技术领域technical field

本发明是有关于一种接口装置的管理装置、系统与方法，且特别是有关于一种采用雷电接口的接口装置的数据流量分析管理装置、系统与方法。The present invention relates to a management device, system and method of an interface device, and in particular to a data flow analysis management device, system and method of an interface device using a lightning interface.

背景技术Background technique

随着科技的进步，电脑的功能趋于多样化，各式各样的周边设备也不断推陈出新。为了能够方便使用者提升电脑效能或是扩充电脑功能，电脑的主机板上一般会配置加速图形端口(Accelerated Graphics Port，AGP)、周边元件内连接(Peripheral Component Interconnect，PCI)、快捷PCI(PCIExpress，PCI-E)等总线插槽，以供使用者插入显示卡、音效卡、网路卡等扩充卡。此外，电脑主机上也会配置火线(Firewire)、通用串行总线(Universal Serial Bus，USB)等扩充接口，以供使用者连接硬盘、打印机等外部装置。With the advancement of technology, the functions of computers tend to be diversified, and various peripheral devices are constantly being introduced. In order to facilitate users to improve computer performance or expand computer functions, the motherboard of the computer is generally equipped with accelerated graphics port (Accelerated Graphics Port, AGP), peripheral component interconnection (Peripheral Component Interconnect, PCI), express PCI (PCIExpress, PCI-E) and other bus slots for users to insert expansion cards such as graphics cards, sound cards, and network cards. In addition, expansion interfaces such as Firewire and Universal Serial Bus (USB) will also be configured on the host computer for users to connect external devices such as hard disks and printers.

最近，美国英特尔(Intel)公司推出了全新的雷电(Thunderbolt)接口，其系整合PCI-E和显示端口(DisplayPort)两项技术，而可在同一条缆线中同时传送数据及影像串流。图1是依照本发明一实施例所绘示的雷电接口的数据传输示意图。请参照图1，雷电传输技术是在同一条缆线12中提供两个通道122、124作为PCI-E和显示端口，以分别传输数据及影像串流。藉由配置在缆线12两端的雷电控制器14、16的控制，每个通道在两个方向上的传输都可达到每秒10千兆字节(GigaByte，GB)的传输量，使得电脑与周边设备之间可来回高速传输数据。雷电传输技术提供的频宽还可供多台高速装置以菊花链(Daisy-chain)的方式串接，而毋须使用集线器或交换器。Recently, Intel Corporation of the United States has launched a new Thunderbolt interface, which integrates two technologies of PCI-E and DisplayPort, so that data and video streams can be transmitted simultaneously in the same cable. FIG. 1 is a schematic diagram of data transmission of a Thunderbolt interface according to an embodiment of the present invention. Please refer to FIG. 1 , the Thunderbolt transmission technology provides twochannels 122 and 124 in thesame cable 12 as PCI-E and DisplayPort to transmit data and video streams respectively. Under the control of thelightning controllers 14 and 16 arranged at both ends of thecable 12, the transmission of each channel in both directions can reach a transmission volume of 10 gigabytes (GigaByte, GB) per second, so that the computer and Data can be transferred back and forth at high speed between peripheral devices. The bandwidth provided by Thunderbolt transmission technology can also allow multiple high-speed devices to be connected in daisy-chain without using hubs or switches.

举例来说，图2是习知雷电接口的菊花链串接架构。请参照图2，为了实现菊花链(Daisy-chain)的串接方式，作为主控端的主机22需要配置一个雷电接口端口222及一个支持双通道传输的雷电控制器224，其后续串接的雷电接口装置24、26、28则都需要配置两个以上的雷电接口端口242、244、262、264、282、284。其中，由于每个雷电接口均具有两个通道，因此这些雷电接口装置24、26、28内还需要配置一个支援支持4个通道的雷电控制器246、266、286，无形之间也增加了装置的生产成本。For example, FIG. 2 is a daisy-chain serial architecture of a conventional Thunderbolt interface. Please refer to Figure 2. In order to realize the daisy-chain connection method, thehost computer 22 as the main control terminal needs to be equipped with a Thunderboltinterface port 222 and a Thunderboltcontroller 224 that supports dual-channel transmission. Theinterface devices 24 , 26 , 28 all need to be equipped with more than twolightning interface ports 242 , 244 , 262 , 264 , 282 , 284 . Among them, since each Thunderbolt interface has two channels, these Thunderboltinterface devices 24, 26, 28 also need to be equipped with a Thunderboltcontroller 246, 266, 286 that supports 4 channels. production cost.

