网络设备的数据平面负责处理数据包的传输与处理。开源的向量分组处理器（VPP）作为一种下一代数据平面框架，运行在通用CPU架构上，提供了灵活性、可扩展性以及高速数据包处理和转发性能。然而，VPP的调度模型仅支持运行时循环（RTC）调度执行模式，在该模式下，单个分发执行全图处理无法实现多核CPU间的数据包负载均衡。为解决这一问题，本文引入了流水线调度执行模式及分组分发模型，将VPP的数据包处理图节点映射到多个不同的CPU集合。此外，在数据包处理图的执行过程中，允许对分组进行多次重新分配至不同的CPU核心，从而避免单次分配的不均衡性，实现负载均衡调度。实验结果表明，改进后的VPP能够在数据包处理图的执行过程中进行多次分组分发，实现跨多核CPU的负载均衡。
