Below, with reference to accompanying drawing, execution mode of the present invention is described.
(A: structure)
Fig. 1 is that a execution mode that expression comprises electronic equipment of the present invention is relay 30A and the 30B figure in the structure example of interior communication system 1.This communication system 1 is LAN in the site of for example in each site of enterprise, setting up (in Fig. 1 for the site in LAN 20A and 20B) to be connected with common wide area network 10 constitute.Common wide area network 10 is the Internet for example, is by the common communication network that utilizes of nonspecific many people.As shown in Figure 1, on common wide area network 10, be connected with sip server 40.As noted above, sip server 40 is that " SIP URI " and IP address are stored as positional information in couples, uses this positional information to carry out the computer installation of relaying based on the communication information of SIP transmission/reception.For this sip server 40, has no difference owing to comparing, so detailed with existing SIP server.
LAN 20A is connected with common wide area network 10 via relay 30A in the site, and LAN 20B is connected with common wide area network 10 via relay 30B in the site.Relay 30A and 30B for example are routers, are assigned with intrinsic IP address respectively.In this execution mode, relay 30A has identical structure with 30B.Therefore, below under situation about need not distinguish separately to relay 30A and 30B, be expressed as " relay 30 ".Relay 30 to LAN connected in the site as its linking objective communicator and other communicators (for example has; The communicator that is connected with common wide area network 10 or with other sites in the communicator that is connected of LAN) between, the data packet communication that carries out according to IP is carried out the function of relaying.In addition, relay 30A and 30B have been assigned with intrinsic " SIP URI " respectively, also have according to based on the step of SIP and and set up the function of communication session between other communicators.And (record) logined in sip server 40 as positional information in couples in the IP address that will be somebody's turn to do " SIP URI " and distribute to relay 30.
In the site, be connected with operating terminal 50 on the LAN 20A.This operating terminal 50 for example is a personal computer, and the telnet client-side program is installed in advance.So-called telnet client-side program is the program that is used to realize Telnet (telnet connection).The user interface that the user of operating terminal 50 is provided via the telnet client-side program can be carried out the various command of sending to this electronic equipment as the appointment of the electronic equipment of Telnet target (for example the IP address of assigning remote login target etc.) and input.The orders of importing as stated etc. are sent to the electronic equipment as its linking objective via telnet.In this execution mode, through utilizing this telnet client-side program Telnet, and send action and set the order of usefulness (below be called action set), thereby the long-range action that realizes relay 30 is set with order to relay 30.In addition, also can operating terminal 50 is connected in series with relay 30A, carry out the telnet client-side program on the relay 30A and carry out telnet with relay 30B and be connected.In addition; In Fig. 1, example shows the situation that LAN 20A is connected in 1 operating terminal 50 and the site, but LAN 20A also can also be connected with a plurality of communicators in the site except operating terminal 50; Identical ground, LAN 20B also can be connected with a plurality of communicators in the site.
In this execution mode; The user of operating terminal 50 is for belonging to (that is, being connected in the same site on the LAN 20A) relay 30A of the same network segment with operating terminal 50, known in advance " SIP URI " and IP address the two; But for relay 30B, only known " SIP URI ".Therefore, the user of operating terminal 50 can't carry out telnet with relay 30B with operating terminal 50 and be connected, and looks that the long-range action that can't carry out relay 30B sets.But relay 30 constitutes, even the IP address insufficient is set as long as known " SIP URI " just can carry out long-range action, this point is the characteristic of this execution mode.Below, be that relay 30 is that the center describes with the characteristic of this execution mode.
Fig. 2 is the block diagram of the structure example of expression relay 30.
Bus 360 as shown in Figure 2, that relay 30 comprises the 320, the 2nd communication I/F portion 330 of control part the 310, the 1st communication interface (below be called I/F) portion, external equipment I/F portion 340, storage part 350 and the data transmission/reception between above-mentioned inscape carried out relaying.
