Stake-Weighted Quality of Service
SWQoS is packet admission before execution.
SWQoS is a Solana networking feature for leader TPU traffic. With configured validator/RPC peers, a stake-weighted share of inbound packets can receive priority during congestion. It runs before priority-fee handling and before the normal transaction execution path.
质押加权优先级 (SWQoS)
SWQoS 按质押权重分配 leader 的 TPU 准入。
Solana leader 可以为与质押关联的连接，按质押权重预留一部分 TPU 容量。其他流量使用剩余容量。
这发生在 priority fee 处理和运行时执行之前，因此它决定的是拥塞期间哪些数据包能进入 leader 路径。
对运营者而言，SWQoS 取决于已配置的 validator/RPC 对等关系以及该路径背后的质押权重。

leader TPU 容量如何划分
质押加权流量可在费用处理之前使用预留的 TPU 份额;其他流量共享剩余容量。
目前的 Solana 指南描述了 80 / 20 的 leader TPU 分配。
