1)
Applications which need not to be solid and can send information without associations among worker and customer and requirements to send a lot of information can work without a transport protocol. For instance online streaming applications they do no compelling reason to set up connection. They can utilize UDP (User Datagram Protocol) to send packet of data.
2)
Issues that modern network would confront:
Irregularity
If there is no transport protocol then data can't be sending appropriately and will be lost at the hour of transmission which will prompt the irregularity of the application.
Reliability
Without transport protocol the application and administrations won't be solid and will lose their effect.
Scalability
Thesoftware won't have the option to send enormous measure of information if there is no transport layer.
Data Loss
Data will be lost if send without an appropriate association and will prompt sending of wrong data.
Inertness
Without appropriate association data packets will reach no concurrently and the data will be adjusted.
