圖2是圖1所示的系統的運作示意圖。請同時參照圖1及圖2。FIG2 is a schematic diagram of the operation of the system shown in FIG1. Please refer to FIG1 and FIG2 at the same time.

在步驟S210中，光網路設備30可將終端設備10的網路封包轉換為光訊號。在一實施例中，家用閘道模組31可對網路封包執行網路管理操作。網路管理操作例如是管理網路封包的標籤與IP。然後，固定接取網路光纖網路模組32可對網路封包執行VLAN處理操作。VLAN處理操作例如是VLAN轉換與QOS相關的功能。In step S210, the optical network device 30 can convert the network packet of the terminal device 10 into an optical signal. In one embodiment, the home gateway module 31 can perform network management operations on the network packet. The network management operation is, for example, managing the label and IP of the network packet. Then, the fixed access network optical fiber network module 32 can perform VLAN processing operations on the network packet. The VLAN processing operation is, for example, VLAN conversion and QOS related functions.

然後，光網路設備30可傳送光訊號至固定接取網路光纖分配網路50。接著，固定接取網路光纖分配網路50可傳送光訊號至固定接取網路光纖線路局端60。Then, the optical network equipment 30 can transmit the optical signal to the fixed access network optical fiber distribution network 50. Then, the fixed access network optical fiber distribution network 50 can transmit the optical signal to the fixed access network optical fiber line central office 60.

在步驟S220中，固定接取網路光纖線路局端60可將光訊號轉換為網路封包。詳細而言，被動式固定接取網路光纖網路模組61可將光訊號轉換為網路封包。In step S220, the fixed access network optical fiber line central office 60 can convert the optical signal into a network packet. Specifically, the passive fixed access network optical fiber network module 61 can convert the optical signal into a network packet.

接著，固定接取網路光纖線路局端60可根據網路封包的特徵（例如標籤與IP）來判斷，要將網路封包傳送至固定接取網路光纖線路局端專網邊緣主機90、專網光網路設備端專網邊緣主機20或者網際網路服務70。以下將繼續說明。Then, the fixed access network optical fiber line central office 60 can judge according to the characteristics of the network packet (such as label and IP) whether to transmit the network packet to the fixed access network optical fiber line central office private network edge host 90, the private network optical network equipment end private network edge host 20 or the Internet service 70. The following will continue to explain.

在步驟S230中，當固定接取網路光纖線路局端60判定終端設備10的網路封包是對應於固定接取網路光纖線路局端60的專網服務時，固定接取網路光纖線路局端60可傳送網路封包至固定接取網路光纖線路局端專網邊緣主機90。換言之，當固定接取網路光纖線路局端60判定網路封包的特徵（例如標籤與IP）是對應於固定接取網路光纖線路局端60的專網服務時，固定接取網路光纖線路局端60可傳送網路封包至固定接取網路光纖線路局端專網邊緣主機90。具體而言，當固定接取網路光纖線路局端60判定終端設備10的網路封包是對應於固定接取網路光纖線路局端60的專網服務時，專網服務節點模組63可傳送網路封包至軟體定義網路80。然後，軟體定義網路80可傳送網路封包至固定接取網路光纖線路局端專網邊緣主機90。更詳細而言，固定接取網路光纖線路局端專網邊緣主機90的數量可為多個。軟體定義網路80可經由IP來分流到特定的固定接取網路光纖線路局端專網邊緣主機90。在一實施例中，每個固定接取網路光纖線路局端專網邊緣主機90可以是VM虛擬環境模式，因此每個固定接取網路光纖線路局端專網邊緣主機90的IP可以不同。In step S230, when the fixed access network optical fiber line central office 60 determines that the network packet of the terminal device 10 corresponds to the private network service of the fixed access network optical fiber line central office 60, the fixed access network optical fiber line central office 60 can transmit the network packet to the fixed access network optical fiber line central office private network edge host 90. In other words, when the fixed access network optical fiber line central office 60 determines that the characteristics of the network packet (such as the label and the IP) correspond to the private network service of the fixed access network optical fiber line central office 60, the fixed access network optical fiber line central office 60 can transmit the network packet to the fixed access network optical fiber line central office private network edge host 90. Specifically, when the fixed access network optical fiber line central office 60 determines that the network packet of the terminal device 10 corresponds to the private network service of the fixed access network optical fiber line central office 60, the private network service node module 63 can transmit the network packet to the software-defined network 80. Then, the software-defined network 80 can transmit the network packet to the fixed access network optical fiber line central office private network edge host 90. In more detail, the number of the fixed access network optical fiber line central office private network edge host 90 can be multiple. The software-defined network 80 can be diverted to a specific fixed access network optical fiber line central office private network edge host 90 via IP. In one embodiment, each fixed access network optical fiber line central office private network edge host 90 may be in VM virtual environment mode, so the IP of each fixed access network optical fiber line central office private network edge host 90 may be different.

