This extends the functionality provided by record in that it allows
collection of data into a Clickhouse database, allowing aggregation of
data from gNB and UE for functions like channel estimation for PUSCH
transmissions that did not decode successfully at the gNB.
It is intended to be used in conjunction with Aerial Data Lake but is
not limited to it. Data access is simpler than in !3462, but could be
improved using the metadata approach from !3462.
The integration uses logfmt for fast logging, and a clickhouse DB
client, both integrated using CPM.
This change set also adds a docker-compose file for a UE on 100MHz, to
be used with Aerial configurations, and builds the tracer for Aerial and
nrUE docker files.
Add Ethernet PDU session support and make PDU session request configurable
This MR adds support for Ethernet PDU sessions, and makes PDU sessions
configurable: per-PDU session ID, type (IPv4/IPv4v6/IPv6/Ethernet [1]),
DNN, NSSAI.
Concretely, it adds a new configuration file section pdu_sessions below
uicc0 that looks like this if everything is specified (default values
are shown):
uicc0:
[...]
pdu_sessions:
- id: 1
type: "IPv4"
nssai_sst: 1
nssai_sd: 0xffffff
dnn: "oai"
It is possible to list multiple PDU sessions (add new line - id: 2 to
request a second PDU session). It is backwards-compatible to the current
PDU session configuration (uicc0.dnn/nssai_sst/etc), the idea being that
either legacy or new configuration could be used, but (1) if
pdu_sessions exist, it will overwrite the legacy configuration, and (2)
multiple PDU sessions, and type, can only be configured using the new
config. The old parameters --extra-pdu-id and --default-pdu-id are not
accepted anymore. Documentation has been added to the UE tutorial.
It is possible to test an Ethernet PDU session [1]. It is possible to
test the PDU session inside the UE by verifying it has an TAP interface
oaitap_ue1, and ARPing the data network (arping has been added to
oai-nr-ue container for that purpose):
ip addr add 192.168.72.140/26 dev oaitap_ue1 # same subnet as data network!
ip link set dev oaitap_ue1 up
arping -c 20 -I oaitap_ue1 192.168.72.135 # will send ARP request in Ethernet frame to get IP address of data network
[1] See description MR !3769 for more information. On the UE side, only
the type has to be changed to "Ethernet".
The CN team would like to test the ethernet PDU session capabilities of
the UPF. Install arping in the UE by default for ubuntu to help them
test the PDU session by pinging over ARP.
Improve MAC docs for MCS and docker for BuildKit usage
See commits for details. The first one is for fixing an omission in
!3281, the second to clarify docker build usage.
Closes: #973
