- the communication control unit 404 in FIG. 5 includes a flow table 507 and a flow state table 508 in addition to the routing table 510 that is used by a normal communication device for destination search. It manages a search key (search key) for distinguishing packets, a communication status (status), and application execution position information.
- the search key is subject to packet header information and, in some cases, packet payload information.
- the communication status (status) manages whether or not a connection is established, and allows the user to select a situation in which the connection is disconnected when the execution position is dynamically changed.

- the communication control unit 404 of the IN 102 in the system performs control to change the position of information processing for processing a packet. More specifically, the table updating unit 506 of the communication control unit 404 rewrites the interface in the flow state table 507 to change the MAC address of the L2 header added to the packet. For example, when the packet destination is forcibly changed to the server 1021-1 of the IN102 itself, the source MAC address 2011 is rewritten with eth0 in FIG. 4 and the destination MAC address 2010 is rewritten with eth4 which is the MAC address of the server 401-1. Thus, the packet can be transmitted to the server 401-1. Thus, the communication control unit 404 performs an information processing position changing function in the system in addition to the normal communication function.
- the optimal processing position in the network is not unchanged and changes from moment to moment according to the situation. This is due to the state of the network, the load status of the computing resources being used, or the movement of the physical space of the user itself.
- the information processing position is changed by the IN 102 under the instruction of the MN 103 by the configuration of the communication control unit 404 described above. That is, as described above, information processing that should have been originally executed by the DC 106 can be executed by the server function unit on the IN 102, or between the servers 401-1 to 401-3 in the own IN. It is also possible to change the information processing assignment or, conversely, to change the information processing from the own IN 102 to another IN 102 or DC 106.

It is assumed that the physical port of the IN 102 that has been set.
- the flow state table 508 is created by software, for example, a table is created on a memory in the communication control unit 404.
- the output destination determination unit 504 also refers to the normal routing table 510.
- the routing described in the flow state table 508 is prioritized instead of the routing by the routing table 510, so that the packet destination can be changed.
- the flow state table 508 may be provided in the memory in the server 401 of the server function unit.
- the destination that may change the destination is the output destination determination unit 504, which uses a normal policy-based routing function to select packets belonging to the corresponding flow regardless of the application break. Transfer to the corresponding server 401.
- the server 401 includes a flow state table 508 in terms of software and logic, where the packet is transferred as described in the flow state table. Since the server 401 normally operates by executing a program by the CPU, if there is a problem in speed, a dedicated hardware circuit can be installed in the server 404.
- the server 404 of the own IN receives a packet that is not addressed to its own IP address. Since this packet cannot be received if it is normal, it is set so that the destination IP address of the flow can be received in advance setting, that is, at a timing before setting to the self in the flow state table 508 Keep it.
- the source IP address is not the original IP address but the destination IP address of the flow.
- the output destination determination unit 504 sets the destination IP address of the input packet to the IP described in the new destination (new destination) 1105. It will be changed to an address. In this case, the output destination determination unit 504 once terminates communication and newly starts communication with a new destination (new destination) 1105. That is, the method using the new destination 1105 of the flow state table 508 terminates communication with the terminal once, performs new communication with the new destination, and as a result, the terminal communicates with the new destination. Become.
- the routing table 509 is also used in the system of this embodiment in order to determine the output destination of the packet from the IN 102. More specifically, if the communication control unit 404 finds that there is no registration as a result of searching the flow information table 508, the communication control unit 404 subsequently searches the routing table 509 as usual and next hop (next hop) indicating the output destination. ) And interface. Note that the communication control unit 404 may search the flow information table 508 and the routing table 509 in parallel. In this case, if there is registration in the flow information table 508, the output destination of the flow information table 508 is used preferentially.
