IT’S HERE

1. IT’S HERE Bandwidth Technologies

2. Agenda 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)

3. 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)

4. 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

5. 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

6. 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

7. 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

8. 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

9. Multi Loc: Point to Point T1 Networks

10. 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

11. Multi Loc: VPN VIA Public Internet

12. 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)

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

14. 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

15. 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

16. 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
