The BACnet Router provides stand-alone routing between two different BACnet networks such as BACnet/IP, BACnet Ethernet, and BACnet MS/TP – thereby allowing the system integrator to mix BACnet network technologies within a single BACnet internetwork.
| BACnet IP |
| |
|---|---|---|
| BACnet IP uses a standard UDP/IP stack to send and receive messages. | MSTP stands for Master Slave Token Passing. Each device on the link is considered the “Master” when it has the Token and need to Pass the token along to the next device. | |
| BACnet IP describes the way BACnet networks may be formed from group of devices which uses the TCP/IP family of protocols for their communications. | BACnet MSTP is token passing protocol, where in MS stands for Master-Slave and the TP stands for Token Passing. BACnet MSTP is mainly used to connect field devices to controllers/routers/control applications. | |
| BACnet IP works over Ethernet Port. | BACnet MSTP works over RS-485 Port. | |
| BACnet IP is an Ethernet based Protocol. | BACnet MSTP is a Serial based Protocol. |

| Modbus RTU | Modbus TCP |
|---|---|
| Modbus RTU is Master – Slave Configuration. | Modbus TCP is Client – Server Configuration. |
| In Modbus RTU, there is only one Master Device that communicates over a single loop with multiple slave device. | In Modbus TCP, one or more than one Master Device communicates with single device. |
| It uses different serial physical interfaces (RS485-RS232). | It runs on an Ethernet physical layer. |
| Modbus RTU Supports Checksum. | Modbus TCP does not support Checksum. |
| When compared to Modbus TCP, it is less secured. | When compared to Modbus RTU, it is more secured. |
SNMP V1: It is simpler to set up and just require a plaintext network. But the drawback is that it doesn’t bolster bit counters and has a little security. It bolsters only 32-bit counters.
MP V2CSN: It is a sub-version of SNMP. The main advantage compared to the previous versions is an Inform Command. Traps are simply received by a manager, whereas Informs are positively acknowledged with a response message. If a manager does not reply to Inform, the SNMP Agent will resend the Inform.
SNMP V3: It is the latest version of SNMP and the main feature of it is an enhanced security. Each SNMP entity is uniquely identified in SNMP V3 with the EngineID Identifier. Problems may occur if two SNMP entities have duplicate EngineIDs. The EngineID generates the key for authenticated messages. SNMP V3 security generally comes in two forms, Authentication and Privacy.

MQTT uses the Publisher and Subscriber model to connect interested parties with each other. It does this by separating the sender who is known as the Publisher with the receiver who is called the Subscriber.
The Publisher publishes a message to a main topic that has many Subscribers waiting to receive the message.
The Publisher and Subscriber never meet each other directly. They even aren’t aware about an existence of the other.
Third person who is known as the MQTT Broker is the bridge between Publisher and Subscriber. Broker filters the messages and publishes the incoming messages effectively to the subscribed clients.
