[Softwires] FW: New Version Notification for draft-guo-softwire-sc-discovery-00

[Sheng Jiang <shengjiang at huawei.com>]

Dear all,

A new draft draft-guo-softwire-sc-discovery has been submitted to softwire
WG. It proposes a general softwire (tunnel) concentrator discovery
mechanism. It is generic to server different kinds of tunnel/softwire
concentrator auto dsicover scenarios includes the scenario of
draft-dhankins-softwire-tunnel-option.

Please view and comments. Many thanks.

> Abstract:
> Several types of Carrier-Grade-NATs (CGNs) have been proposed 
> to simplify IPv4/IPv6 transition of the edge network by 
> integrating tunnels and NAT. A very common scenario is that 
> many users set up softwires (i.e. tunnels) to a softwire 
> concentrator for public or private access services. In order 
> to establish softwires successfully, a new mechanism is 
> required to enable users in the edge network to discover the 
> information of the concentrator. This document describes how 
> a host or CPE (Customer Premises Equipment) discovers the 
> remote softwire concentrator or CGN in a hub and spoke 
> network using DHCP. 
> Based on two new Softwire Concentrator or CGN Discovery DHCP 
> Options, proposed in the document, a user can obtain softwire 
> concentrator or CGN information and then set up a tunnel to 
> the softwire concentrator or CGN.
