A packet is a block of data with length that can vary between successive packets, ranging from 7 to 65,542 bytes, including the packet header.
- Packetized data are transmitted via frames, which are fixed-length data blocks. The size of a frame, including frame header and control information, can range up to 2048 bytes.
- Packet sizes are fixed during the development phase.
Because packet lengths are variable but frame lengths are fixed,packet boundaries usually do not coincide with frame boundaries.
