Abstract

Techniques for tunneling Layer 2 ethernet frames over a connection tunnel using the MASQUE protocol are described herein. The MASQUE protocol may be extended to include a new entity, configured to proxy ethernet frames using a MASQUE proxy connection, and an associated CONNECT method, CONNECT-ETH. Using the extended MASQUE protocol, an Ethernet over MASQUE (EoMASQUE) tunnel may then be established between various networks that are remote from one another and connected to the internet. An EoMASQUE tunnel, established between separate remote client premises, and/or between a remote client premise and an enterprise premise, may tunnel ethernet packets between the endpoints. Additionally, a first EoMASQUE tunnel, established between a first client router provisioned in a first remote client premise and an EoMASQUE proxy node, and a second EoMASQUE tunnel, established between a second client premise and the EoMASQUE proxy node, may tunnel ethernet packets between the first and second client premise.
