1. MEF Ethernet Traffic Parameters draft-dimitri-mef-ethernet-traffic-parameters-00.txt IETF65 - Dallas - Mar’06

2. Why ? Demand from OIF Provide traffic parameters for Ethernet service provisioning across domain boundaries Presented in CCAMP but status to be revisited depending on GELS evolution l2sc Ethernet LSP

3. Overview Per [RFC3471], inclusion of technology specific parameters in SENDER_ TSPEC and FLOWSPEC specific objects Ethernet traffic parameters [MEF.10] used when in Label Request object –LSP Switching Type: L2SC –LSP encoding type: Ethernet SENDER_TSPEC/FLOWSPEC object –Ethernet link type (switching granularity) –MTU value –Bandwidth Profile: set of traffic parameters Committed Rate: described in terms of the CIR (Committed Information Rate) and CBS (Committed Burst Size) Excess Rate: described in terms of the EIR (Excess Information Rate) and EBS (Excess Burst Size) Color mode (CM): "color-aware" or "color-blind" property is employed by the bandwidth profile Coupling flag (CF): choice between two modes of operations of the rate enforcement algorithm

4. Sender_Tspec Format Specific TLV defined for Bandwidth Profile: : 8-bit vector of flags,,, each over 32 bits, unit of bytes and encoded as IEEE single-precision floating-point number [RFC1832] Ethernet SENDER_TSPEC object (Class-Num = 12, Class-Type = TBA) 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Length | Class-Num (12)| C-Type (TBA) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Switching Granularity | MTU | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | ~ TLVs ~ | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

5. Next Steps Need for signaling multiple CoS per EVC ? –Requires combination with DS-TE Status of document will depend on GELS evolution As of today “informational” status
