Title (EN) CONSTANT BIT RATE TRANSPORT IN A CONTENTION BASED MEDIUM ACCESS CONTROL
(FR) TRANSPORT A DEBIT BINAIRE CONSTANT DANS UN CONTROLE D'ACCES AU SUPPORT EN MODE CONFLIT D'ACCES
Abstract:
(EN) In a two way cable system that includes a controller and a plurality of user terminals (Fig. 1), a method of granting rights for upstream data transmission from the user terminals includes processing contention requests to generate contention grants and maintaining a list of connections, each connection having specified therefor a predetermined bit rate. The controller sends a downstream data stream to the user terminals and receives an upstream data stream from the user terminals. The downstream data stream includes a plurality of grant fields, and the upstream data stream includes upstream data slots and upstream control slots.
(FR) Dans un réseau câblé bidirectionnel comprenant un contrôleur et une pluralité de terminaux utilisateurs (Fig. 1), un procédé visant à accorder des droits concernant l'émission de données montantes depuis les terminaux utilisateurs, consiste à traiter des demandes conflits d'accés afin de générer des autorisations d'accès en conflits d'accès et tenir à jour une liste de connexions, un débit binaire prédéterminé étant spécifié pour chaque connexion. Le contrôleur envoie un flux de données descendantes aux terminaux utilisateurs et reçoit un flux de données montantes provenant de ces terminaux. Le flux de données descendant comprend une pluralité de zones autorisations d'accès, et le flux de données remontant comprend des tranches destinées aux données montantes et des tranches destinées au contrôle montant de gestion.
