Vitesse Unleashes its Jaguar Carrier Ethernet Chips

Vitesse Semiconductor introduced its "Jaguar" family of Ethernet devices designed specifically for Carrier Ethernet. Vitesse's new architecture offers an optimized feature set for transitioning TDM circuit-switched networks to Ethernet. networks. Specifically, the Jaguar family implements service features such as full IEEE-1588 functionality and OAM (Operations, Administration, and Maintenance).


Ethernet timing support for mobile backhaul is delivered with Synchronous Ethernet and IEEE-1588v2.


Vitesse said its service-aware architecture can map client traffic to any of the thousands of services, with each individual service offering Metro Ethernet Forum (MEF)-compliant policing, scheduling, and traffic shaping. A single chip provides thousands of policers and as many as 50,000 statistics to ensure and monitor Service Level Agreements. This results in unprecedented flexible service differentiation and support, allowing providers to easily deploy services such as E-Line, E-Tree, and E-LAN.


The Jaguar family launches with four devices -- two Carrier Ethernet switches: Jaguar (VSC7460) and LynX (VSC7462) and two Media Access Controllers (MACs): CE-MaX-24 (VSC7364) and CE-MaX-12 (VSC7366).


To deliver carrier-grade reliability, these devices afford hardware-generated continuity checking for Port, Link, Tunnel, and Service protection. The fast link failure detection and exclusive path protection mechanism provide reliable 50mS protection switching performance critical to carrier networks.


The Jaguar switches integrate multiple ports of Gigabit Ethernet with advanced traffic-shaping features for service-aware networks.


In addition, Vitesse's Jaguar and LynX switches support all popular connection-oriented and connectionless network protocols, including Provider Bridging, Provider Backbone Bridging (PBB), Provider Backbone Bridging with Traffic Engineering (PBB-TE), and Multi-Protocol Label Switching -- Transport Profile (MPLS-TP). Offering a dense alternative for constrained rack space, the Jaguar has 24 10/100/1000 Mbps Ethernet ports and four 10 Gigabit Ethernet XAUI ports. The LynX is a 12-port version with dual 10 Gigabit ports and the XAUI ports can be configured as four 2.5 Gbps interfaces.


The Vitesse Carrier Ethernet MACs are pin compatible with its switch devices. The MACs are available with two port counts: 24 Gigabit Ethernet ports with four 10 Gigabit ports or 12 Gigabit Ethernet ports with two 10 Gigabit ports. These MACs boast all the service-aware and traffic engineering features of Jaguar and LynX, yet are intended for delivering Ethernet services over SONET and packet optical networks.


Vitesse also plans to announce another family of Ethernet switch products specifically designed for carrier access applications such as mobile backhaul. These carrier access switches share the same software API as the Jaguar family.
