我们可以在HL7版本2中使用MLLP第2版吗?

[英]Can we use MLLP release 2 with HL7 version 2?

Documentations found on web says, MLLP V2 (release 2) is a requirement for all Message Transport protocols used to transport HL7 Version 3 content. 网上发现的文档说,MLLP V2(第2版)是用于传输HL7第3版内容的所有消息传输协议的要求。 It seems that MLLP release 2 is used mostly with HL7 version 3 only. 似乎MLLP第2版主要用于HL7版本3。

Can/Should we use MLLP release 2 as transport protocol to transport HL7 version 2 ? 可以/我们应该使用MLLP第2版作为传输HL7版本2的传输协议吗?

Why MLLP V2 is a requirement to transport HL7 version 3 content? 为什么MLLP V2是传输HL7版本3内容的要求?

MLLP release 2 is based on version 1, but goes further by adding defined ack/nak messages, so that the data exchange gets reliable. MLLP版本2基于版本1,但通过添加定义的ack / nak消息进一步发展,以便数据交换变得可靠。 Now the sender knows if the message went thru or he should act eg by sending the message again. 现在发件人知道消息是通过了还是他应该通过再次发送消息来行动。 If you use asynchronous communication in HL7 V3, the sender needs a way to know if the sending was successful. 如果在HL7 V3中使用异步通信,则发送方需要知道发送是否成功。

As long as synchronous communication with the respective acknowledgement messages is used, it is debatable if there is need for the use of MLLP release 2 in HL7 V2. 只要使用与相应确认消息的同步通信,如果需要在HL7 V2中使用MLLP版本2,则存在争议。
