Abstract
Systems and techniques for processing and forwarding packets are described. During operation, a system can receive a packet on an input port. Next, the system can identify a set of bits in the packet that represents a route from a source node to a destination node in an n-ary tree. The system can then determine an output port based on a subset of the set of bits. Next, the system can determine whether the output port is free. If the output port is not free, the system can use a contention resolution mechanism to store the packet in an on-chip memory or an off-chip memory based on space availability and the packet's priority. If the output port is free, the system can send the packet through the output port.
