In Which Layers Are the Mss and Mtu Used
However this does not prevent IP fragmentation since there can be paths with PMTU lower than 1500 eg. Is MSS same as MTU. What Is The Difference Between Mss And Mtu In Computer Networking Quora This is in byte MSS is your MTU minus layer 3 and 4 thus if we imagine 20 Byte for IP. . Frame PDU of the Link Layer IP Datagram Unfragmented PDU of the Network Layer before fragementation or after reassembly IP IPv4 - Internet Protocol Version 4 IPv6 Internet Protocol Version 6 MTU Maximum Transmission Unit Maximum Transmission Unit Defines the limit of bytes which can be transmitted at this link Packet PDU of the Network Layer. The MTU is the Maximum IP packet size for a given link. I have also seen it as 1518 where does the 18 come from. MTU and MSS sizes. This process is called fragmentation and it is done by the Network layer. Unlike MTU packet greater than MSS arent fragmented theyre simply just discarded. MTU...
