Direct Routing

This example demonstrates a direct per-hop routing implementation in a time-sliced optical network. The per-hop routing approach configures each switch node to make independent forwarding decisions based on the destination address, enabling packets to traverse the network hop-by-hop until they reach their final destination. This method provides a straightforward routing mechanism where each intermediate node determines the next hop based on local routing information.
