Quality of Service
Prioritise critical network traffic when shared links are congested.
Overview
Voice, video and interactive applications can perform poorly when links are busy. Large transfers or non-business traffic may consume bandwidth needed by critical services, while inconsistent treatment between sites makes it difficult to decide which traffic should take precedence. These issues often become more apparent when new sites, remote users or cloud services add demand to WAN links.
Quality of Service defines traffic classes based on application requirements and business importance. It applies consistent classification, marking, queuing and rate controls across relevant network paths, so priority traffic receives defined treatment during congestion and bandwidth-intensive traffic can be limited where it affects critical services. This reduces first-come, first-served handling and ad hoc responses to recurring contention.
What this solution helps you achieve
Controlled bandwidth use
Bandwidth-intensive traffic is limited to protect priority services during congestion.
Predictable application performance
Prioritised applications remain responsive when competing traffic causes congestion.
Prioritised WAN capacity
Critical applications receive appropriate WAN capacity during busy periods.
Consistent traffic treatment
Traffic classes and priority treatment are applied consistently across relevant network paths.
