μip (micro ip) is a compact TCP/IP stack designed for memory-constrained embedded products, particularly 8- and 16-bit microcontrollers. It features minimal RAM and CPU usage, allowing for efficient network operation, and is integrated with the Contiki operating system. While it offers advantages such as high throughput and low resource requirements, it may initiate packet responses before the receiving device is ready.

3. Introduction
• µIP (micro IP) is very small TCP/IP stack.
• Open source, widely used memory-constrained embedded product.
• This protocol stack intended for use with tiny 8- and 16-bit microcontrollers.
• Developed by Adam Dunkels

7. Implementation
• Latest version of uIPv6, are integrated with Contiki.
• An open-source operating system for the Internet of Things
• Actually uIP stack is designed for small computer system with no operating system.

8. Operations
• Called in a timed loop.
• Then call manages other network behavior.
• uIP calls the hardware driver to sent the packet of data.
• uIP build the packet before.
• It used packet buffer in a half-duplex way for transmission and reception.
• If needs to retransmit, its just call the application code to sent previous data.

9. Connection Management
• Have one task per connection
• Task communicates with a task in a distant computer on the other end.
• Connections are held in an array.
• On each call, uIP tries to serve a connection.
• Making a subroutine call to responds to, or sends data

10. Advantage
• Throughput speed
• Minimum RAM usage
• Minimum CPU usage
• Work with tiny 8- and 16-bit microcontrollers
• The uIP stack uses less then 10kB ROM and 2kB RAM and Contiki can easily fit in 100kB.
ROM and 10kB RAM.

11. Weaknesses
uIP system can start a responding packet before the PC is ready to receive it.

12. Conclusion
• Micro IP (µIP) is widely used TCP / IP network protocol.
• Its used for its lightness.
• Its need low memory and processing speed.
• Some micro IP device can communicate faster then normal PC.
