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. Jon Brown 2211 N.

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

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 Source: Light Reading

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

Death by ‘Ether’

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.

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.

Common Ethernet Transport Misconceptions

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.1731 - OAM functions and mechanisms for Ethernet based networks 802.1ag - Connectivity Fault Management

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

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

Putting It All Together

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

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.
