O-DU High

This page describes running O-DU High using test stubs, namely CU Stub and RIC Stub. O-DU High also uses Phy Stub in the absence of O-DU Low. However, Phy Stub is built as a part of the O-DU High image itself.

Execution of below steps yields successful UE Attach procedure and message exchanges required for Traffic Steering use-case on the E2 interface. These can be verified on wireshark by capturing SCTP packets.

1. Cloning code

   mkdir odu_high
   cd odu_high
   git clone "https://gerrit.o-ran-sc.org/r/o-du/l2"

2. Compilation of O-DU

   cd odu_high/l2/build/odu
   make clean_odu odu MACHINE=BIT64 MODE=FDD

3. Compilation of CU Stub

   cd odu_high/l2/build/odu
   make clean_cu cu_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

4. Compilation of RIC Stub

   cd odu_high/l2/build/odu
   make clean_ric ric_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

5. Execution - Assign IP addresses

   ifconfig <interface name>:ODU “192.168.130.81”
   ifconfig <interface name>:CU_STUB “192.168.130.82”
   ifconfig <interface name>:RIC_STUB “192.168.130.80”

6. Running CU Stub

   cd odu_high/l2/bin/cu_stub
   ./cu_stub

7. Running RIC Stub

   cd odu_high/l2/bin/ric_stub
   ./ric_stub

8. Running O-DU

   cd odu_high/l2/bin/odu
   ./odu

   Note:

   1. Each of the above binaries must be run in separate terminals

   2. CU Stub and RIC Stub images must be run before O-DU image.
