Technical Summary The document sets normative requirements for Diameter overload control solutions. The existing Diameter mechanisms for an overload control are not sufficient for a practical solution. The document also goes into lengths explaining why Diameter overload control functionality is needed and describes the limitations of the existing mechanisms in the Diameter Base Protocol. Working Group Summary The working group reached a consensus on the document. The discussion was extensive. Since this document is a requirements document, possible technical solution space issues are left for future documents and discussions. There is an obvious decision point ahead that got quite a bit of attention, which relates to the dissemination of the overload control information: whether an explicit overload application is needed for proper end-to-end signaling semantics or whether everything is piggybacked on top of existing signaling between adjacent peers in hop-by-hop fashion. However, this is for the solution space and the requirements document currently allows both approaches. Document Quality The document has greater industry interest behind, specifically from the cellular industry. Since the document is a requirement document there are no standardised solutions available yet due to the absence of the protocol specification. There is definitive interest from both operators and vendors to have a standard solution for Diameter overload control. The requirements document has been extensively reviewed by the 3GPP CT4 working group, which is the main AAA protocol group in 3GPP. Personnel Jouni Korhonen is the document shepherd. The responsible area director is Benoit Claise. No IANA experts required.
