Title (EN) CELL GRANT MECHANISM
(FR) MECANISME D'AUTORISATION DE TRANSMISSION DE CELLULES
Abstract:
(EN) A cell grant mechanism is presented which allows a central device (110) to control the transmission of cells from one or more remote devices (140) connected to the central device (110) over a physical medium. Grants are issued from a grant table (700) in the central device (110) to allow the remote devices (140) to transmit cells to the central device (110). The spacing of the grants are optimized to minimize cell delay variation. When there are unused cell opportunities, central device (110) can issue grants to devices (140) to utilize the unused cell opportunities on an available bit rate basis.
(FR) L'invention concerne un mécanisme d'autorisation de transmission de cellules. Ce mécanisme permet à un dispositif central (110) de commander la transmission des cellules à partir d'un ou plusieurs dispositifs à distance (140) connectés au dispositif central (110) sur un support physique. Les autorisations sont émises à partir d'une table d'autorisations (700) dans le dispositif central (110) pour permettre aux dispositifs à distance (140) de transmettre les cellules au dispositif central (110). Les intervalles entre les autorisations sont optimisés pour minimiser la variation des retards des cellules. En cas de possibilités de cellules non utilisées, le dispositif central (110) peut adresser des autorisations aux dispositifs (140) pour utiliser les opportunités de cellules non utilisées sur une base de débit binaire disponible.
