SAP NetWeaver Network Protocol --> DPTM ???

[Former Member]

Hello everyone!

I want to analyze the network layer between SAP GUI an SAP NetWeaver host server. Within the SAP MMC of my host I found out that the protocol for communication between SAP GUI and dispatcher is called "DPTM" (as a special part of TCP/IP I guess). Please have a look at my attachment for further details.

As me and my colleagues never heard of this protocol type before, I tried Google search and SAP Notes - unfortunately with no success.

Does anybody of you know this protocol? Where I can find documentation or something about it?

I would be pleased if anyone could help me.

Thanks and best regards,

Michael

PS: I am running SAP NetWeaver AS ABAP 7.31 on Windows 2008 R2

Hi Michael,

In term of Network layer - SAP uses it's NI on top of TCP/IP and this should be some internal protocol of NI which is used by kernel program for client-server communication.

Honestly, not sure on this. Just what I think it should be.

Hi Divyanshu,

thanks a lot for that information. So NI is on OSI-Level 4 and DPTM is probably an a higher level... or do you mean that it is also on level 4 on top of NI?

I am a little bit confused about the fact that there is no official SAP documentation about this protocol type.

Best regards,

Michael
