Description

Detailed Description of the Invention

[0001]

[Industrial field of use] Control information such as codes that describe communication / information processing related processing definition programs and processing procedures are transmitted as a set from data to other station nodes that have databases required for execution from their own node. The present invention relates to a communication / information processing control system in which a destination node executes a processing definition program or processing procedure code.

[0002]

2. Description of the Related Art Generally, in a communication / information processing control system that realizes advanced communication / information services by connecting communication / information processing nodes that perform communication processing and information processing by a transmission line,
As shown in FIG. 1, the own station node has a processing program, and data required for execution is acquired from a database of another station node via a transmission line (network) to execute information processing.

However, in such a method, (1) even if there is no data to be transmitted through the network, the communication line remains connected until the processing between the local station node and the remote station node is completed. Inefficient in the state (2) With the increase of data transmission through the network,
There is a problem that control of data transmission becomes extremely complicated and communication time for data transmission increases.

Therefore, conventionally, in order to effectively use the network, eliminate the complexity of data transmission control, and shorten the communication time, as shown in FIG. 15, a node 1 having a database 2 and the like necessary for execution is provided. In addition, communication / information processing related processing definition program 3, control information such as a code that describes a processing procedure is transmitted as a set with data 4, and the destination node 5 executes the processing definition program and the processing procedure code. The concept of information processing system is being proposed. Reference numeral 6 is a transmission line.

In the communication / information processing system based on such a concept, not only the above-mentioned problems can be solved but also the mobile node can autonomously move in the communication network to request the movement-destination node to instruct and execute the processing. Therefore, there is an advantage that it is possible to provide a high-level communication / information service by utilizing a node in the communication network.

The prior art of the system described above includes telescript and literature: 1989 IEICE Spring National Convention B-356 "Proposal of Communication Method by Intelligent Cell" (3-62, Hitoshi Imagawa et al. , NTT
Switching Systems Laboratories), JP-A-63-97041 and JP-A-5-25208 are known.

However, in such a conventional communication / information processing system, there are studies on authentication, billing, and validity period defining methods. (1) Method of notifying process progress and status during communication / information processing ( 2) Method of changing processing contents such as continuation / extension / stop of communication / information processing (3) Communication / information processing range defining method (4) Communication / information processing transfer history storage method (processing unit search result storage method), etc. Was not suggested at all.

A packet that is a set of control information and data necessary to realize accumulated elapsed time in a communication network such as a code that describes a communication / information processing related processing definition program and a processing procedure is described. Hereinafter, it will be referred to as an active packet.

There is a problem that the processing cannot be performed, or the processing cannot be canceled even if the user wants to cancel the processing request. (3) Since the range of communication / information processing is not specified in the active packet, requesting more processing than necessary may cause system congestion, or the packet may be transferred indefinitely for some reason. If it continues, it cannot be excluded from the system, and there is a problem that the transfer band of the system is pressed. (4) Since the search result of the processing unit, which is performed when there is no processing unit capable of executing the requested processing, is not stored, in response to the same service request,
There is a problem that it is inefficient because it is necessary to search for an executable processing unit every time.

And that the service control information for providing a broadcast service, it is.

Also, the difference between the operation of step (S6) in FIG. 6 and the operation of step (S6) in FIG. 5 is that in step (S6) in FIG. 6 an active packet transmitted by the service management node 4 is created. While providing the desired communication / information processing service to the service receiving node 6, in step (S6) of FIG. 5, an active packet sent by the service sending node 1 is created to send the desired communication / information processing to the service receiving node 6. The point is to provide information processing services.

Further, the step (S4) in FIG.
Although the operation of (S6) is not always necessary when the desired communication / information processing service is provided from the service transmission node 1 to the service reception node 6, the operation of step (S6)
4) and (S5) may be performed. In this case,
In the operation of step (S3) of FIG. 5, as in step (S3) of FIG. 4, service control information for providing a desired communication / information service from the service transmitting node 1 to the service receiving node 6 is also created. Is.

