Description
本發明係關於一種網路管理裝置,特別係一種可以進行無線傳輸之具有無線傳輸之網路管理裝置。 The invention relates to a network management device, in particular to a network management device with wireless transmission that can perform wireless transmission.
隨著低成本、低功耗之中央處理器(Central Processing Unit,CPU)或微控制器(Microcontroller Unit,MCU)等,提供更多的連結介面,例如藍牙(Bluetooth)或紫蜂(Zigbee)等無線協議,提供了更多的連結可能性。然而,目前一般的乙太網路供電方式,多半係藉由裝置中的CPU,再經由瀏覽器透過有線或無線的方式進行實體設備連結及管理。成本角度而言,可以達到完整的遠、近端管理,但成本略高。 With low-cost, low-power Central Processing Unit (CPU) or Microcontroller Unit (MCU), etc., more connection interfaces are provided, such as Bluetooth or Zigbee. Wireless protocols provide more connectivity possibilities. However, the current general Ethernet power supply method is mostly through the CPU in the device, and then through the browser to connect and manage the physical device through wired or wireless means. From a cost perspective, complete remote and near-end management can be achieved, but the cost is slightly higher.
並且,請參照第一圖所示,習知的乙太網路交換裝置10,內部具有一中央處理器12用於控制交換器10中的各單元,中央處理器12係電性連接至一乙太網路交換處理器14,一般來說,中央處理器12與交換處理器14具有二線路連接,第一線路P1係可為通用非同步收發傳輸器(Universal Asynchronous Receiver/Transmitter,UART),係一種RS-232串列埠或I2C(Inter-Integrated Circuit)介面,中央處理器12可藉由第一線路P1連接交換處理器14及一供電處理器16,以進行管理控制;第二線路P2係為乙太網路傳輸介面,中央處理器12可以將交換處理器14所傳輸的資訊處理,再藉由網路介面18,以傳輸至外部使用者的電腦20進行管理控制。 Moreover, as shown in the first figure, the conventional Ethernet switching device 10 has a central processing unit 12 for controlling each unit in the switching unit 10, and the central processing unit 12 is electrically connected to a second switching unit. The Ethernet switching processor 14, generally speaking, the central processing unit 12 and the switching processor 14 have a two-line connection. The first line P1 can be a Universal Asynchronous Receiver / Transmitter (UART). An RS-232 serial port or I 2 C (Inter-Integrated Circuit) interface. The central processing unit 12 can be connected to the switching processor 14 and a power supply processor 16 through a first line P1 for management control; a second line P2 is an Ethernet transmission interface. The central processing unit 12 can process the information transmitted by the switching processor 14 and then use the network interface 18 to transmit to the external user's computer 20 for management control.
因此,中央處理器12需要具備有網路介面122及管理介面124,以透過管理介面124電性連接第一線路P1及透過網路介面122電性連接第二線路P2,利用網路介面122及管理介面124管理交換處理器14及供電處理器16。然而,這樣會具有以下缺點,假設交換處理器14具有二十四個埠,在實際設計上只能是二十三個埠的設計,因為要預留一個埠給中央處理器12,並且當網路發生廣播封包時,因為交換處理器14被廣播封包堵塞時,中央處理器12會容易無法收到管理封包,或是瞬間湧入過多的廣播封包至中央處理器12,導致管理效能變差。 Therefore, the central processing unit 12 needs to have a network interface 122 and a management interface 124 to electrically connect the first line P1 through the management interface 124 and the second line P2 through the network interface 122, and use the network interface 122 and The management interface 124 manages the switching processor 14 and the power supply processor 16. However, this will have the following disadvantages. Assuming that the switch processor 14 has twenty-four ports, it can only be designed with twenty-three ports in actual design, because one port is reserved for the central processing unit 12, and the network When a broadcast packet occurs on the channel, when the switching processor 14 is blocked by the broadcast packet, the central processing unit 12 may be unable to receive the management packet, or an excessive number of broadcast packets may be flooded to the central processing unit 12 instantly, resulting in poor management performance.
因此,本發明為了解決習知乙太網路交換裝置資料傳輸堵塞時,管理效能下降的缺失,提出一種具有無線傳輸之網路管理裝置,避免資料傳輸堵塞及提高管理效能。 Therefore, the present invention proposes a network management device with wireless transmission in order to solve the lack of management performance degradation when the data transmission congestion of the conventional Ethernet switching device is blocked, so as to avoid data transmission congestion and improve management efficiency.

