Existing demarcation deployments

Currently, most subscribers connect to the carrier network for

(Voice/Video/Data) using customer premises equipment (CPE) for one of

several access technologies:

PSTN/ISDN

digital subscriber line (DSL)

Cable

T1/E1

T3/E3

OC3/STM1

The demarcation is not only the bridge but a translation point between theaccess network and the local Ethernet network. This adds a further level of

network deployment and maintenance complexity for both the carrier and

the subscriber.

PON

A passive optical network (PON)

System that brings optical fiber cabling and signals all or most of

the way to the end user.

Depending on where the PON terminates, the system can be

described as fiber-to-the-curb (FTTC), fiber-to-the-building (FTTB),

or fiber-to-the-home (FTTH).

PON consists of an Optical Line Termination (OLT) at the

communication company's office and a number of Optical Network

Units (ONUs) near end users. Up to 32 ONUs can be connected to

an OLT.

Passive simply describes the fact that optical transmission has nopower requirements or active electronic parts once the signal is

going through the network.

Ratified by IEEE as standard.

Broadband Passive Optical Network (BPON)

Cell based.

155 Mbps upstream/622 Mbps downstream Suffers from the very aggressive optical timing of ATM and the high

complexity of the ATM transport layer. High implementation cost.

Gigabit Passive Optical Network (GPON) is still evolving and still beingdiscussed by the ITU-T and FSAN bodies -

Supports multiple protocols through translation to the native Generic

Encapsulation Method (GEM) transport layer that through emulationprovides support for ATM, Ethernet and WDM protocols.

Bandwidth 2.5/1.25 Gbps optical components has delayed industrydevelopment of low-cost, high-volume GPON devices.

Ethernet Passive Optical Network (EPON)

Also know as Ethernet in the First Mile (EFM) Ratified by IEEE as 802.3ah EFM standard

Uses Ethernet as its native protocol and simplifies timing and lowers costsby using symmetrical 1 Gbps data streams using standard 1Gbps Ethernetoptical components. support for an extended Ethernet protocol simplifiesdevelopment.

Ethernet in the WAN PHY

802.3ah Ethernet:

Subscriber connects their Ethernet LAN directly to thesubscriber access network with a simple, familiar, and

native Ethernet interface.

802.3ah offers exactly the same networking model forEPON, Active/P2P, and copper and so further

streamlines deployment and reduces operational

complexity.

Ethernet promises to bring about the same revolution in access

networking th

at it created in enterprise networking: fast, simple,inexpensive, reliable, interoperable and ubiquitous connectivity

IEEE 802.3ah

802.3ah specifies:

Ethernet in the First Mile PON (EFMP), also known as EPON: Provides

symmetric point-to-multipoint 1-Gbit/s throughput over singlemode fiber up to either

10 or20km reach, depending on which of two modes (1310nm or 1490nm) is used.

Ethernet in the First Mile Fiber (EFMF): Provides 100- to 1000-Mbit/s point-to-

point connections over singlemode fiber up to 10km reach.

Ethernet in the First Mile Copper (EFMC): Uses Category 3 voice-grade copper

twisted-pair to provide point-to-point connections. Two options provide 10-Mbit/s

throughput up to 750m with passband VDSL technology, or2 Mbit/s up to 2700m

with baseband SHDSL technology.

802.3ah also supports hybrid solutions, and, most importantly, it specifies anOAM capability that makes Ethernet access a carrier-grade technology.

Not a true broadcast as only 1 node can transmit at a time.

P2P EFM Copper (EFMC)

What is it?

Uses a single copper pair at a minimum.

Typically uses ITU G.SHDSL specification for2.3-Mbit/s symmetricDSL services over copper.

Minimum of 10 Mbit/s over750m and 2 Mbit/s over at least 2,700m.

These speeds are the minimum and are quite conservative mostimplementations are likely to be able to exceed them.

