Filed:

Aug 31, 2001

Appl. No.:

09/945298

Inventors:

Kartik Chandran - Mountain View CA, US
Chrisanto Leano - San Jose CA, US
Sunil Khaunte - Santa Clara CA, US

Assignee:

International Classification:

H04L 12/28
H04L 12/56
H04J 3/12
H04N 7/173

US Classification:

3703955, 370522, 725111, 709228

Abstract:

A method of using DOCSIS 1. 1 features to allow the addition of ISPs and QOS levels to a single cable modem without having to modify the CMTS is described in the various figures. Instead of using the SID of a data packet to determine the VPN tag of a data packet (DOCSIS 1. 0), a service flow is used to identify the appropriate tag. This is done using the DOCSIS 1. 1 configuration file. By doing so, the need for creating additional sub-interfaces in the cable modem interface does not arise. Instead, the configuration is modified at the provisioning server, i. e. , the DHCP/TFTP server.
