Problem Statement
- A software-defined networking architecture allows a computer network to transmit data packets between multiple computing devices using various components like a switching device and a controlling device.
- The communication is initiated by a source device, which transmits the data packet to a destination device.
- The objective is to reduce the number of interactions used to obtain the packet forwarding policy between the controlling device and the plurality of switching devices.
Technology
Key Features/Value Proposition
Switching Device Advantages
- Processes and transmits data packets in software-defined networking environment.
Source address:
- MAC address of source computing device.
Destination address:
- MAC address of destination computing device.
- Controlled by SDN controller.
Switching Device Policy
- Receives multiple policy criteria from controlling device.
- Receives header information if no policy criteria present.
- Provides policy criteria based on data packet header information.
- Installs one of the received policy criteria from the controlling device.
- Includes addresses of subsequent network switching devices for data packet flow.
- Encapsulates data packet with a signature of the switching device
Intermediate Switching Device Implementation Method
- Hardware or software-based application.
Method for Receiving Policy Criteria
- Combines multiple policy criteria into flow entries.
