Cipher suite name is made up of :
- TLS prefix
- Key Exchange algorithm
- Authentication algorithm
- EncyptionEncryption algorithm
- Encryption strength
- Encryption mode
- MAC or PRF function (depending on TLS version)
In your case elliptic curve diffie-hellman key exchange will be used in ephemeral mode (which provides forward secrecy) and this exchange will be authenticated with RSA signature.