That is, FIG. 5 shows a method in which the service transmission node 1 receives the service control information from the service management node 4, creates an active packet for realizing the service to the service reception node 6, and directly realizes the service. However, in FIG. 6, the service management node 4
Is a method for realizing a service to the service receiving node 6 by creating an active packet on behalf of the service transmitting node 1.

FIG. 7 is a diagram for explaining step (6) in the description of FIG. 5 in more detail. That is, the active packet (operation of (A)) transmitted from the service transmission node 1 is divided by the communication processing node 8 as an active packet for the communication / information processing nodes 9 and 10 ((B), (C)). ) Operation). Next, the communication / information processing nodes 9 and 10 that have received the divided active packets execute processing (a) and processing (b) based on the control information and data of each active packet,
The processing result is transferred to the communication / information processing node 11 (operations (D) and (E)). Communication that received the processing result
When the information processing node 11 receives an active packet containing one of the processing results, it executes processing (c) within the feasible range and waits for the reception of an active packet containing the remaining processing results. Next, the communication / information processing node 11 that has received the active packet including the remaining processing result is released from the data waiting state, continues the processing (C), and obtains the final result. Further, when the process (C) is completed, an active packet for the service receiving node 6 is created and transferred to the service receiving node 6 ((F)).
Behavior).

Then, the service receiving node 6 which receives the active packet from the communication / information processing node 11
Performs processing (d) based on the control information and data set of the received active packet, and the desired communication / information service is provided.

FIG. 8 shows (6) in the explanation of FIG.
FIG. 5 is another diagram illustrating in more detail. 7 and 8
The difference is that the communication / information processing node 8 merely relays an active packet, and the communication / information processing node 11 in FIG. Yes (in this case, the communication / information processing node 11 may or may not have an active packet before division).

What was desired in FIG. 8 is that even if the execution result of the processing requested by the communication / information processing node does not return to the request source (node 8) as shown in FIG. Even if the processing result is returned to the request source (node 11) as shown in FIG. 7, both of them may be performed at the same time.

Further, FIG. 8 is a diagram showing a process when the change of the process is performed remotely after the active packet realizing the same process flow as in FIG. 6 is transmitted from the service transmitting node 1.

In FIG. 8, steps (A) to FIG.
The processing up to (C) is completed, and the communication / information processing node 9 shows the processing (a) being executed.

Here, as a method of remotely changing the processing after the active packet leaves the user's hand, it can be realized by the sequence shown in the following steps (T1) to (T6), for example. . That is, (T1) First, the service originating node 1 notifies the service receiving node 6 of the prohibition of reception of an active packet whose processing is about to be changed, and discards it when a corresponding active packet arrives. Note that a node different from the one shown in the drawing may be used as to which transmission path is used. (T2) Next, in order to notify the process change, the route through which the active packet before the change has passed is traced, and the process after the process related to the process change is canceled and the result is discarded.

For example, when both the process (a) and the process (b) are related to the process change, the routes of (T3) and (T4) are traced, and in the process (a), the process being executed is canceled. ,
In the process (b), the process queue is removed. (T5) Next, the service transmission node 1 notifies the service reception node 6 of the reception permission of the active packet which is about to be changed in processing. (T6) Then, the process is restarted by using the active packet after the process change from a place related to the process change.

Here, in the case of remote control of an active packet that is being processed from the source node, as a method of tracing the passage route of the active packet before the change, each communication / information processing is performed without notifying the transfer history information. As the corresponding active packet is passed to the node,
If the next node identification number and the transmission line number are stored, the same route can be easily followed.

Further, FIG. 9 shows the processing of the communication / information processing node to which the active packet has moved from the remote node after the active packet realizing the same processing flow as in FIG. 7 is transmitted from the service transmission node 1. It is a figure which shows operation | movement when it wants to grasp | ascertain the progress and state of.

In FIG. 10, (A) to (C) in FIG.
The process up to is completed, and the communication / information processing node 9 shows the process (a) being executed.

