One major development in WANS has been the development of hardware accelerators for the WAN. Such systems, which work at the Layer 2 level, allow for much more throughput than the standard for TCP/IP, but are, of course, proprietary. You should research, using whatever tools you care to employ, the concept of WAN hardware acceleration, and find at least one example of such a tool. Post your initial comment on this topic, being sure to cover the following points:

• The manufacturer of the WAN accelerator along with the Web site.

• The range of devices offered by the manufacturer, their prices, and capabilities.

• Indication of what improvement in throughput this WAN accelerator provides. An explanation of how the accelerator implements improvement in Layer 2 framing to accomplish its tasks.