然而，目前雷电接口的两个通道仅个别用以传送数据及影像串流，不支持通道集成(channel aggregation)，从而使得传输效能受到限制。当使用者串接的雷电装置中不包含显示相关装置时，用以传输影像串流的通道将被闲置，连带使得高成本配置的雷电接口端口及雷电控制器只能提供一半的传输效能，形成资源浪费。此外，菊花链的串接架构也不具备容错(fault tolerance)功能，一旦有某个雷电装置发生异常或故障时，串接在后的雷电装置也随即失去连结而无法工作，严重时甚至会造成数据遗失的结果。However, currently, the two channels of the Thunderbolt interface are only used to transmit data and video streams individually, and do not support channel aggregation, which limits the transmission performance. When the Thunderbolt device connected in series by the user does not include a display-related device, the channel used to transmit the image stream will be idle, and the high-cost Thunderbolt interface port and Thunderbolt controller can only provide half of the transmission performance, resulting in Waste of resources. In addition, the serial structure of the daisy chain does not have the function of fault tolerance. Once a lightning device is abnormal or malfunctions, the lightning device connected in series will lose its connection and fail to work. In severe cases, it may even cause Data loss results.

图3A及图3B分别是依照本发明一实施例所绘示的接口装置方块图。请参照图3A，本实施例的接口装置32例如是采用雷电接口传输数据的图形处理装置(包含图形处理单元(GPU))、显示装置、音效装置、储存装置、网路连结装置、烧录装置或其他周边装置，其中包括第一接口端口321、控制器322、切换器323及第二接口端口324，这些元件的功能分述如下：3A and 3B are respectively block diagrams of an interface device according to an embodiment of the present invention. Please refer to FIG. 3A, the interface device 32 of this embodiment is, for example, a graphics processing device (including a graphics processing unit (GPU)) that uses a Thunderbolt interface to transmit data, a display device, an audio device, a storage device, a network connection device, and a burning device. Or other peripheral devices, including a first interface port 321, a controller 322, a switcher 323 and a second interface port 324, the functions of these components are described as follows:

第一接口端口321串接主机(未绘示)或另一接口装置(未绘示)的输出接口端口，而用以接收第一通道及第二通道的数据，并将此第一通道及第二通道的数据分流以在第一传输路径及第二传输路径上传输。其中，所述的第一通道及第二通道例如是雷电接口的两个数据传输通道。The first interface port 321 is serially connected to the output interface port of the host (not shown) or another interface device (not shown), and is used to receive the data of the first channel and the second channel, and transfer the first channel and the second channel The data of the two channels is split to be transmitted on the first transmission path and the second transmission path. Wherein, the first channel and the second channel are, for example, two data transmission channels of the Thunderbolt interface.

控制器322配置在第一传输路径上，用以处理经由第一传输路径传输的数据。其中，控制器322还包括连接至接口装置32的装置主体，使得该装置主体可经由第一传输路径接收并处理第一通道的数据。此装置主体即为上述图形处理装置、显示装置、音效装置、储存装置、网路连结装置、烧录装置等装置的硬件部分。The controller 322 is configured on the first transmission path for processing data transmitted through the first transmission path. Wherein, the controller 322 further includes a device body connected to the interface device 32, so that the device body can receive and process the data of the first channel through the first transmission path. The main body of the device is the hardware part of the above-mentioned graphics processing device, display device, audio device, storage device, network connection device, burning device and other devices.

切换器323分别连接第一传输路径与第二传输路径，而可根据所串接的主机发送的控制信号，切换第一传输路径与第二传输路径上传输的第一通道及第二通道的数据。其中，所述的控制信号例如是由控制器322由第一传输路径中撷取，从而输入切换器323的控制接点，藉以控制切换器323切换传输路径上传输的数据。The switcher 323 is connected to the first transmission path and the second transmission path respectively, and can switch the data of the first channel and the second channel transmitted on the first transmission path and the second transmission path according to the control signal sent by the host connected in series . Wherein, the control signal is, for example, captured by the controller 322 from the first transmission path, and then input to the control contact of the switch 323, so as to control the switch 323 to switch the data transmitted on the transmission path.