在固定接取網路光纖線路局端專網邊緣主機90接收網路封包之後，固定接取網路光纖線路局端專網邊緣主機90可處理此網路封包，並且將處理後的網路封包（經由軟體定義網路80、固定接取網路光纖線路局端60、固定接取網路光纖分配網路50以及光網路設備30）傳送至終端設備10。After the fixed access network optical fiber line central office private network edge host 90 receives the network packet, the fixed access network optical fiber line central office private network edge host 90 can process the network packet and transmit the processed network packet (via the software-defined network 80, the fixed access network optical fiber line central office 60, the fixed access network optical fiber distribution network 50 and the optical network device 30) to the terminal device 10.

在步驟S240中，當固定接取網路光纖線路局端60判定網路封包是對應於專網光網路設備端專網邊緣主機20的專網服務時，固定接取網路光纖線路局端60可傳送網路封包至專網光網路設備端專網邊緣主機20。換言之，當固定接取網路光纖線路局端60判定網路封包的特徵（例如標籤與IP）是對應於專網光網路設備端專網邊緣主機20的專網服務時，固定接取網路光纖線路局端60可傳送網路封包至專網光網路設備端專網邊緣主機20。具體而言，當固定接取網路光纖線路局端60判定網路封包是對應於專網光網路設備端專網邊緣主機20的專網服務時，固定接取網路光纖線路局端60可將網路封包轉換為光訊號。然後，固定接取網路光纖線路局端60可經由固定接取網路光纖分配網路50傳送光訊號至專網光網路設備40。In step S240, when the fixed access network optical fiber line central office 60 determines that the network packet corresponds to the private network service of the private network edge host 20 at the private network optical network equipment end, the fixed access network optical fiber line central office 60 can transmit the network packet to the private network edge host 20 at the private network optical network equipment end. In other words, when the fixed access network optical fiber line central office 60 determines that the characteristics of the network packet (such as the label and the IP) correspond to the private network service of the private network edge host 20 at the private network optical network equipment end, the fixed access network optical fiber line central office 60 can transmit the network packet to the private network edge host 20 at the private network optical network equipment end. Specifically, when the fixed access network optical fiber line central office 60 determines that the network packet corresponds to the private network service of the private network edge host 20 at the private network optical network equipment end, the fixed access network optical fiber line central office 60 can convert the network packet into an optical signal. Then, the fixed access network optical fiber line central office 60 can transmit the optical signal to the private network optical network equipment 40 via the fixed access network optical fiber distribution network 50.

然後，專網光網路設備40可將光訊號轉換為網路封包。詳細而言，專網固定接取網路光纖網路模組42可將光訊號轉換為網路封包。在一實施例中，專網固定接取網路光纖網路模組42可對網路封包執行VLAN處理操作。VLAN處理操作例如是VLAN轉換與QOS相關的功能。然後，專網家用閘道器模組41可對網路封包執行網路管理操作。網路管理操作例如是管理網路封包的標籤與IP。Then, the private network optical network device 40 can convert the optical signal into a network packet. Specifically, the private network fixed access network optical fiber network module 42 can convert the optical signal into a network packet. In one embodiment, the private network fixed access network optical fiber network module 42 can perform VLAN processing operations on the network packets. VLAN processing operations are, for example, functions related to VLAN conversion and QOS. Then, the private network home gateway module 41 can perform network management operations on the network packets. Network management operations are, for example, managing the labels and IPs of network packets.

然後，專網光網路設備40可傳送網路封包至專網光網路設備端專網邊緣主機20。在專網光網路設備端專網邊緣主機20接收網路封包之後，專網光網路設備端專網邊緣主機20可處理此網路封包，並且將處理後的網路封包（經由專網光網路設備40、固定接取網路光纖分配網路50以及光網路設備30）傳送至終端設備10。Then, the private network optical network device 40 can transmit the network packet to the private network edge host 20 at the private network optical network device end. After the private network edge host 20 at the private network optical network device end receives the network packet, the private network edge host 20 at the private network optical network device end can process the network packet and transmit the processed network packet (via the private network optical network device 40, the fixed access network optical fiber distribution network 50 and the optical network device 30) to the terminal device 10.

在步驟S250中，當固定接取網路光纖線路局端60判定網路封包不是專網服務時，上網服務節點模組62可傳送網路封包至網際網路服務70。在網際網路服務70接收網路封包之後，網際網路服務70可處理此網路封包，並且將處理後的網路封包（經由固定接取網路光纖線路局端60、固定接取網路光纖分配網路50以及光網路設備30）傳送至終端設備10。In step S250, when the fixed access network optical fiber line central office 60 determines that the network packet is not a private network service, the Internet service node module 62 can transmit the network packet to the Internet service 70. After the Internet service 70 receives the network packet, the Internet service 70 can process the network packet and transmit the processed network packet (via the fixed access network optical fiber line central office 60, the fixed access network optical fiber distribution network 50 and the optical network device 30) to the terminal device 10.

