Aplication Specific Integrated Circuit.. It's a chip that performs a
certain task in a device..
>From the Cisco website Cat 3900 product info:
The switching-fabric ASIC is responsible for managing the central
shared-data buffer and its associated buffer table, which carries addressing
information for the buffer. The 10 Gbps link between the switching-fabric
ASIC and the shared-data buffer yields a 5 Gbps forwarding rate. The radial
interconnect with network satellites minimizes the number of pins per data
interconnection and distributes available bandwidth among the satellites.
This design both maximizes reliability and lowers cost.
A lot of vendors use ASICs because they perform their task quicker than
software code relying on a central CPU and shared memory.. You could have an
ASIC donig all the VPN encrypting/de-encrypting in a device and remove that
burden from the CPU itself..
Hope that helps
