Abstract
Method for processing content of an Internet Protocol (IP) packet and method for processing a full broadcast IP packet. Processing content of an IP packet includes: extracting IP source and destination addresses and payload from the IP packet; and generating an IP frame encapsulating the IP source and destination addresses and the payload between a preamble field and an error checking field. Processing a full broadcast IP packet includes: receiving the full broadcast IP packet including an IP source address and a full broadcast IP destination address; ascertaining a closest matching IP address and a subnet thereof in a switching table of an IP switch; replacing the full broadcast IP destination address in the IP packet with a subnetted source address generated by applying the subnet mask to the IP source address; transmitting the IP packet to all IP addresses in the switching table within the subnetted source address.
