* Identifiers
|
|
** Problem description
|
|
Identifiers can be integers, strings or other objects. They should
|
|
be unique.
|
|
** Approach 1: integers
|
|
Integers are somewhat easy to remember, but also include
|
|
predictable growth, which might allow access to guessed hacking
|
|
(obivously proper permissions should prevent this).
|
|
** Approach 2: random uuids
|
|
UUIDs are 128 bit integers. Python supports uuid.uuid4() for random
|
|
uuids.
|
|
** Approach 3: IPv6 addresses
|
|
uncloud heavily depends on IPv6 in the first place. uncloud could
|
|
use a /48 to identify all objects. Objects that have IPv6 addresses
|
|
on their own, don't need to draw from the system /48.
|
|
*** Possible Subnetworks
|
|
Assuming uncloud uses a /48 to represent all resources.
|
|
|
|
| Network | Name | Description |
|
|
|-----------------+-----------------+----------------------------------------------|
|
|
| 2001:db8::/48 | uncloud network | All identifiers drawn from here |
|
|
| 2001:db8:1::/64 | VM network | Every VM has an IPv6 address in this network |
|
|
| 2001:db8:2::/64 | Bill network | Every bill has an IPv6 address |
|
|
| 2001:db8:3::/64 | Order network | Every order has an IPv6 address |
|
|
| 2001:db8:5::/64 | Product network | Every product (?) has an IPv6 address |
|
|
| 2001:db8:4::/64 | Disk network | Every disk is identified |
|
|
