Communication terminal, communication method, communication system, and program

摘要

A communication terminal communicating with a network including a control apparatus that generates a processing rule defining a packet processing method, the communication terminal comprises: a request unit that requests an address of the control apparatus when requesting for establishing a connection to the network; a communication unit that establishes a communication channel to the control apparatus based on an address acquired by the address request; and a processing unit that processes a packet based on a processing rule transmitted by the control apparatus via the communication channel.

主权项

1. A communication terminal, which communicates with a network including a plurality of packet forwarding apparatuses that forward a received packet, and a control apparatus that generates a processing rule defining a packet processing method for controlling the plurality of packet forwarding apparatuses, the communication terminal comprising:
a communication device; a memory storing instructions; and a processor configured to execute the instructions to:
request an address of the control apparatus when requesting for establishing a connection to the network;establish, using the communication device, a communication channel to the control apparatus based on an address acquired by the address request; andprocess a packet based on a processing rule transmitted by the control apparatus via the communication channel, wherein the processor is further configured to execute the instructions to perform at least one of the following:
notify whether the communication terminal holds the address;insert into the address request information indicating whether the communication terminal holds the address; orrefrain from requesting the address when the communication terminal holds the address.
