**Best-effort Delivery** describes a network service in which the network does not provide any guarantee that data is delivered or that delivery meets any quality of service. In a best-effort network, all users obtain best-effort service, meaning that they obtain unspecified variable bit rate and [[ddsf:public:guidebook:06_append:glossary:l:latency|latency]] and [[ddsf:public:guidebook:06_append:glossary:p:packetloss|packet loss]], depending on the current traffic load. This can be contrasted with reliable delivery, which can be built on top of best-effort delivery (possibly without latency and [[ddsf:public:guidebook:06_append:glossary:t:thruput|throughput]] guarantees), or with circuit switching schemes which maintain a defined, continuous quality of service.
