APRIL 20, 2009 -- Ciena Corp. (search Lightwave for Ciena) has expanded its Carrier Ethernet Service Delivery (CESD) portfolio, adding new capabilities to its existing CN 5305 Service Aggregation Switch and introducing three new platforms. The new additions, all of which have been fielded and are currently available, continue to leverage the common service-aware operating system and unified Ethernet management software of the existing CESD platforms.
The new platforms enable service providers to quickly and economically expand their addressable market for Carrier Ethernet services by meeting the needs of network locations that require higher bandwidth user connections and a broader set of aggregation and switching capabilities, such as enterprise locations, backhaul from wireless cell sites, multi-tenant unit buildings and outside plant cabinets.
The CESD line includes two main product types. Service Aggregation Switches, as their name implies, provide aggregation functions, while Service Delivery Switches provide service delivery, most commonly at the customer premises. The enhancements open new applications for Ciena's CESD portfolio while offering "right sized" platforms for a wider variety of customer requirements, says Dave Parks, director of product marketing at Ciena. Taken together, the line now supports wire-speed Layer 2 switching, 10 Gigabit Ethernet (10GbE) subscriber ports on a customer premises device, and flexible deployment options, operating in either indoor or unconditioned outdoor environments.
The software upgrades to the CN 5305 Service Aggregation Switch provide optional support for MPLS/H-VPLS for multiprotocol aggregation and switching and simplified IP/MPLS router handoff. The CN 5305 is the only Carrier Ethernet switch to interwork among such formats as Q-in-Q, PBB-TE and MPLS/H-VPLS, Parks asserts.
Meanwhile, the three new CESD Service Delivery Switches include:
- The CN 3960 Service Delivery Switch, designed to deliver cost-effective, high-capacity 10GbE user ports for high-bandwidth business services, wholesale, and wireless backhaul applications. It supports 802.1Q VLANs, Q-in-Q, and PBB-TE, with MPLS/H-VPLS support slated for the second half of this year.
- The CN 3940 Service Delivery Switch, which provides dense Gigabit Ethernet service delivery or aggregation in a 1 RU size. It also supports 802.1Q VLANs, Q-in-Q, and PBB-TE, with MPLS/H-VPLS support available in the second half of the year.
- The CN 5140 Service Aggregation Switch, which can fit into outdoor cabinets and operate over an extended temperature range, offering a compact, ETSI form-factor with front access to all user and network ports as well as power and system interfaces. Again, MPLS/H-VPLS support is scheduled to complement its existing 802.1Q VLAN, Q-in-Q, and PBB-TE support during the latter half of this year.
