Congestion is the killer of low latency and high throughput.Network congestion occurs on the interconnection links of a data center due to poor traffic distribution. Load balancing technologies are used to solve network congestion. Packet spraying is a kind of load balancing technology with finer granularity. During this situation, the packets may arrive at the destination out of order. This document describes a reordering protocol in the Geneve encapsulation network[1] using a newly defined Geneve Option field.
