destination. Packets inspected at the Layer 3 level are analyzed and
forwarding decisions, based on their applications.
LLDP-MED
Link Layer Discovery Protocol - Media Endpoint Discovery. LLDP allows
network managers to troubleshoot and enhance network management by
discovering and maintaining network topologies over multi-vendor
environments. MED increases network flexibility by allowing different IP
systems to co-exist on a single network LLDP.
Load Balancing
Enables the even distribution of data or processing packets across available
network resources. For example, load balancing may distribute the incoming
packets evenly to all servers, or redirect the packets to the next available
server.
