  Hardware Switching is performed by ASICs and Software Switching is performed by CPUs.
  The term hardware-switching refers to the act of processing packets at any Layers 2 through 7, via specialized hardware components referred to as ASICs. ASICs can generally reach throughput at wire speed without performance degradation for advanced features such as QoS marking, ACL processing, or IP rewriting.
  Other terms used to describe hardware-switching are in-hardware, using ASICs, and hardware-based.
  Multilayer switching (MLS) is another term commonly used to describe hardware-switching. MLS describes the capability to route and switch frames at line-rate (the speed of all ports sending traffic at the same time, full-duplex, at the maximum speed of the interface) with advanced features such as Network Address Translation (NAT), QoS, access controls, and so on using ASICs.
  Switching and routing traffic via hardware-switching is considerably faster than the traditional software-switching of frames via a CPU. Many ASICs, especially ASICs for Layer 3 routing, use specialized memory referred to as ternary content addressable memory (TCAM) along with packet-matching algorithms to achieve high performance, whereas CPUs simply use higher processing rates to achieve greater degrees of performance. Generally, ASICs can achieve higher performance and availability than CPUs.
