1. Ethernet Transport Services
RICA
May 6, 2010
Goal of my Presentation is to provide a view from the Telco through the eyes of a Consultant. To share the State of the Industry on a vendor agnostic view
Open with discussion of 8 years ago at the ISP Summit. Talk on ATM VS.. Eth-discuss how things Change, how they Stay the Same
Talk about how tech. today will learn Eth Because technology is Similar in Concept and goals, just-different in protocols and Acrynontalk about learning Curve
Discuss Washington DC visit withlarge Carriers and how they are fighting with the Same IssuesTalk about however) network has different requirements and what works for one Company May not be the Solution For another Company
Discuss deployment options.. Overlay networks while leaving regulated Services on Existing transport. Although Most Companies don’t core about Regulates.

2. Overview Why Ethernet, Why Now? Death by “Ether”
Services Currently Provided over Ethernet $$
Common Ethernet Misconceptions
Putting it All Together
What is SONET?
-What does SONET do well?
-So If SONET works, why change? What can’t SONET do well?
What is the Solution?
-Enter the Data Chumps and their solution known as Ethernet
History of Ethernet
Where did the term Ethernet come from?
-What does Ethernet Do well? Why Ethernet why now?
Comparison of Ethernet features to replace SONET features
-UPSR/BLSR type comparisons with Ethernet
Recovery mechanisms available
Timing options available.
-Can Ethernet be provisioned for connection orientated services?
Acronym soup- MPLS, MPLS-TE, T-MPLS, Q.8032, EAPS, PBB, PBB-TE RSTP
The MEF group and what it is doing.
Is 10Gig Enough???
-10 Gig Ethernet Technologies
-40 gig? 100 Gig? Beyond?????
Other Transport options
-DWDM and POTS ?
What to be aware of when selecting a new Transport network Real life Horror stories
Mac address scaling
How does the vendor handle video (multicast routing limitations, IGMP snooping limitations etc)
OAM &P
Quality of Service – some vendors will quote inferior cards to try to compete with pricing
General Concerns when deploying Next Generation Transport
-Remember this is transport, keep Internet off this box if at all possible.
The genesis of these products typically involve ‘some’ data chump mentality
Actually test what the vendor says is possible. Some vendors post throughput but can’t achieve it in the field
Pre-qualify fibers for 10Gig interfaces

4. The Pricing Challenge
Bandwidth requirements will grow faster than revenue
Historic Capacity Planning Techniques are useless
Customers expect more bandwidth for approximately the same cost
Upstream bandwidth Requirements are currently doubling every 18 months

5. The Point Is…
Telco’s continue to offer more broadband services such as high-speed Internet, IPTV, and VOD
New applications that will require more bandwidth are coming
The consumers’ thirst for higher data rates is increasing
There must be a way to transport/deliver this content to the service provider

6. Death by ‘Ether’

7. Challenging the Capabilities of SONET
Current network requirements are revealing SONET scalability Issues
- Subscribers requesting 200Mb, 300Mb, 400Mb and even 1Gb/s circuits
- Next Generation SONET NG-SONET provides some relief inefficient mapping of STSs (Virtual Concatenation, etc)
Due to un-awareness of upper layer protocols, SONET not as effective for IP Video
- RPR Rings are limited at 1.2Gb/s, and most video head ends are passing this limit.

8. Additional SONET Challenges
Lacks dynamic “traffic engineering” capabilities of newer Transport Technologies
Carrier Ethernet can dynamically select new paths based on bandwidth, time of day, etc. Not just either “up” or “down” interface status
Incremental increases in subscriber bandwidth is challenging with SONET
In-efficient use of bandwidth - reuse of available bandwidth difficult if not impossible with some platforms.

9. Growth in Ethernet Business Services
Applications for Carrier Ethernet Services
Transparent LAN Services
Data Center / Disaster Recovery/SAN
Telemedicine/Digital Imaging
Telepresence
Telecommuting
3G and 4G Mobile Backhaul
IP Video, Voice, and Data (Triple Play)

10. Common Ethernet Transport Misconceptions

11. Top Ethernet Myths Myth 1 - Ethernet is not optimized for the WAN
FALSE Not initially optimized for the WAN, but that is changing with the works of the ITU, IEEE, MEF, many vendors, etc
Myth 2 - Limited troubleshooting and fault management capabilities
FALSE Y OAM functions and mechanisms for Ethernet based networks
802.1ag - Connectivity Fault Management

12. More Ethernet Myths
Myth 3 - Ethernet is connectionless and best effort
FALSE Ethernet can be provisioned as connection orientated with protocols such as 802.1ah (PBB), 802.1Qay (PBB-TE)
Myth 4 - Ethernet does not handle timing
FALSE Synchronous Ethernet – ITU-T G.8262 recommendation provides synchronization of packet networks for time-sensitive services

13. Ethernet Myths
Myth 5 - Ethernet can not provide sub 50ms switching and recovery
FALSE G.8031 and G.8032 specify fault-tolerant architectures and ability to achieve 50ms failover between primary and secondary paths.
All PC and computes Start Ethernet, why not leave then that way and eliminate the Conversions

14. Putting It All Together

15. Carrier Ethernet Benefits
Cost Effective
Simplified Network
Reduces number of protocol conversions
Ethernet end point to Ethernet End Point
Scalable to 10Gb/s, 40Gb/s, 100Gb/s and beyond
Provides Carrier Class Monitoring, Alarming, Quality of Service, and troubleshooting tools

16. So Lets Bring Back ATM (Sort of)
The Learning Curve isn’t as much as expected in “Most” cases to go to Ethernet Transport
Many vendors make it “feel” like traditional TDM/ATM/SONET
The Terminology is the same
PIR, CIR, EIR,SLA
Timing
Fault Isolation and Alarming
In the end, we are accomplishing SONET services with more flexibility and lower cost.
