Dear,
We are having a parallel discussion about the mandatory use of the EPP element in (Re)Association Request frames. We need this to agree on the BPE and CPE operation in clause 10.71.2.2.
- it is true that in the (Re)Association Request frame definition, the EPP element is defined as optional.
- yesterday we agreed on having the EPP element sent (with a shall) in (Re)Association request frames due to the need of sending always the AID storage size in section 10.71.2.2. We need to make this coherent with the definition of the (Re)Association Request frame if we keep it like that.
- the EPP element includes the epoch duration as a mandatory field. When designing this element we decided to always send the most important information for an epoch, its duration. The non-AP declares a will to join a group with this duration, while the AP states the actual duration of the group it assigns the non-AP to.
Now, we have an issue with BPE. It looks like BPE aims at having the EPP element included in the (Re)Association Request frame, but only with the AID storage size (if I understood correctly).
I see four options to this, and we need to decide soon since we need to have the text ready asap:
1- We change the EPP Epoch Settings field to not have the Epoch duration as a mandatory field.
2- We declare the EPP element is optional in (Re)Association request frames for BPE and mandatory for CPE.
3- We do not have the EPP element mandatory in (Re)Association Request frames no matter the CPE or BPE.
4- BPE learns to live with the Epoch duration in the EPP element for (Re)Association request frames
I would go for #2 to be honest.
Thanks
Antonio
