802.1p

A draft standard

of the IEEE about data traffic prioritization on Ethernet networks. The 802.1p

 

 

 

draft is an extension of the 802.1D bridging standard. 802.1D determines how prioritization

 

 

 

will operate within a MAC-layer bridge for any kind of media. The 802.1Q draft for virtual

 

 

 

local-area-networks (VLANs) addresses the issue of prioritization for Ethernet networks in

 

 

 

particular.

 

 

 

 

 

802.1p enacts this Quality-of-Service feature using 3 bits. This 3-bit code allows data switches

 

 

 

to reorder packets based on priority level. The descriptors for the 8 priority levels are given

 

 

 

below.

 

 

 

 

 

802.1p PRIORITY LEVELS:

 

 

 

LOWEST PRIORITY

 

 

 

1 – Background: Bulk transfers and other activities permitted on the network, but should not

 

 

 

affect the use of network by other users and applications.

 

 

 

2 – Spare: An unused (spare) value of the user priority.

 

 

 

0 – Best Effort (default): Normal priority for ordinary LAN traffic.

 

 

 

3 – Excellent Effort: The best effort type of service that an information services organization

 

 

 

would deliver to its most important customers.

 

 

 

4 – Controlled Load: Important business applications subject to some form of “Admission

 

 

 

Control”, such as preplanning of Network requirement, characterized by bandwidth

 

 

 

reservation per flow.

 

 

 

5 – Video: Traffic characterized by delay < 100 ms.

 

 

 

6 – Voice: Traffic characterized by delay < 10 ms.

 

 

 

7 - Network Control: Traffic urgently needed to maintain and support network

 

 

 

infrastructure.

 

 

 

HIGHEST PRIORITY

 

 

 

 

 

Sets the priority for signaling packets. 0 is lowest priority.

 

Call Control Priority

0-7

 

 

 

 

 

 

Sets the priority for media packets. 0 is lowest priority.

 

VOIP Media Priority

0-7

 

 

 

 

 

 

Sets the priority for SMTP, DNS, DHCP, and other packet types. 0 is lowest

 

Others (Priorities)
