The Long Distance Problem LAN WAN Throughput Average Utilization Average Utilization Time Slow Start Slow Ramp Contributing factors to poor performance Latency Congestion Small transmission window size 15
Traditional Approaches Branch Office Experiences Slow Application Response Time Branch Office Upgrade to More Bandwidth Headquarters Data Center Result: Expensive Applications Still Slow Doesn t Scale 16
What Causes Poor Application Performance over the WAN? Network latency (distance) The greater the distance, the worse the application performs Bandwidth utilization drops exponentially as Accessing E-mail in Seattle from a distance increases server in Orlando can take up to 80 times longer than from a server in the same building! In the same city San Francisco to Los Angeles San Francisco to Chicago San Francisco to Miami 17
Symmetric vs. Asymmetric Performance Symmetric Repeater Asymmetric 5x 100x 2x 8x NetScaler Non HTTP traffic: Protocols & Applications CIFS, SMB, FTP. Big files or large amounts of data being transferred Client-side Control Do you have a presence on the far side of the WAN? Yes, Enterprise deployment Primarily HTTP & HTTPS No control over the client s side of the WAN Clients are B2B or B2C 18

Application Optimization on the WAN The Symmetric Solution
Symmetric vs. Asymmetric Performance Symmetric Repeater Asymmetric 5x 100x 2x 8x NetScaler Non HTTP traffic: Protocols & Applications CIFS, SMB, FTP. Big files or large amounts of data being transferred Client-side Control Do you have a presence on the far side of the WAN? Yes, Enterprise deployment Primarily HTTP & HTTPS No control over the client s side of the WAN Clients are B2B or B2C 28
Traditional Approaches Branch Office Experiences Slow Application Response Time Branch Office Upgrade to More Bandwidth Headquarters Data Center Result: Expensive Applications Still Slow Doesn t Scale 29
The Citrix Repeater Solution Maintain/Reduce the Current Bandwidth Support More Users Branch Office Communicate with More Branch Offices Extend Performance to Mobile Users Headquarters Data Center Mobile Users Result: Cost-Effective Simple Scales 30
Citrix Repeater Solution Headquarters Branch Repeater Repeater A symmetric, network acceleration solution A site-to-site appliance and software, for datacenters, hub sites, remote offices, home or mobile users. An instance of Repeater required at each location Accelerates Data over WAN links Transparent Device TCP Flow Control Acceleration Multi-Level Data Compression: Adaptive, Toeknized Protocol Acceleration: CIFS, ICA 31
Tunnels Complicate the Network More difficult to install Higher ongoing IT maintenance costs Proprietary Tunnel Non-Citrix WAN Op Non-Citrix WAN Op Datacenter Branch Office Users 32
Repeater is Transparent No network reconfiguration Lowers deployment and maintenance costs Repeater Repeater Datacenter Branch Office Users 33
Adaptive Compression Not a one size fits all solution Very Efficient Not the right compression Compression algorithm! Try Another! Maximum Reduction = Faster applications 34
Multi-Level Compression: Tokenization Not a one size fits all solution Bandwidth Savings 35
Application Acceleration Example: CIFS 250ms 250ms 250ms 250ms 1000 ms 125ms WAN Latency 36
