Timeline

• 24 June - Implement the UDP/IPv4 modules based on the new TX and RX datapath. The sub-tasks involved here are:
  1. Define a gPXE UDP API similar to the the gPXE TCP API
  2. Define a UDP connection
  3. Implement the API functions (working on it)
  4. Define the interface between the transport and network layers (working on it)
  5. Implement IPv4 functions: reassembly, rx_process, transmit, etc.
  6. Write a tester function
  7. Debug and test!

Milestone: we should be able to send a "hello, world" message over
UDP/IPv4/Ethernet to a listening connection and receive some response.

• 10 July - Build TCP support into gPXE. The sub-tasks¹⁾ involved here are:
  1. Revise the transport-network layer interface
  2. Implement the TCP state machine

Milestone: we should be able to build gPXE with TCP support over IPv4

• 20 July - Investigate IPv6 support. Discuss the implementation. Sub-tasks are:
  1. Read the relevant RFCs and understand IPv6 requirement thoroughly
  2. Make mofidications to the network interfaces if necessary
  3. Discuss the implementation on E-D

• 30 July - Implement essential IPv6 support

Milestone: we should be able to build UDP and TCP over IPv6 and test is sucessfully

• Buffer and wrap-up period. Clean the code. Debug and document it.
