xRoute vs xDima

[Gr_994]

Hi,

We are using xServer on-premise.

We are using xRoute 1 to create a distance matrix (we don't have installed xDima 1). We are managing to create matrices about 100x100 and even bigger.

After some research, I found out that xDima is mainly used for creating distance matrices.

I was wondering, what is the main difference in the case of creating a distance matrix with xRoute and xDima in xServer 1? If more differences exist in the case of xServer 2, I would like to hear about it.

Also, we are testing the functionality of xServer 2, and I didn't see in Raw Request Runner the possibility of creating a Distance Matrix with xRoute, just with xDima. Can a distance matrix be created with xRoute 2?

Thank you.

Best regards,

[Joost]

Main difference is the size of the dima. xRoute does not support large dima's. The limit is iirc 750 x 750 for xRoute.

In xServer 2 xRoute no longer has a matrix call. We decided that maintain dima functions on 2 locations is not usefull. Instead we did support easy dima access for smaller dima's with the createAndGetDistanceMatrix payload for createDistanceMatrix method

Dear Joost,

Thank you for your quick answer.

One more question. In the case of "smaller" matrices (up to 750x750), are there some other benefits of using xDima 1 instead of xRoute 1?

Hi Zoran,

thanks Joost for joining us here...

From my perspective I'd like to add some more info:

xRoute1 versus xDima1:

• If you create a "dima" through "xroute1.calculateMatrixInfo" the traveltimes and distances are returned to the client. The info is not stored on the server.
• If you create a "dima" through xDima1.createDIma + xDima1.calculateDistanceTable" the logical information is computed and stored on the server.
• If you want to get the "info" from xDima1 on the client you have to request "xdima1.exportDima" or "xdima1.getDistPeriod".
• If a "dima" is stored on the server it can be used by "xTour1" (running on the same infrastructure) for an optimization such as sequencing or tour optimization.
• In our cloud services known as "PTV xServer Internet 1" we do not offer the xDima1 modules.

Now let's compare some info from xServer1 versus xServer2:

• In xServer2 Internet the dima2 module is enabled.
• As mentioned by Joost: the xroute1.calculateMatrixInfo is replaced by xdima2.createAndGetDistanceMatrix

Well, in any case I recommend that Zoran and I set up 1:1 sessions to define the required methods and parameters from the xServer2 world to cover his current requirements...

Thanks,
Bernd

PS:

• Let's be careful with mentioning xServers. I recommend to add the major version number each time so we can be sure whether a statement refers to xserver1 or xserver2
• Furthermore one could try to distinguish also between synchronus and asynchronus request approaches but I guess for this post it is sufficient to stay on complexity level.

Hi Bernd,

once again, thank you for a detailed answer. For now, I have enough information to continue.

Best regards,

quick side note:
I love our implementation of XServer2 in OnPremise - haven't seen something that flexible and fast anywhere else.
