Application performance improvement

Application performance can be impacted for a variety of issues. Congestion, WAN link performance (such as, high latency, jitter, or packet loss), server issues, routing changes, and other network issues could all be detrimental to performance and user experience. The FortiGate SD-WAN solution incorporates a number of techniques and capabilities to improve application performance for a variety of deployment methods.

• Application identification and steering: Performance SLAs check all available paths to the application to determine the best performing link. Potential network issues can be detected in sub-second speed and steered to a better performing link based on the business requirement.
• WAN Remediation (Packet loss correction): There are situations were protecting the application from packet loss is crucial to business continuity. WAN remediation refers to a series of techniques to fix packet loss on a WAN link. Forward Error Correction (FEC) and Packet Duplication are WAN remediation techniques that can be used to protect a link from various types of impairments.
• QoS (Quality of Service): Because bandwidth is finite, sometimes it is necessary to prioritize how traffic is distributed based on business needs. FortiGate SD-WAN allows you to police, shape, and queue network traffic at each location. Adjustments can be made automatically, depending on available bandwidth at certain times of the day.
• WAN Optimization: WAN optimization is a comprehensive solution that maximizes your WAN bandwidth and improves user experience. Some techniques include protocol optimization, web caching, explicit proxy, byte caching, and more.
