Every organization is becoming heavily dependent about
delivering IT applications efficiently. Early adopters WAN optimization
companies are always on the lookout of vendors that can take responsibility and
make needed improvements in the networking infrastructure that exists. They
must be able to achieve agility in business and be extra responsive to changes.
Providing an optimal user experience around delivering services and
applications is equally important. While many have solutions that are piloted
yet, there are capabilities and requirements that you must look for in a
vendor. The tips are listed below that should help you.
1. De-duplication universally
Your wan optimization vendor should allow de-duplication of cross
flow just like Wanos Networks. This cross de-duplication should in turn help in removal of
byte patterns. It should be irrespective of all the data that originated during
sessions, applications, and source protocols.
2. Recovery of Packet loss
Your wan optimization vendor should be able to keep an accuracy
of the RTT of all the wide area network links. This shall help in recovering
and detecting early losses which shall ensure delivery of data reliably.
3. Service quality
The seller should always be able to provide optimal quality
of duty. This service is regarding quality regarding marking, classification
and shaping traffic which further ensures priority.
4. Correction of packet order
To avoid negative performance correction of a packet is a
must. This shall stop retransmissions when packets are out of order.
5. Acceleration of TCP
Your trusted seller should have a proxy for performance
enhancement. This proxy can enhance the performance of the TCP resulting in
high speed.
6. A data store that is persistent
Your vendor should be able to provide data based on large
disks that enable de-duplication. It should also facilitate retention of long
term data and restoration of full service after an outage of infrastructure.
7. Appliance of the Bridge
Your optimizer of wide area network should be able to enable
simple and quick deployment. It is also non-intrusive and helps in the
preservation of traffic flow naturally.
8. Transparency of the network
There should non-transparency of the network that must be
provided by your seller regarding destination and source addresses. A good
optimizer vendor must never translate proxy traffic and addresses.
9. Router Mode
A tunnel or routed mode always compliments the bridge mode.
Your optimizer must have options for flexible deployment to route traffic.
10. GUI
There should be an interface of the web that must provide
visibility into the optimizing performance of the wide area network. The GUI
should also be able to provide visibility into protocol statistics and
configuration options.
A strategic host
The optimization of wide area network has its evolution from
being tactically deployed to being a strategic one. Improving the utilization
of network and performance applications are the most relevant considerations.
These factors must always be taken into account while planning system wide
deployment strategically. Hence these tips mentioned above should be of great
help to you for selecting the right vendor. This is because when you integrate
existing platforms of network and interoperability with other services, it
shall lead to the strategic scenario of deployment. It is all vendor-specific,
and you must be associated with the right vendor. You aim must be directed
towards consolidating remote infrastructure of sites and improving
productivity.
