Today's Heavy Networking is a forward-looking episode about semantic networking. Semantic networking aims to make decisions on how to route packets based on more than just the destination address and give network operators more routing choices based on considerations such as bandwidth, cost, performance, application type, and so on.

However, global changes like remote work, mobile connectivity and cloud-based infrastructure require businesses to reconsider their MPLS network strategy. MPLS (Multiprotocol Label Switching) is a network routing technique that is based on predetermined paths, instead of routers determining the next hop in real-time.
