Connection device and connection method using priority level information for a plurality of processes

Abstract

Provided is a technology for enabling smooth execution of a plurality of pieces of application software which perform communication via a communication path. A connection device includes: a storage unit which stores type priority level information for specifying a priority level assigned in advance for each type of a process, usable communication system information for specifying a usable communication system for each process, and sharing propriety information for specifying whether or not the communication system is sharable among a plurality of processes during the same period of time; a plurality of communication units which communicate to and from another device with use of the communication systems different from one another; and a communication system allocation control unit configured to identify the usable communication system and allocate, when the identified communication system is not sharable, the process to use the communication system based on the priority levels.