Control part 310 for example is CPU (Central Processing Unit).This control part 310 is through carrying out program stored (firmware) in the storage part 350 (more precisely, being non-volatile memories portion 354), thereby realizes the each several part of relay 30 is concentrated the effect of control unit of control of moving.For the detailed content of control part 310, clearly record and narrate in the back according to the performed processing of firmware.
The I/F portion 330 that communicates by letter with the 2nd of the 1st communication I/F portion 320 is NIC (Network Interface Card), respectively with different communication network connections.Specifically, the 2nd communication I/F portion 330 all is connected with common wide area network 10 in relay 30A and 30B.On the other hand, LAN 20A is connected in the 1st communication I/F portion 320 of relay 30A and the site, and the 1st of relay 30B communicates by letter, and LAN 20B is connected in I/F portion 320 and the site.The 1st communication I/F portion 320 packet that I/F portion 330 will receive from linking objective communication network separately of communicating by letter with the 2nd (is cut apart communication information with predetermined data size; And the communication information after cutting apart added the predetermined data head respectively and the data block that obtains) send to control part 310, and will see off to linking objective communication network separately from the packet that control part 310 sends.Promptly; The effect that the 1st communication I/F portion 320 realizes via the communication unit of transmission/receptions that communicates message as LAN in the site of its linking objective, 330 realizations of the 2nd communication I/F portion communicate the effect of communication unit of the transmission/reception of message via common wide area network 10.
External equipment I/F portion 340 be with external equipments such as exterior storage medium (for example, USB (Universal Serial Bus) memory etc.) or serial console between according to the rules agreement (USB or RS-232C) carry out the aggregate of the interface of data transmission/reception.For example; Using under the situation of USB storage as external equipment; Comprise USB interface as long as make in the external equipment I/F portion 340, using under the situation of serial console, as long as make serial line interfaces such as comprising the RS-232C interface in the external equipment I/F portion 340 as external equipment.Under the blind situation of the IP of relay 30B; In the prior art; Connect serial console and the setting of moving in the external apparatus I/F portion 340; But in this execution mode, can be the data communication that common wide area network 10 carries out through the linking objective via the 2nd communication I/F portion 330, (being that long-range action is set) be set in the action of carrying out relay 30B.
Storage part 350 comprises volatile storage portion 352 and non-volatile memories portion 354.Volatile storage portion 352 is RAM volatile memory such as (Random Access Memory) for example, the working region when being used as control part 310 and carrying out firmwares.In addition, store session admin table also in volatile storage portion 352, wherein login have and relay 30 between set up the mailing address of the electronic equipment of communication session.For in this session management table, communicating the login of address and the timing of deletion (timing), in the action example, clearly record and narrate.
Non-volatile memories portion 354 is EPROM nonvolatile memories such as (Erasable Programmable Read Only Memory) for example.In this non-volatile memories portion 354, except firmware, also store various data in advance.As an example that is stored in the data in the non-volatile memories portion 354, as shown in Figure 2, can enumerate action regulation parameter.So-called action regulation parameter is the parameter of the intrinsic action of regulation relay 30.In the action regulation parameter of this execution mode, comprise: the parameter (omitting diagram) and the long-range action of the action that regulation relay 30 carries out as relay (that is the action during, relaying data packets is handled) are set and could be indicated.
