Technologies for Bandwidth– Single Location

• DSL/Cable• T1/Bonded T1• DS3/OC-N• Ethernet Over Copper (EoC, EoFM)• Ethernet Over Fiber (EoF)

– Multiple Location• P2P T1 Networks (Layer 2)• VPN VIA Public Internet• Carrier Provided Private VPN (MPLS – Layer 3 Managed

Routers)• Carrier Provided Ethernet (EPL/EVPL; E-Line, E-Lan, E-Tree)

Single Location: DSL

Advantages– Inexpensive– Relatively wide spread availability– Large bandwidth Download– Good for small business

Disadvantages– Small upload speeds– Distance sensitive– High latency/High Packet Loss– No SLA– Real time applications suffer (VoIP/Video/Remote Desktop etc)

Single Location: T1/Bonded T1

Advantages– Relatively Inexpensive– Wide spread availability– Symmetrical UP/DOWNLOAD– Good for medium/large business– Not distance sensitive– Low Latency/Packet Loss etc– SLA/Guaranteed Bandwidths– Proven Technology

Disadvantages– 1.5 – 12 Mbps maximum bandwidth– TDM rather than ETHERNET– Router expense

Single Location: DS3/OC-N

Advantages– Wide spread availability– Symmetrical UP/DOWNLOAD– Large Bandwidth– Good for Large business– Not distance sensitive– Low Latency/Packet Loss etc– SLA/Guaranteed Bandwidths– Proven Technology

Disadvantages– Fiber Based- expensive– TDM rather than ETHERNET– Router expense

Single Loc: Ethernet Over Copper (EoC)

Advantages– Relatively inexpensive– Symmetrical UP/DOWNLOAD

• G.SHDSL

– Large Bandwidth (up to 100 Mbps in some cases)– Good for Small/Medium/Large business– Scalable– Low Latency/Packet Loss etc– SLA/Guaranteed Bandwidths– Copper Based - no need for fiber

Disadvantages– Distance Sensitive– 30- 100 Mbps max– Not in all CO’s

Single Loc: Ethernet Over Fiber

Advantages– Symmetrical UP/DOWNLOAD– Very Large Bandwidth – Good for Large business– Scalable– Low Latency/Packet Loss etc– SLA/Guaranteed Bandwidths– Proven Technology

Disadvantages– Expensive– Equipment costs - CPE

Multi Loc: Point to Point T1 Networks

Advantages VIA T1– Easy-Hub and Spoke or redundant to other locations– Low initial router costs– Good for Medium/Large business– Low Latency/Packet Loss etc– SLA/Guaranteed Bandwidths– Proven Technology– Secure – private network– QoS from customer provided routers

Disadvantages– Expensive– Not very scalable– Equipment costs – CPE – as you grow– IT intensive– Single point of failure (hub)– Carrier cannot trouble shoot remotely

Multi Loc: Point to Point T1 Networks

Multi Loc: VPN VIA Public Internet

Advantages– Inexpensive– Relatively wide spread availability– Various method of connectivity (DSL,Cable,T1 etc)– Good for small business– Internet and VPN on same pipe

Disadvantages– Using the public internet – cannot guarantee speeds/throughput etc– Internet and VPN on same pipe(bandwidth constraints)– Security (need for firewalls at each location)– High latency/High Packet Loss– No SLA– Real time applications suffer (VoIP/Video/Remote Desktop etc)– Need to size connectivity appropriately

Multi Loc: VPN VIA Public Internet

Multiple Location: Carrier Provided Private VPN (MPLS – Layer 3 Managed Routers)

Advantages– Carrier becomes the hub– Wide spread availability– Various method of connectivity (DSL,T1,NxT1, EoC, DS3, Fiber, etc)-1.5 Mbps -10 Gb– Good for ALL business sizes– Internet and VPN available from same source– Private VPN/Secure(firewall off the cloud option)– SLA– QoS from carrier– Managed routers/network – Carrier can troubleshoot/change remotely- fast MTTR– Scalable– Network notification/bandwidth visibility

Disadvantages– If one HUB, single point of failure– Internet and VPN on same pipe(bandwidth constraints)– Security (need for firewalls at each location) or firewall off the cloud(carrier based)

Multiple Location: Carrier Provided Private VPN (MPLS – Layer 3 Managed Routers)

Multiple Location: Carrier Provided Ethernet Layer 2

Advantages– Carrier becomes the hub– Wide spread availability– Various method of connectivity (DSL,T1,NxT1, EoC, DS3, Fiber, etc)-1.5 Mbps-10Gb– Good for ALL business sizes– Layer 2-ETHERNET HAND-OFF regardless of medium– Private and secure– SLA to the customer PREM!– CoS from carrier- QoS is passed– Managed network – Carrier can troubleshoot/change remotely- fast MTTR– Scalable– More customer control– Network notification/bandwidth visibility

Disadvantages– If one HUB, single point of failure– Customer to provide routing/firewalling

The Ethernet Value Proposition

Metro Ethernet brings Customers and Providers value– Increases the cost efficiency of network capacity– E-Line, E-LAN provides transparent, private line, virtual private line and multi-point to multi-point LAN

services.– Simple, scalable, and flexible

Metro Ethernet is used for commonly needed applications– Ideally suited to converged voice, video and data networks– Encapsulation of Higher Layer Protocols for Efficient Transport– Between corporate sites separated geographically

(beyond the reach and function of Local Area Networks)

Advantages of Ethernet Services– Gigabit Ethernet based platforms are being widely deployed– Avoids bandwidth bottleneck– Incremental growth is not “linear” in cost– Service Level Agreements (SLA’s) that provide end-to-end performance matching the requirements of

voice, video, data, and internet over converged networks

Eliminates a layer of complexity from WAN access– Reduces configuration requirements– Plug-and-play technology– Simple migration path from low to high speeds

WHY ETHERNET?Ethernet favorably impacts every area of business:

Business application availability & performance

Service delivery and reach

User and customer satisfaction

IT resources and operations costs

Time to market for new applications

Subsequent impact on the top & bottom line
