Performance of an applicationacross the WAN is always dependent on the latency.
Calculating Throughput
The equation never asks for the bandwidth size!

APPLY 1 OR ALL 3 TECHNIQUES
THE SOLUTION
• NETWORK INTEGRITY
• FIX CONGESTION / PACKET LOSS• • Traffic Shaping/Quality of Service (QoS)
• • Forward Error Correction (FEC)
• Packet Order Correction (POC)
• NETWORK MEMORY
• INCREASE BANDWIDTH• Real-Time deduplication of all IP traffic
• TM
• NETWORK ACCELERATION
• EXTEND DISTANCE• Mitigate protocol latency and chattiness

ELIMINATE PACKET LOSS

Packet Lost
Lost Packet Rebuilt from Parity
• Parity dynamically adjusted based on amount of loss
• Lost packets rebuilt at the receiving Silver Peak
• Receiver unaware packet loss has occurred
• No window size decrease

CORRECTING OUT-OF-ORDER PACKETS
1234
1234
• Packets are tagged as they leave the Silver Peak
• Out-of-Order packets are reordered at the receiving side
• Receiving client unaware that out-of-order packets have occurred
• No window size decrease

WHAT DOES IT REALLY MEAN?
LAYER 4-7
LAYER 3• Set & forget - Optimize ANY & ALL traffic• Fix network health issues, accelerates & deduplicates• Optimization is 100% independent of the application or version
• Only optimize specific set applications
• Coordinate software upgrades with WANOP appliance version to avoid breaking applications and optimization
• Unsupported applications can break

DATA REPLICATION SHORTFALLS
• Are you consistently meeting your RPO?
• Are you having capacity problems?
• Is all of your data protected?
• Would you like to increase the distance between sites?
FOUR QUESTIONS…
Strictly Confidential | © 2013 Silver Peak Systems, Inc. All Rights Reserved.
DEFINITIONS
• Recovery Point Objective (RPO)o How much data can you afford to lose?
• Recovery Time Objective (RTO)o How much time before you are up and running again?

REMOTE REPLICATION CHALLENGES
Latency Quality Capacity
Latency (distance) decreases the amount of data that can be sent
across the network
Network errors such as packet loss and out-of-order packets slow
replication throughput
Insufficient network size (capacity) limits the amount of data that can
be replicated over distance