Next, it is electrically connected to the central processor 34 to the antenna, while the management element 344 is electrically connected to the network processor 32, and the network element 346 is a signal to connect to the network processor 32. The network packet is used to communicate with the network. The processor 32 makes a network connection and connects to the external device 38 through the network interface 36.
說明完本發明的連接方式及架構後,接著詳細說明本發明的作動方式,並請同時參照本發明第三圖所示,在本實施例中,先以一個網路處理器32為例說明,網路處理器32藉由網路介面36的連接可以接至外部裝置38,以接收外部裝置38所傳輸的第一資料,本實施例先以三個網路介面36為例說明,及第一資料係可為網路封包,不限制為管理者經由網路封包所發出之設備管理封包,在此網路封包係為IEEE802.3之乙太網路封包,本發明不限制一個網路處理器32可以連接多少網路介面36,端看使用者設計。當網路處理器32接收第一資料後,可以再將第一資料經由中央處理器34的管理元件344傳輸至中央處理器34中,接著中央處理器34可以將第一資料轉換成第二資料,在本實施例中第二資料係可為管理訊號,主要是中央處理器34針對網路處理器32所產生的管理訊號,在此管理訊號係為I2C、RS232等數位電子訊號匯流排型式之介面,本發明不限制中央處理器34該如何處理及轉換資料的方式,另外,當進入中央處理器34的第一資料太多時,中央處理器34也能將第一資料先暫存於儲存器40中,或是將處理完的第二資料先暫存在儲存器40中,儲存器40所儲存的第一資料或第二資料即可供中央處理器34存取使用。 After explaining the connection mode and architecture of the present invention, then the operation mode of the present invention will be described in detail, and please also refer to the third figure of the present invention. In this embodiment, a network processor 32 is taken as an example. The network processor 32 can be connected to the external device 38 through the connection of the network interface 36 to receive the first data transmitted by the external device 38. This embodiment first uses three network interfaces 36 as an example to describe, and the first The data may be a network packet, and is not limited to a device management packet sent by a manager via the network packet. Here, the network packet is an IEEE802.3 Ethernet packet. The present invention does not limit a network processor. 32 how many network interfaces 36 can be connected, depending on user design. After the network processor 32 receives the first data, the first data may be transmitted to the central processor 34 through the management element 344 of the central processor 34, and then the central processor 34 may convert the first data into the second data. In this embodiment, the second data may be a management signal, which is mainly a management signal generated by the central processor 34 for the network processor 32. Here, the management signal is a digital electronic signal bus such as I 2 C, RS232, etc. In the interface of the type, the present invention does not limit how the central processing unit 34 processes and converts data. In addition, when there is too much first data entering the central processing unit 34, the central processing unit 34 can also temporarily store the first data first. In the storage 40, or the processed second data is temporarily stored in the storage 40, and the first data or the second data stored in the storage 40 can be accessed and used by the central processing unit 34.
承接上段,中央處理器34可以選擇性將第二資料藉由無線元件 342,透過無線傳輸的方式直接傳輸到外部裝置38中。或是,中央處理器34可以藉由管理元件344將第二資料傳輸至網路處理器32,再藉由網路處理器32傳輸經網路介面36以傳輸至外部裝置38。但是,又因為中央處理器34會藉由網路元件346與網路處理器32進行網路封包的傳輸,一旦網路處理器32若堵塞時,中央處理器34就可以不用經由網路處理器32傳輸第二資料,直接利用自身的無線元件342進行傳輸。 Following the upper stage, the central processing unit 34 may selectively pass the second data to the wireless component. 342. Directly transmitted to the external device 38 through wireless transmission. Alternatively, the central processing unit 34 may transmit the second data to the network processor 32 through the management element 344, and then transmit the second data to the external device 38 through the network interface 36 through the network processor 32. However, because the central processing unit 34 transmits network packets to and from the network processing unit 32 through the network element 346, if the network processing unit 32 is blocked, the central processing unit 34 may not pass through the network processing unit. 32 transmits the second data, and directly uses its own wireless element 342 for transmission.
當使用者決定利用中央處理器直接藉由無線網路與外部裝置進行傳輸時,其實可以減少一個網路介面的使用,因為此時的中央處理器可以不用經由網路元件將資料傳輸到網路處理器,使得網路處理器就不用多一個網路介面或連接埠的使用。 When the user decides to use the central processing unit to transmit directly to the external device through the wireless network, it can actually reduce the use of a network interface because the central processing unit can transmit data to the network without using network components Processor, so that the network processor does not need to use an additional network interface or port.
