In a communication apparatus, a buffer offset calculator calculates a buffer offset for a transmission-ready state k-th communication unit in accordance with a total number of at least one of data packets that is (i) transmittable by at least one m-th communication unit in the N communication units except for the k-th communication unit and (ii) completely received by the recipient device within a data transmission period of the communication network corresponding to the k-th communication unit (m is each of variables 1 to N except for k). A data packet allocator selects, in a queue of the data packets stored in the transmission buffer, one of the data packets, a beginning of the selected data packet being located offset by the buffer offset relative to a beginning of the queue of the data packets. The data packet allocator allocates the selected data packet to the k-th communication unit.

A system may receive an instruction to execute a test represented by code in a test file. The system may initialize a first process instance associated with executing the test. The system may initialize a second process instance associated with loading the test file and executing the test. The second process instance may be different from the first process instance. The system may load the test file using the second process instance. The system may execute the test using the first process instance, the second process instance, and the test file without loading the test file into the first process instance. The system may update the test file during execution of the test without interrupting execution of the test.

A monitoring device (10) sets a first node (20A) that is a node on a transmission side that switches a route of a packet in user communication to copy the packet in the user communication, enable an INT setting, and transmit the copied packet to each of routes that are switching destination candidates based on an instruction input from a maintenance person. In addition, the monitoring device (10) sets a second node (20B) that is a node on a reception side that accommodates the routes that are switching destination candidates to collect INT information of the copied packet and discard the copied packet. Thereafter, the monitoring device (10) acquires the INT information of the copied packet from the second node (20B) and visualizes communication quality of each of the routes that are the switching destination candidates in the user communication based on the acquired INT information.
