The QUIC working group develops a standards-track specification for
a UDP-based, stream-multiplexing, encrypted transport protocol. Members of the MAMI consortium are activity contributing to the QUIC working group focusing on manageability of the network QUIC transport semantic in stateful devices in the network.
- Manageability of the QUIC Transport Protocol
- Applicability of the QUIC Transport Protocol
Path Layer UDP Substrate (PLUS)
Members of the MAMI consortium and EAB have proposed a Path Layer UDP Substrate (plus) in the IETF, initially called Substrate Protocol for User Datagrams (SPUD). PLUS is aiming for a UDP-based encapsulation protocol to allow explicit cooperation with middleboxes while using new, encrypted transport protocols. At IETF-92 a non-working group forming SPUD BoF was held with Mirja Kühlewind acting as co-chair. Further Brian Trammell and Joe Hildebrandt, who is a member of MAMI’s EAB, held presentations. At IETF-96 Mirja Kühlewind, Brian Trammell, Joe Hildebrand, and Ted Hardie (Google) proposed a working group forming BoF, not resulting in an active working group. Efforts to support middelbox statement as well as initial use case for middlebox signaling such as diagnosibitly are on-going.

Transport Services (taps)
The TAPS working group will develop an (abstract) interface for applications
to make use of Transport Services without the need to have detailed knowledge about the transport protocol used or current network conditions and potential middlebox impairments. The initial working document is authored by members of the MAMI Consortium.

Automated Certificate Management Environment (ACME)
The Automated Certificate Management Environment (ACME) working group took up work from the Limited Use of Remote Keys (lurk) effort that hold a BoF meeting at IETF-96.
- Use of Short-Term, Automatically-Renewed (STAR) Certificates to address the LURK problem
Transport Layer Security (tls)
The Transport Layer Security (tls) working group is currently working with a design team on optimizations to support scenarios that require a connection ID for UDP based transmissions.

IAB IP Stack Evolution Program and IAB Privacy and Security Program
Brian Trammell is the Program Lead for the Internet Architecture Board’s IP Stack Evolution Program; Mirja Kühlewind is a member of the Program. The Program discusses efforts within the IETF and IRTF to advance the architecture of the Internet protocol stack, related to maprg (see below) and PLUS (see above).
The Privacy and Security Program, where Brian Trammel is a member, focuses on privacy and security in the IETF, including support of pervasive encryption of application data as well as the transport header as well as the tussle between privacy to prevent pervasive monitoring and network management functions.

IRTF Measurement and Analysis for Protocols Research Group (maprg)
Since IETF-96 maprg is an IRTF research group focusing on Internet measurement to explore middlebox impairments and other phenomena that can influence protocol engineering and practice. Mirja Kühlewind and Dave Plonka are co-chairing the proposed research group.
maprg met first at IETF-97, howver, also already met twice at IETF-96 and IETF-95 as being a proposed reserach group and is the follow-up activity of the proposed hopsrg (How ossified is the protocol stack? research group) that was initially discuss at the IAB Workshop on Stack Evolution in a Middlebox Internet (SEMI) in January 2015 in Zurich. hopsrg also held two meeting at IETF-93 and IETF-94.