另外,請參照本發明第四圖所示,因為中央處理器具有無線傳輸的能力,因此可以使多個具有無線傳輸之網路管理裝置進行溝通,例如網路管理裝置30、網路管理裝置30’、網路管理裝置30”,其中的網路管理裝置30為主要管理裝置,而網路管理裝置30’及網路管理裝置30”為從屬管理裝置,附屬於網路管理裝置30之下,此時使用者可以操作外部裝置38,例如智慧型手機或電腦,利用軟體或是APP的方式利用網路管理裝置30直接管理網路管理裝置30’、網路管理裝置30”。同時,也可以解決一般若要進行主、從管理裝置,要透過實體線路先連接至乙太網路交換器的需求。 In addition, please refer to the fourth figure of the present invention. Because the central processing unit has the capability of wireless transmission, multiple network management devices with wireless transmission can be communicated, such as the network management device 30 and the network management device 30. ", Network management device 30", of which the network management device 30 is the main management device, and the network management device 30 'and the network management device 30 "are slave management devices attached to the network management device 30, At this time, the user can operate the external device 38, such as a smart phone or a computer, and use the network management device 30 to directly manage the network management device 30 'and the network management device 30 "using software or an APP. At the same time, it can also To solve the general need to perform master and slave management devices, you must first connect to the Ethernet switch through a physical line.
再者,因為本發明網路管理裝置具有無線傳輸的能力,當安裝在昏暗或是腹地龐大的機房中,使用者可以利用手上的手提式裝置,例如筆記型電腦或是智慧型手機,透過無線控制的方式,尋找到欲尋找的網路管理裝置,例如可以在硬體設備上裝設有LED指示燈,透過軟體的控制可以使指示燈發光,以利使用者搜尋,一旦發現網路管理裝置有異常,此一方 式可以更快速找到有問題的網路管理裝置,另外也可以在網路管理裝置外接有一如SMA型式之接頭,以外接天線的方是增強無線訊號之傳輸。並且,無線傳輸之無線協議,例如藍牙、Zigbee、Z-wave或Wi-Fi等無線介面具有低功耗的特性,若將本發明的網路管理裝置結合不斷電系統(UPS),即便發生停電或斷電的情況,也能長時間給予中央處理器供電,並進行定位以供搜尋。 Furthermore, because the network management device of the present invention has the capability of wireless transmission, when installed in a dim or huge hinterland computer room, the user can use a hand-held device, such as a notebook computer or a smart phone, through In the wireless control mode, you can find the network management device you want to find.

Once the network management is found, Device is abnormal, this side You can find the problematic network management device more quickly. In addition, you can also connect a SMA type connector to the network management device. The external antenna is used to enhance the transmission of wireless signals. In addition, wireless protocols such as Bluetooth, Zigbee, Z-wave, or Wi-Fi have low power consumption characteristics. If the network management device of the present invention is combined with a UPS, even if In the event of a power outage or outage, it can also power the central processor for a long time and locate it for searching.
正也因為本發明之具有無線傳輸之網路管理裝置中的中央處理器,取代了習知的串列介面,及解決了用於連接乙太網路額外的乙太網路連接埠,因此本發明不會被乙太網路的現況影響到設備的管理。本發明在待機模式中,中央處理器可以週期性發出設備廣播訊息以偵測附近是否有同屬性的設備,以及是否有使用者需要進行管理設備的需求,當周圍有其它屬性設備也發出同樣的廣播訊息時,則可以進入上述如第四圖所示的群組模式,使得本發明具有無線傳輸之網路管理裝置除了上述的優點外,還可以大大提升設備的管理功效。 It is also because the central processing unit in the network management device with wireless transmission of the present invention replaces the conventional serial interface and solves the extra Ethernet port for connecting to the Ethernet. The invention will not affect the management of the device by the current situation of Ethernet. In the standby mode of the present invention, the central processor can periodically send device broadcast messages to detect whether there are devices with the same attributes nearby, and whether there is a need for users to manage the devices. When there are other attributes devices in the vicinity, the same When broadcasting a message, it can enter the group mode shown in the fourth figure above, so that the network management device with wireless transmission of the present invention can greatly improve the management efficiency of the device in addition to the advantages described above.
