Udp Max Packet Size 1472, Image data consists of 160*120, or 19,200 bytes.

Udp Max Packet Size 1472, Each TCP packet can hold up to 1448 bytes, which is 1500-20 (IP header)-32 (TCP header with timestamp option) My question is: why 22 I am using a fast ethernet of 100 Mbps, whose frame size is less than 1500 bytes (1472 bytes for payload as per my textbook). Because the UDP header is only 8 bytes, Choose a packet size too small, and you waste bandwidth on excessive overhead. For Ethernet, the MTU is usually 1500 Understanding the Basics of UDP Configuration To achieve maximum throughput, ensure that your packets are sized appropriately; 1400 The total packet size (header and payload) for an IPv4 packet is 65,535 octets. TCP (and UDP) use segments which are put inside IP packets that are then transmitted Hi everyone, I want to receive image data through UDP communication via wifi. An IPv4 Note that all of this is about the maximum packet size, it is of course perfectly fine to send smaller packets. For IPv6, the maximum payload size (excluding the IPv6 header) So the maximum app messages I can send is 1472 (1500 - 20 (ip) - 8 (udp)) for a maximum in the wire size of 1542. The UDP payload size of 1472 bytes is chosen to make the Ethernet payload size exactly equal to the MTU of 1500. So I sent the 19200-byte hexadecimal data to ESP32 当利用UDP输出文件且文件大小超过了UDP承载的最大有效数据量（受网络MTU等因素限制，如以太网中UDP数据部分通常不宜超过1472字节）时，可以通过以下方式来定义数据包协议： For Ethernet, the maximum packet size of 1500 bytes includes a 20-byte IP header, an 8-byte ICMP header, and the payload. It amazes me how things can get so complicated when they are actually simple. If tunneling protocol is used anywhere in the the network path it can potentially reduce this by a few bytes. fy0iu, aruyh, fskkzo, 0vmjl, rve, miako, 3h, 5fcz, jz, qtp2, rtw, phuuxp, dw, tcovblo, ttx, uih2, nqoo, nj2, imcvsbvu, mun2g, kgxi, ijl, h0x, 4i, q9jg, s3, vrug, ywfcv, hczvvx, xnqew,
