Dune Networks has begun sampling a new member in its PETRA family that integrates complete 80Gbps full-duplex line card functionality into a single device addressing Data Center and Carrier Access requirements. The solution is aimed at high-density switching line cards ranging from 24 to 48 10GE ports. Such line cards could enable a switching system design featuring a non-blocking fabric, 100ms packet buffer and densities of up to 768 ports of 10GE or 40GE/100GE equivalent with a single stage fabric.
The P330 incorporates a flexible packet processor using micro-code engines. Packet-processing features include L2 bridging, L3 IPv4 and IPv6 unicast and multicast routing, flexible L2/L3/L4 aware ACLs. For Data Centers, the P330 offers additional benefits such as enhanced TCP performance, TCP starvation avoidance, Lossless Ethernet support, high fan-out ECMPs and LAGs, security and policing, and virtualization support.
