Increasingly, research and education communities are seeking to run high performance networking applications across the Janet infrastructure, such as high bandwidth, real-time media or data streaming, low latency haptic applications, or bulk transfers of research data in the order of Terabytes or more. The Janet End-to-End Performance Initiative (e2epi) group has been created to facilitate sharing and discussion of information and topics related to end-to-end network performance including, but not limited to, applications and data transfer tools, system tuning, site network architectures, and performance measurement. It is expected that members of this group would include end users and communities, network operators/administrators within Janet-connected sites, and academic network researchers, but all interested stakeholders are welcome.  The aim is to raise awareness of issues/factors affecting e2e performance, and to discuss and share best practices.
