Title: Apparatus and method for monitoring data flow at a node on a network
Inventor: CARLSON JAMES D
IPC: H04L12/56
Filed: 2000-01-28
Abstract: An apparatus and method for monitoring data flow at a node on a network are disclosed. A memory location or "bucket" is allocated to each of a plurality of links and classes of service at the node. A free-running counter is incremented at a rate determined by the maximum allowable data rates on the various links and classes of service. When a data packet is received at a particular link and class of service, the corresponding memory location or bucket is adjusted or "leaked" by subtracting the present counter value from the present bucket contents. That difference is then added to the number of units of data, i.e., bytes or groups of bytes of data, contained in the incoming packet. That sum is then compared with a predetermined threshold determined by the allowable data rate associated with the link and class of service. If the threshold is exceeded, then the incoming data packet is marked accordingly. The system can include multiple stages of monitoring such that multiple thresholds can be used to assign one of the multiple discard eligibility values to the incoming packet.

Patent CA-2328127-A1 (CA)
Title: System and method for facilitating inter-nodal protocol agreement in a telecommunications system
Inventor: REICHELT MARTIN
IPC: H04L29/06
Filed: 1999-04-07
Abstract: A system and method in a communications network for minimizing the number of attempts required to establish a communication between two nodes is disclosed. Each node maintains a database table composed of addresses of other nodes within the communications system. Associated with each nodal entry is a list of dialogue types that have been initiated with or terminated from the relevant node. Associated with each dialogue type entry is the most-advanced protocol version, such as the Mobile Application Part (MAP), that has been negotiated with the affiliated node for that dialogue type. When a first node wishes to initiate a dialogue with a second node, the first node checks the database table. The first node locates the second node in the table by address, locates the appropriate dialogue by type, and then determines the appropriate MAP version. If either the node or the specifically desired dialogue type is not within the database table, the first node attempts to establish the dialogue with the highest MAP version that the first node supports. After any resulting fall-back procedure has occurred, the first node stores in the database table the highest MAP version that was negotiated. The database table is periodically refreshed by clearing one or more entries.

IPC: G06F17/10
Filed: 1999-09-24
Abstract: L'invention concerne l'augmentation d'un algorithme de convolution rapide modifié dans le but d'accroître sa flexibilité. Dans un mode de réalisation, on introduit une unité de repliement en tant qu'étape de prétraitement dans l'IDFT du récepteur. Cette unité de repliement ajoute des composantes de fréquence extérieures aux composantes de fréquence intérieures du domaine de fréquences, de manière à produire un ensemble réduit de composantes de fréquence. Dans un autre mode de réalisation, on introduit une unité de dépliement en tant qu'étape de post-traitement après le DFT de l'émetteur. Cette unité de dépliement grossit l'ensemble de composantes de fréquence par apport de composantes originales traduites à l'extérieur de l'ensemble original. Ces processus de repliement et de dépliement augmentent la flexibilité de l'algorithme de convolution rapide modifié, étant donné qu'ils limitent le nombre d'opérations à la seconde devant être exécutées pour les parties de l'algorithme spécifiques à la voie. Ceci permet également de traiter davantage de voies au moyen d'une seule puce, à cause de la diminution du nombre d'opérations par voie.
