Linux多路径multipath通过组合多个物理连接提升存储弹性与性能。本文分析路径故障处理流程,包括内核超时检测、用户态iscsid关闭连接、multipathd检测异常路径并触发fail_path,内核选择新路径下发IO,涉及关键源码如iscsi_check_transport_timeouts、fail_pat...
While some networking functionality is placed in user space (e.g., route daemons), it is typically limited to slow-path and control plane processing. In contract, advanced packet processing functions require modification in the operating system kernel. These functions can be introduced either by ...
