SNMP protocol standards define UDP to be used as the default protocol for communication. UDP, being a connectionless protocol, is most suitable for exchanging messages with smaller packet sizes. It is appropriate for the network management system that requires to perform quick queries on lot of devices. In case of database retrievals and updates, where the packet sizes are large, TCP might be the preferred protocol. Also developers might want to choose their own protocol for implementation, such as IPX, HTTP, TCP, Serial port communication, and so on. Users requiring more security can also implement SSL below the SNMP for secure communication.
To facilitate this, AdventNet SNMP API includes a new transport provider framework, whereby the users can plug-in their own transport protocol. This framework enables the developers to implement the protocol of their choice for SNMP communication. The API implements UDP/IP as the default protocol implementation. We also provide TCP/IP as the reference implementation that uses the transport provider framework.
