Implementing Practical WAN Quality of Service
To provide global users with smooth application performance over the WAN, Intel IT researched and implemented a Quality of Service (QoS) capability that controls flow and prioritizes data handling to improve overall WAN application performance as well as prepares for Voice over IP (VoIP). Applications are adversely impacted when congestion causes packets to be delayed and/or dropped, and congestion from several applications running simultaneously can quickly become problematic if not properly managed. QoS technology can improve network performance for WAN applications, particularly with high-bandwidth applications such as VoIP and video. QoS won't eliminate the congestion; however, careful implementation can limit the impact of congestion to those applications least affected by it.
