3 IETF68 CCAMP Background GMPLS Control of Ethernet Forwarding (GELS) concluded that before we adapt GMPLS to Ethernet bridging we need an IEEE compliant data plane. One data plane that is emerging is Provider Backbone Bridges Traffic Engineering (IEEE802.1Qay). The Acreo implementation references only IEEE802.1Q standard Other IEEE Ethernet Switching paradigms may be defined in the future. IEEE802.1Qay is what we initially propose to control remaining flexible for other paradigms.
