TinyTP - Tiny Transport Protocol

Physical Layer

IrLAP

IrLMP

TinyTP

IrCOMM

IrLAN

IrOBEX

• Purpose:

  • Segmentation and Re-assembly
    • Automatically break-up large packets(and put back together correctly)
  • Per-channel Flow Control
    • Uses a “credit”-based system(credits allow sender to send)
    • Is necessary in order to avoid problems where 2 IrLMP connections are on same IrLAP connection
    • To avoid deadlock, credit-only packets are not subject to flow-control

• Note: TinyTP is technically an optional protocol stack level, but IrDA strongly recommends it in all IrDA implementations
