7 Ways to Improve Efficient Networks through WAN Optimization


Applications are a lot smarter today while the bandwidth is much cheaper. Can you blame anyone for thinking that revamping the Wide Area Network is one of the unnecessary expenses? In the current world that is obsessed with embracing hybrids and WANs and clouds, the optimization is a lot more relevant now, than it ever was. Here are the top seven ways that you can improve efficient networks with the help of it, and they are mentioned down below.

WAN Optimization


Recovering lost packets and correcting the packet order

Recovery of lost packages and the correction of forwarding error ensure that the data is reliably delivered. This is one of the essential WAN Optimization techniques that improve not just the quality of links but enhances application performance. Furthermore, this single step also accelerates the transmission control protocol (TCP). After there has been the recovery of the lost packets, correcting the order of the packer on the fly helps in avoiding impacts of negative performances as well as retransmissions because of packages that went out-of-order.

Selection of path and service quality 
To maintain service quality, deeply inspecting the packet and classifying it is necessary. Therefore, WAN Optimization marks and shapes the traffic to ensure priority of business and that bandwidth-intensive traffic receives optimal service quality. This method is followed by balancing the load of the traffic over multiple gateways of WAN by setting layer-7 policies of traffic and link-metric thresholds.

Universal de-duplication and accelerating the TCP
Cross-flow de-duplication helps in removing the duplicate patterns of byte regardless of the protocol at the source. It eliminates the byte patterns irrespective of session or application that originated because of the data at the start. It saves the byte patterns persistently on disks for network matches in the future. The fully transparent performance of TCP acceleration enhancing proxy (PEP) significantly improves the performance of TCP with a TCP of high speed. 

The firewall in Layer 7
On deep inspection of the packet, the process filters traffic and the application signatures at the edge of the branch.

Bridge appliance and tunnel mode 
Some optimizers bridge appliances by default. They enable quick and straightforward deployment. Furthermore, they are also non-intrusive and thus preserve the flow of natural traffic. The mode of the tunnel, on the other hand, compliments the bridge mode as a flexible and alternative option of deployment to route the traffic. It is achieved through optimizers.

Transparency of network and analytics of Netflow
Open-Source Linux powers the interface of web and provides visibility into the optimizer’s performance. It also provides visibility into the configuration options, information of system health, and protocol statistics. The optimizers maintain transparency of network where for the clarity of network, destination, and source addresses are preserved. It never translates proxy traffic or addresses.

Compression of the stream 
Stream compression of network data on the move in real-time, for higher ratios of compression helps to improve the network efficiency. Such a compression helps with savings of bandwidth and acceleration that further prioritizes traffic.
