Abstract: A service node capability processing method and apparatus, a service classifier and service controller are described. The method includes: determining an exchange information set of service nodes on a service function chaining for processing a data packet, wherein the exchange information set includes an intersection of capabilities of the service nodes on the service function chaining; and encapsulating the exchange information set in the data packet, wherein the exchange information set is used for the service nodes to read a processing result which is obtained by processing capability corresponding to the intersection of the capabilities of the service nodes and which is encapsulated in the data packet. In such a fashion, the problem in the related technology is addressed that the blind information exchange causes the waste of resources since the information exchange between nodes is untargeted, and consequentially effectively avoids the waste of field resources by invalid information exchange.