举例来说，图4是依照本发明一实施例所绘示的切换器的示意图。请参照图4，本实施例的切换器40例如是路由器市场上常见的高速切换器，其中包括一个控制接点E与四个数据接点A、B、C、D，接点A、B分别连接上述的第一传输路径与第二传输路径。切换器40的标准切换模式为当控制接点E接收到的控制信号为逻辑0时，即将接点A连接至接点C，并将接点B连接至接点D，此即代表原先在第一传输路径与第二传输路径上传输的第一通道及第二通道的数据维持不变；当控制接点E接收到的控制信号为逻辑1时，则将接点A连接至接点D，并将接点B连接至接点C，此即代表原先在第一传输路径与第二传输路径上传输的第一通道及第二通道的数据已经由切换器40的切换而对调。For example, FIG. 4 is a schematic diagram of a switch according to an embodiment of the present invention. Please refer to Fig. 4, the switch 40 of this embodiment is, for example, a common high-speed switch in the router market, which includes a control contact E and four data contacts A, B, C, D, and the contacts A and B are respectively connected to the above-mentioned The first transmission path and the second transmission path. The standard switching mode of the switch 40 is when the control signal received by the control point E is logic 0, that is, connecting the point A to the point C, and connecting the point B to the point D, which means that the first transmission path and the second The data of the first channel and the second channel transmitted on the two transmission paths remain unchanged; when the control signal received by the control node E is logic 1, then connect the node A to the node D, and connect the node B to the node C , which means that the data of the first channel and the second channel originally transmitted on the first transmission path and the second transmission path have been swapped by switching of the switch 40 .

第二接口端口324连接切换器323，用以输出经由切换器323切换的第一通道及第二通道的数据。第二接口端口324还用以串接另一个接口装置(未绘示)的第一接口端口，使得接口装置32可透过第二接口端口324将经由切换器323切换的第一通道及第二通道的数据输出至另一个接口装置。The second interface port 324 is connected to the switch 323 for outputting the data of the first channel and the second channel switched by the switch 323 . The second interface port 324 is also used to serially connect the first interface port of another interface device (not shown), so that the interface device 32 can switch the first channel and the second channel switched by the switch 323 through the second interface port 324. The data of the channel is output to another interface device.

上述的接口装置32中仅配置一个支持雷电接口的双通道数据传输的控制器322，以针对第一接口端口321所接收的其中一个通道的数据进行处理，并将另一个通道的数据越过(bypass)该接口装置32而提供给串接在后的另一个接口装置来处理。藉此，不仅可有效利用两个通道的传输效能，也可使系统具备容错功能。The above-mentioned interface device 32 is only configured with a controller 322 that supports dual-channel data transmission of the Thunderbolt interface, so as to process the data of one channel received by the first interface port 321 and bypass the data of the other channel. ) The interface device 32 is provided to another interface device connected in series for processing. In this way, not only the transmission performance of the two channels can be effectively utilized, but also the system can be provided with a fault-tolerant function.

与接口装置32不同的是，接口装置34还额外在第二传输接口上配置第二控制器343，而用以处理经由第二传输路径传输的数据。其中，第二控制器343还包括连接至接口装置34的装置主体，使得该装置主体可经由第二传输路径接收并处理第二通道的数据。此装置主体即为上述图形处理装置、显示装置、音效装置、储存装置、网路连结装置、烧录装置等装置的硬件部分。Different from the interface device 32, theinterface device 34 is additionally configured with asecond controller 343 on the second transmission interface for processing data transmitted via the second transmission path.

FIG. 7 is a flowchart of a method for analyzing and managing data traffic of an interface device according to an embodiment of the present invention. Please refer to FIG. 6 and FIG. 7 at the same time. The trafficanalysis management device 60 of this embodiment includes aninterface port 61 and acontroller 62 . Wherein, theinterface port 61 is used for serially connecting the interface device (not shown), and thecontroller 62 is used for providing the data of the first channel and the second channel, including adetection module 621, ananalysis module 622 and amanagement module 623 . The detailed steps of the traffic analysis and management method of this embodiment will be described below in combination with various elements of the traffic analysis andmanagement device 60 in FIG. 6 .

