Embodiment can also can be applied to multiple network equipment based on the method and apparatus of the physical topology of real-time application monitor network.For example, as described below, exemplary embodiment can be applicable to come based on the terminal block connectedness of dynamic monitoring the physical topology of monitor network.
Can network be described by logical topology and physical topology.The logical topology of network comprises the information of the logical connectivity that relates to the equipment that is connected to this network.For example, the logical topology that is used for data or communication network can represent to be connected to the existence and the identity of network of network equipment (for example router, switch, intelligent HUB etc.), the existence and the connectedness of end user device (for example server, network data base, printer, teller work station etc.), the logical connectivity of equipment room (for example using the logic port on each of each equipment that is used to communicate by letter), and the logical place of equipment (for example Internet Protocol of static state or dynamic assignment (IP) number etc.).These information can be managed by network management system (nms), and its reception and storage package are contained in the information in Simple Network Management Protocol (SNMP) message, and this snmp message produces and send to NMS by the independent network equipment and/or end user device.
The physical topology of network can comprise the physical location that relates to equipment (as building, equipment storeroom etc.), and LA Management Room and the network equipment and terminal use between the information of physical connection (for example device identifier/physical port etc.).Physical connection information between these network equipments and terminal use preferably includes the physical connection/cable trace between each LA Management Room and the network equipment and terminal use.
Be in charge of the network manager of big information technology (IT) structure and thirst for visiting accurate and comprehensive logical network topology information for a long time, the combination of this logical network topology information and accurate and comprehensive physical network topology information, thus the view of single whole of their IT environment formed.
Can be based on the physical measurement of physical structure, manual collection physical topology information.The task of carrying out physical measurement can often be become complicated, this be by can not physical access to the absolute magnitude of the network equipment and/or end user device, interconnective cable, in the cable panel, use passive termination/tie point (for example terminal block, distribution panel etc.) so that the connectedness of LA Management Room to be provided, and provide the connectedness between the network equipment and end user device to cause.The cable amount adds inconsistent mark agreement (perhaps at all not having mark), makes that the task of safeguarding accurate physical topology information is very difficult and expensive.Therefore, the accurate physical topology information of visit network enabled error detection/recovery processing and/or long or short-term maintenance plan is difficult.Following discussion uses terminal block as an example with easy to understand.
Although some terminal block can support to determine the basic scheme of the patch panel port that connects by patch cord, these systems uncertain physical equipment and/or the physical location information relevant with each patch panel port.Therefore these systems do not provide the physical network topology information with each patch cord join dependency, or network route information.
Because more than, the terminal block of patch panel port level connectedness can be monitored and report to expectation, but this connectedness is based on the distributed frame of modularization upgrading.When having set up the patch cord connection, this scheme should preferably can be determined physical equipment and/or the physical location information relevant with each patch panel port, and therefore dynamic network topological information is provided in real time, or with the network route information of each patch cord join dependency.Further, if do not eliminate, this scheme should reduce polling delay and poll related overhead processing preferably by support the real-time monitoring of port connectivity at port level.In addition, this scheme should provide the real-time report of the terminal block connectedness of the cable complexity that having of improvement reduce, and has improved reliability and has reduced maintenance cost.

As described in more detail below, each the I-panel terminal port controller of managing in each port can be configured to except that I-panel identifier and port identifiers, comprise the physical topology information that relates to physical equipment (for example switch/port) and/or physical location (office/wall jack) information relevant with each terminal block, this terminal block is connected to the back of the body end of each patch panel port by cable or rigid line.Further, as described below, physical topology information can pass to its each terminal block controller by each port controller, and can be delivered to NMS from the panel controller module of connection Network Based.In this mode, when terminal block was connected to form, the I-panel can be in real time for NMS provides information, and this information comprises physical network topology information, and/or with the network route information of each patch cord join dependency.Further, when changing generation,, guaranteed the physical network topology information or the network route information of NMS real time access high precision by the variation in dynamic monitoring and the dynamic report patch panel port connectedness.