For example; As predetermined parameter is carried out in the intrinsic action in the packet relay process; Can enumerate the parameter (parameter of for example, in coded communication, using) used in linking objective address and this connection of VPN, confirm as the parameter of the packet of filtering object etc.Above-mentioned parameter also is called as configuration of routers.Through rewriting this configuration of routers, can change the performed relaying data packets processing action of relay 30.On the other hand; Long-range action is set could indicate it is that boolean's data are (in this execution mode; Be data with any value in " 1 " or " 0 "), if being worth, this is " 1 ", then expression allows to carry out long-range action setting; Be " 0 " if this is worth, then expression does not allow to carry out long-range action setting.Set and to indicate for this long-range action; Also can when the factory shipment of relay 30, be set to " 1 " or " 0 " in advance; Accordingly this value is rewritten with the indication of sending from the serial console that is connected in the external equipment I/F portion 340; Perhaps, set through long-range action and this value is rewritten.Through should be long-range action set and could indicate from " 0 " and be rewritten as " 1 " (or be rewritten as " 0 " from " 1 "), thereby change is carried out the relevant setting of long-range action setting with whether permitting.In addition; In this execution mode; In action regulation parameter, comprised long-range action and set sign, but also can only configuration of routers have been stipulated parameter as action, outside this action regulation parameter, separately sign has been set in long-range action and be stored in the non-volatile memories portion 354.
The firmware of storage is as shown in Figure 2 in the non-volatile memories portion 354, is to be used to make control part 310 to carry out packet relay process, communication session management processing and action set the program of handling.If connect the power supply (omitting diagram) of relay 30, then control part 310 reads out to above-mentioned firmware the volatile storage portion 352 from non-volatile memories portion 354, and begins to carry out this firmware.Relaying data packets by control part 310 is carried out according to firmware is handled, and is the processing of the intrinsic actions of router such as relaying of carrying out foundation and the packet of VPN according to action regulation parameter.Handle for this relaying data packets, owing to have no difference with processing in the common relay, so detailed.
Fig. 3 is the flow chart of the flow process handled of communication session management that expression control part 310 is carried out according to firmware, and Fig. 4 is the flow chart that the flow process of handling is set in action that expression control part 310 is carried out according to this firmware.Communication session management handle be from other electronic equipments to set up based on the steps request of SIP under the situation of communication session, confirm the processing that could set up communication session.On the other hand; So-called action is set to handle and is meant; Under situation about connecting from other electronic equipment requests telnet, confirm to carry out telnet and connect, and under the situation that permission telnet connects; Action according to the electronic equipment from the linking objective that connects as telnet sends is set with order, and action regulation parameter is rewritten.This execution mode is characterised in that above-mentioned communication session management is handled and processing is set in action.For the detailed content that above-mentioned communication session management is handled and the action setting is handled, in the action example, clearly record and narrate for fear of repetition.
It more than is the structure of relay 30.

Below, the operation management personnel of communication system 1 are operated operating terminal 50 and relay 30B is moved situation about setting as an example, the action of relay 30 is described.In addition, in the action example of following explanation, " the SIP URI " that distribute to relay 30A is made as sip:xxxaaa, " the SIP URI " that distribute to relay 30B is made as sip:yyybbb.
(B-1 :) in the action that is set under the situation that allows the long-range action setting of execution
The value that at first, could indicate the long-range action setting of storing in the non-volatile memories portion 354 of relay 30B is that the situation of " 1 " describes.Operating terminal 50 is operated and will be carried out the user that the action of relay 30B is set, at first on operating terminal 50, start the telnet client-side program, Telnet is to relay 30A.Then, 30A sends indication to relay, and its content is for setting for the electronic equipment of sip:yyybbb (being relay 30B) carries out long-range action " SIP URI ".In addition, in this action example, Telnet has been described to relay 30A and send the situation of content for the indication relay 30B being carried out long-range action and set, but can certainly operating terminal 50 is connected in series and send this indication with relay 30A.
