Quality of Service (QoS)

Generally speaking, Quality of Service (QoS) refers to control mechanisms to provide better service to selected network traffic, and to provide priority in terms of guaranteed bandwidths in particular. In Sophos UTM on AWS, priority traffic is configured on the Quality of Service (QoS) tabs, where you can reserve guaranteed bandwidths for certain types of outbound network traffic passing between two points in the network, whereas shaping of inbound traffic is optimized internally by various techniques such as Stochastic Fairness Queuing (SFQ) or Random Early Detection (RED).
