Goal
Differentiated services or DiffServ is a computer networking architecture that specifies a simple and scalable mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks. DiffServ can, for example, be used to provide low-latency to critical network traffic such as voice or streaming media while providing simple best-effort service to non-critical services such as web traffic or file transfers.
DiffServ uses a 6-bit differentiated services code point (DSCP) in the 8-bit differentiated services field (DS field) in the IP header for packet classification purposes.
RFC 4594 offers detailed and specific recommendations for the use and configuration of code points.
IETF RFC 4594 recommendations:
| Service class | DSCP Name | DSCP Value | Conditioning at DS edge | PHB | Queuing | AQM |
| Network control | CS6 | 48 | See section 3.1 from RFC 3246 | RFC 2474 Rate | Rate | Yes |
| Telephony | EF | 46 | Police using sr+bs | Priority | No | |
| Signaling | CS5 | 40 | Police using sr+bs | RFC 2474 Rate | Rate | No |
| Multimedia conferencing | AF41, AF42, AF43 | 34, 36, 38 | Using two-rate, three-color marker (such as RFC 2698) | RFC 2597 Rate | Rate | Yes per DSCP |
| Real-time interactive | CS4 | 23 | Police using sr+bs | RFC 2474 Rate | Rate | No |
| Multimedia streaming | AF31, AF32, AF33 | 26, 28, 30 | Using two-rate, three-color marker (such as RFC 2698) | RFC 2597 Rate | Rate | Yes per DSCP |
| Broadcast video | CS3 | 24 | Police using sr+bs | RFC 2474 Rate | Rate | No |
| Low-latency data | AF21, AF22, AF23 | 18, 20, 22 | Using single-rate, three-color marker (such as RFC 2697) | RFC 2597 Rate | Rate | Yes per DSCP |
| OAM | CS2 | 16 | Police using sr+bs | RFC 2474 Rate | Rate | Yes |
| High-throughput data | AF11, AF12, AF13 | 10, 12, 14 | Using two-rate, three-color marker (such as RFC 2698) | RFC 2597 Rate | Rate | Yes per DSCP |
| StandardLow-priority data | DF | 0 | Not applicable | RFC 2474 Rate | Rate | Yes |
| Low-priority data | CS1 | 8 | Not applicable | RFC 3662 Rate | Rate | Yes |