Fig. 5 is the figure of an example of the communication sequential in the expression communication system 1.Receive content and be the control part 310 of the relay 30A that carries out the indication that above-mentioned long-range action sets; Generation will be set up request message (Fig. 5: INVITE), in its source body portion, write and be intended to ask to allow to carry out identifier (in this action example, being " remote setup " this character string) and the transmission that long-range action is set as the communication session of setting up target of communication session by " SIP URI " (being sip:yyybbb) of user's indication.Like this, it is as shown in Figure 5 to set up request message from the communication session of relay 30A transmission, is received by sip server 40.In addition; In above-mentioned communication session is set up the source body portion of request message, write the distinctive identifier of this execution mode, but above-mentioned identifier has been write the change that neither belongs to message format in the source body portion, in addition; Do not belong to yet and append new traffic message (that is, not belonging to the expansion of SIP).Therefore, the communication session that in source body portion, writes above-mentioned identifier is set up request message and can in sip server 40, do not gone out of use.
As shown in Figure 5, if receiving above-mentioned communication session, sip server 40 sets up request message, then to relay 30A loopback communication information (Fig. 5: " 100 Trying "), notice is asked corresponding processing this situation just in commission with this.Then; Sip server 40 is with reference to the positional information of login in this device; Confirm to set up " SIP URI " corresponding IP address of setting up target of being appointed as communication session in the request message, and be that target is passed on above-mentioned communication session and set up request message with this IP address with above-mentioned communication session.Thus, above-mentioned communication session being set up request message passes on to relay 30B.If the control part 310 of relay 30B receives above-mentioned communication session via the 2nd communication I/F portion 330 and sets up request message; Then loopback communication information (Fig. 5: " 100 Trying ") is asked corresponding processing this situation just in commission with notice and this, and the executive communication session management is handled.
Fig. 3 is the flow chart of the flow process of expression communication session management processing.As shown in Figure 3, whether the control part 310 of relay 30B is at first set up request message to the communication session that receives is that request allows the long-range action setting of execution to judge (step SA100) when communication session is set up in request.Specifically, the source body portion that 310 pairs of communication sessions that receive of control part are set up request message resolves, and judges the identifier (in this execution mode, being " remote setup " this character string) that whether writes regulation.Writing under the situation of this identifier, control part 310 is judged to be this communication session and sets up the message that request message is the long-range action setting of request permission execution.
Result of determination at step SA100 is under the situation of " denying "; If relay 30 has the functions relevant with audio communication such as voice over ip feature, then control part 310 is carried out and is received common communication session and set up identical processing (Fig. 3: common SIP processing) (step SA110) of situation of request message.For example be following processing, that is, make demonstration such as display unit represent communication session to set up the identifier in the transmission source of request message (for example being " SIP URI "), could set up communication session to user's query.On the other hand, in the result of determination of step SA100 under the situation of " being ", the later processing of control part 310 execution in step SA120.As noted above, in this action example, set up the source body portion of request message at the communication session that sends from relay 30A, write the identifier of regulation.Therefore, the result of determination of step SA100 is " being ", the processing that execution in step SA120 is later.
Whether the processing of step SA120 is to be confirmed to be set at by control part 310 to allow to carry out the processing that long-range action is set.Specifically, if the value that the long-range action setting of storage could indicate in the non-volatile memories portion 354 is " 1 ", then control part 310 is judged to be to set for and allows the long-range action of execution to set.On the contrary, be " 0 " if the value that could indicate is set in long-range action, then control part 310 is judged to be to set for and does not allow to carry out long-range action setting.Result of determination at step SA120 is under the situation of " denying ", and control part 310 loopback contents finish this communication session management and handle for refusing to set up the refusal response message (for example being 406 Not Acceptable) (step SA130) of communication session.On the contrary, in the result of determination of step SA120 under the situation of " being ", the processing that execution in step SA140 is later.In this action example, because the value that the long-range action setting of storage could indicate in the non-volatile memories portion 354 of relay 30B is " 1 ", so the result of determination of step SA120 is " being ", the processing that execution in step SA140 is later.
