DQLAN - A DQRAP Based LAN Protocol
نویسندگان
چکیده
1 Abstract1 DQRAP approaches the performance of an idealized M/D/1 queueing system. It provides the theoretical basis for developing practical protocols that can operate in diverse multiaccess channel environments such as LANs, MANs, WANs and satellite networks. In this paper we present DQLAN, a DQRAP based protocol that supports variable length frames in a high-speed LAN environment. The DQLAN protocol is described and simulation results for 10, 100 Mbps, and 1 Gbps versions are presented. The simulation results at 10 Mbps are compared with CSMA/ CD.

Shared versus Switched or Reports of the Death of Shared Access are Greatly
Indications are that a shared environment supported by DQSA (Distributed Queue Switch Architecture) is superior to the conventional switch/router environment for most communications. DQSA and its constituent MACs (DQRAP, XDQRAP, DQLAN, PDQRAP, and CDQ), developed at the Illinois Institute of Technology, represent a major development in shared access communications. A DQSA-based MAC (medium acce...
متن کاملDQRAP with Announced Arrival for a Broadcast Channel1
The DQRAP (Distributed Queueing Random Access Protocol) protocol is a random multiple access protocol for a slotted broadcast channel shared by an infinite number of bursty stations, which can achieve a performance approaching that of a hypothetical perfect scheduling protocol (i.e. an M/D/1 system). In this paper two variations of the DQRAP protocol, DQRAP with announced arrival (DQRAP/AA) and...
متن کاملCBR Channels on a DQRAP-based HFC Network
DQRAP (Distributed Queueing Random Access Protocol), is a multiple access protocol that offers a throughput equal to the offered traffic up to a load of one with a lesser delay than any other multiple access protocol. DQRAP utilizes three control minislots and two distributed queues: transmission and collision resolution, to provide this performance for all values of "a", i.e., the size of the ...
متن کاملUsing DQRAP (Distributed Queueing Random Access Protocol) for Local Wireless Communications
Establishing voice circuits by transmitting voice packets, i.e., transmitting only when there is sound, has been studied for some 30 years. Despite the theoretical efficiency few such systems have been implemented, possibly because of the inadequacy of available multiple access protocols. A new protocol, DQRAP (Distributed Queueing Random Access Protocol), developed by Xu and Campbell at the Il...
متن کاملPerformance Analysis of Distributed Queueing Random Access Protocol - - DQRAP
Distributed Queueing Random Access Protocol (DQRAP) is a multi-access protocol for a broadcast channel that provides performance superior to any other protocol with respect to stability, delay, and throughput. DQRAP achieves this performance with a transmission queue TQ, a collision resolution queue RQ, and ternary feedback from as few as three minislots. Xu and Campbell introduced DQRAP and pr...
