said processor using said network trend analysis and protocol switching control performs: providing a system and network metrics monitor monitoring system and network metrics at multiple system nodes; providing a storage coupled to said system and network metrics monitor storing historical patterns; automatically choosing a transport protocol based upon data analysis of real time monitored system and network metrics and learned and predicted patterns for system and network metrics; automatically and dynamically switching the transport protocol for data being transmitted between nodes responsive to automatically choosing the transport protocol; and automatically and dynamically switching the transport protocol includes establishing a default Transmission Control Protocol (TCP) connection, periodically collecting network and system metrics to determine Quality of Service (QOS), identifying a QOS threshold reached, changing transport protocol to a selected one of a plurality of different protocols; applying the transport protocol to at least one of network segments, network switches and between systems; identifying a QOS decrease, changing back to Transmission Control Protocol (TCP), with cached packets in buffer being replayed.

2 . The computer-implemented method as recited in claim 1 wherein changing transport protocol to a selected one of a plurality of different protocols includes changing transport protocol to a selected one of User Datagram Protocol (UDP), Quick UDP (QUIC), and Stream Control Transmission Protocol (SCTP) and includes performing and applying historical trend analysis of connections and system data to provide a real time protocol determination.

3 . The computer-implemented method as recited in claim 1 wherein monitoring system and network metrics include monitoring network quality, historical network data, and previous node data.

4 . The computer-implemented method as recited in claim 1 includes storing and using historical patterns and at least one threshold for protocol switchover.

5 . The computer-implemented method as recited in claim 4 includes receiving a user application input and setting said least one threshold.

6 . The computer-implemented method as recited in claim 1 includes performing learned protocol switching for optimal performance based upon the monitored system and network metrics.

7 . The computer-implemented method as recited in claim 6 includes learning historical congestion patterns and predicting congestion metrics.

8 . The computer-implemented method as recited in claim 1 wherein automatically choosing said transport protocol based upon monitored system and network metrics includes selecting a transport protocol to apply on network segments, switches, and between systems.

9 . The computer-implemented method as recited in claim 1 wherein monitoring system and network metrics include monitoring data size being selected and a data type.

a processor; a network trend analysis and protocol switching control; said processor using said network trend analysis and protocol switching control performs: a system and network metrics monitor monitoring of system and network metrics at multiple system nodes; said system and network metrics monitor coupled to a storage storing historical patterns; automatically choosing a transport protocol based upon data analysis of real time monitored system and network metrics and learned and predicted patterns for system and network metrics; automatically and dynamically switching the transport protocol for data being transmitted between nodes responsive to automatically choosing the transport protocol; and automatically and dynamically switching the transport protocol includes establishing a default Transmission Control Protocol (TCP) connection, periodically collecting network and system metrics to determine Quality of Service (QOS), identifying a QOS threshold reached, changing transport protocol to a selected one of a plurality of different protocols; applying the transport protocol to at least one of network segments, network switches and between systems; identifying a QOS decrease, changing back to Transmission Control Protocol (TCP), with cached packets in buffer being replayed.

11 . The computer system as recited in claim 10 , includes control code stored on a computer readable medium, and wherein said processor uses said control code to implement dynamic switching of network protocols.

12 . The computer system as recited in claim 10 wherein changing transport protocol to a selected one of a plurality of different protocols includes changing transport protocol to a selected one of User Datagram Protocol (UDP), Quick UDP (QUIC), and Stream Control Transmission Protocol (SCTP) and includes providing a buffer for buffering data with selected transport protocol switching.

13 . The computer system as recited in claim 10 wherein monitoring of system and network metrics includes monitoring network quality, historical network data, and previous node data.

14 . The computer system as recited in claim 10 wherein monitoring of system and network metrics includes performing historical trend analysis of connections and system data.

15 . The computer system as recited in claim 10 wherein monitoring of system and network metrics includes monitoring a number of independent data streams between a source and sink.

16 . The computer system as recited in claim 10 wherein automatically choosing said transport protocol based upon the monitored system and network metrics includes predicting an optimal transport protocol to apply on network segments, switches, and between systems.

17 . The computer system as recited in claim 10 wherein monitoring of system and network metrics includes learning historical congestion patterns and predicting congestion metrics.