Here, in FIG. 7, as a method of notifying the progress and status of the processing of the communication information processing node to which the active packet has moved to the remote node, (U1)-
There is a method (U4). When the communication / information processing node 11 reaches the condition set in the received active packet or determines that the communication / information processing node 11 is abnormal, (U1) determines that the remote node (in this case, , The process origination and status of the communication / information processing node are notified even if there is no request from the service originating node 1). Here, the notification condition of the communication / information processing node 11 is not limited to the above example, and the communication / information processing node 11 may periodically notify. (U2) shows a case where the service originating node 1 wants to know the processing progress and status of the communication / information processing node 11, and the communication / information processing node 11 requests the remote user (service originating node 1) to make a request. The response indicates that the user can know the processing progress and status of the communication / information processing node 11. (U3) shows a case where the communication / information processing node 11 wants to know the process progress and status of the communication / information processing node 10, and the communication / information processing nodes in the network also use the request-response format in the remote node. It is shown that it is possible to know the processing progress and status of the communication / information processing node. (U4) indicates that the communication / information processing nodes 9 and 11 notify each other of the operation states of the communication / information processing nodes and the OAM information of the network.

In any of the methods (U1) to (U4) shown here, the remote node wants to know the state of communication /
A method by which a user knows the state of the network ((U1), (U2)) and a method by which an internal node of the network knows the state of the network ((U3), under the assumption that the user knows how to access the information processing node. (U
4)).

If the remote node wants to know the progress and status of the current communication / information processing without specifying the communication / information processing node (don't know which communication / processing node should be accessed), In 8, similar to the case where the processing contents are changed from the remote node, the active packet passing route is traced so that the communication / information processing node currently executing the processing can inform the network state. Just do it.

FIG. 10 is a diagram showing an operation according to the present invention when the method for realizing the communication / information processing service for the service request of the service originating node 1 is unknown and there is no service management node.

As shown in FIG. 10, the service originating node 1 selects the desired communication / information processing service from (P1) to (P1).
It is realized by the sequence shown in 3). That is, (P1) First, the service originating node 1 accesses the local cache memory 2 based on the service request information, and confirms whether the service flow information for realizing the desired service is registered. (P2) When it is confirmed that the service flow information for realizing the desired service is not registered in the local cache, the service originating node 1 sends the service request information to the network ((Q1) operation diagram). (Refer to 11) The communication / information processing node capable of responding to the service request sends back the service processing function (necessary input information, processing function, output information) of the own node and the address information of the own node ((Q2), ( Operation of Q3) and (Q4)) (refer to FIG. 11 service processing node acquisition phase).

At this time, the service processing function information returned from the communication / information processing node includes a processing function related to the service request this time and a list of processing functions that can be realized by the node. You may stay.

If the local host (service transmission node 1 or service reception node 6) obtains a list of the functions that can be processed by the communication / information processing node in the network and stores it in the local cache memory, ( P
By the operation of 1), even if the service flow information is not registered, by referring to the communication / information processing node function list stored in the local cache memory,
It is possible that the service flow information can be created on the local host without performing the operation of (P2).

In the above description, the service flow information created as a result of interpreting the service requested by the user is stored in the local cache memories 2 and 7. However, in this case, it exists inside the network. It is described that what kind of service identifier (the smallest unit for realizing a service) that corresponds to the corresponding communication / information processing node is stored, and that service parameter information is stored in the local cache memories 2 and 7. Although it is described here that the service identifier and the like are stored in correspondence with the communication / information processing node, the service flow information and the service related information such as the service identifier information are stored in the local cache memories 2 and 7. Aside
With the service request information as a key, the corresponding service flow information level library or the service identifier level library can be retrieved, and when the service flow information is selected, the service flow structure can be read,
The configuration may be such that when a service identifier is selected, a list of service parameters necessary for realizing the service identifier and communication / information processing nodes having the service identifier can be found. (P3) Next, the service origination node 1 registers the service flow information in the local cache memory 2, creates an active packet by setting the service flow information and data as a set, and originates the packet.
(F), The same operations and processes as the processes (A) to (D) are performed to provide the service to the service receiving node 6 (see FIG. 12).

At this time, the connection form when moving between adjacent nodes may be a CL type or a CO type. In the case of the CO type, the connection management node 8 sets the connection according to the connection setting request.

