What does end-to-end mean?

End-to-end refers to "network connection". In order for the network to communicate, a connection must be established. No matter how far away it is or how many machines are in the middle, a connection must be established between the two ends. Once the connection is established, it is said to be an end-to-end connection, that is, the end-to-end is a logical link.

End-to-end is a network connection.

In order for the network to communicate, a connection must be established. No matter how far away it is or how many machines are in the middle, a connection must be established between the two ends (source and destination). Once the connection is established, it is said to be the end. It is connected end-to-end, that is, it is a logical link end-to-end. This path may go through a very complex physical route, but the hosts at both ends do not care and only think that there is a connection at both ends, and once the communication is completed, the connection is released. , the physical line may be used by other applications to establish connections. TCP is a specific protocol used to establish this end-to-end connection, as is SPX.

The position of end-to-end in OSI

End-to-end is the transport layer. For example, if you want to transmit data from A to E, there may be After going through A→B→C→D→E, the transport layer does not know the existence of b, c, and d. It only thinks that my message data is directly from a to e. This is called end-to-end. .

In short, the summary in one sentence is that end-to-end is implemented and composed of countless point-to-point.

End-to-end process

"End" refers to the input or output points outside the enterprise. These external output or input points include customers, markets, external governments or institutions and business stakeholders.

"End-to-end process" refers to a series of coherent and orderly combinations of activities with customers, markets, external governments or institutions, and corporate stakeholders as input or output points.

The end-to-end process starts from the customer demand end and ends at the customer demand end, providing end-to-end services. The input end of the end-to-end is the market, and the output end is also the market. This end-to-end must be very fast and efficient, with no reservoirs or Three Gorges in the middle, and the process must be smooth. If such fast service is achieved, labor costs, financial costs, and management costs will be reduced, which means operating costs will be reduced. In fact, end-to-end reform is to reform the simplest and most scientific internal management system to form the most streamlined team.

The end-to-end process connects not just two adjacent departments, but several departments, which is the entire closed loop of a certain business. This end-to-end process starts from analyzing customer needs and ends with collecting customer feedback. It goes through several stages such as concept formation, market research, application development, product implementation, market testing, sales promotion, and performance evaluation. It involves the marketing department, R&D department, purchasing department, production department and several other departments. Moreover, this end-to-end process actually includes partial processes such as marketing process and purchasing process.

Domestic companies with relatively high level of process management have developed end-to-end processes, such as Huawei’s Integrated Product Development (IPD) process, Integrated Supply Chain (ISC) process, Shanghai Bell-Alcatel’s “from order tocash” processes, these processes are different from the detailed processes within enterprise departments or between adjacent departments.
