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 telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network. A packet consists of control information and user data; [ 1 ] the latter is also known as the payload .
A media access control protocol data unit (MAC PDU or MPDU) is a message that is exchanged between media access control (MAC) entities in a communication system based on the layered OSI model. [2] In systems where the MPDU may be larger than the MAC service data unit (MSDU), the MPDU may include multiple MSDUs as a result of packet aggregation.
Packet switching allows delivery of variable bit rate data streams, realized as sequences of short messages in fixed format, i.e. packets, over a computer network which allocates transmission resources as needed using statistical multiplexing or dynamic bandwidth allocation techniques.
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.
Generally deployed Internet Protocol (IP) traffic classification techniques are based approximately on a direct inspection of each packet’s contents at some point on the network. Source address, port and destination address are included in successive IP packets with similar if not the same 5-tuple of protocol type. ort are considered to ...

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.
