+ #####Packet Throughput
+ There is a difference between an Ethernet frame, an IP packet, and a UDP datagram. In the seven-layer OSI model of computer networking, packet refers to a data unit at layer 3 (network layer). The correct term for a data unit at layer 2 (data link layer) is a frame, and at layer 4 (transport layer) is a segment or datagram.
+
+ Important concepts related to 10GbE performance are frame rate and throughput. The MAC bit rate of 10GbE, defined in the IEEE standard 802 .3ae, is 10 billion bits per second. Frame rate is based on the bit rate and frame format definitions. Throughput, defined in IETF RFC 1242, is the highest rate at which the system under test can forward the offered load, without loss.
+
+ The frame rate for 10GbE is determined by a formula that divides the 10 billion bits per second by the preamble + frame length + inter-frame gap.
+
+ The maximum frame rate is calculated using the minimum values of the following parameters, as described in the IEEE 802 .3ae standard:
+
+ - Preamble: 8 bytes * 8 = 64 bits
+ - Frame Length: 64 bytes (minimum) * 8 = 512 bits
+ - Inter-frame Gap: 12 bytes (minimum) * 8 = 96 bits
+
+ Therefore, Maximum Frame Rate (64B Frames)
+
+ = MAC Transmit Bit Rate / (Preamble + Frame Length + Inter-frame Gap)