Each I-panel terminal port repeated broadcast outbound message on outband channel.In addition, each I-panel terminal port can be monitored the reception of the outbound message that another I-panel terminal port from the outband channel sends.When the patch cord of communication channel was connected two I-panel terminal ports outside tenaculum, port was just understood the outer message of receiving belt.Yet, based on two connections (patch cord that for example has the 9th line) with I-panel terminal port of the outer communication channel patch cord of tenaculum, each I-panel terminal port can receive outbound message, and this outbound message is to be broadcasted by the I-panel terminal port that uses it to connect.The I-panel terminal port controller relevant with each port then can be in real time produces updating message to their each I-panel terminal block controller.After receiving updating message from port controller, each I-panel terminal block controller can produce and connect to long-range NMS by network and send updating message, and this NMS is configured to organize and present received physical topology information in the mode that can be used for the terminal use.Received physical topology information can any desired form present to the technical staff, as passing through display, printout or LED.
Fig. 2 is the structural level diagrammatic sketch of an exemplary modular i-panel configuration.As shown in Figure 2, I-panel 400 comprises a panel controller module 402, itself and a plurality of port controller modules 404 (a)-(n) communicate by letter.Further, this I-panel controller module 402 can be supported to communicate by letter with another I-panel and/or network management system with 420 (b) by daisy chain network connection port 420 (a).In addition, I-panel 400 can receive electric energy from power supply or another I-panel, and can pass through daisy chain energy connectivity port 418 (a) and 418 (b) and energy management circuit 424 and give another I-panel with energy delivery.As described in more detail in the following with reference to FIG 4, each of port controller module 404 (a)-(n) can be by monitoring the port level connectedness that the out-of-band communication channel relevant with port comes policing port.This out-of-band communication channel can be supported by the 9th rump electron contact relevant with the institute policing port.For example, as shown in Figure 2, by each monitor respectively one with based on relevant the 9th core band exoelectron contact 406 (a)-(n) of each RJ-45 of socket 408 (a)-(n), port controller module 404 (a)-(n) respectively policing port 1 to N.
Fig. 3 is the structure chart of an exemplary I-panel panel controller module 502.As shown in Figure 3, panel controller module 502 can comprise a panel controller/processor module 510, and it is communicated by letter with data memory module 508, Network Interface Module 506 and a plurality of port controller module 504 (a)-(n).

Different panel controller module 502 configurations can comprise a panel controller/processor module 510, and it has the ability from general function to high complicated monitoring and controlled function.So, need the hardware/software module to realize panel controller module 502, the scope of this hardware/software module can be from having the relative simple module with disposal ability of limited storage to the module with high storage and disposal ability relative complex.
Fig. 4 is the structure chart of described exemplary port controller module.As shown in Figure 4, port controller module 604 can comprise a port controller/processor module 606, and it is communicated by letter with data memory module 612 with outband channel connectivity module 608.Port controller/processor module 606 can further directly or by outband channel connectivity module 608 be communicated by letter with outband channel physical interface 610, and can communicate by letter with optional port arrangement device interface 618 (as shown in phantom in Figure 4).As shown in Figure 4, port controller/processor module 606 needn't be monitored, or influence is through the data of port controller module 604 by any way, and these data are by terminal block front ports physical interface 614 and terminal block back side ports physical interface 616 process port controller modules 604.But, (for example wherein port controller module 604 is configured to the embodiment of transponder) in one embodiment, when signal process port controller module 604, can some mode (as amplifying) be handled by the data-signal of process port controller module 604.
As above described in conjunction with Fig. 3, port controller/processor module 606 can with I-panel panel controller module communication, thereby to this panel controller module transmit port updating message, and receive the renewal of configuration/Control Parameter from the panel controller module.After receiving updating message from the panel controller module, port controller/processor module 606 renewable state informations that are stored in the data memory module 612.Port controller/processor module 606 can use from I-panel panel controller module and receive and be stored in parameter the data memory module 612, thereby, also control the incident that reports to the panel controller module by updating message thereby control by the incident of port controller module 604 monitoring in conjunction with the operation that the operation of being carried out by the port controller module comes control port controller module 604.
