switchingrouting
Switching and routing are fundamental functions in computer networking. Switching forwards frames within a single broadcast domain, while routing determines how packets reach other networks. The term switchingrouting describes an integrated approach in which network devices perform both Layer 2 switching and Layer 3 routing to forward traffic efficiently. In practice, this is most commonly implemented in multilayer switches that combine a fast switching fabric with a routing engine, enabling rapid intra-network delivery and inter-network path selection within a single device.
In traditional networks, switches handle Layer 2 forwarding and create local networks, while routers handle Layer
Key concepts include the interaction of MAC addresses and IP routing tables, VLANs for segmenting broadcast
Trends in switchingrouting include the use of software-defined networking (SDN) to separate control and data planes,
