摘要： A system and methods for automatic digital certificate installation on network devices in a data-over-cable network are developed. One of the methods includes sending a digital certificate request from a cable modem to a predetermined network server upon determining on the cable modem that there is no digital certificate already installed on the cable modem. The method further includes generating at least one digital certificate on the network server and providing the at least one digital certificate to the cable modem.

摘要： A system and methods for traffic gating in a computer network comprising a plurality of subnets are developed. One of the methods implemented in a data-over-cable system includes, responsive to receiving a first address resolution request message on a cable modem from a first host to a second host, generating a second address resolution request message on the cable modem and sending it to the second host. If the second host does not respond with an address resolution protocol reply message to the second request message, the cable modem determines a network subnet associated with the first host. Based on the network subnet, the cable modem determines a network address of a network element arranged to provide routing services to hosts on the subnet associated with the first host. Next, the cable modem generates an address resolution reply message including the network address of the network element and sends it to the first host.

摘要： A system and method for proxying Dynamic Host Configuration Protocol (“DHCP”) network services for a network device, such as, a customer premise equipment entity, on a network device, such as, a cable modem, include creating a specialized proxy task for the customer premise equipment entity on the cable modem. One method of the present invention includes intercepting DHCP message flow between a customer premise equipment having a specialized proxy task created on the cable modem and a DHCP server selected by the customer premise equipment entity. The methods further include modifying lease time intervals prior to providing a routable network address lease to a customer premise equipment entity and renewing an initial lease for the customer premise equipment entity by a cable modem prior to expiration of the lease time interval provided by a DHCP server. The methods include using known protocols, such as, for example, the Dynamic Host Configuration Protocol.
