Today’s WAN Challenges are Different

Bandwidth demands within the enterprise are increasing at 15% per year

Businesses are transforming faster than ever, and network agility is key to keeping

pace

Multi-protocol label switching (MPLS) was never designed with SaaS and cloud apps

in mind

With more applications moving to the cloud, WAN reliability becomes key to

business continuity


And often lacks the reliability that

enterprises need

The WAN is the Most Expensive Part of the Enterprise Network

Not only is MPLS expensive, but:

• The timeframe for MPLS adds/moves/changes is 90 days or more

• Often requires multi-year contracts

• Limits local support independence

MPLS Pricing vs Broadband in the U.S.


Business Case for a North American Enterprise

$500/month1 Mbps MPLS

$95/month10 Mbps DSL

$1,300/month10 Mbps MPLS

Example customer with:

• 50 branches / 2 data centers

• 1 Mbps today; Need for 10 Mbps

• Two options:

1. Grow MPLS to 10 Mbps

2. MPLS plus broadband

• Three-year savings of ~$800K by using SD-WAN


Beyond Cost Savings, NetScaler SD-WAN Improves Availability

Skilled Nursing Facilities Operator with 49 locations

Challenges & Opportunities

• Established XenDesktop customer with 49 remote locations connected with MPLS

• New electronic medical record (EMR) project required immediate bandwidth upgrades, but MPLS was expensive ($500/site/month to increase to 10 Mbps)

• Needed reliable, effective connectivity for remote locations

Why NetScaler SD-WAN

• As an existing customer, Citrix is a trusted solution provider, and customer saw the benefits of a “Citrix on Citrix” approach

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

Results

• Ten month payback on the purchase versus scaling existing MPLS connections

• Immediate EMR rollout instead of 90-120 days for MPLS (circuit) upgrades

• Instant failover/DR at remote sites for better application reliability & VoIP QoS


Large File Transfers

• Path selection = assign application traffic to the best path

• Path bonding = leveraging multiple paths for application traffic

• NetScaler SD-WAN provides both…other solutions don’t

• Reduces WAN bandwidth requirements by up to 80%

• Preconfigured QoS settings ensure correct prioritization of HDX traffic

• Supports both single-stream and multi-stream deployments

• And optimizes other enterprise applications as well

NetScaler SD-WAN Benefits for XenDesktop


The challenge:

• Single Data Center supporting multiple branch office locations with:• MPLS @ 1.5 to 3 Mbps depending on branch size

• Separate Internet access connection for customer Wi-Fi

• Data center hosted Citrix and other enterprise applications

• Issues: • Poor application performance

• MPLS network was a single point of failure

• Inability to use all of the available WAN bandwidth

MPLS


With the NetScaler SD-WAN solution:

• MPLS and Internet bandwidth shared across employees and customers

• No single point of failure for a particular application

• XenApp traffic can be prioritized and minimum bandwidth reserved, maintaining application performance even when network is congested

• Improved application performance through bandwidth scalability

• Increased efficiency by printing offload from MPLS bandwidth