Further, in FIG. 13, without specifying the communication / information processing node that provides the processing, an active packet is suddenly transmitted to the network, various processing nodes are moved, and the communication / destination of the moving destination is moved. It is a figure which shows operation | movement of the 5th Example at the time of providing a desired communication and information processing service by sequentially performing a process in an information processing node. Here, the method shown in FIG. 13 and FIGS.
The difference between the methods shown in is that the method shown in FIGS.
In contrast to the method of grasping the processing node that provides the processing in advance and creating the active packet based on the service flow information in which the processing node that provides the processing is described, and providing the desired communication / information processing service. In the method shown in FIG. 13, even when the processing node that provides the processing is not known in advance, the desired communication / information is suddenly created by creating / transmitting the active packet and searching for the communication / information processing node that provides the processing. This is a method of realizing a processing service.

Next, the general operation of FIG. 14 will be described.

In this embodiment, a description will be added on the assumption that the layer 2 level communication protocol between adjacent nodes is secured.

Layer 2 level communication securing phase (1) First, the originating node checks the state information of the adjacent node (within the range of the number of hops M), and the adjacent node (for example, 90
a, 90b, 90c) status information (congestion, failure status, etc.)
The service processing node acquisition / execution phase is entered. (2) When returning from the service processing node acquisition / execution phase to the layer 2 level communication securing phase, the number of hops is increased from the originating node 1 within the processing range restriction area 90 (hop count = N) inside the packet to perform communication / The active packet is moved to any communication / information processing node for which the information processing service has not been executed yet, and the destination node becomes the proxy originator node and returns to (1).

If a node that can be processed is not found even if the number of hops reaches the upper limit, it means that the node cannot be processed, the process is terminated, and the route information stored in the transfer history information storage area is deleted. Based on this, the processing impossible notification is given to the start point node.

Service Processing Node Acquisition / Execution Phase Next, information indicating what kind of route should be transferred in order to realize a service in the state where layer 2 level communication between adjacent nodes is secured. Is the phase to acquire.

The transmission node 1 refers to the local cache memory 2 of its own node based on the service request information,
If the service flow information for realizing the service is registered, an active packet is created based on the read service flow information, etc., and the service execution phase is entered, and the service flow information is not registered. In this case, it is still unknown which communication / information processing node can obtain the desired communication / information processing service, but the service request information is interpreted and the service flow information, the end point node, and the like shown in FIG. The same active packet is created, and the service processing node acquisition / execution phase is started.

The operation of the service processing node acquisition phase is shown below. (1) First, the originating node sequentially or simultaneously sends active packets including service flow information to adjacent nodes, for example, 90a, 90b, 90c (through the communicable transmission path stored in the layer 2 level communication securing phase). Within the number of hops M). (2) The adjacent node that receives the packet checks the packet authentication and the services that can be provided by this communication / information processing node to realize the communication / information processing service that can be provided, and , The processing range, the node identification number, and the transmission path number are notified to the transmitting node. (3) The transmitting node, which has received the notification result from the adjacent node, grasps the execution range of the process, updates the service flow information, and if all requested services are not realized, layer 2 level communication is performed. Return to the securing phase (2).

If all the processing is completed, the packet is transferred to the end point node 6 and the intended processing is completed.

FIG. 13 shows a communication / information processing service request from a source node to a communication / information processing node within the range of the number of hops M, and a processing result executable by the communication / information processing node within the range. If the desired communication / information processing service has not been realized yet after acquisition, the same operation is repeated by using any communication / information processing node for which the communication / information processing service is not yet executed as the source node. However, as shown in FIG. 14, the active node is transferred from the transmission node to any one communication / information processing node (reception node) capable of transmission for the time being, and this communication / information processing node (reception node) After providing communication / information services that can be provided,
Using the information processing node as the originator node, move the active packet to any communication / information processing node (reception node) that is not stored in the transfer history information (has not been processed), repeat the same operation, and repeat When the communication / information processing service is completed, the processing result may be transferred to the end point node.

