FortiOS WAN optimization.
Organizations with multiple locations or businesses using the Cloud can provide license-free WAN optimization using FortiOS.
WAN Optimization is a comprehensive solution that maximizes the WAN performance and provides intelligent bandwidth management and unmatched consolidated security performance.
WAN optimization reduces the network overhead and removes unnecessary traffic for a better overall performance experience.
Efficient use of bandwidth and better application performance will remove the need for costly WAN link upgrades between data centers and other expensive solutions for the network traffic growth.
WAN optimization is available on FortiGate models with internal storage that also support SSL acceleration.
Internal storage includes high-capacity internal hard disks, AMC hard disk modules, FortiGate Storage Modules (FSMs) or over 4 GB of internal flash storage.
WAN optimization tunnels use port 7810.
The following features below are available through WAN optimization:
Protocol optimization is effective for applications designed for the LAN that do not function well on low bandwidth, high latency networks.
FortiOS protocol optimization improves the efficiency of CIFS, FTP, HTTP, MAPI, and general TCP sessions.
CIFC, for example, requires many background transactions to successfully transfer a single file.
When transferring the file, CIFS sends small chunks of data and waits sequentially for each chunk’s arrival and acknowledgment before sending the next chunk.
This large amount of requests and acknowledgements of traffic can delay transfers.
WAN Optimization removes this complexity and improves the efficiency of transferring the file.
TCP protocol optimization uses techniques such as SACK support, window scaling and window size adjustment, and connection pooling to remove common WAN TCP bottlenecks.
Regular bandwidth usage.
