受影響的文件：“Priority Values” in System Administration Guide, Volume 3

此 4 位元「Priority」欄位的說明指的是 RFC 1883，但是 RFC 1883 已因被 RFC 2460 取代而棄用 (Solaris 8 執行的是 RFC 2460) 。 因此，「Priority」欄位已由一個 8 位元的「Traffic Class」欄位所取代。「Priority」區段也應以下面的「Traffic Class」區段來取代。

Traffic Class

Originating nodes and forwarding routers can use the 8-bit Traffic Class field in the IPv6 header to identify and distinguish between different classes or priorities of IPv6 packets.

The following general requirements apply to the Traffic Class field.

• The service interface to the IPv6 service within a node must provide a means for an upper-layer protocol to supply the value of the Traffic Class bits in packets originated by that upper-layer protocol. The default value must be zero for all 8 bits.

• Nodes that support a specific use of some or all of the Traffic Class bits can change the value of those bits in packets that they originate, forward, or receive, as required for that specific use. Nodes should ignore and leave unchanged any bits of the Traffic Class field for which they do not support a specific use.
