DMACS: A Media Access Protocol for Single-Hop WDM.. - Michael Montgomery And (Correct)
....because a station does not have to tell the destination it is transmitting. Fixed access protocols are stable but do not accomodate bursty traffic efficiently. Random access protocols handle bursty traffic well but have limited throughput due to collisions. Dynamic Interleaved Slotted Aloha (DISA) [6] is a hybrid protocol which uses a local flow control threshold based on the number of collisions plus arrivals per cycle to locally switch between random access and fixed access modes of operation. Each station is equipped with a TT and a FR. If each FR is at a unique wavelength, a station has a ....
....cycle and slot synchronization is assumed. Synchronization in DMACS is required on data packet boundaries instead of control packet boundaries making timing requirements less stringent. 2. 2 Definitions Relevant definitions for DMACS, including those from the DISA protocol description [6], are given below. ffl TDMA destination: For a given slot, this is the TDMA allocated destination channel for the given source station [6] ffl circuit destination: For a given slot, the circuit destination channel, if it exists, supersedes the TDMA destination. ffl random destinations: These ....

DISA [52] is a hybrid protocol which functions as a random protocol at low loads and a xed protocol (TDMA) at high loads. DISA uses a local ow control threshold based on the number of collisions plus arrivals in the past cycle to switch between the random access and xed modes of operation. DMACS [53] is ....
