In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. [1]: 25 The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g., Ethernet frame.
In computer networking, RWIN (TCP Receive Window) is the amount of data that a computer can accept without acknowledging the sender. If the sender has not received acknowledgement for the first packet it sent, it will stop and wait and if this wait exceeds a certain limit, it may even retransmit .
1. Check to see if the destination is an address ‘owned’ by this computer. If so, process the packet. If not: a. Check to see if IP Forwarding is set to ‘Yes’. If no, the packet is destroyed. If yes, then i. Check to see if a network attached to this computer owns the destination address. If yes, route the packet to the appropriate network.
The relative scalability of network data throughput as a function of packet transfer rates is related in a complex manner to payload size per packet. [17] Theoretically, as line bit rate increases, the packet payload size should increase in direct proportion to maintain equivalent timing parameters.
WAN optimization is a collection of techniques for improving data transfer across wide area networks (WANs). In 2008, the WAN optimization market was estimated to be $1 billion, [1] and was to grow to $4.4 billion by 2014 according to Gartner, [2] a technology research firm.
If the data in a single write spans 2n packets, where there are 2n-1 full-sized TCP segments followed by a partial TCP segment, the original Nagle algorithm would withhold the last packet, waiting for either more data to send (to fill the packet), or the ACK for the previous packet (indicating that all the previous packets have left the network).

Ethernet is a "local area network" (LAN) technology, which is also framed. The way the frame is electrically defined on a connection between two systems is different from the typically wide-area networking technology that uses HDLC or PPP implemented, but these details are not important for throughput calculations.
