协议术语：消息与数据包
在实践中，对于采用更高级别协议（例如 TCP/IP 之上的协议）通过网络传输的通信最合适的术语是什么？ 具体来说，我指的是小的二进制数据单元。
我在各种客户端/服务器库中都看到过“消息”和“数据包”，但我对社区的共识感兴趣。
In practice, what is the most appropriate term for the communications transmitted over a network in higher level protocols (those above TCP/IP, for example)? Specifically, I am referring to small, binary units of data.
I have seen both "message" and "packet" referred to in various client/server libraries, but I was interested in the community's consensus.

这些绝对是消息。 “数据包”是第 3 层（ISO 术语）协议单元，例如 IP 数据包； “数据报”是第 1 层或第 2 层单元，例如可能组成 IP 数据包片段的多个以太网数据报。
因此，一条消息可能会被拆分为多个数据包，特别是当您使用 TCP 等流协议时，并且一个数据包可能会被拆分为多个数据报。
These are definitely messages. A "packet" is a layer-3 (in ISO terminology) protocol unit, such as an IP packet; and a "datagram" is a layer-1 or layer-2 unit, such as the several Ethernet datagrams that might make up the fragments of an IP packet.
So a message might be split across several packets, particularly if you're using a streaming protocol such as TCP, and a packet might be split across several datagrams.
只是我的看法。 这可能取决于您的工作级别。 当我想到整个传输（所有标头、数据等）时，我将其称为消息。 数据包（尤其是 TCP/IP 中的数据包）只是消息的一部分。 多个数据包通过网络推送，构成完整的消息。
Just my take. It probably depends on what level you are working at. When I think of the entire transmission (all headers, data, etc) I would call that a Message. A packet, especially in TCP/IP, is just a part of a message. Multiple packets are pushed across the network comprising an entire message.
我认为数据包是指在以太网等较低层上传输的数据块，而消息用于高层信息交换。
在我看来，它们基本上意味着相同...
编辑：
还有另一个称为帧的术语，它在 RFC 1122 中定义为“链路层协议中的传输单元，由链路层标头和后面的数据包组成”。 [维基百科]
I think packet refers to the chunks of data transferred on a lower layer like Ethernet and message is used for higher level information exchange.
imo they basically mean the same...
edit:
There's also another terminology called frame, which is defined in RFC 1122 as "the unit of transmission in a link layer protocol, and consists of a link-layer header followed by a packet." [wikipedia]
msgs 是网络层中的数据包
它是 TCP 协议（传输层）中的分段
它是 HTTP 或 FTP（应用层）中的 msgs
msgs is packet in Network Layer
it is segement in TCP protocol(Transmission Layer)
it is msgs in HTTP or FTP(Application Layer)
