摘要： Disclosed is a packet switch equipment and a band control method using same. In accordance with one embodiment of the invention, a number of packets are sampled by using a packet sampling function provided by a packet switch chip, and the sampled packets are transmitted to a CPU. By using the transmitted sample packets, the total amount of bandwidth used by a corresponding user is estimated based on the source MAC address or the source IP address. If the estimated value exceeds a predetermined threshold, a bandwidth limitation function is applied to the user that is providing packets that exceed the bandwidth. A number of users can be dynamically recognized even when they are undefined, and a dynamic bandwidth limitation function is performed by tracking the bandwidth used by a corresponding user.

摘要： A solution for allowing conditional access to IP-based broadcast services in a passive optical network is disclosed. When a subscriber requests broadcast services by selecting a broadcast channel, an IP set-top converts the request into an IGMP join message and forwards the message to an ONU/ONT, a unit on the subscriber's side. The ONU/ONT delivers the message to an OLT interworking with a router while storing mapping information of the port that received the message and a MAC address of the selected channel. Thereafter, the OLT extracts information on MAC address of the IP set-top box and the requested broadcast data. The OLT compares the extracted information to the subscriber's subscription information and determines whether to provide the requested broadcast services. If the broadcast services may be provided, the broadcast data provided from the broadcast server is transmitted to the IP set-top box via ONU/ONT based on the stored mapping information.
