Abstract

PURPOSE:To conduct the flexible communication processing by storing a communication request from plural processes through the control of a transmission and reception order depending on the priority and sending/receiving communication data depending on the order. CONSTITUTION:Application processes 11a-11c in an application 1 of a network equipment add a request attribute to communication data on the occurrence of a communication request in the inside and sends a communication request to a communication request reception section 3 by inter-process communication. A communication request management section 4 receiving a notice from the communication request reception section 3 references a request attribute of the communication request and stores it to a storage section 6 of a processing wait request. The communication requests are stored in a queue in the order of priority and when the priority of the communication request newly received is high, the queue is updated. Then a communication processing section 5 makes transmission reception processing to a transmission line 7 for the communication requests controlled by the communication request management section 4 in the order of higher priority.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication task management system for managing communication requests in a network device.

[0002]

2. Description of the Related Art In a conventional communication task management system, a communication request generating unit for generating a communication request and a communication processing unit for receiving a communication request and transmitting / receiving data are provided in the network device. The communication request is transmitted to the communication processing unit, and the process of transmitting / receiving data corresponding to the request content received by the communication processing unit is performed on the transmission path. When the communication requests are duplicated at the same time, the queues are stored in the order in which the communication requests are received, and the sequential processing is performed.

[0003]

In this conventional communication task management system, since the processing order for the transmission path is the order in which the communication request is received, for example, the communication received after the communication request received first Even if the request requires a higher processing priority, it is difficult to perform the processing efficiently, such as waiting until the processing of the preceding communication request is completed. Moreover, since no control is possible for the communication request stored in the queue,
Flexible management of communication requests is difficult. Practically, the processing unit corresponding to the communication request generation unit in the network device is pluralized, and the above-mentioned problem seems to be remarkable.

[0004]

[Means for Solving the Problems] The communication task management system is
A request receiving unit that receives a communication request from a plurality of processes that communicate with each network, a communication request management unit that stores the communication request in a storage unit by controlling the transmission / reception order, and the communication And a communication processing unit for transmitting / receiving communication data to / from a transmission line according to the transmission / reception order controlled by the request management unit.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The application processes 11a, 11b, 11c in the application 1 of the network device are
When a communication request is generated internally, a request attribute is added to the communication data, and the communication request is transmitted to the communication request receiving unit 3 by interprocess communication. The communication request reception unit 3 notifies the communication request management unit 4 that the communication request has been received. Upon receiving the notification, the communication request management unit 4 refers to the request attribute of the communication request, and then stores the processing wait request in the corresponding position of the storage unit 6 for storing the processing wait request.

FIG. 2 is a format diagram showing the internal structure of the storage unit 6 of this embodiment. Communication request has priority 63d
Are stored in the queue 61 in this order. The queue 61 is reconfigured each time the priority of the newly received communication request is high. Further, the queue 61 can specify its attribute by the queue attribute table 67. Furthermore, in the communication request management unit 4, when it is desired to change the priority of the communication request depending on the state of the network and the processing,
This is possible by rewriting the priority correspondence table 64. The priority correspondence table 64 is for converting the priority 66a added to the communication request into the priority 63d in the queue 61. This table enables detailed priority operations.

From among the communication requests controlled by the communication request management unit 4, the communication processing unit 5 sets the transmission path 7 in descending order of priority.
And the transmission / reception processing is performed.

In the present embodiment, the functions described above enable communication according to the state of the network device and the priority of processing, and communication processing more efficient than the conventional method can be performed.

[0010]

As described above, according to the present invention, by providing the communication request management section independent of the communication request generation process, the communication processing is flexible according to the priority of processing and the state of the network device. Is possible.

Further, it is possible to change the priority order of communication without changing the processing of the communication request generation process, and unnecessary communication data can be deleted by the communication request management unit if necessary. The load can also be reduced.
