• 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
