    • Buffer: Unit of contiguous memory, allocated by software. • Frame: Buffer(s) that hold a data element (generally a packet) − Frames can be single buffers or multiple buffers (scatter/gather lists)  A “simple frame” has one delimited data element  A “multi buffer frame” has two or more data elements. − A “Compound frame” consists of multiple related delineated units • Frame Descriptor (FD): Proxy structure used to represent frames. • Frame Queue: − FIFO of related Frames Descriptor.(e.g. TCP session) − The basic queuing structure supported by QMan • Frame Queue Descriptor (FQD): Structure used to manage Frame Queues FD FD FD FD … Buffer Buffer Buffer Buffer FQD FD FD Ethernet Frame Pre- amble Dest addr Src addr Type Data CRC TM 4 Freescale, the Freescale logo, AltiVec, C-5, CodeTEST, CodeWarrior, ColdFire, C-Ware, the Energy Efficient Solutions logo, mobileGT, PowerQUICC, QorIQ, StarCore and Symphony are trademarks of Freescale Semiconductor, Inc., Reg.
