Ethernet service model

A service is what a CE sees (UNI-to-UNI)

UNI is the demarcation between service provider and Customer responsabilities

Dedicated to a single subscriber

Standard Ethernet compliant with IEEE802.1D/Q and IEEE802.3

CE may be any kind of customer equipment as a switch or routeur

Classification :- flow identification based on the Ethernet frame :

- (Port and L2 header (SA, DA, Ethertype, VID, PCP)

- define CoS and process

- SVLAN associated to the frame

Metering :- rate measurement

- define drop precedence (green, yellow, red)

Marking :

mark CoS or Drop Precedence in L2 (PCP bits)

Policing :

Ingress rate limitation by immediate Red frame/packet dropping

1.6.1. VCAT

37

37

Concatenation

Compliant to G.707

Virtual Concatenation (VCAT): ie. VC3-2v, VC4-7v- For a better bandwidth adjustment the VC can be concatenated

- requires a specific processing at both ends of a connection. No impact on

intermediate nodes

- resulting aggregated channel is named a VC group (VCG)

- channels of the same VCG may follow different paths, resulting in different

propagation delays. The receiving node must store the different members in order toperform realignment

- Multi-Frame Indicator (MFI) and Sequence Nbr (SQ) in the H4 byte provide thenecessary information for a successful alignment;

1.6.2. LCAS

38

38

LCAS Link Capacity Adjustment SchemeCompliant to G.7042 Link capacity adjustment scheme (LCAS) for virtualconcatenated signals

The GFP2500 card enables activation of the standard protocol "Link CapacityAdjustment System" (LCAS) independently on each of the 22 VCGs.

LCAS is useful to : Dynamically add or remove VC members from a VCG without deactivating the VCG(making it a hitless operation for traffic)

Dynamically adjust the available bandwidth when alarms are triggered ON/OFF on theVC members of a VCG. The bandwidth of every VC under failure is subtracted from theVCG bandwidth. Hence, in case of failures the VCG continues to forward traffic as long asthere is still at least one operational VC

Without LCAS :

The GFP2500 card requires deactivation of a VCG before VC members can be added orremoved (it forces a traffic interruption)

A VCG becomes completely broken as soon as an alarm is triggered on at least one VCmember. Plus, it becomes operational again only once no VC is under failure anymore.

GFP Generic Framing Procedure

GFP (G.7041) provides a genericmechanism to adapt traffic from higher-layer client signals over a transportnetwork

Two modes of client signal adaptationare currently defined:

A packet-oriented mode, referred toas Frame-mapped GFP (GFP-F)

A block-oriented adaptation mode,referred to as Transparent GFP (GFP-T)

Higher Layers

Ethernet PPP FC Other clients

GFP Generic Framing Procedure

GFP-F protocol is used

There are 8 bytes header and 4 optional bytes FCS

If there is no Ethernet frame, IDLE GFP frames are sent tomaintain the link synchronisation

Ethernet - OAM OAM-CC 802.1ag

OAM Operation Administration and Maintenance

The OAM function in the GFP card, is used to supervise thecustomer traffic. It is based on the IEEE-802.1ag

This function consist in sending and receiving specific messagesto monitor customer traffic and to known the network status.

These frames are called: CC:Continuity Check.

Probe Source OAM-CC

Probe Sink OAM-CC

The number of source probes is limited to 256 per card

the number of sink probes is limited to 256, per card. The frame multicast OAM is not distributed on the UNI-N port (customer), it is

distributed on NNI ports.

The OAM CC multicast MAC address is by default: 01-80-C2-00-00-67.

The OAM-CC function manages 2 supervision alarms :

OAM Degraded : in this case it is the loss of one up to three consecutive CC frames

OAM Defect : in this case it is the loss of at least four consecutive CC frames

The period between two OAM frames is configurable : 10s by default.

Notes :

The periodic OAM defect, can mean that network capacity for the VCG are not adjusted, and thatcongestions appear (example : a VC link loss in a VCG with LCAS).
