  • Method, system and program product for equitable sharing of a CAM table in a network switch in an on-demand environment
    Patent number: 7711900
    Abstract: A method, system and program product for equitable sharing of a CAM (Content Addressable Memory) table among multiple users of a switch. The method includes reserving buffers in the table to be shared, the remaining buffers being allocated to each user. The method further includes establishing whether or not an address contained in a packet from a user is listed in a buffer in the table, if the address is listed, updating a time-to-live value for the buffer for forwarding the packet and, if the address is not listed, determining whether or not the user has exceeded its allocated buffers and whether or not the reserved buffers have been exhausted, such that, if the user has exceeded its allocated buffers and the reserved buffers have been exhausted, the address is not added to the table and the user is precluded from using any additional buffers in the network switch.
