Abstract: A packet processing method includes: a traffic classifier receives a first packet; the traffic classifier determines, in policy information in the traffic classifier and according to a first filtering rule that matches the first packet, a first service identifier that matches the first filtering rule, and an address, which matches the first filtering rule, of a first service routing trigger. The traffic classifier sends a second packet to the first service routing trigger. Where the policy information includes: a filtering rule, an address of a service routing trigger, and a service identifier corresponding to the filtering rule. Where the filtering rule is used to identify a packet, and the service identifier is used to represent a sequence of a service node that processes the packet. Where the second packet is formed by adding the first service identifier to the first packet.

Abstract translation: 分组处理方法包括：流分类器接收第一分组; 流分类器在流分类器的策略信息中，根据与第一分组匹配的第一过滤规则，确定与第一过滤规则匹配的第一服务标识符和与第一过滤规则匹配的第一服务标识符， 服务路由触发。 流分类器向第一个业务路由触发发送第二个报文。 策略信息包括：过滤规则，业务路由触发地址，以及与过滤规则对应的业务标识符。 其中使用过滤规则来识别分组，并且服务标识符用于表示处理分组的服务节点的序列。 其中通过将第一服务标识符添加到第一分组而形成第二分组。
