With the server object to be passed into ping test, it's not necessary
to either hardcode an IP address or provide a template. Instead, always
fill the IP address, which simplies the Ping() code.
Verify that we don't have an IP address/hardcoded by throwing an
assertion.
This is not really used as of now, because most IPs are hardcoded. See
one of the next commits for the use of this.
To make sure that we have the correct IP, there is some code that
verifies that a hardcoded IP and the CN IP would be the same.
Note: need two separate ci_infra.yaml entries, because
- for FlexRIC, the container name is different (is the tutorial CN)
- for RFsim5G E1, we don't have ext-dn => ping UPF
- call scripts for magma MME-based deployment of OAI 5GC in
ci_infra.yaml
- implement the existing python code through scripts (which does the same)
- save the cql file in the repo, which was previously downloaded every
time
- use for porcepix-cn4g and nano-cn4g (un)deployment, ping, perf, in XML
files
- Use scripts to deploy OpenShift-based 5GC in ci_infra.yaml
- Use for oc-cn5g, oc-cn5g-20897, and oc-cn5g-20897-aerial2
for (un)deployment, ping, iperf in relevant XML files
- Convert hardcoded IP addresses to %cn_ip%
Use the core network class to configure one "end" of these tests. This
will make the tests more generic and predictable, as they are explicitly
configured through two ci_infra.yaml "entities", instead of some
implicit "EPC" IP address given in configuration.
As of this commit, no XML passes this info into the framework, so no XML
step will work. As it is many changes, the following commits will add
the necessary info one by one.
This adds a helper class to manage various core networks in the CI
testing framework. Specifically, it reads from a YAML file information
such as a node, (un-)deployment script (file), log collection
instructions, etc., in order to allow a common interface to be used to
deploy and undeploy various core network implementations.
This commit adds the class (in cls_corenetwork.py) as well as tests for
this class.
These two functions use the EPC class to potentially fill in
EPC/5GC-related information, or start a packet tracer (tshark). The only
pipeline that uses these functions is RAN-gNB-N300-Timing-Phytest-LDPC,
which does not use a core network. This functionality is not used, and
can therefore be removed.
Add a possibility to use an "infrastructure YAML file" to configure both
ends of the iperf2 call through a file.
Fix bugs in Iperf2: at least on my machine, iperf2 start time is logged
at 0.00 not 0.0, so update the regex to match both. Do not overwrite
results if the matched regex (otherwise, the result might be None at the
end) and suppress server output.
Add a unit test to test that this function actually works (on my
machine, with iperf v2.2.1), as well as a unit test for analysis.
Added 3 way F1 handover test with data exchange in the F1 pipeline.
The major change is that the UE is acting as a server in the handover
scenarion, so it needs to comply with the changes in !3280.
Update of gNB-N300-Timing-Phytest threshold
Current results are in some cases well below the current thresholds. We should
periodically adapt them to actual values so that the test is meaningful.
fix(nrLDPC_coding): timers in DL encoding, fix(ldpctest): Confusion in sizes
Main improvements:
1. fix(ldpctest): Confusion in sizes
IMPORTANT: This fix makes that ldpctest now works with BG2 and K' != K!
(Worth double checking with more cases than I did check with though)
The variable block_length had an ambiguous role and was used as both K and
Kprime. This was leading to arrays with wrong sizes and functions with wrong
arguments. Now there is not anymore block_length but K and Kprime.
Kprime can be set with the command line argument -l.
There was also some problems with array allocation for segments with length
not divisible by 8. A proper sizing with ((size_in_bits + 7) & ~7) / 8 was
used.
A proper masking of the last byte containing payload bits was also added to
keep filler bits to 0 after random initialization.
2. fix(nrLDPC_coding): timers in DL encoding
While timers were available for rate matching and interleaving in the new
interface, these timers were not merged to rate matching and interleaving
timers in nr_dlsch_coding.
fix NTN LEO scenarios
- gNB: add support for NTN parameter ta-CommonDrift-r17
- NR UE: fix application of NTN TA information
- NR UE: add command line parameter ntn-initial-time-drift to compensate
time drift during initial sync
- NR UE: fix writeTimestamp inconsistencies
- NR UE: add MAC state UE_RECEIVING_SIB ensuring to start RA only after
successfully receiving SIBs
- rfsimulator: update earth radius for LEO simulation to match UE
position in ue.conf file
- update conf files for NTN LEO scenario
- update description how to run NTN scenarios in RUNMODEM.md
- fix: ta-Common is a round-trip-time, not a one-way delay
- NR UE: simplify calculation of next_tx_slot_and_frame by moving up
assignment of duration_rx_to_tx
- cellbarredNTN indicates notbarred in SIB1 if NTN access is available
- Removed b66 NTN and enabled B254 NTN conf file in CI
- NR UE: RRC layer now explicitly tells MAC layer when the RA procedure
can be started
- move NTN LEO config to band 254 and update doc/RUNMODEM.md
Closes#901
