For the purpose of this document, subnetworks are defined as virtual topologies that span connected network regions bounded by encapsulating border nodes. These virtual topologies may span multiple IP and/or sub-IP layer forwarding hops, and can introduce failure modes due to packet duplication and/or links with diverse Maximum Transmission Units (MTUs). This document specifies a Subnetwork Encapsulation and Adaptation Layer (SEAL) that accommodates such virtual topologies over diverse underlying link technologies. This document defines an Experimental Protocol for the Internet community.

For the definition of Status, see RFC 2026.

For the definition of Stream, see RFC 4844.
