System Requirements

Top  Previous  Next

RW NetServer requires Windows NT4, 2000, XP, 2003 or 2008. 32 or 64-bit can be used.

Linux (x86) is also possible with kernel 2.2 or 2.4. We have tested with quite a few distributions, including Ubuntu 4 and SUSE 64-bit distributions.

 

CPU

A fast CPU is always a good idea, but any modern computer will do. It is only if you are using very large street databases or are expecting massive amounts of routing requests, that it may be needed to test if you need a multi-processor machine or the fastest possible CPU's.

 

Harddisk

RW NetServer uses the harddisk for some operations, but generally a fast harddisk is not important.

 

RAM

To determine, how much RAM is needed by RW NetServer you can use this approximation:

 

(34 + Limits + 12 * MT) * L bytes for networks without turn restrictions

(34 + Limits + 23 * MT) * L bytes for networks with turn restrictions.

 

MT = Maxthread

L = Number of links in the network

Limits = 0 - 3 depending on the number of limits in the network.

 

Example:

700,000 links

2 limits (width, height)

Turn restrictions

3 threads

 

(34 + 2 + 23 * 3) * 700,000 = 70 MB.

 

If you have too little RAM, you can select a lower number of max threads, split the networks between several routing servers (if you have >1 network), add more RAM or skip support for turn restrictions. Which solution is the best, depends on your specific set-up.

 

Simplification of the network is also a possibility. This involves either deleting links of less importance or removal of pseudo-nodes. For removal of pseudo-nodes, look at function Join in RW Net Pro or RouteFinder Pro. See also section on very large networks.

 

Additional software

 

No more software is needed except a client to access the server and a tcp/ip stack.
