For some network services, traffic is forwarded through a sequence of network functions, which usually have dedicated capabilities other than forwarding, e.g. firewall. Forwarding of traffic along a sequence of service processing functions is usually based on service characteristics, but not destination addresses. We call such way of forwarding as service chaining.