首先，由检测模组621检测串接在流量分析管理装置60之后的接口装置，并取得各个接口装置的装置信息(步骤S702)。所述的装置信息包括各个接口装置的频宽需求、数据备份需求或处理数据的优先顺序等，在此不设限。Firstly, thedetection module 621 detects the interface devices serially connected to the flowanalysis management device 60, and obtains device information of each interface device (step S702).

然后，管理模组623会根据分析模组622所决定的传输路径，发送控制信号至各个接口装置，以控制其中的切换器切换第一通道及第二通道的数据的传输路径(步骤S706)。Then, themanagement module 623 sends a control signal to each interface device according to the transmission path determined by theanalysis module 622, so as to control the switch therein to switch the data transmission path of the first channel and the second channel (step S706).

举例来说，图8是依照本发明一实施例所绘示的接口装置的数据流量分析管理系统的范例。请参照图8，本实施例的数据流量分析管理系统80包括采用雷电接口的菊花链方式串接的数据流量分析管理装置81以及接口装置82、83、84、85。其中，数据流量分析管理装置81由控制器811透过雷电接口提供第一通道及第二通道的数据传输功能。For example, FIG. 8 is an example of a data flow analysis and management system of an interface device according to an embodiment of the present invention. Referring to FIG. 8 , the data trafficanalysis management system 80 of this embodiment includes a data trafficanalysis management device 81 andinterface devices 82 , 83 , 84 , and 85 connected in daisy-chain manner using Thunderbolt interfaces. Wherein, the data flow analysis andmanagement device 81 is provided with the data transmission function of the first channel and the second channel by thecontroller 811 through the Thunderbolt interface.

接口装置82将第一通道及第二通道的数据分流在第一传输路径及第二传输路径上传输，控制器821则配置在第一传输路径上，使得控制器821所连接的图形处理单元(Graphic Processing Unit，GPU)823可对第一通道的数据进行处理。切换器822则可根据控制器811输出的控制信号切换在第一传输路径及第二传输路径上传输的数据。Theinterface device 82 divides the data of the first channel and the second channel for transmission on the first transmission path and the second transmission path, and thecontroller 821 is configured on the first transmission path, so that the graphics processing unit (GPU) connected to the controller 821 ( Graphic Processing Unit (GPU) 823 can process the data of the first channel.

接口装置83将第一通道及第二通道的数据分流在第一及第二传输路径上传输，控制器831、832分别配置在第一及第二传输路径上，使得控制器831所连接的硬盘834中的数据可提供第一通道上的装置进行存取，而控制器832所连接的硬盘835中的数据则可提供第二通道上的装置进行存取。切换器833根据控制器811输出的控制信号切换在第一传输路径及第二传输路径上传输的数据。Theinterface device 83 divides the data of the first channel and the second channel for transmission on the first and second transmission paths, and thecontrollers 831 and 832 are respectively arranged on the first and second transmission paths, so that the hard disk connected to thecontroller 831 The data in 834 can be accessed by devices on the first channel, and the data in thehard disk 835 connected to thecontroller 832 can be accessed by devices on the second channel. Theswitcher 833 switches the data transmitted on the first transmission path and the second transmission path according to the control signal output by thecontroller 811 .

硬盘834、835可分别作为磁盘阵列(RAID)中的两个磁盘，例如是作为RAID 0及RAID 1，而可用以备份数据流量分析管理装置81中的重要数据。其中，数据流量分析管理装置81透过第一通道及第二通道分别传输备份数据至硬盘834、835，而可将备份数据分别储存在硬盘834、835。藉此，即便硬盘834、835中的任何一个装置发生异常或故障，另一个装置仍保有备份数据，从而达到数据容错功能。Thehard disks 834 and 835 can be respectively used as two disks in a disk array (RAID), such as RAID 0 and RAID 1, and can be used to back up important data in the data flowanalysis management device 81. Wherein, the data trafficanalysis management device 81 transmits the backup data to thehard disks 834 and 835 respectively through the first channel and the second channel, and can store the backup data in thehard disks 834 and 835 respectively. In this way, even if any one of thehard disks 834, 835 is abnormal or fails, the other device still retains the backup data, thereby achieving the data fault tolerance function.

