2
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
Access Types
How do you define “Tier 1 Carrier” in
todays market place?
