Functions ¶
func BuildFromFile ¶
func BuildFromFile(pcapPath, clientEp, serverEp string, includeZeroLen bool) (*replayplan.Plan, error)
BuildFromFile 读取 PCAP / PCAPNG 路径并生成 plan（文件可 Seek：NG 失败时回绕重试）。 clientEp / serverEp 可为 IPv4、IPv4:PORT 或 IPv4:0；端口省略或为 0 时该侧匹配任意端口。 includeZeroLen 为 true 时保留 TCP/UDP payload 长度为 0 的包。
func BuildFromFileWithAutoEndpoints ¶
func BuildFromFileWithAutoEndpoints(pcapPath string, includeZeroLen bool, clientIPPrefix string) (*replayplan.Plan, net.IP, net.IP, int64, error)
BuildFromFileWithAutoEndpoints 打开 PCAP/PCAPNG，先按最大流推断客户端/服务端 IP，再生成 plan（端口侧为 0，与仅写 IP 的 endpoint 一致）。 返回值 flowPayloadBytes 为该流上累计的 TCP/UDP 应用层 payload 字节（与 aggregate 口径一致）。
func BuildFromReader ¶
func BuildFromReader(r io.Reader, clientEp, serverEp string, includeZeroLen bool) (*replayplan.Plan, error)
BuildFromReader 从经典 **PCAP** 流生成 plan（不支持 pcapng；若需 NG 请用 BuildFromFile）。
func GuessClientServerFromFile ¶
func GuessClientServerFromFile(pcapPath string, includeZeroLen bool, clientIPPrefix string) (client net.IP, server net.IP, flowBytes int64, err error)
GuessClientServerFromFile 按 **IPv4 TCP/UDP 应用层 payload 总字节** 最大的无向流，推断客户端与服务端 IP。 includeZeroLen 与 BuildFromFile 一致：为 false 时长度为 0 的包不参与统计。 clientIPPrefix 非空时，匹配该前缀（CIDR 或点分前缀，见 parseClientPrefix）的一侧为客户端；两侧同时匹配或均不匹配则报错。 clientIPPrefix 为空时：优先 RFC1918 私网为客户端；否则较低知名端口（<=1024）一侧为服务端；仍无法区分则 **IP 字典序较小** 一侧为服务端。