- the communication control unit 404 is common in that the output destination from the IN 102 is determined. However, when using a routing table, the communication control unit 404 determines an output destination for a destination IP address according to a routing protocol such as OSPF (Open Shortest Path First) or BGP (Border Gateway Gateway Protocol). Is different in that the communication control unit 404 determines output destinations corresponding to a plurality of fields in the packet according to the instruction of the MN 103 and the load status of the server function unit of the IN 102. That is, by using the flow state table in the present embodiment, the communication control unit 404 changes the output destination in accordance with the flow state, and changes the server position where the application is executed, that is, the dynamic information processing position change described above. Do.
- OSPF Open Shortest Path First
- BGP Border Gateway Gateway Protocol
- FIG. 19 the blocks assigned the same numbers as those in the overall system configuration diagram of FIG.
- reference numeral 119 denotes an automatic door with a monitoring camera.
- camera video data is input to the first network node EN101 as indicated by an arrow 1901 from the automatic door 119 with a monitoring camera, and the face image is extracted by the above-described arithmetic function or filter function in EN101.
- the extracted face image data is sent to the second network node IN102 as indicated by an arrow 1902.
- IN 102 a part of the face image data DB is cached from the DC 106, the face match with the face image data extracted and transmitted from the EN 101 is confirmed using the data of the face image DB that is held, and it is determined as a match. If so, a door opening command is sent to EN 101 as indicated by arrow 1902. If they do not match, a command not to open the door is sent.
- the EN 101 Upon receiving the door opening command, the EN 101 generates a processing command for the door control device of the corresponding automatic door 119 with a monitoring camera, and feeds back the processing command with an arrow 1901.
- an arrow 1903 indicates that, for example, when the log of the execution result of IN102 is accumulated, or when the face image DB is requested and received when the face image DB to be detected for matching is insufficient, the matching check cannot be performed in IN102. 4 shows a case where the processing is requested to the DC 106 and the result is received.
- FIGS. 13 to 18 and FIGS. FIGS. 13, 14, and 15 show basic processing flows of EN101, IN102, and DC106, respectively.
- the EN 101 periodically checks the network interface for reception of packets from the sensors 107, actuators 108, terminals 109, IN102, etc. (step 1301, the steps are omitted in parentheses hereinafter).
- packet content analysis is performed (1302).
- the packet content is information from various information sources such as the sensors 107 (1303), and in the case of information from various information sources (YES, hereinafter omitted), the data is held (1304). Then, necessary arithmetic processing (1305), filter processing (1306), and aggregation processing (1307) are sequentially executed on the retained data.
- necessary arithmetic processing (1305), filter processing (1306), and aggregation processing (1307) are sequentially executed on the retained data.
- face authentication automatic door system when an image data packet is received from a surveillance camera, it is determined as information from various information sources, and a face image extraction process is performed.
- step 1303 If it is determined in step 1303 that the packet content is not information from the information source (NO, hereinafter omitted), it is determined whether the packet content is feedback information from the upper IN 102 or the like (1310). In the case of feedback information, the EN 101 generates a processing command (1311). It should be noted that the processing command is generated in the same manner even when a negative determination is made in step 1308. The generated processing command is transmitted as a packet to the processing target (1312). In the case of the above-described service, for example, information such as “open the door” is received as the feedback information, and a processing command for the door control device is generated.
- step 1310 If it is determined in step 1310 that the information is not feedback information, it is subsequently determined whether or not the command content is a stored data request (1320). In the case of a request for data stored in the EN 101, the corresponding data packet is transmitted to the request destination (1321). If the request is not a stored data request, if the request can be handled by EN 101, the request is executed (1330).
- the IN 102 periodically checks whether the network interface has received packets from the subordinate EN 101, terminals 109, DC 106, etc. (1401), and performs packet destination analysis when a packet is received (1401). 1402). Then, it is determined whether or not it is a packet destination target (1403), and in the case of a packet whose destination is to be changed, it is determined whether or not the destination is its own node (1404). Transfer the packet to. If the packet is not a destination change target packet, normal routing is performed (1450). If the changed destination is other than the local node, routing is performed to the designated destination (1460).
