Ciena has expanded its carrier Ethernet service delivery (CESD) portfolio with multiple new service delivery and aggregation switches that leverage a common service-aware operating system and unified Ethernet management software.
The new platforms addreses the need of network locations for higher bandwidth user connections and a broader set of aggregation and switching capabilities.
Ciena\'s newest CESD platforms offer wire-speed Layer 2 switching, 10 Gigabit Ethernet subscriber ports on a customer premises device, and flexible deployment options as they operate in either indoor or unconditioned outdoor environments.
Also, software upgrades to the CN 5305 service aggregation switch make it the only carrier Ethernet switch to seamlessly interwork between disparate encapsulation formats such as Q-in-Q, PBB-TE and MPLS/H-VPLS.
