2024年9月2日 · What is the relationship between MSS and MTU? The MTU sets the maximum size of a data frame that can be transmitted over a network interface. The MSS is the maximum size of a data segment that can be transmitted within a TCP connection. The MSS must be less than or equal to the MTU to avoid fragmentation. How does MTU affect network performance?

MSS, or maximum segment size, is the largest data payload that a device accepts from a network connection. Learn about MTU and MSS, and how MSS relates to TCP.

最大分段大小 （M aximum S egment S ize）是 传输控制协议 的一个参数，以 字节 数定义一个计算机或通信设备所能接受的分段的最大数据量。 它并不会计算 TCP 或 IP 协议头的大小。 [1]。 即 最大傳輸單元 除去 信頭 後的最大數據量。 含有 TCP 分段的 IP 資料包 可以在一个数据包内自我包含，也可以从多个 IP分片 中重建。 无论如何，MSS 限制都对最终重建的分段起效。 默认的 TCP 最大分段大小是 536。 [2] 当一个主机想要把 MSS 设置到一个非默认的值时，MSS 大小会以 …

The maximum segment size (MSS) is a parameter of the Options field of the TCP header that specifies the largest amount of data, specified in bytes, that a computer or communications device can receive in a single TCP segment.

2017年11月3日 · TCP 設定封包所帶的資料上限稱為 maximum segment size (MSS)，理論上我們希望它愈大愈好。 以下記錄和 MSS 相關的知識， 懶得看的話只要記住一個結論: OS 都處理好了，沒事不要手癢亂改 MSS 的值。 在討論 MSS 之前，先看 IP layer 的情況。 router 之間傳輸封包大小的上限稱為 MTU。 當 router 發現封包大小超出下一站...

2023年12月12日 · Maximum TCP Segment Size, or MSS, employs three-way handshaking to meet all the requirements of fundamental networking protocols. The maximum transmission unit, or MTU, determines a host computer's capacity to send and receive big data blocks and files simultaneously at a specific time over a computer network.

MSS is Maximum TCP segment Size. Unlike MTU, packet exceeding MSS aren't fragmented, they're simply discarded. MSS is normally decided in the TCP three-way handshake, but some setup might yield path where the decided upon MSS is still too big, leading to dropped packets.

2024年2月23日 · In the establishment of a TCP connection, Maximum Segment Size (MSS) is vital. MSS refers to a field in the TCP header, that denotes the largest amount of data, in Bytes, that the device can receive in TCP segment.

2022年2月10日 · MSS and MTU are two types of important factors and aspects in computer networking that determine the size of each data packet or block to transmission service so that it can be transferred over the computer network as a complete single unit without any breakage. MSS stands for Maximum TCP Segment Si

Two critical concepts often encountered are the Maximum Segment Size (MSS) and the Maximum Transmission Unit (MTU). While these terms may appear interchangeable, they serve distinct purposes in data communication. Understanding their roles and differences is crucial for optimizing network performance.
