Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an event transmission process between a data link layer and a network layer in an OSI hierarchical model.
The present invention relates to a method , and more particularly, to a method of processing an event transmission between layers of a data link layer and a network for performing ISDN communication.

[0002]

2. Description of the Related Art A hierarchical model of OSI (Open System Interconnection) includes a physical layer, a data link layer having a transfer function, a network layer having a relay function, and the like.
Various events may be transmitted between these layers.

Conventionally, as such an event transmission system, an event queue 5 is set between each layer of a data link layer 3 and a network layer 2 of an OSI hierarchical model 1 as shown in a schematic diagram of FIG. Each event 6, 7, 8 generated in the data link layer 2 is transmitted to the network layer 2 through the event queue 5.

FIG. 4 shows a specific processing procedure in this case. First, as shown in FIG. 4A, an rivet queue 5 is established between the network layer 2 and the data link layer 3.
Next, as shown in FIG.
-9 occur. The generated events 6 to 9 are input to the established event queue 4 and are sequentially processed as shown in FIG.

[0005] Further, as shown in FIG.
When the events 6 to 9 input to the established event queue 5 are being processed, the generated events 11 to 14 are not input to the established event queue 5 but are generated. Event stays in the link layer 3 and becomes a busy event.
Will wait until it is processed.

[0006]

In this conventional event transmission method, there is only one event queue between the layers, so that there is a problem that a large control procedure time is required for event management and event processing. Was.

An object of the present invention is to solve such a problem, to provide a method of transmitting an event between layers in an OSI hierarchical model, in which management and processing of an event is speeded up and control time is reduced.

[0008]

According to the present invention, there is provided an inter-layer event transmission processing method in an OSI hierarchical model comprising a plurality of event queues as physical channels between a data link layer and a network layer in the OSI hierarchical model. But,
Exchanges of data transfer process events that occur in the data link layer to the network layer, the
Event queues other than one of the multiple event queues
But wherein at close event queue the event with established between the layers is activated upon the occurrence of predetermined <br/> number
Oh it is, and said to be able to handle each event in parallel between each event queue.

[0009]

FIG. 1 is a schematic diagram showing an event transmission processing method between a data link layer and a network layer in an OSI hierarchical model for explaining an embodiment of the present invention. Each event 5-9 that occurred in the data link layer 3 of the OSI hierarchical model 1
Enters the first event queue 5 and enters the network layer 2
To be processed in the network layer 2. Here, when the event 11 occurs in the data link layer 3 and the event cannot be processed in the first event queue 5, it is input to the second event queue 10, transmitted to the network layer 2, and transmitted to the network layer 2. Let it process inside.

FIG. 2 shows a specific processing procedure in this case. First, a first event queue 5 is established between the network layer 2 and the data link layer 3 as shown in FIG. Here, it is assumed that the closed event queue 10 is always established.

Next, it is assumed that events 6 to 8 occur in the data link layer 3 as shown in FIG. The generated event is input to the established event queue 5, and
As shown in (c), events 6 to 8 are sequentially processed.
If the event queue exceeds the maximum number of events that can be accepted, the closed event queue 10 is opened. The event queue 10 has the data link layer 3
FIG. 2 by sequentially inputting events 11 to 13 occurring in
Processing is performed in parallel as shown in (d).

[0012]

As described above, the present invention facilitates event management by setting two or more event queues for performing event transmission processing between the data link layer and the network layer in the OSI hierarchical model. And the time required for processing the event that has occurred can be reduced.