The processing of step SA140 is that the loopback content is the processing of the permission response message (Fig. 5: " 200OK ") that allows to set up communication session.When this permission response message of loopback, the port numbers that the control part 310 of relay 30B will be distributed to the IP address of this device and accept the COM1 that telnet connects writes back loopback in the source body portion with textual form according to SDP (Session Descript Protocol).Then, if the control part of relay 30B 310 is accomplished the transmission of above-mentioned permission response message, then wait for affirmation response (being the ACK) (Fig. 3: step SA150) that receives from the transmission target loopback of permission response message.In addition, be under the situation of so-called well-known port (well-known ports) at the COM1 of accepting the telnet connection, can omit its port numbers.
According to the permission response message that aforesaid way sends from relay 30B, as shown in Figure 5, arrive relay 30A through sip server 40.Receive the control part 310 of the relay 30A of this permission response message; IP address and port numbers in the source body portion that is written in this permission response message are read; Store as the long-range action target setting information of representing long-range action target setting; And the user of Telnet to the relay 30A to using operating terminal 50, the report communication session has been set up this situation.Then, control part 310 loopbacks of relay 30A with the IP address that comprises in the long-range action target setting information as sending destination address and with the IP address of this device affirmation response (Fig. 5: ACK) as transmission source address.Like this, from the affirmation of relay 30A loopback response, in common wide area network 10, suitably carried out route and arrived relay 30B.If the control part 310 of relay 30B receives above-mentioned affirmation response (Fig. 3: step SA 150; Be); Then this transmission source address is logined (Fig. 3: step SA160), finish this communication session management and handle in the session management table as the mailing address of setting up target of representing communication session.
If the user of operating terminal 50 has confirmed that according to above-mentioned report the communication session between relay 30A and the relay 30B set up this situation; Then send indication, the linking objective shown in the long-range action target setting information is carried out telnet connect to relay 30A.The control part 310 that receives the relay 30A of above-mentioned indication generates the communication information that contents connect for request telnet, and is that target is sent with IP address shown in the above-mentioned long-range action target setting information and port numbers.In this communication information, write the mailing address of relay 30A as transmission source address, write the mailing address shown in the above-mentioned long-range action target setting information as sending destination address.Like this, the communication information that sends from relay 30A is suitably carried out route in common wide area network 10, need not just to arrive the electronic equipment (being relay 30B) with above-mentioned long-range action target setting address via sip server 40.
Fig. 4 is illustrated in to receive under the situation of foregoing for the communication information of request telnet connection, and the flow chart of the flow process of handling is set in the control part 310 performed actions of relay 30B.As shown in Figure 4, control part 310 at first to and the transmission source of above-mentioned communication information between whether set up communication session and judged (step SB100).Specifically; Logined under the situation in the session management table at the transmission source address of above-mentioned communication information; Control part 310 be judged to be and the transmission source of above-mentioned communication information between set up communication session; On the contrary, do not have not to be judged to be and between the above-mentioned transmission source and to set up communication session under the situation of login in the session management table at above-mentioned transmission source address.
As shown in Figure 4, control part 310 is under the situation of " being " in the result of determination of step SB100 only, telnet is carried out in the transmission source of above-mentioned communication information connect (step SB110), then, carries out the order of sending from this linking objective.As noted above, from relay 30A to the moment that relay 30B has sent above-mentioned communication information, the mailing address of relay 30A has been logined in the session management table of relay 30B.Therefore, in this action example, the result of determination of step SB 100 becomes " being ", the processing of execution in step SB110.Then, the user of operating terminal 50 sends with order the exercises setting via relay 30A to relay 30B, makes the control part 310 of relay 30B carry out explanation and the execution of these action settings with order.Thus, the action regulation parameter of relay 30B is set with order according to above-mentioned action and is rewritten, and realizes that the long-range action of relay 30B is set.
In addition, if the long-range action of relay 30B is set accomplish, then the user of operating terminal 50 sends to relay 30A and cuts off the indication that telnet connects, and, send the indication of cutting off communication session to relay 30A.Like this, the control part of relay 30A 310 generates communication session that contents cut off communication session for notice and cuts off notification message (Fig. 5: BYE), and send to relay 30B.If the control part 310 of relay 30B receives above-mentioned communication session and cuts off notification message; Then response (Fig. 5: ACK) is confirmed in loopback; And the transmission source address that above-mentioned communication session is cut off notification message is from the session management list deletion, thereby accomplishes the cut-out of communication session.
