rte_ipv4_hdr是DPDK(Data Plane Development Kit)网络开发框架中定义的结构体,用于表示IPv4报文头部信息。其定义通常如下: structrte_ipv4_hdr{ uint8_tversion_ihl;// 版本号和首部长度 uint8_ttype_of_service;// 服务类型 uint16_ttotal_length;// 报文总长
* IPv4 Header*/structrte_ipv4_hdr { uint8_t version_ihl;/**< version and header length*/uint8_t type_of_service;/**< type of service*/rte_be16_t total_length;/**< length of packet*/rte_be16_t packet_id;/**< packet ID*/rte_be16_t fragment_offset;/**< fragmentation offset...

length是原始数据部分的长度,sizeof()函数用于获取结构体rte_ether_hdr、rte_ipv4_hdr和rte_udp_hdr的大小(以字节为单位),然后将它们累加到length上得到最终的总长度。 struct rte_mbuf *mbuf = rte_pktmbuf_alloc(mbuf_pool);这一行使用 DPDK 提供的函数rte_pktmbuf_alloc()从指定的内存池中分配一个 RTE ...

这部分最多包含40字节,因为TCP头部最长是60字节(其中还包含前面讨论的20字节的固定部分)。4位头部长度(header length):标识该TCP头部有多少个32bit字(4字节)。因为4位最大能标识15,所以TCP头部最长是60字节。intipv4_hdrlen = (iph->version_ihl & RTE_IPV4_HDR_IHL_MASK) <<2;...
