METHOD FOR SERVICE CHAINING IN A COMMUNICATION NETWORK

摘要

The invention relates to a method, system, network node and computer program for processing packet data in a communication network, which comprises at least a first network node. In the method a first packet is received at the first network node. In the first network node is assigned for the first packet a chain comprising at least two logical service entities based on at least one service determination rule. A data unit comprising at least part of the first packet is formed. The data unit is processed in at least one logical service entity in the chain and a second packet is transmitted from the first network node comprising data sent by at least one logical service entity in the chain. The benefits of the invention relate to improved flexibility in introducing new value-added service for packet data and improved performance in the first network node.
