Silver Peak Systems is introducing a 1Gbit/s version of its WAN optimisation box.
The NX-9000 has two 10Gbbit/s physical WAN ports that each support 1Gbit/s optimised throughput and four 1Gbit/s ports that serve as LAN connections. The device supports more than 250,000 simultaneous TCP flows, as well as disk encryption and wire-speed encryption of traffic flowing across the network.
Part of the optimisation includes local caching of traffic patterns that have already crossed the WAN so shorter markers representing those patterns can be sent instead, reducing total WAN traffic. The device includes an 8TB hard drive to store the cached patterns.
Competitor Riverbed's WAN optimisation gear tops out at 800Mbit/s for a single box, and can be clustered for a total speed of 4Gbit/s, the company says.
Cisco says its WAN optimisation WAE 7371 gear has a throughput of 1Gbit/s.
