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. How do you program routers and networking hardware to consume semantics?

As a result, Internet devices usually use a single path and let the routers handle the path selection. Aggregation : MPTCP can aggregate the bandwidth of many network interfaces. MPTCP, by being able to launch many subflows, can expose greater overall bandwidth. Only for low-bandwidth flows. There is another way.

Yes, there’s something to say about how applications are written, but on the public internet side, we’ve seen a decrease in latency, cost, and a massive increase in available bandwidth. We still need to connect our infrastructure to the public internet, so the enterprise WAN is still about routers, circuit IDs, and perimeter firewalls.

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. This enables quicker and more efficient routing, as the router only needs to view a packet label, instead of looking up the address destination in complex routing tables.
