In [[computer networking]], a '''reliable''' protocol is a [[communication protocol]] that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for '''assurance''', which is the term used by the [[ITU]] and [[ATM Forum]], and leads to '''fault-tolerant messaging'''.

In [[computer networking]], a '''reliable''' protocol is a [[communication protocol]] that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for '''assurance''', which is the term used by the [[ITU]] and [[ATM Forum]].

Reliable protocols typically incur more overhead than unreliable protocols, and as a result, function more slowly and with less scalability. This often is not an issue for [[unicast]] protocols, but it may become a problem for [[reliable multicast]] protocols.
