Re: [IPsec] IPsec maintenance/extensions WG, summary so far

["Peng Yang" <[e-mail]>]

Hi, Pasi and all:

 Sorry for late post. And sorry for Pasi if you received multiple copy
of this mail.

My interest list has following items.

 [ECR] IKEv2 session resumption / optimizing IKEv2 handshake when
         connecting again to same peer/cluster of peers (possible
         starting point: draft-sheffer-ipsec-failover)
 [ECR] MEXT: interaction between IPsec and Mobile IP, Mobile IP
          specific extensions to IPsec
 [ECR] Using GRE "key" header field as IPsec traffic selector (possible
          starting point: draft-ma-softwire-ipsec-gre-demultiplexing-ps)

 Thanks a lot
 Cheers,

 Peny
