A Router in Swarm DB handles compute queries that required certain amount of complexity and query planning. For simple queries with Beeson Query Language, that won't require extensive reference lookups or transform, a direct query planning estimation is enough and does not require a router.
For any other type of transaction or execution, like eg data / index jobs or work orders, availability and query planning will be required to query a router.
Guide-level explanation
Defining a registry of compute node
As specified in Swarm DB - Compute Node, a node takes care of data computations that takes certain amount of resources and complexity. Each compute node must register in a smart contract registry and be assigned an ENS name. Using EIP-3668, a off-chain call is made with a polling mechanism to get the liveness and compute cycles of the node (WASM) engine. A node also needs to implement EIP-5559: Cross Chain Write Deferral Protocol to accept storage tasks
