Communication Terminal Dynamic Control Address Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centrally controlled network architectures, such as OpenFlow, do not provide a method for communication terminals to dynamically change the control apparatus address when accessing different networks, making it difficult for them to establish and maintain communication channels.
Innovation Solution
A communication terminal with a request unit to acquire the address of the control apparatus, a communication unit to establish a channel based on the acquired address, and a processing unit to process packets according to rules received from the control apparatus, enabling dynamic adaptation to changing networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices establish control communication channel based on statically configured control apparatus address, then the control channel establishment is simple, but communication terminals cannot dynamically change control apparatus when accessing different networks
Solution Approach 1:
The patent makes the control apparatus address dynamic rather than static. Communication terminals automatically obtain the control apparatus address through DHCP options when accessing different networks, enabling the address to adapt to changing network environments without manual reconfiguration.
Solution Approach 2:
The patent enables communication terminals to automatically obtain and manage control apparatus addresses through DHCP without manual intervention. The terminal self-configures the control channel by receiving the control apparatus address automatically from the network infrastructure.
2Ease of operation
If control apparatus address is statically configured in communication terminal, then address management is simple, but terminal cannot automatically adapt when changing networks
Solution Approach 1:
The patent prepares the control apparatus address information in advance through DHCP configuration before the communication terminal needs to establish a control channel. The address is pre-loaded into the terminal during network initialization, so when the terminal moves to a new network, the new control apparatus address is already available without requiring manual input or causing service interruption.
3Adaptability or versatility
If communication terminal changes network frequently, then mobility and flexibility are improved, but maintaining control communication channel becomes difficult
Solution Approach 1:
The patent establishes a feedback mechanism where the communication terminal continuously monitors network changes and automatically updates the control apparatus address through DHCP. When the terminal detects a network change, it receives new control apparatus address information and re-establishes the control channel, ensuring continuous and reliable communication despite frequent mobility.

AI summary
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.
