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： In a packet processing apparatus and method in an ethernet switching system, an introduced packet is discarded by switching to a dummy port instead of trapping the packet until a layer 3 table of an ethernet switch chip is updated, thereby operating an Address Resolution Protocol (ARP) after having minimized a central processing unit (CPU) load. The packet processing apparatus, upon receipt of a first packet headed for a destination Internet protocol (IP) address not existing in the packet processing unit from a source host, transmits an ARP request packet to the destination IP address so as to acquire routing information of a destination host. When the packet processing apparatus receives a second packet headed for the IP address of the destination host from the source host before an ARP response packet is received in accordance with the ARP request packet and before the routing information corresponding to the IP address of the destination host is acquired, it switches the packet based on imaginary routing information.

摘要： Disclosed is a packet switch apparatus applied to Internet Protocol (IP) network, the packet switch apparatus including: an Ethernet switch to perform packet switching, the Ethernet switch including a plurality of ports and a layer 3 table. The plurality of ports include a dummy port, which has an available port number allowing hardware-access, discards packets switched to the dummy port, and exists as a logical number, the layer 3 table storing Media Access Control (MAC) addresses corresponding to IP addresses of hosts and information about corresponding connection ports. A controller determines the nonexistence of the MAC address, virtually sets the MAC address corresponding to the destination IPv6 address, and updates the layer 3 table of the Ethernet switch chip as if the host of the set virtual MAC address were connected to the dummy port, when the MAC address corresponding to destination IPv6 address of the packet trapped by the Ethernet switch chip does not exist.
