The Business
Value of Ethernet
Services

• extend low-cost, LAN-based Ethernet to the WAN
• transport voice, data and video applications
• deliver point-to-point or multipoint services
• use dedicated or virtual connections
• use various access methods
– high-speed fiber
– DSL
– cable
– wireless
– T1 lines
• support speeds from 1Mbps to 10Gbps+

E-Line, or Ethernet Private Line
(EPL) Service
EPL is a point-to-point service using dedicated bandwidth between locations.
Application
EPLs are ideal for bandwidthintensive applications and are the most popular Ethernet service due to their simplicity.
Variation
A point-tomultipoint (hub-andspoke) variation using shared bandwidth is called an Ethernet
Virtual Private Line (EVPL) service.
Toolbox

E-LAN, or Ethernet LAN service
E-LAN enables any-to-any communication among all customer locations via a multipoint-tomultipoint Ethernet connection.
Application
An E-LAN can be used to create a
Transparent LAN Service, such as a multipoint Layer 2 VPN.
Variation
E-Tree multipoint connectivity ( hub and spoke ) is used for broadcast applications where services flow from a centralized point.

• adoption rates soaring
• widespread use across domains:
– wide area
– metro
– access
• increasing demand for ever greater speeds
– 100Mbps ‒ 10Gbps
– some 40Gbps for WAN applications

High
Bandwidth
Scalability
Ethernet usually is deployed from 10MBps to
10Gbps. But speeds up to 100Gbps are possible and carriers now are looking at supporting 400Gbps.
Ethernet bandwidth can be increased on a granular basis up to the physical port size. In contrast, growing a TDM network from DS1 (1.5Mbps) to DS3
(45Mbps) to OC3 (155Mbps) requires forklift upgrades .
Low
Latency
Low Cost
Ethernet is switched rather than routed, so it has low latency and generally is considered preferable to router-based protocols, such as MPLS and VPN in settings where milliseconds are crucial.
Ethernet handles growing speed and bandwidth requirements for less. A T1 delivering 1.5Mbps costs around $300 per month, while 3Mbps asymmetrical
Ethernet costs about the same. That's twice as much bandwidth for the same price.
Toolbox

Private Line
Replacement
Ethernet replaces private lines using T1 circuits, frame relay or ATM .
Dedicated Internet
Access
Ethernet virtual private lines connect each customer location over a single physical link to the ISP.
Multilocation
Interconnection
Ethernet virtual connections over a single physical link are a good choice for multiple locations .
Data Center
Interconnection
High data rates needed between data centers make
Ethernet an good choice.
Cloud Connectivity
Ethernet supports network needs of cloud services: high bandwidth, low-latency, security and scalability.
Storage
Replication
Ethernet's speed means the replication and backups are done in seconds or minutes, rather than hours.
BC/DR
Voice/Video/
Imaging
Ethernet can be used as a secondary network so that in the case of an outage, failover takes milliseconds
.
Ethernet is specified for latency-sensitive applications such as those involving voice or video.
