Per-flow load balancingensures that packets within the same flow are always forwarded over the same path, ensuring that packet order is preserved.
Step-by-Step Breakdown:
* Flow Definition:A flow is typically defined by a combination of packet attributes like source
/destination IP, source/destination port, and protocol type. Packets that belong to the same flow are routed over the same path to avoid reordering.
* Per-Flow Behavior:Inper-flow load balancing, the hashing algorithm ensures that all packets in a particular flow use thesame egress port, maintaining order across the network.
Juniper Reference:
* Load Balancing in Juniper: This method ensures that flows are balanced across multiple paths while preventing packet reordering within a single flow.
