Systems and methods for controlling data transaction between master and slave devices are described. A master device can be connected to multiple slave devices that can operate under one of a first, a second, and a third operation modes. The first operation mode can cause the master device to perform data transactions with the multiple slave devices via a network element and the multiple slave devices can be connected to one another via the network element. The second operation mode can disconnect the master device from the multiple slave devices, and multiple agents connected to the multiple slave devices can fulfill the data transactions. The third operation mode can cause the master device to perform data transactions with a first subset of the multiple slave devices via the network element, and can cause the master device to be disconnected from a second subset of the multiple slave devices.

Network device configuration based on slave device type

Systems and methods for routing communication among a plurality of devices are described. In an example, a controller can detect a communication initiated from a first device to a target device among a second device and a third device. The controller can identify the second device as the target device. The controller can, in response to identifying the second device as the target device, activate a direct communication path between the first device and the second device to allow the first device to communicate with the second device using direct communication mode. The controller can, in response to identifying the second device as the target device, activate redriver path between the first device and the third device to allow the first device to communicate with the third device using redriver mode.

Controller with direct communication and redriver modes

Apparatuses for controlling data transaction between master and slave devices are described. A master port connected to a master device can include a voltage regulator, a bridging circuit connected to a network element, and a redriver circuit. In response to a data transaction corresponding to a first type of data transaction, the master port can activate the voltage regulator and deactivate the redriver circuit to support a first operation mode causing the master device to perform the data transaction with a slave device via the network element. In response to the data transaction corresponding to a second type of data transaction, the master port can deactivate the voltage regulator and activate the redriver circuit to support a second operation mode causing the master port to disconnect from a slave port connected to the slave device and the data transaction is fulfilled by a circuit connected to the slave device.
