Re: [alto] Proposed Path Aware Networking Research Group in Prague

Hi Brian and all,

It is definitely closely related and I feel the target of PAN fits 
perfectly with the latest efforts within ALTO WG, in particular the path 
vector extension, which aim to provide fine-grained path information to 
higher-layer orchestrators/applications.

Our group would be very interested in PAN RG and we would try our best 
to attend.

Thanks for the information and wish you all the best!

Regards,

Kai
