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.
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.
