This release includes the following changes:
Fix an issue that was causing UE traffic to be dropped after restarting PFCP-Agent
Allow configuration of slice rate limits via PFCP-Agent REST APIs
Clean up app filter IDs when they are no longer used
Support canonical representation of byte-strings for outgoing P4Runtime messages
Support for in-order operations in the FlowRuleService
Support for slice rate limits in P4-UPF comes with the following limitations that will be removed in SD-Fabric 1.2:
We only support setting the same rate for downlink and uplink. When different rates are provided using PFCP-Agent REST APIs, we pick the highest between downlink and uplink.
When using topologies with paired-leaves, if UE traffic is forwarded through the pair link, the slice rate limit will be enforced on the aggregate of uplink and downlink traffic. This can happen when the base station and/or the edge server/upstream router are not dual-homed. If all endpoints are dual-homed, then UE traffic if expected to use the pair link only in case of failures.
