Carrier Ethernet - When, Where, Why?
Nemertes Research, March 2010, Pages: 11
Carrier Ethernet is fast emerging as a credible and effective WAN technology, particularly for a handful of use cases including data-center interconnection, contact-center connectivity, and the interconnection of other sites generating (or receiving) large volumes of traffic. Benefits of Carrier Ethernet include lower cost (measured in price per Mbit/s) and lower complexity in many scenarios. Yet although Carrier Ethernet can be “cheap and cheerful” to deploy, it’s not entirely trivial. Network architects need to consider a number of factors including:
- The type of carrier Ethernet, which can include Layer 2 access to Layer 3 MPLS services, point-to-point Ethernet, and multipoint virtual-private-LAN service (VPLS)
- Quality-of-service (QoS) mechanisms, which can include both layer 3 (DiffServ) and layer 2 (802.1p) options
- Type of customer premises equipment (layer 2 versus layer 3)
Finally, IT practitioners should recognize that deploying Carrier Ethernet isn’t an “either/or” decision—it can coexist seamlessly with other WAN technologies, including MPLS.