Bonding multiple copper pairs to give higher bandwidth servicesover longer distances. The International Telecommunication Union,Standardization Sector (ITU-T) has a series of G. Recommendations(G.bond or G.988) that allows standard xDSL technology to run athigher speeds over multiple bonded pairs.

Eight copper pairs bonded together can provide a maximumbandwidth of40 Mbit/s symmetrical

Restrictions:

Limited to distance versus bandwidth ratio.

Can be bonded with other pairs for higher throughput.

802.3ah continued

Operations Administration and Maintenance (OAM) special purpose cells usedto monitorVirtual Circuits

What is it?

802.3ah includes mechanisms for link operation and health monitoring, faultisolation, and remote CPE management.

Tthe OAM channel utilizes an insignificant amount of bandwidth even though itoperates in-band. Only a maximum of 10 OAM packets per second can betransmitted from the CPE to the CO.

Operates as a Layer2 protocol, 802.3ah OAM passes P2P from CPE to CO anddoes not require an IP address unlike SNMP. Reduces the burden of IP addressmanagement on the carrier.

Reduces network administration for the Service Provider.

Fault indication/isolation capabilities such as Link Fault, Last Gasp,C

ritical Event,and Local and Remote Loopback are supported by the standard, equipmentservice configuration capabilities like bandwidth provisioning, SLA management,sub-50ms redundancy, and firmware downloads are implemented ascarrier/vendor-specific extensions.

Carrier/vendor extensions are highly important. Sub-50ms redundancy, forexample, means that 802.3ah Ethernet access can offer link restorationcapabilities that equal or exceed those of Sonet/Synchronous Data Heirarchy.

802.3ah cont

Quality of Service (QOS)

How does it work?

802.3ah is essentially a transport protocol, designed to move databits from A to B across an access network reliably and at a definedrate. Its QOS capabilities thus relate mainly to this task, rather thanto the end-to-end delivered user service. So the user QOS isnormally implemented by the end devices, and these can be the802.3ah-implementing devices or separate devices, such as anEthernet switch or a Sonet switch.

EPON is a little more complicated than the P2P forms of 802.3ah, asthe uplink is gated and only one remote station can transmit at atime, so it is not a standard form of Ethernet transmission from this

point of view.

Control is centralized by the OLT, and the OLT executes dynamicbandwidth allocation algorithm in order to control the bandwidth.And the efficiency of the QOS depends a lot on the quality of thisalgorithm. It is one of the key elements of this service to be able to

assign and configure the algorithm for this service.

CO service with EFM

Ethernet in the First Mile can be implemented at the edge for

whatever subscriber service is needed (i.e. IP, ATM or

Sonet).

The MEF has defined several generic types of Ethernet

service: two important ones are E-Line service and E-LAN

service.


27/43

27 Confidential

E-Line service

Ethernet Line service provides an Ethernet virtual connection,(EVC) between two points across a metro Ethernet network.

Can provide a clear 10-Mbit/s Ethernet connection between two

user network interfaces (UNIs orCPEs).

Full-duplex connection between two points providing symmetrical

bandwidth, but no performance guarantees. E-Line service may provide performance guarantees such as

Committed Information Rate (CIR) and Committed Burst Rate

(CBR), as well as implement delay, jitter, and packet-drop

metrics.

Multiplexing of EVCs onto one physical CPE port is possible,creating a service that is analogous to Frame Relay PVCs.

E-Lan

E-LAN is a multipoint-to-multipoint service, where one UNI orCPE can communicate with all the other UNIs on the same

EVC (see Figure 5).

E-LAN requires only one EVC at each site to achieve multisite

connectivity, whereas Frame Relay, for example, would

require the creation of multiple PVCs at each location, one for

each possible point-to-point connection within the group.

Carriers can make the provision of varying subscriber services

much easier, and they have greater flexibility to add revenue-

generating services when desired.

For the subscriber, the separation of access and service

makes it easier to select a provider and migrate to newservices