More than be in the action example that is set to relay 30B under the situation that allows the long-range action setting of execution.
(B-2: be set at the action that does not allow to carry out under the situation that long-range action sets)
Below, the long-range action of storage in the non-volatile memories portion 354 of relay 30B set the value that could indicate and describe for the situation of " 0 ".Setting the value that could indicate in long-range action is under the situation of " 0 "; Set up request message even send the communication session that source body portion, has write the regulation identifier from relay 30A; The result of determination of above-mentioned steps SA120 also becomes " denying ", refuses response message (with reference to Fig. 6) from relay 30B to relay 30A loopback.Therefore, between relay 30A and relay 30B, do not set up communication session, do not notify the IP address of relay 30B yet to relay 30A.And,, in the session management table of relay 30B, do not login the IP address of relay 30A owing to do not set up communication session yet.
Here, the user who supposes operating terminal 50 is through obtaining the IP address of relay 30B someway wrongly, and telnet is attempted carrying out in this IP address connects as sending destination address.Even the telnet that attempts wrongly as noted above connects, also owing to the mailing address of in the session management table of relay 30B, not logining relay 30A, so the result of determination of above-mentioned step SB100 becomes " denying ".Therefore, can not make relay 30A and relay 30B carry out telnet and be connected, can not carry out the action setting of relay 30B via relay 30A.As noted above, if being set the value that could indicate, long-range action is made as " 0 ", then can between relay 30A and relay 30B, not set up communication session; Owing to permitting telnet to connect as condition to set up this situation of communication session; Even, also can prevent following situation reliably, promptly so obtain the IP address of relay 30B wrongly; Through utilizing this IP address to carry out being connected, carry out long-range action and set with the wrongful telnet of relay 30B.
Shown in as described above; According to this execution mode, set the relay 30 that the value that could indicate is set at " 1 " for long-range action, even its IP address insufficient; Also can in the process of setting up communication session based on the step of SIP, obtain the IP address, carry out long-range action and set.In addition; In this execution mode; Through writing the identifier of regulation in the source body portion that sets up request message at communication session; Thereby show it is the foundation request that is used for the communication session that long-range action sets, in source body portion, write data conditions and append newer command or change message format different, do not expand SIP.That is,, need not to carry out the SIP expansion and just can carry out long-range action setting the blind relay of IP according to this execution mode.
(C: distortion)
More than an embodiment of the invention are illustrated, but can certainly apply the distortion of the following stated.
(1) in the above-described embodiment; Explained from operating terminal 50 Telnet relay 30A; This relay 30A is operated and carries out the situation that the long-range action of relay 30B sets (that is, operating terminal 50 and relay 30A are as being used for that relay 30B is moved the acting situation of setting of operating terminal).But, also can directly with based on the step of SIP and from operating terminal 50 after relay 30B has set up communication session, carry out telnet and connect and implement above-mentioned long-range action and set.
(2) in the above-described embodiment, the situation during the action that is applied to router to the present invention is set is illustrated, but can certainly in the action of gateway apparatus is set, use the present invention.In addition, application of the present invention is not limited to the action of relays such as router or gateway apparatus and sets, and also can be applied to the action setting that Web server, application server etc. are positioned at the communicator and the so-called information household appliances of endpoint node.Importantly; So long as have the function of carrying out based on the intrinsic action of action regulation parameter; And electronic equipment with the function that communicates with the function of setting up communication session based on the step of SIP and based on telnet; In its action setting (that is the rewriting of the parameter of action regulation), just can use the present invention.
