Our company currently uses 3 licenses of CATIA.
![NSS](https://www.nss.co.th/blog/wp-content/uploads/2022/01/animal_panda-150x150.png)
How do you manage those CATIA licenses? Standalone or DSLS?
![Customer](https://www.nss.co.th/blog/wp-content/uploads/2021/02/business_woman3_1_question-150x150.png)
What is DSLS?
![NSS](https://www.nss.co.th/blog/wp-content/uploads/2022/01/animal_panda-150x150.png)
- DSLS (Dassault Systèmes License Server): A program that manages licenses of Dassault products.
- It is mandatory to deploy DSLS;
- when customer uses CATIA (Concurrent license) on Server / Client environment.
- Customer does NOT need to deply DSLS;
- when customer uses CATIA (Node lock license) as standalone.
- It is mandatory to deploy DSLS;

I see.
![Customer](https://www.nss.co.th/blog/wp-content/uploads/2021/02/business_woman3_1_question-150x150.png)
What is the difference between Node lock license and Concurrent license?
![NSS](https://www.nss.co.th/blog/wp-content/uploads/2022/01/animal_panda-150x150.png)
- Node lock license: A license issued and installed for the specific local computer.
- Customer can use CATIA only on this computer.
- Customer can use CATIA even when there is a LAN connection error.
- Concurrent license: A license issued and installed for the specific server.
- Customer can use CATIA on any computers installed SW (Client) in the same network.
- Customer cannot use CATIA when there is a LAN connection error.

- DSLS is installed on a server machine on your network.
- DSLS can manage both V5 and 3DEXPERIENCE at once.
![Customer](https://www.nss.co.th/blog/wp-content/uploads/2022/01/business_woman2_1_idea_resized-150x150.png)
I see. I think we currently uses Nodelock licenses.
![Customer](https://www.nss.co.th/blog/wp-content/uploads/2021/02/business_woman3_1_question-150x150.png)
By the way, in the future, we may sometimes need to use 3DEXPERIENCE CATIA not only at the office but also outside of the office, such as at a customer’s site or at home.
Can we do that?
![NSS](https://www.nss.co.th/blog/wp-content/uploads/2022/01/animal_panda-150x150.png)
Yes, there are 2 (two) ways with Concurrent license that support the use of outside the office.
- with DSLS
- Need a physical server
- Need VPN connection
- with Managed DSLS
- No Need a physical server
- No Need VPN connection
![NSS](https://www.nss.co.th/blog/wp-content/uploads/2022/01/animal_panda-150x150.png)
Here is the details.
With DSLS, Customer can use CATIA on any clients that are on the same network.