- the packet shown in FIG. The destination is analyzed by referring to one or more fields of the field, and if specified, the contents of the flow combining the payloads of a plurality of packets.
- the packet is transferred to a destination different from the destination IP address described in the packet, for example, a server function unit in the own IN.
- the destination change target in step 1403 means that the packet is described in the flow state table 508 and determines the destination by looking at information other than the destination IP address. Further, the designated destination is not the destination IP address but the meaning of the description destination in the flow state table 508.
- face information is extracted as necessary information processing, and when it matches the stored or cached face image DB, a command to open the door is generated, and EN 101 is compared with the processing in DC. Feedback with less delay. If they do not match, the command that cannot open the door is fed back. Further, the control content such as to which target person the door has been opened is notified to the DC 106.
- information processing for example, analysis / detection of whether there is a companion is also performed, and when a companion is detected, an alarm is notified to a destination such as an individual or a DC registered in advance.
- step 1407 If it is determined in step 1407 that data outside the own IN 102 is necessary, it is determined whether the process can be processed in the own IN (1408), and if it is determined that the process is possible, the necessary data is requested (1409).
- data arrives (1410) information processing is performed to generate a result (1411). If it is determined that the process cannot be performed by the own IN, the process is transferred to the original destination before the change (1470).
- the face image DB to be checked for coincidence is insufficient, the face image DB is requested to the DC 106, the face image DB is obtained, and the above-described information processing is continued. Further, if the face image DB to be matched is insufficient and the face image DB is not transferred by the DC 103 or the like, the processing is requested to the DC 103 if the matching inspection cannot be performed.
- the DC 106 periodically checks whether there is no packet received from the IN 102 via the network (1501), and if a packet is received, performs packet content analysis (1502). As a result, it is determined whether or not the content is a transfer request for stored data (1503). If it is not a transfer request, it is determined whether or not it is a data storage request (1504). If the content is a data transfer request, the target data is transferred (1550). For example, in the previous service example, since the DC 106 holds all the face image DBs, the face image data that may match is transferred to the IN 102. If the content is a data storage request, the received data is stored (1560).
- processing is executed (1509).
- information processing such as a test for matching with face image data in the stored face image DB is executed.
- a data request is made (1507), and when data arrives, information processing is performed in the same manner.
- the information processing result is fed back (1510) and log accumulation is performed (1511). That is, when the face image and the face image DB match, a command to open the door is fed back via IN102 and EN101, and the fed back information is stored in a log.

- the management information resetting is started when the processor reads the management information setting program 610 and the management table 607 stored in the storage device 605 of the MN 103 when there is a management request in the check (1700) of whether there is a management request.
- the processor executes a management information setting program, performs resetting by new registration or deletion, creates setting information, and updates the management table. That is, a user having management authority such as an ISP (Internet Service Provider) or a corporate information management department makes a registration request or a deletion request for an application to be used as a management request to the MN 103 of this system. In this request, the service level can also be specified as an option.

- information processing is started in the vicinity of the sensors 107 that are information generation sources.
- step 1701 If a registration deletion request is made in step 1701, the corresponding user is deleted from the table, and the MN 103 distributes and applies the information. If it is determined in step 1701 that the request is not a registration request or a deletion request, it is determined whether or not it is a recalculation request (1704). If it is a resetting request, setting information is regenerated (1705). If it is not a recalculation request in step 1704, management processing is executed (1710).
- FIG. 18 shows an example of a processing flow for resetting management information in EN 101 and IN 102 based on an instruction from MN 103.
- the resetting means that the management request is not a request from a user or the like but is set based on information obtained by monitoring the status of IN102 or EN101.
- the MN 103 recalculates various information to be managed, and generates new setting information. As a result, if it is necessary to distribute the application to specific IN and EN, distribution is performed. In addition, if there is a change in various setting information regardless of whether or not the application is distributed, it is notified to IN and EN.
