to efficiently resolving the conflict is to decrease data interaction and data volume carried on the private lines.

In addition, most enterprises and business teams are consolidating their data storage and access. If private lines fail, the costs of data loss and disrupted business can be nearly unimaginable. Enterprises absolutely must utilize backup lines to avoid this potential disaster. Companies require a more effective and economical solution to address the following problems:

As the graph above shows, deploying SANGFOR WAN accelerating devices at the headquarters and branches of private line networks can effectively lower the rate of private lines traffic congestion, so that private lines can carry more application traffic, enabling smoother business access.

 

In order to guarantee reliable data backup at headquarters as well as backup data centers, enterprises can deploy SANGFOR’s WANO products at headquarters and branch sites, forming a fast VPN backup link for private lines and optimizing traffic at the same time.

 

SANGFOR’s WANO products optimize private lines’ traffic and Internet through the following approaches:

Data optimization: Benefit from industry-leading data reduction of Byte-caching technology, SANGFOR WANO can eliminate from 30 to 90 percent of data traffic on transmission lines. It can also maximize data transfer with GZIP/LZO stream compression. The combination of reduced data, and compressed data, Frees up the bandwidth and alleviates the need or frequency of bandwidth upgrades.

 

Transmission optimization: SANGFOR’s WANO products improve TCP transmission efficiency via selective response, window processing mechanism optimization, congestion control optimization, and other methods, and can further improve the responsiveness of business applications.

 

Protocol optimization: For application-layer protocols that require a lot of response and acknowledgment (such as CIFS) SANGFOR’s WANO products use proxying to decrease application protocol interaction and improve transmission speed.
