Problems solved by technology

[0008] The current method also has a big defect, that is, even if the CM is already in the offline state, it must reach the aging time before it is allowed to release resources, and within the aging time, the CM that is already in the offline state cannot be deleted, so if the CMTS If the online CMs are all within the aging time, the newly launched CMs still cannot go online normally.

Embodiment 1

[0043] This embodiment provides a resource allocation method in the DOCSIS system. In this method, a CM information table on the CMTS is required, and the CM information table stores serial numbers and priorities of CMs registered on the CMTS. There can be one CM information table, then there are multiple entries in this CM information table, and each entry stores the serial number and priority of the CM registered on the CMTS; there can also be multiple CM information tables, each The CM can store the serial number and priority of a CM registered with the CMTS.

[0044]The CM information table may also store the MAC address of the registered CM, which is used to indicate the serial number assigned by the CM corresponding to the MAC address.

[0045] In another embodiment of the present invention, the priority may also be represented by the sum of the bandwidths of all service channels on the CM, and the greater the sum of the bandwidths, the higher the priority. This embodim...

Embodiment 2

[0084] This embodiment provides a method for resource allocation in a DOCSIS system. In the method provided by this embodiment, a CM information table needs to be stored on the CMTS, and the CM information table stores the serial numbers and priorities of CMs registered on the CMTS. class.

[0085] The CMTS also needs to save the corresponding relationship between parameters and priorities. This corresponding relationship can be issued by the network management device, or can be directly configured on the CMTS. The parameters may be one or more of an uplink channel identifier, a downlink channel identifier, an IP address, and a MAC address of the newly online CM.

[0086]For the IP address, the CMTS will monitor the DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) dialing process of the CM or the CPE connected under the CM. After the DHCP server assigns an IP address to the CM or CPE, the CMTS will record the assigned IP address. Because the op...

Abstract

Disclosed is a resource allocation method. A CM information table is provided in a CMTS, and serial numbers and priorities of CMs registered on the CMTS are stored in a table entry of the CM information table. The method comprises: receiving, by a CMTS, a registration message from a new on-line CM, and when the number of serial numbers of CMs stored in a CM information table reaches a set number, allocating a temporary serial number which is greater than the set number to the new on-line CM; acquiring, by the CMTS, a configuration file of the new on-line CM, and acquiring a priority of the new on-line CM from the configuration file; and acquiring a table entry with a priority lower than that of the new on-line CM from the CM information table, and allocating the serial number in the acquired table entry to the new on-line CM.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource allocation method, device and system. Background technique [0002] figure 1 It is a network architecture diagram of an existing DOCSIS (Data-Over-Cable Service Interface Specifications, data-over-cable service interface specification) system. exist figure 1 Among them, CMTS (Cable Modem Termination System, Cable Modem Termination System) passes EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), GPON (Gigabit-Capable Passive Optical Network, Gigabit Passive Optical Network) in the upstream direction Or GE (Gigabit Ethernet, Gigabit Ethernet) is connected to OLT (Optical Line Terminal, Optical Line Terminal). In the upstream direction, the OLT is connected to an IP (Internet Protocol, Internet Protocol) network through a router or a layer-3 switch. The CMTS mixes the data signal and video signal from the OLT in the downli...
