What defines an SD-WAN built with NetScaler?

An enabler for corporate strategy

Highly reliable

With abundant

bandwidth

And providing

direct access to

cloud

It is application

Even MPLS often lacks the reliability that enterprises

need

And cloud connection using Broadband have even lower

reliability

Reliability is a challenge with any type of connection

The Danish Agrifish Agency vessels had separate 4G/LTE connections from different mobile providers, but coverage was not consistent and applications would disconnect or perform poorly when the links become degraded or failed.

Why they selected NetScaler SD-WAN

• Solution enabled applications to seamlessly migrate among mobile connections without disruption or sacrificing security

• When one link failed, applications immediately were moved to remaining best link

• QoS capabilities ensured that mission critical data was prioritized over other applications.

Results

• Uninterrupted connectivity• Centralized management GUI

• Improved throughput

Rehab Management needed more bandwidth for XenApp and XenDesktop and training videos than was available on MPLS


• NetScaler SD-WAN solution would allow them to replace their MPLS connections with just their existing Internet (ADSL) access giving them 10x the bandwidth at a lower cost

Results

• By making all links active, achieved the bandwidth they needed for XenApp and Training videos

• Reduced costs from $500/month/location to $100/month/location by switching to ADSL lines

• Using multiple links also improved reliability

Orianna needed a new electronic medical record (EMR) but increasing bandwidth would cost an additional $500/site/month


• Bonded a broadband link with existing MPLS circuit

• Avoided $300K/yr. increase of network capacity upgrades with NetScaler SD-WAN by bonding MPLS & broadband links for better use of existing bandwidth

Results

• Received ten month payback on the purchase versus scaling existing MPLS connections

• Were able to rollout EMR immediately instead of waiting 90-120 days for MPLS upgrades

• Instant failover at remote sites achieved better application reliability and QoS on VoIP
