This document discusses wide area networks (WANs) and application delivery. It describes various WAN technologies like IP-VPN, Ethernet, and Internet VPN that can be integrated into a single network. It also discusses modern applications like web, databases, and VOIP that organizations want high performance for over WANs. However, applications are often not optimized for WANs and can experience issues due to protocol inefficiencies, traffic bursts, and latency. The document recommends using WAN acceleration to improve application performance, reduce bandwidth usage, enable centralization of services, and provide LAN-like performance for remote access users. It discusses how WAN acceleration can solve problems organizations face with high WAN utilization, inconsistent application

‘killing’ for applications via WAN
Duplicate Data
E-mail with file to multiple users at remote office
Virusdefinitions
Windows updates…
Inability to utilize bandwidth
The link is 10Mbps but almost empty
Latency
It takes forever to open or download a file
The document should open within 10 seconds, but…
Applicationresponse
The next screen takes forever…
Data Center replication and backup
Replication takes forever
Backup does not finish within the backup window
Remote Access
Why is it so much slower than at the office?

What does it solve?
Improve application performance
Significant performance improvement of wide range of applications
Improve performance of badly written applications
Consistent end-user performance
Reduce bandwidth requirements
Solution for locations where bandwidth is expensive or not available
Cost reduction, WAN upgrade not necessary
Centralization of services
Reduce license and management costs
Improve manageability
Prevent version issues (building design, contracts, etc), high risk, significant loss
Reduced TCO
LAN like performance for Remote Access users

What does it solve?
Client updates without performance impact
Windows patches
Virus updates
Software updates
VDI, thin clients
Support more users with same bandwidth
Guaranteed and consistent performance
Data center replication
Ensure data is replicated within time-window
Use of high latency or low-speed links without performance impact
Reduce WAN costs
Version control
Centralize datastore, one version!

Provisioning
Select the right solution!
Always perform a Proof of Concept
Alternative is Buy & Try
Buy as a service (example cloud apps, SAAS)
As part of the WAN service

Remember, if you have these problems:
High-utilized links
Costly WAN
Inability to utilize high-speed links
Application performance issues or inconsistent performance
Badly written applications
Version management issues (contracts, designs, etc) which can cause major loss
or law-suits
Distributed environment with high management and license costs
Requirement for updates (software, patches, virus) but no bandwidth to
support it
Inconsistent performance of thin clients (RDP, Citrix)
Requirement for disaster recovery over low bandwidth or high latency links
Remote Access performance issues
Off-site backup over low bandwidth or high latency links