(3) in the above-described embodiment, used SIP as being used to set up the communication protocol of communication session, but also can use other session control protocols.Importantly, so long as can get final product setting up in the process of communication session to the session control protocol of setting up the mailing address (for example IP address) that target obtains the next protocol layer.In addition, in the above-described embodiment, as be used to move the order transmission/reception set communication protocol and used telnet, but also can use other communication protocols.For example also can utilize the POST method of HTTP (HyperText Transfer Protocol), action setting command that transmission should be carried out and the parameter that should set.
(4) in the above-described embodiment, set up communication session with step based on SIP, only limit to set up this communication session during, allow the target of setting up of this communication session is carried out telnet and connected, set thereby carry out long-range action.In this mode, can it be 1 also, with the conflict of avoiding long-range action to set with setting up the restricted number that long-range action sets the operating terminal of the communication session that uses with relay 30.Specifically; As long as to having set up under the situation of foundation request that relay 30 that long-range action sets the communication session of usefulness sends the communication session that long-range action sets usefulness once more, the control part 310 of this relay 30 is carried out refuse this processing of response message to get final product to the request source loopback unconditionally of this foundations request.In addition; Also can be to allow to set up the mode that the communication session of usefulness is set in long-range action with a plurality of operating terminals; But in this mode, control part 310 was carried out from the moment of having set up communication session begun processing through this communication session of timing turning off behind the certain hour.This is in order to tackle the attack of similar so-called SYN overflow.
So-called SYN overflow is the weakness that the step that establishes a communications link among a kind of TCP of utilization is promptly shaken hands for 3 times, communicator is absorbed in can't move the attack method of this state.Attack method as the similar SYN overflow of carrying out to relay 30; There is following method: set up communication session to relay 30 requests; Even this foundation is accomplished; Do not carry out that telnet connects yet but place and pay no attention to, then, the mailing address at alter operation terminal and continue request and set up communication session.Set up in the mode of the communication session that long-range action sets usefulness with a plurality of operating terminals allowing; If not having, relay 30 do not beginning function through this communication session of timing turning off behind the certain hour from setting up communication session; Then under the situation of the attack of this relay 30 being carried out similar SYN overflow; In the session management table, continue to append the mailing address of setting up target of logging on communication session, finally cause and overflow and can't move.Relative therewith; Beginning function if be provided with from setting up communication session through the timing turning off communication session behind the certain hour; Even then carried out the attack of similar SYN overflow, the mailing address of login in the session management table also can begin through being deleted behind the certain hour, therefore in its login; Can not produce above-mentioned overflowing, can not cause and to move.
(5) in the above-described embodiment, setting the value that could indicate in long-range action is under the situation of " 1 ", unconditionally to control part 310 loopback permission response message.But; Also can form; Even in receiving source body portion, writing the communication session of regulation identifier sets up request message and long-range action and sets the value that could indicate under the situation of " 1 "; Also the message of loopback permission response unconditionally not is under the situation of sending from predetermined electronic equipment but only set up request message at this communication session, just loopback permission response message.Specifically; The IP address (perhaps " SIP URI ") that login can be carried out the electronic equipment of long-range action setting to relay 30B in relay 30B in advance; The transmission source address of only setting up request message at the communication session that receives is under the situation of above-mentioned IP address (perhaps " SIP URI "), just makes control part 310 carry out the processing of loopback permission response message.
In addition; Also can be only under situation about connecting from communicator request telnet with predetermined mailing address; Just allow and to connect, in this mode, also can form; And whether set up communication session between this telnet connection requests source, all allowed to carry out telnet and connect.Its reason is, in this mode, because the request source that long-range action is set is by restriction in advance, so it is less to carry out the possibility that wrongful long-range action sets.In addition; The concrete grammar of logining in advance as the communicator that will allow telnet to connect; Existence will allow the mailing address of the communicator that telnet connects to be stored in the mode in the non-volatile memories portion 354 in advance, or the mailing address that will set up the communicator of 1 communication session at least is stored in the mode in the non-volatile memories portion 354 etc.
