Network Layer - Milin of the control communication between the data link layer and the network layer is the establishment of a maximum size for the packet. The data link layer passes the MTU value up to the network layer. The network layer then determines how large packets should be. MTU and MSS: Internet terms explained Jan 03, 2017
How does the network layer use the MTU value? The MTU is passed to the network layer by the data link layer A router may have to fragment a packet when forwarding it from one medium to another medium that has a smaller
In addition. MSS value derives from the value MTU, if you have a 800-byte packet, it can also say that such a packet was originally 2260 bytes long, and he broke into 2 packet 1460 + 800 bytes, if we use MTU = 1500. You say is true, if you MSS = 800, the MTU should be at least 840. As PPPoE overhead is 8 bytes, and therefore MTU = 1492 bytes, and MSS = 1492-40 = 1452 bytes. Slow Network Access Due to a Large TCP MSS Value- Huawei The network devices have different MTUs. The maximum size of packets that can be transmitted through the link is determined by the minimum MTU among the MTUs of the network devices. The protocol specific to a layer higher than the network layer does not concern about the MTU of each device on a traffic transmission path.
Why the MTU size is 1500 ? - Cisco Community
MTUs can be measured either at the network layer or at the link layer. For example, the standard Ethernet MTU is 1500 bytes at the network layer but 1518 bytes at the link layer. The values given here are network-layer MTUs unless stated otherwise, but be aware that equipment manufacturers often specify link-layer MTUs instead. Debugging MTU Problems - Energy Sciences Network A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network such as the Internet. The Internet's Transmission Control Protocol (TCP) uses the MTU to determine the maximum size of each packet in any transmission.
