The carrier Ethernet market is growing tremendously, fueled by the growing acceptance of Ethernet as the answer to the industry's bandwidth scalability issues. The disparity between carriers' revenue streams and the amount of bandwidth consumed by each service is causing carriers to seek more cost-effective options to reduce OPEX and CAPEX. Designed from the ground up for this carrier reality, the Extreme Networks BlackDiamond 20800 series switches allow carriers to compete effectively while satisfying their customers' needs and expectations.
BlackDiamond 20800 series switches enable a single carrier Ethernet transport network to deliver residential, business, mobile backhaul, and wholesale Ethernet services. Residential services include triple-play services, IPTV, tiered Internet access, and more. Business services include standard E-Line and E-LAN to connect multiple sites, plus tiered Internet access and VoIP with hierarchical bandwidth controls to individual businesses. Mobile backhaul services deliver the bandwidth needed for multimedia devices running on 3G wireless networks.
The industry's highest port density
With 64 line-rate 10 GbE ports available in a single chassis and 192 per rack, the BlackDiamond 20808 switch offers the highest system capacity in the market both in terms of performance and port count. These high performance switches can deliver more services to more subscribers, resulting in a network with fewer elements that costs less to operate.
Flexible design to meet growing bandwidth needs
Business subscribers are deploying increasingly complex applications to maximize business productivity. On the residential side, the demand for triple-play services and the growth of telecommuting and home-based businesses spur the need for even more bandwidth. Wireless service providers must accommodate growing subscriber bases as well as a surge in voice and data service usage. Global carriers increasingly need the ability to serve their customers with end-to-end services across disparate locations and service areas. The BlackDiamond 20800 switches provide a future-proof design, with 120 Gbps per slot capacity that enables future 100 GbE I/O modules, to support today's bandwidth and service demands as well as future needs.
Advanced multicast scaling
BlackDiamond 20800 series switches deliver outstanding multicast performance with dedicated priority queues to support tens of thousands of multicast streams delivered to corporate recipients or residences simultaneously. Multicast traffic is replicated using multiple references to a packet's memory, which avoids multiple packet copies to provide efficient delivery of financial data or video streams, for example.
Effcient network-to-network interfacesProduct Highlights
End-to-end QoS provisioning is important in providing quality services to business enterprise customers whose workgroups are located across multiple carrier boundaries. Network-to-Network Interfaces (NNI) and Ethernet cross-connect capabilities combined with Hierarchical QoS on the BlackDiamond 20800 series allow provider and application peering, so carriers can extend their service level agreements outside their geographic footprint. Traffic to and from each peer can be controlled on a per-VLAN and per-class-of-service basis. For wireless and wholesaling carriers, an Ethernet NNI also provides a cost-effective Ethernet solution that can significantly reduce bandwidth leasing costs.