(6) in the above-described embodiment; The user of operating terminal 50 operates and logins to relay 30A this operating terminal 50; The relay that to set object as long-range action is (in above-mentioned action example; Be relay 30B) " SIP URI " be sent to relay 30A; With based on after setting up communication session between the step of SIP and the relay 30B, use and set up IP address and the port numbers of the relay 30B that obtains in the process at this, the Telnet action of carrying out relay 30B to this relay 30B is set separately; After end is set in this action, send the indication of cutting off the telnet connection and cutting off communication session to relay 30A.But, also can make based on the foundation of the communication session of SIP and cut off and carry out automatically.
Specifically; At first; Logining to relay 30A; Make the user of operating terminal 50 carry out following operation, that is, send with the telnet bind command (for example open order) of the mailing address (" SIP URI " or telephone number) of the upper layer of the relay (for example relay 30B) of setting object as long-range action as parameter to this relay 30A.For example, be under the situation of " 053XXXXXXX " at the telephone number of relay 30B, input " open 053XXXXXXX ".On the other hand, make the control part 310 of relay 30A carry out following processing.Promptly; The mailing address (in above-mentioned example, being " 053XXXXXXX ") of the upper layer that will provide as the parameter of telnet bind command (in above-mentioned example, being the open order) is as sending target; Step with based on SIP is set up communication session; Use is set up the IP address and the port numbers of this linking objective that obtains in the process at this, carries out to this linking objective and carries out the processing (the telnet process of commands is carried out as parameter in above-mentioned IP address and port numbers) that telnet connects.Here, providing under the situation of telephone number as the mailing address of upper layer, as long as " SIP: telephone number domain " is transformed to " SIP_URI " afterwards, the foundation of using this " SIP_URI " to communicate session gets final product.And, send under the situation of the indication of cutting off the telnet connection the user of operating terminal 50, make the control part 310 of relay 30A in this cut-out, carry out the processing of cutting off above-mentioned communication session.According to this mode, can obtain following effect, that is, and with the operational ton of foundation that is used to communicate session and cut-out correspondingly, user's operation burden is reduced.
(7) in the above-described embodiment; Explained the relay 30B that the network segment had under its command outside the network segments under the operating terminal 50 has been moved situation about setting; But also can use operating terminal 50; Carry out telnet with the relay 30A of this operating terminal 50 same network segments and be connected to being subordinated to, and the action of carrying out relay 30A set (that is, to long-range action set could indicate with configuration of routers in some or the two rewrite); In addition, can certainly operating terminal 50 and relay 30A be carried out action connected in series and that carry out relay 30A sets.
(8) in the above-described embodiment, will be used to make the control part 310 of relay 30 to carry out the program of the processing that characteristic of the present invention significantly is shown, be stored in advance in the storage part 350 of this relay 30.But; Also can in the storage medium that for example CD-ROM computer installations such as (Compact Disk-Read Only Memory) can read, write said procedure and distribute; In addition, also can distribute said procedure through downloading via electronic communication circuits such as the Internets.Its reason is; Through the procedure stores that will distribute as stated in common relay; Then; The control part of this relay is moved (so-called firmware upgrade) according to this program, thus can be to the relay identical functions of existing relay interpolation with above-mentioned execution mode.
(9) in the above-described embodiment,, to relay 30B, set with order through sending action, thereby the long-range action that realizes relay 30B is set in Telnet.At this moment, set with order, send the order of the action regulation parameter rewriting of indication relay 30B as moving.But in the present invention, the kind of order is not limited to indicate the order of action regulation parameter rewriting.Promptly; Also can be through sending the indication firmware update to relay 30B and obtain record (statistics, diagnosis, state show), carry out the order of particular script (for example Lua script) etc., thus the control of stipulating according to the order that is sent to relay 30B.
