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

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

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

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) | Length | Class-Num (12)| C-Type (TBA) | | Switching Granularity | MTU | | | ~ TLVs ~ | |

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
