E-NNI is an Ethernet Network to Network Interface. Network interfacing is the cross-connection that allows different networks to exchange traffic. Each has to advertise the other’s routes so that users on either network can reach destinations on the other network as easily as they do on their own network. The result is an interconnected network with a service footprint the size of both networks combined.
An excellent example of an Ethernet to Ethernet network connection is taking place in the Phoenix, Arizona metropolitan area. Integra Telecom and Saddleback Communications are connecting their fiber networks using enterprise-class Carrier Ethernet technology so that they can easily exchange data at high transmission rates.
Saddleback Communications is an Incumbent Local Exchange Carrier (ILEC) serving the Salt River Pima-Maricopa Indian Community (SRPMIC) in the Phoenix metropolitan area, bordered by Scottsdale, Mesa, Tempe and Fountain Hills. Their core network infrastructure is comprised of multiple fiber optic rings and two Class 5 Soft Switch Central Offices. Unlike most commercial areas, 100% of the commercial developments on the Pima corridor of the SRPMIC are fed with both fiber optic and copper facility connections.
Saddleback’s business services include dedicated Ethernet Internet access, Ethernet transport services and private line services. Their BusinessLAN Ethernet Transport transparently connects business locations via native Ethernet at speeds from 5 Mbps to 1000 Mbps (GigE) with scalability in 5 Mbps or 100 Mbps over the same interface.
What Integra Telecom brings to the table is an extensive fiber optic network that serves 11 Western states, including Arizona, California, Colorado, Idaho, Minnesota, Montana, Nevada, North Dakota, Oregon, Utah and Washington. Their 5,000 mile long haul network is one of the largest in the U.S., complemented by a 3,000 route mile (160,000 fiber miles) metropolitan area network that serves 200 business communities including 1,700 fiber-fed buildings. Integra is the 4th largest Competitive Local Exchange Carrier (CLEC) in the United States.
Integra offers Metro Ethernet Forum (MEF) standardized Ethernet services that include Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL), as well as a layer 2 configuration for high performance Wide Area Networks (WANs). Class of Service (CoS) technology makes voice/data/video converged networks possible so that sensitive real time packets aren’t overwhelmed by less critical but more numerous data packets.
Both Saddleback and Integra operate high performance fiber optic networks and both serve a wide range of customers, including corporate clients that need highly reliable high bandwidth Ethernet services. By interconnecting their networks for Ethernet to Ethernet transport, they can offer companies on both networks the opportunity to connect as if they are working under a common “digital roof.”
