Various example embodiments relate generally to supporting queuing of packets in a communication network. Various example embodiments for supporting queuing of packets in a communication network may be configured to support queueing of packets based on a packet queuing memory space including a hash entry space configured to maintain a set of H hash entries and a packet queue space configured to maintain a set of Q packet queues, wherein H is greater than Q. Various example embodiments for supporting queuing of packets in a communication network may be configured to support queueing of packets in a manner for handling packet events (e.g., packet arrival events, packet departure events, or the like) while preventing or mitigating queue collisions of hash entries (where a queue collision occurs when multiple hash entries, and the respective network flows of those hash entries, are associated with a single packet queue).
