Abstract
The method can be implemented on a processor executing software instructions stored in memory. In one embodiment of the invention, the method includes receiving an Ethernet frame, wherein the Ethernet frame comprises an IP datagram, wherein the IP datagram comprises an IP header and an IP payload, wherein the IP payload comprises a User Datagram Protocol (UDP) header. When the Ethernet frame is received, a length in bytes of the IP payload of the IP datagram is calculated.
