Historically Speaking (not at the very beginning but close) IPX/IP Gateway – server 56k modem v.35 To the internet

Historically Speaking (not at the very beginning but close) Small text only s 56k was really all that was needed Possible some small files upload and downloaded via FTP or Bulletin Board systems – Remember Wildcat BBS?

Historically Speaking (Middle ages) T1 or E1 V.35

Historically Speaking (Middle ages) Web browsing! yeah Still relatively small files The beginning of downloading larger files – Music – Software – Browser wars

Historically Speaking (Middle ages/today) T1 or E1 DS3 or E3 DSL/Cable

Historically Speaking (Middle ages/today) Large file downloads – Movies Streaming! – Movies – Music Social Media – Facebook – LinkedIn

More Bandwidth Please

About Ethernet Designed for LAN communications. – Simple – no guarantee of delivery of data – Easy to implement – Everyone (manufacturers) makes Ethernet devices – Cheap!!!! – Dominant LAN protocol everywhere

About Ethernet (cont.) Hardware for Ethernet – Twisted pair (copper) – limited to 300 feet (100m). Has been around for years and is everywhere.

About Ethernet (cont.) Hardware for Ethernet – Fiber Optic – Limited to around 60 miles (100km). Initially used only for connections between large Telco exchanges. Eventually installed in every open trench. Started out as expensive per foot but is below the price of copper in some cases today.

Fiber optics is the Game Changer Why is Fiber the game changer? – Ethernet was limited to 300 feet over copper, T1s could be extended much further over copper. – Fiber provides more bandwidth than copper. – Copper (Cu) is getting very expensive, fiber is getting more economical. – Copper lines can erode but Fiber last longer, better investment over time.

Ethernet for Service Providers Eureka! Ethernet over fiber can be used to deliver greater bandwidth for lower cost then traditional Telco Services – T1/E1 – T3/DS3

The Wild Wild West Some service providers used managed media converters to deliver Ethernet over fiber. – Bandwidth limiting but little else. – No real accountability. – Could not guarantee complex SLAs. – Could not guarantee consistency when more than one carrier is involved in delivering the service. These issue were resolved in the older Telco circuits and also part of the reason for their high cost.

Cost? Why are traditional Telco services so expensive? – Voice technology used for data Voice tech requires timely delivery of information. – Accountability and manageability SLA (Service Level Agreements). – Dedicated Circuit vs Packet routing Bandwidth through the carrier’s network.

Quick word about Packet switching

The Birth of MEF and Carrier Ethernet Service providers wanted a standard that would guarantee: – They could meet SLAs – Consistency when circuits crossed multiple Carrier’s networks Manufacturers wanted a standard that would guarantee: – That they were investing time and money in a product that would meet the needs of the Carrier – They could sell there equipment to a variety of Carriers Carriers wanted: – A choice of hardware manufacturers – Interoperability between manufacturers equipment

Carrier Ethernet over ?? Fiber – yes fiber has played a big role but MEF – Carrier Ethernet is not confined to one media.

MEF – Carrier Ethernet Five core attributes of Carrier Ethernet

Attribute 1: Standardized Services E-Line, E-LAN provide transparent, private line, virtual private line and multi-point to multi-point LAN services. A common service providing globally & locally via standardized equipment Requires no changes to customer LAN equipment or networks and accommodates existing network connectivity such as, time- sensitive, TDM traffic and signaling Ideally suited to converged voice, video & data networks Wide choice and granularity of bandwidth and quality of service options

Attribute 2: Scalability The ability for millions to use a network service that is ideal for the widest variety of business, information, communications and entertainment applications with voice, video and data Spans Access & Metro to National & Global Services over a wide variety of physical infrastructures implemented by a wide range of Service Providers Scalability of bandwidth from 1Mbps to 10Gbps and beyond, in granular increments

Attribute 3: Reliability The ability for the network to detect & recover from incidents without impacting users Meeting the most demanding quality and availability requirements Rapid recovery time when problems do occur, as low as 50ms

Attribute 4: Quality of Service Wide choice and granularity of bandwidth and quality of service options Service Level Agreements (SLAs) that deliver end-to-end performance matching the requirements for voice, video and data over converged business and residential networks Provisioning via SLAs that provide end-to-end performance based on CIR, frame loss, delay and delay variation characteristics

Attribute 5: Service Management The ability to monitor, diagnose and centrally manage the network, using standards-based vendor independent implementations Carrier-class OAM Rapid service provisioning
