Ephemeral ports allocation policy
Ephemeral ports usages
- TCP & UDP clients typically do not specify a source port, thus an ephemeral port is allocated
- RPC services also run on dynamic ports
- After system startup, RPC services typically use ports immediately higher than 1024 (1025, 1026, 1028, ...)
Ephemeral ports allocation
- Incremental, starting from 1025
- Shared between TCP and UDP
