• Ethernet QoS need Reservation• L2 LSP may be a Cost-effective Solution for Ethernet QoS
62nd IETF Minneapolis March 2005
Issue : RSVP may not be appropriate for Ethernet
• See draft-jaihyung-ccamp-arpsignal-00.txt for discussion – RFC2814, RFC2815, RFC2816 : RSVP for 802 Networks– Heaviness, weak security, operational difficulty, low industry support, etc..
• USE ARP !!! for L2 LSP setup

Why use ARP ?
• Ubiquitous deployment in all terminals– Receiver capability is not mandatory– LSP can be established in partial deployment
• Designed to carry MAC address– Appropriate if MAC address is used for Label
• New Session auto triggering of ARP– Connection to unknown terminal ARP
62nd IETF Minneapolis March 2005
Incorporation of Routing
• Use Flood Routing !! technique• Establish LSP via optimum path for QoS

Next Actions
• Call for participation on L2SC issues– Request for review/feedback
• Call for contribution to the 3 drafts– Send your proposal, that we can add
• More drafts to come– Ethernet based Access Network– Core network implementation using High-
performance Ethernet Bridges
