My first thought would be to keep it simple and use a tag per address. Plenty of tag namespace. Den tors 20 juni 2024 11:35Mauro Levra skrev: > > Instead of dedicating a bit to the enterprise flag, we could also > > define a specific tag for the IANA-PEN, then the enterprise number > > itself fo

Hi Mauro, Instead of dedicating a bit to the enterprise flag, we could also define a specific tag for the IANA-PEN, then the enterprise number itself followed by its private payload. This way we keep the full range of value tags at the cost of 2 extra bytes per packet. Presumably we will need a

[Wireshark-dev] Add enterprise-specific options to Extended PDU protocol header

2024-06-20 Thread Mauro Levra via Wireshark-dev
Dear all, I have been looking for a way to store 4G and 5G RAN/Core signaling traces in pcapng. Its lack of support for 5G traces made me abandon gsmtap and focus on the exported_pdu protocol that allows me to specify the dissector to apply and hence can handle any protocol. The TLV approach f