接口装置84将第一通道及第二通道的数据分流在第一传输路径及第二传输路径上传输，控制器841则配置在第一传输路径上，使得控制器841所连接的光盘驱动器843可提供第一通道上的装置进行光碟的读取及写入操作。切换器842则可根据控制器811输出的控制信号切换在第一传输路径及第二传输路径上传输的数据。Theinterface device 84 divides the data of the first channel and the second channel for transmission on the first transmission path and the second transmission path, and thecontroller 841 is arranged on the first transmission path, so that theoptical disc drive 843 connected to thecontroller 841 can The device on the first channel is provided for reading and writing operations of the optical disc.

接口装置85将第一通道及第二通道的数据分流在第一及第二传输路径上传输，控制器851、852分别配置在第一及第二传输路径上，使得控制器851所连接的网路卡854可提供第一通道上的装置连接区域网路或网际网路以存取网路数据，而控制器852所连接的音效卡855则对第二通道上的数据进行音效处理。切换器853根据控制器811输出的控制信号切换在第一传输路径及第二传输路径上传输的数据。Theinterface device 85 divides the data of the first channel and the second channel for transmission on the first and second transmission paths, and thecontrollers 851 and 852 are respectively arranged on the first and second transmission paths, so that the network connected to thecontroller 851 Theroad card 854 can provide devices on the first channel to connect to the LAN or the Internet to access network data, and the sound card 855 connected to thecontroller 852 performs sound processing on the data on the second channel. Theswitcher 853 switches the data transmitted on the first transmission path and the second transmission path according to the control signal output by thecontroller 811 .

需说明的是，数据流量分析管理装置81由控制器811例如是在有接口装置82、83、84、85串接时，即透过上述的第一通道及第二通道取得各个接口装置82、83、84、85的装置信息，并据以决定第一通道及第二通道的数据在各个接口装置82、83、84、85中的传输路径。其中，控制器811例如会判断GPU 823及网路卡854的数据流量较大，需要占用较大的传输频宽，因此会采用负载平衡策略，将这两种装置的传输路径分开。而又由于GPU 823对于传输频宽的需求最大，因此控制器811例如会针对GPU 823采用流量最佳化策略，而控制切换器833切换GPU 823所在的传输路径，以避开光盘驱动器843。如图8中的粗箭头所示，控制器811针对GPU 823所规划的传输路径上只包括GPU 823、硬盘834及音效卡855，藉此可让GPU 823获得最大的传输频宽，从而达到传输效能的最佳化。It should be noted that, the data flow analysis andmanagement device 81 is obtained by thecontroller 811, for example, when there areinterface devices 82, 83, 84, and 85 connected in series, that is, through the above-mentioned first channel and second channel, eachinterface device 82, 83, 84, 85 device information, and based on this, determine the transmission path of the data of the first channel and the second channel in eachinterface device 82, 83, 84, 85. Wherein, thecontroller 811, for example, judges that the data traffic of theGPU 823 and thenetwork card 854 is relatively large and needs to occupy a relatively large transmission bandwidth, so a load balancing strategy is adopted to separate the transmission paths of the two devices. And because theGPU 823 has the greatest demand for transmission bandwidth, thecontroller 811, for example, adopts a traffic optimization strategy for theGPU 823, and controls theswitcher 833 to switch the transmission path where theGPU 823 is located, so as to avoid theoptical disk drive 843. As shown by the thick arrow in Figure 8, the transmission path planned by thecontroller 811 for theGPU 823 only includes theGPU 823, thehard disk 834 and the sound card 855, so that theGPU 823 can obtain the maximum transmission bandwidth, thereby achieving transmission Optimization of performance.

综上所述，本发明的接口装置的数据流量分析管理装置、系统与方法藉由分析主机所串接的接口装置的特性，据以分配并切换雷电接口两个通道的数据传输路径，而可达到数据流量的负载平衡、数据容错，以及流量最佳化等功效。To sum up, the data flow analysis and management device, system and method of the interface device of the present invention can allocate and switch the data transmission paths of the two channels of the Thunderbolt interface by analyzing the characteristics of the interface devices connected in series to the host computer.
