UTILIZATION OF CONNECTION ADMISSION CONTROL CHECK ON PHYSICAL INTERFACE CONNECTIONS BEARING TRAFFIC FROM MULTIPLE INTERNET SERVICE PROVIDERS

摘要

A cable modem termination system (200) that uses a connection admission control process to monitor a physical interface connection to the Internet for bandwidth usage. Internet service providers (301 and 302) are coupled to the cable mode termination system's physical interface port (201) through the Internet. Each of the Internet service providers are assigned a predetermined bandwidth based on the quantity of subscribers assigned to each Internet service provider. If the connection admission control process determines that an Internet service provider is over using the assigned bandwidth, that Internet service provider is given a message indicating this over usage. The connection admission control process is also used to monitor the bandwidth usage of cable modem channels and physical interface or other types of physical interface channels.
