US 2017/0288998 A1 · APPARATUS FOR PROCESSING NETWORK PACKET USING SERVICE FUNCTION CHAINING AND METHOD FOR CONTROLLING THE SAME

Abstract

A network packet processing apparatus using a service function chaining and a method of controlling the same are provided. The network packet processing apparatus includes a plurality of service function modules configuring the service function chaining, each of the plurality of service function modules being one of a stateful service function module and a stateless service function module. Also the network packet processing apparatus includes an input logger and an output logger used to perform fault-recovery, and a service function forwarder module forwarding a packet to the plurality of service function modules, the input logger, and the output logger through a path specified in the packet.

Dependent claims

A network packet processing apparatus using a service function chaining, comprising:

a plurality of service function modules configuring the service function chaining, each of the plurality of service function modules being one of a stateful service function module and a stateless service function module;
an input logger and an output logger used to perform fault-recovery for the stateful service function module of the plurality of service function modules;
and
a service function forwarder module forwarding the packet to the plurality of service function modules, the input logger, and the output logger through a path specified in the packet.

A method of controlling a network packet processing apparatus using a service function chaining, the network packet processing apparatus including a plurality of service function modules, an input logger, an output logger, and a service function forwarder module, the method comprising:

transmitting a packet to the input logger, by the service function forwarder module;
transmitting the packet to the service function forwarder module after storing the packet, by the input logger;
transmitting, by the service function forwarder module, the packet to a service function module A, a stateful service function module of the plurality of service function modules;
processing the packet, generating a packet access log(PAL) with respect to the packet, and transmitting the packet and the packet access log to the service function forwarder module, by the service function module A;
transmitting the packet and the packet access log to the output logger, by the service function forwarder module;
and
transmitting the packet access log to a backup service function module of the service function module A, by the output logger.
