distributed reservation protocol (DRP)

The Distributed Reservation Protocol (DRP) is used in WLANs according to 802.11e and supports the controlled reservation of transmission slots by several stations.

In order for the individual stations to recognize which transmission slots are reserved for media access, corresponding messages are available for the participating stations via the Distributed Reservation Protocol. Thus, the individual stations know which Medium Access Slots (MAS) are occupied and which are available.

The implementation of the Distributed Reservation Protocol must take into account the application-specific requirements for low latency or high data throughput. If too many consecutive medium access slots are occupied by an application, this is reflected in the reduction in latency.