- the IN 102 is requested to add a new information processing request to the flow state table, the information processing position is explicitly returned to the DC 106, moved to another IN 102, and an algorithm for these is notified. And so on. After this notification, a command is issued to actually reflect the setting. This recalculation itself may be left to the management server 401-4 on the IN102.
- EN 101 checks whether or not control information is received (1801), and if control information is received, determines whether or not the control information is an application program (1802). If it is an application program, the program is installed (1803). If it is not an application program, it is determined whether the control information is setting information (1811). If it is setting information, preparation for applying the setting information is performed (1812). Further, it is determined whether or not the control information is a setting validation request (1821). If the control information is a setting validation request, the setting information is applied (1822). On the other hand, if the request is not a setting validation request, if the control information is a request that can be dealt with, it is executed (1831).
- the control information processed here is information such as notification of a processing method when a failure occurs.

Abstract
Description
前記第一のネットワークノードで、前記端末から取得した情報を用いて、前記情報処理装置を宛先とするパケットを前記第一のネットワークへ送出し、前記第二のネットワークノードで、前記第一のネットワークから前記パケットを受けた場合、前記パケットに含まれる宛先及び情報に基づいて、前記第二のネットワークノードが有する情報処理機能部または前記第二のネットワークノード以外のノードに前記パケットを出力し、前記第二のネットワークノードで、前記情報処理機能部による前記パケットに対する処理結果を含むパケットを、前記第一のネットワークノードに送信し、
前記第一のネットワークノードで、前記処理結果を含むパケットを受信し、前記端末に前記サービスを提供する、ことを特徴とする情報通信処理方法である。
、情報通信処理方法を提供する。
処理コマンドを生成することになる。
IN102であれば、自身の配下のEN101とIN102自身の状態を収集し(1601、1602)、予め定められた時間が経過するか、例えば新規のEN101が追加、除外、或いはIN内部にサーバブレードの追加、削除があったなどの特定のイベントが発生した場合に、モニタ情報を上位の管理機構であるMN103に通知する。(1603、1604)
MN103であれば、自身の配下のIN102とMN103自身の状態を収集し(1601、1602)、予め定められた時間が経過するか、例えば、新規のIN102が追加された、除外された、ダウンした、或いは本システムに対する新規の情報処理要求登録があった、削除されたなどの特定のイベントが発生した場合に、情報処理の割当先を変更したほうがよい可能性があるため、再計算要求を出す。(1603、1604)
図17は、MN103における管理情報再設定フローの一例を示している。管理情報の再設定は、管理要求の有無のチェック(1700)で管理要求有の場合に、MN103の記憶装置605に格納されている管理情報設定プログラム610と管理テーブル607をプロセッサが、読み出し、開始する。例えば、プロセッサは、管理情報設定プログラムを実行し、新規登録や削除による再設定を行い、設定情報を作成、管理テーブルを更新する。すなわち、ISP(Internet Service Provider)や企業の情報管理部門など、管理権限のあるユーザが、本システムのMN103に対する管理要求として、利用したいアプリケーションに対する登録要求や削除要求を行う。この要求の際に、そのオプションとして、サービスレベルも指定することもできる。例えば、対象となるアプリケーションの特定の動作に関して、応答速度要求を100ms以内、応答速度要求を500ms以内、応答速度要求を1s以内、などのサービスレベルを指定することができる。以下、一例として新規登録を例に取り説明する。
SIPが該当ユーザ、場合によっては、該当ユーザを収容するEN101、
DIPが該当アプリケーションAの当初宛先IP1(DC#1))、
SPORTが該当ユーザアプリケーションを示すポート番号、
DPORTが該当アプリケーションを示すポート番号、
PROTOCOLがTCP
とすることができる。
アラーム配信先を登録宛先として収容しているEN101は、IN102からアラーム通知が来た場合に、アラーム配信先に適したフォーマットを生成して配信する。これは、図13のフローチャートで1301→1302→1303→1310→1311→1312と遷移する内容に相当する。
