Abstract
A system and method for operating a communication network having one or more cable modems. Operating the communication network may include displaying one or more messages to a subscriber and making temporary changes to Cable Modem Termination Systems in order to modify the availability of network resources for one or more cable modems assigned to a subscriber without requiring a rebooting of the one or more cable modems.
Claims18
A method of configuring a redirection of data traffic of a cable modem in a cable-operated network comprising an edge router connecting the cable-operated network to an internet, the method comprising:
- providing a captive portal application on a web server in the cable-operated network configured to provide a webpage;
- configuring a policy server in the cable-operated network to read a messaging policy;
- after receiving the message policy, configuring the policy server to instruct a Cable Modem Termination System (CMTS) in the cable-operated network to create a gate between the cable modem and the CMTS, the gate is configured to filter an IP packet for the cable modem included in the messaging policy, further comprising the steps of:
- receiving by the CMTS via the cable modem a request comprising the IP packet and a header of the IP packet from a computer connected to the cable modem;
- adding, by the CMTS, a tag in the header of the IP packet, wherein the IP packet input to the CMTS is unmodified;
- in response to the edge router implementing policy-policy based routing, redirecting by the edge router, the IP packet to the captive portal application based upon the tag in the header of the IP packet;
- in response to the edge router not implementing the policy-based routing, configuring, by a service provider, a virtual private network between to CMTS and the web server and redirecting, by the CMTS, the IP packet to the captive portal application based on the tag in the header of the IP packet;
- configuring the captive portal application to receive the request from the computer;
- retrieving a policy associated with a MAC address of the cable modem connected to the computer;
- and
- generating to the computer a response to the request, the response including the webpage having a message associated with the policy associated with the MAC address.
A system for redirection of data traffic of a cable modem in a cable-operated network comprising an edge router connecting the cable-operated network to an internet, the system having a specially-programed processor configured to perform:
- providing a captive portal application on a web server in the cable-operated network configured to provide a webpage;
- configuring a policy server in the cable-operated network to read a messaging policy;
- after receiving the message policy, configuring the policy server to instruct a Cable Modem Termination System (CMTS) in the cable-operated network to create a gate between the cable modem and the CMTS, the gate is configured to filter an IP packet for the cable modem included in the messaging policy, further comprising the steps of:
- receiving by the CMTS via the cable modem a request comprising the IP packet and a header of the IP packet from a computer connected to the cable modem, wherein the IP packet input to the CMTS is unmodified;
- adding, by the CMTS gate, a tag in the header of the IP packet;
- in response to the edge router implementing policy-policy based routing, redirecting by the edge router, the IP packet to the captive portal application based upon the tag in the header;
- in response to the edge router not implementing the policy-based routing, configuring by a service provider, a virtual private network between to CMTS and the web server, and redirecting by the CMTS, the IP packet to the captive portal application based on the tag in the header of the IP packet;
- configuring the captive portal application to receive the request from the computer;
- retrieving a policy associated with a MAC address of the cable modem connected to the computer;
- and
- generating to the computer a response to the request, the response including the webpage having a message associated with the policy associated with the MAC address.
