Abstract:
(EN) Provided in the embodiment of the present invention are a method, a device and a system for bandwidth allocation, so as to at least reduce uplink delay of a service based on TCP transmission in a DOCSIS network. The method comprises: a cable modem termination system CMTS determining, according to a rate at which a transmission control protocol TCP data packet is sent to a cable modem CM, a time T2 at which the CMTS receives a TCP acknowledgment ACK sent by the CM; and then, with a bandwidth corresponding to the time T2 as an initial bandwidth reference point, the CMTS allocating an uplink bandwidth for sending a TCP ACK data packet to the CM. The present invention is applicable to the field of communications.
(FR) Les modes de réalisation de la présente invention concernent un procédé, un dispositif et un système d'attribution de bande passante permettant au moins de réduire le retard de liaison montante d'un service sur la base d'une transmission TCP dans un réseau DOCSIS. Le procédé comprend les étapes suivantes : un système de terminaison de modem câblé (CMTS) détermine, en fonction du débit auquel un paquet de données de protocole TCP est envoyé à un modem câblé (CM), l'instant T2 auquel le CMTS reçoit un accusé de réception (ACK) de TCP envoyé par le CM ; puis, à l'aide d'une bande passante correspondant à l'instant T2 en tant que point de référence initial de bande passante, le CMTS attribue une bande passante de liaison montante pour l'envoi d'un paquet de données ACK de TCP au CM. La présente invention est applicable au domaine des télécommunications.
(ZH) 本发明实施例提供带宽分配方法、装置及系统,以至少降低DOCSIS网络中基于TCP传输的业务的上行时延。方法包括:电缆调制解调器终端系统CMTS根据向电缆调制解调器CM发送传输控制协议TCP数据包的速率确定该CMTS接收该CM发送的TCP确认ACK的时刻T2;进而,以所述时刻T2对应的带宽为初始带宽参考点,给该CM分配发送TCP ACK数据包的上行带宽。本发明适用于通信领域。
