[Softwires] Fw: New Version Notification for draft-cui-softwire-pet-01

["Yong" <yong at csnet1.cs.tsinghua.edu.cn>]

Hi, Softwire Folks,

We have updated the IPv4/IPv6 Coexistence Framework (PET)
to its -01 version and posted its use case on IPv6-to-IPv4
as follows.

>Abstract:
>IPv4 and IPv6 are expected to coexist for a long period.  Currently,
>there are many IPv4/IPv6 transition/coexistence technologies, which
>can be generally divided into two categories: translation and
>tunneling.  Both translation and tunneling have limitations and
>application scopes.  In some typical transition scenarios, tunneling
>and translation are needed at the same time.  In addition, there may
>be multiple network devices capable of doing translation or tunneling
>along the end-to-end path.  It's important to choose particular
>device(devices) for doing translation or tunneling.
>
>This draft presents an IPv4-IPv6 transition/coexistence framework
>named PET (short for Prefixing, Encapsulation and Translation).  PET
>is a network side solution which includes fundamental elements needed
>in various transition scenarios.  In PET framework, signaling is
>required for transition devices to exchange necessary information and
>negotiate how to do combine transition and tunneling cooperatively.
>This draft also addresses how to deploy PETs and analyze the
>advantages and disadvantages of typical transition technologies that
>PET may adopt.
