Hi,
I have some questions about upper limit of resources that can be created in OpenStack+OpenDaylight environment.
By reading netvirt source code, I found that there are upper limits of some resources.
*Without considered ODL memory capacity.
Could someone help to tell which resources have upper limit related to the code of netvirt, ovsdb and openflowplugin?
It will be appreciated if the specific upper limit value can be told too.
As far as my understanding, upper limits that netvirt code related are:
1. ELAN TAG
Used by : Virtual NW
How : As a part of cookie and metadata ID
Upper limit : 65536 (Hexadecimal, 4 digits)
*Q: Does this means tha the number of NWs that can be created is 65,536?
2. LPORT TAG
Used by : Open vSwitch and Port
How : As a part of cookie and metadata ID
Upper limit : 65536 (Hexadecimal, 4 digits)
3. tun_id
Used by : Virtual NW and local port
How : Store VNI for remote port, store LPORT TAG for local port
Upper limit : 16777216 (Hexadecimal, 6 digits)
*Q: Is it OK that different types of values are stored in tun_id?
Will there be a problem in the situation that VNI starts with 0x1, as LPORT TAG starts with 0x1 ?
○Environment Details:
