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.

Implementing Policy Criteria in Intermediate Switching Device

• Verification of preceding device’s signature.
• Implementing plural policy criteria.

Implementing Policy Criteria

• Add or modify flow entries in intermediate switching device flow table.
