CC1312R7: WiSUN Border Router Routing Table storage

Thiago Rocha

Part Number: CC1312R7

Hi,

Since the network size is limited to 100 nodes because of the RAM memory of the BR (using CC1312R7), I wanted to know if the routing table is stored with dynamic or static memory allocation and where I can see that information within the code. Also, can we change the maximum size of the network, to 10 for example, for testing purposes? If that's the case, where should I look to change those parameters?

Thanks in advance.

    Hi Thiago, 

    The storage for the routing table is allocated dynamically. So the maximum limit is not implemented up front for the routing table. The 100 node limit is something that was identified after testing. 

    There is no place in code where you can limit this number easily. You could look into the mbed nanostack code in the ns_br_src projects in the SDK and see if you can find something you can work with. 

    Regards,
