The Juniper IQ2 Physical Interface Card (PIC) family introduces the Ethernet Services Engine (ESE), applying a rich set of hierarchical QoS, fine-grained queuing, and oversubscription capabilities to address the most challenging Ethernet applications faced by service providers and enterprises. Key applications include service aggregation for the multiplay needs of business and residential users, MPLS services at Layers 2 and 3, and the convergence of legacy transport such as ATM and Frame Relay over Ethernet. IQ2 PICs are also ideal for data center applications, connecting broadband applications to the multiservice edge, or linking aggregation nodes to core routers or the Internet. Finally, the Juniper ESE design provides customizable service intelligence through programmable interface processors. IQ2 PICs enhance your service delivery offerings while minimizing TCO.
