Abstract
A computer-implemented method for repurposing one or more software configurable layer 2 switches in an IP (Internet Protocal) computer network to function as a layer 1 switch. Ternary Content-Addressable Memory (TCAM) is reconfigured in each of the one or more layer 2 switches and one or more pipeline engines are routed to emulate layer 1 switching functionality in each of the one or more layer 2 switches.

A computer-implemented method for repurposing one or more software configurable layer 2 switches in an IP (Internet Protocol) computer network to function as a layer 1 switch comprising:
- reconfiguring Ternary Content-Addressable Memory (TCAM) in each of the one or more layer 2 switches;
- routing one or more pipeline engines to emulate layer 1 switching functionality in each of the one or more layer 2 switches;
- disabling forwarding functionality to decrease latency in each of the one or more layer 2 switches;
- enabling Small Form-Factor Pluggable Ports (SFPs) for Transmission (TX) and Reception (RX) in each of the one or more layer 2 switches;
- creating a multicast group such that a Port.2 is added to the created multicast group in each of the one or more layer 2 switches;
- and
- providing an Access Control List (ACL) rule wherein when a condition is input Port.1 an action is to redirect to the created multicast group in each of the one or more layer 2 switches.
