Hi all,

The motivation of this draft is as follows:

"To facilitate the incremental deployment of the MPLS-SPRING technology, this document describes a mechanism which allows the outermost LSP be replaced by an IP-based tunnel. This mechanism is much useful in the MPLS-SPRING-based Service Function Chainning (SFC) case where only a few specific routers (e.g., Service Function Forwarders (SFF) and classifiers) are required to be MPLS-SPRING-capable while the other immediate routers are just required to support IP forwarding capability. In addition, this mechanism is also useful in some specific Traffic Engineering scenarios where only a few routers (e.g., the entry and exit nodes of each plane in the dual-plane network ) are specified as segments of explicit paths. In this way, only a few routers are required to support the MPLS-SPRING capability while all the other routers just need to support IP forwarding capability, which would significantly reduce the deployment cost of this new technology. Furthermore, since there is no need to run any other label distribution protocols (e.g., LDP), the network provisioning is greatly simplified, which is one of the major claimed benefits of the MPLS-SPRING technology."

The major changes since -03 versions can be found at http://tools.ietf.org/rfcdiff?difftype=--hwdiff&url2=draft-xu-spring-islands-connection-over-ip-04.txt

Any comments are welcome.

Best regards,
Xiaohu

> Abstract:
>    MPLS-SPRING is an MPLS-based source routing paradigm in which a
>    sender of a packet is allowed to partially or completely specify the
>    route the packet takes through the network by imposing stacked MPLS
>    labels to the packet.  To facilitate the incremental deployment of
>    this new technology, this document describes a mechanism which allows
>    the outermost LSP be replaced by an IP-based tunnel.