The active packet may be provided with time information or billing information as an effective period defining area, or may be provided with time stamp information for synchronization of communication / information processing or QOS guarantee. It may be configured to be possible.

In the first to fifth embodiments described above, the status information updating / notifying means 102, the communication / information processing change maintaining means 103, and the packet processing history recording means 104 are provided only on the control device 100 side. However, the present invention is not limited to this, and the state information updating / notifying means 102, the communication / information processing change maintaining means 103, and the processing history recording means 104 are used as the master side functions for communication. The information processing node 11 side may be provided with each unit as a unit that controls the slave function. That is, as in the communication / information processing control system according to the sixth embodiment shown in FIG. 17, the communication / information processing node 11a
State information update / notification means 202, communication / information processing change maintaining means 203, processing for analyzing communication control information and information processing control information in the active packet in the node to update communication processing and information processing The history recording means 204 may be provided. With such a configuration, it is possible to execute the transition of processing in the node by analyzing only the header information of the active packet.

[0099]

As described above, according to the present invention, (1) even if there is no data to be transmitted through the network, the communication line is provided until the processing between the own station node and the other station node is completed. It is inefficient to remain connected (2) With the increase of data transmission through the network,
The control of data transmission becomes extremely complicated, and the communication time for data transmission increases. (3) Since the progress and status of the processing could not be known after the active packet was sent, the result for the requested processing is difficult to return. If it does not come, it is not possible to make an appropriate decision as to what kind of action should be taken. (4) Since the communication / information processing contents could not be changed after the active packet was sent, the request was made. The processing cannot be continued even if the processing is terminated by the timer that defines the valid period and is not completed, or the processing cannot be canceled even if the user wants to cancel the processing request. (5) Within the active packet In addition, because the range of communication and information processing was not specified, the cause of system congestion by requesting more processing than necessary If the packet continues to be transferred indefinitely for some reason, it cannot be excluded from the system, and the transfer bandwidth of the system is squeezed. (6) A processing unit that can execute the requested processing Since the search result of the processing unit, which is performed when the user does not know where is, is not stored, for the same service request,
It is necessary to explore each executable processing unit, which is inefficient (7) If the user does not know can receive service from a pre what information providing or processing unit, information that satisfies the user's service requirements When there are many providing / processing units and the user obtains the desired information,
Problems such as enormous charges exceeding the user's expectation cannot be solved if only time is used to define the valid period of packet communication / information processing system. Can be resolved.

Further, by providing the time stamp information in the active packet, there is an effect that it can be used for communication / information processing synchronization and QOS guarantee. In addition, when an active packet is used, the packet can move autonomously in the communication network, and can request the destination node to instruct and execute the process. (1) Utilizing various nodes in the communication network Thus, there is an effect that it is possible to provide advanced communication / information processing services.

(2) The user can control the network within a certain limit.

Therefore, it is possible to provide a service that meets the needs.

(3) Since the user can download personal database information, control information, etc. in the network, the user can customize the network according to his or her preference.

It has the effect of.

In addition, the communication / information processing node has a function of converting active packets such as generation, discarding, division, multiplexing, etc., and the communication / information processing service executes a data flow (command which enables execution of all input data). Since it is processed based on the concept of (execution one after another), it has the effect that the speed-up effect of parallel processing can be expected.

Further, the active packet is supported by a part or all of middleware between the application and the OS, between the layer 4 and the OS, or between the layer 2 and the layer 3, and a uniform interface between the layers is provided. By doing so, it is possible to hide the difference between physical media and the difference between OSs, and it is possible to easily provide high-level services even in a multi-vendor or multi-network environment.

[0107] In addition, also need to know whether or not there is in advance what kind of databases, as in the conventional database search, with the effect that there is no need to remember how to issue commands for each database.

Further, since the service request for the active packet is in the form that the user simply specifies it by using the icon or the like, the user can easily specify his / her favorite service. have.

Further, the functions and management information of the centrally deployed service management node are distributed and deployed to any communication / information processing node (IWU such as exchange, router, gateway, etc.) or local host in the network. Therefore, the load on the service management node can be reduced.