In an embodiment of port controller module, port controller/processor module 606 can reappear local cabling panel sign symbols, local port identifier, local port connection status and that stored and physical network topology information (the I-panel/port information that for example relates to current or local I-panel terminal port) current or that the local port controller module is relevant from data memory module 612.Port controller/processor module 606 can provide the information of reproduction to outband channel connectivity module 608.Outband channel connectivity module 608 can produce an outbound port message then, and this message comprises as above local cabling panel sign symbol, local port identifier and physical network topology information in conjunction with the described reproduction of Figure 1A.Outband channel connectivity module 608 can proceed on outband channel and send this outbound port message by transmitter, and this transmitter is by 610 operations of outband channel physical interface.Further, outband channel connectivity module 608 can receive an inbound messages from remote port by the receiver by 610 operations of outband channel physical interface, and this message comprises as the described remote cabling panel sign symbol of above 1A in conjunction with the accompanying drawings, remote port identifier information and physical network topology information.

Term " remote port " is relative term with " local port ".For example, from the angle of I-panel terminal port controller, any port " local port " that term " remote port " can be used for representing to support except that I-panel terminal port controller.Provided the I-panel and can support a plurality of ports, " remote port " can be one on identical or local I-panel as the port of " local port ", perhaps " remote port " can be a port on another or remote I-panel.Except each had relative position about another, remote port and local port performance were identical.For example, each port based on the angle of that port, sends the outer outbound port message of a band, and this message comprises local cabling panel sign symbol and local port identifier.Further, each port, based on the angle of that port, receiving remote terminal block identifier and remote port identifier in the message that receives.
In above typical embodiment, local I-panel is an example of " local device ", and remote I-panel is an example of " remote-control device ".Yet this local device can be any equipment unit that is connected by network with remote-control device, and this equipment network enabled cable connects monitoring and/or physical network topology monitoring.For example, the local device with local port can be that terminal block, switch, router, hub, terminal use's device, printer or any other can the network enabled cable connect the network connection device of monitoring and/or physical network topology monitoring.Further, the remote-control device with remote port can be that terminal block, switch, router, hub, terminal use's device, printer or any other can the network enabled cable connect the network connection device of monitoring and/or physical network topology monitoring.In addition, the combination of any local device and remote-control device can be communicated by letter to support above-mentioned network cable to be connected monitoring processing and/or physical network topology monitoring processing.
Refer again to Fig. 3, the port controller module can be configured to comprise physical equipment (for example switch/port) and/or physical location (office/wall socket) information in I-panel terminal port identifier information, these information are relevant with each the terminal block cable that terminates in port controller module 604 by terminal block back side physical interface 616.As mentioned above, after having set up new patch cord and connecting, this I-panel/port identifiers information and physical network topology information can exchange based on the patch cord outband channel 604 of I-panel terminal port controller modules.For example, physical network topology information can be included in the initial broadcast message together with I-panel/port identifiers information, and/or exchanges between port after port has detected mutually.Further, as mentioned above, can link information be passed to its each panel controller module by each port controller module, and can connection Network Based be delivered to NMS from the panel controller module.In this mode, when terminal block is connected to form, the I-panel can offer in real time the NMS physical network topology information or with the network route information of each patch cord join dependency.Further, by the variation in dynamic monitoring and the dynamic report patch panel port connectedness, when changing generation, NMS real time access high precision physical network topology information or network route information have been guaranteed.
Determined to have taken place in the port level connectedness change based on the band external information that monitors after, outband channel connectivity module 608 can be notified port controller/processor module 606.As above described in conjunction with Fig. 3, state information and the up-to-date physical network topology information that receives that port controller/processor module 606 can storage update be crossed in data memory module 612, and send updating message to the panel controller module.
In 604 configurations of an example port controller module, port controller/processor module 606 can support that by inking device receiving port configuration data this inking device is connected to port controller module 604 by terminal block front ports physical interface 614 and/or by optional port arrangement device interface 618.For example, inking device such as PDA(Personal Digital Assistant) or kneetop computer can be connected to port controller module 604 by terminal block front physical interface 614 or by optional port arrangement device interface 618, thereby load physical network topology informations (for example building name, equipment storeroom identifier, device identification/physical port identifier etc.) by terminal block back side physical interface 616, this physical network topology information and physical location and/or to be connected to the equipment that the cable of port controller module 604 supports relevant.
As mentioned above, different port controller block configuration can comprise a port controller/processor module, and it has the ability from general function to high complicated monitoring and controlled function, and the data through the I-panel terminal port are not monitored or controlled to this general function.So, need the hardware/software module to realize port controller module 604, it can be from relatively simply module be to the module of relative complex, and simple relatively module has less storage and disposal ability, and the module of relative complex has bigger storage and disposal ability.
