Ethernet in the WAN gets a boost with new solutions for the enterprise
Nokia Siemens Networks A-series 2200 carrier switch meets growing bandwidth demand
The A-series 2200 brings the necessary horsepower to the network to fuel demanding business applications, handles voice and data, and also offers high levels of reliability, scalability and security.
Today 99 percent of Local Area Networks are using the Ethernet protocol, which was originally developed as a means of connecting computers, printers, servers and peripheral devices within buildings and campus networks.
Increasingly, however, forward-thinking enterprises are extending Ethernet-collapse backbone LANs across Metropolitan Area Network (MAN) and Wide Area Networks (WAN s) in a seamless, cost effective fashion while maintaining native LAN speeds. As a result, the demand for Ethernet services is booming. Much of its popularity is driven by migration from legacy TDM or IPVPN technology from businesses looking to roll out increasingly bandwidth hungry applications.
Nokia Siemens Networks has developed solutions that help carrier meet enterprise customer needs. The A-series 2200 provides an effective bridge between an existing TDM network and the next generation Ethernet transport network for enterprises. It brings many benefits: it combines the best of SDH carrier-class security and robust data transport capabilities. Additionally, it enables greater cost efficiencies, as a single hardware device can carry both voice and data traffic, and the architecture enables greater traffic at lower costs.
"The new A-series 2200 is certainly the Rolls-Royce amongst the Carrier Ethernet switches - the ideal platform to provide Ethernet services like Colt offers them Europe-wide. Together with our awarded management software Aspen it is unmatched solution", says Eli Erlich, Product Line Manager Carrier Ethernet at Nokia Siemens Networks.
With a maximum switching capacity of 24 Gigabit per second, the A-series 2200 provides the power to handle even most demanding applications such as voice, video or Storage Area Networks.
The solution is true carrier-class. It comes with redundant power supplies and fans and offers resilience & survivability mechanisms to ensure smooth service provisioning. It offers carrier-grade Service Level Agreement (SLA) with 50 milliseconds protection with Committed Information Rate (CIR) and it is a scalable solution to more than 5000 network elements.
The solution can serve as an edge solution located at the customer premises or as an aggregation unit that gathers traffic from different customer networks. Due to its modular structure A-series 2200 is very flexible. It is also suitable for mobile backhaul applications.
A carrier can easily add a TDM or Ethernet service card as required, or use a Combo Card to enable both capabilities simultaneously.
The Pan-European carrier COLT has recently decided to base its Ethernet services on the A-series solution from Nokia Siemens Networks:
The Carrier Ethernet-based MSP offers customers better performance by delivering high bandwidth services with lower latency, lower jitter and improved resilience.
Those attributes are indispensable for business customers and distributed data centers. The technology - supplied by Nokia Siemens Networks - uses a single box capable of delivering up to 16 services at speeds of up to 1Gbit/s. This saves space and power at customer premises as well as providing the means for additional services or upgrades to be delivered without the need for hardware changes.
COLT's MSP will deliver secure Ethernet Services by using Layer 2 MPLS technology to logically separate Ethernet services from IP traffic and provide the customer with dedicated bandwidth for Ethernet services. The Carrier Ethernet transport solution and services are centrally managed and monitored, allowing COLT to simplify the delivery and management of end-to-end Ethernet services to its customers.
