Method and system for host discovery and tracking in a network using associations between hosts and tunnel end points

Abstract:

A system and method for host discovery and tracking in a network. Specifically, the disclosed system and method entail maintaining bindings pertinent to the mapping of any host in the network, by way of their host IP address, to a respective virtual tunnel end point (VTEP). More specifically, these bindings may include: (i) a host IP address to host MAC address binding or mapping; and (ii) a host MAC address to VTEP IP address binding or mapping. Further, these bindings may be especially significant towards directing network traffic to a host over virtual layer-3 (L3) protocols.