也就是說，如圖1及圖2所示，終端設備10的網路封包可傳送至（專網的）固定接取網路光纖線路局端專網邊緣主機90，也可被傳送至（專網的）專網光網路設備端專網邊緣主機20。或者，終端設備10的網路封包也可傳送至（非專網的）網際網路服務70。基此，終端設備10可存取多元的網路連線服務。特別是，與現有基於5G規範的專網服務相比，本發明並不需要額外設置MEC伺服器，且僅以VLAN或IP即可區分封包（即不需GTP-U訊務）。That is, as shown in FIG. 1 and FIG. 2 , the network packet of the terminal device 10 can be transmitted to the private network edge host 90 at the central office of the fixed access network optical fiber line (private network), and can also be transmitted to the private network edge host 20 at the private network optical network device end (private network). Alternatively, the network packet of the terminal device 10 can also be transmitted to the (non-private network) Internet service 70. Based on this, the terminal device 10 can access a variety of network connection services. In particular, compared with the existing private network services based on the 5G specification, the present invention does not require the additional setting of MEC servers, and packets can be distinguished only by VLAN or IP (i.e., no GTP-U service is required).

圖3是根據本發明的一實施例繪示的光網路設備30與固定接取網路光纖線路局端專網邊緣主機90之間的運作示意圖。請同時參照圖1及圖3。FIG3 is a schematic diagram showing the operation between an optical network device 30 and a fixed access network optical fiber line local end private network edge host 90 according to an embodiment of the present invention. Please refer to FIG1 and FIG3 at the same time.

在圖3的接取邊緣運算區中，固定接取網路光纖線路局端60的其中一個SNI端（Service Node Interface）可與匯集網路連接而提供上網的服務。另一方面，固定接取網路光纖線路局端60的另一個SNI端則可提供專網的邊緣運算服務。軟體定義網路80可經由IP來分流/導流到特定的固定接取網路光纖線路局端專網邊緣主機90來進行網路流量控制，並且可將固定接取網路下的邊緣運算服務經由光網路設備30提供給終端設備10。In the access edge computing area of FIG3 , one of the SNI terminals (Service Node Interface) of the fixed access network optical fiber line central office 60 can be connected to the aggregation network to provide Internet access services. On the other hand, another SNI terminal of the fixed access network optical fiber line central office 60 can provide edge computing services for the private network. The software-defined network 80 can be diverted/directed to a specific fixed access network optical fiber line central office private network edge host 90 via IP to control network traffic, and the edge computing services under the fixed access network can be provided to the terminal device 10 via the optical network device 30.

在本實施例中，固定接取網路的核心為固定接取網路光纖線路局端60與光網路設備30之間的光纖通訊。也就是說，可藉由固定接取網路光纖線路局端60的SNI端來傳送封包。另一方面，固定接取網路光纖線路局端60可連接軟體定義網路80以導流到特定的固定接取網路光纖線路局端專網邊緣主機90，以進行邊緣運算服務。專網服務的網路封包可以VLAN或IP在光網路設備30以及固定接取網路光纖線路局端60進行處理，故網路封包從SNI端到固定接取網路光纖線路局端專網邊緣主機90皆是un-tag封包，也就是一般Ethernet封包。另外，終端設備10到光網路設備30的封包也是un-tag的Ethernet封包。因此，無論是終端設備10與固定接取網路光纖線路局端專網邊緣主機90皆可彈性調整。In this embodiment, the core of the fixed access network is the optical fiber communication between the fixed access network optical fiber line central office 60 and the optical network equipment 30. In other words, packets can be transmitted through the SNI end of the fixed access network optical fiber line central office 60. On the other hand, the fixed access network optical fiber line central office 60 can be connected to the software-defined network 80 to be directed to a specific fixed access network optical fiber line central office private network edge host 90 to perform edge computing services. The network packets of the private network service can be processed by VLAN or IP in the optical network equipment 30 and the fixed access network optical fiber line central office 60, so the network packets from the SNI end to the fixed access network optical fiber line central office private network edge host 90 are all un-tag packets, that is, general Ethernet packets. In addition, the packets from the terminal device 10 to the optical network device 30 are also un-tagged Ethernet packets. Therefore, both the terminal device 10 and the fixed access network optical fiber line local end private network edge host 90 can be flexibly adjusted.

光網路設備30的WAN端可以是PON/GPON光纖介面，且光網路設備30的LAN端可以是1G（Gigabit）與10G的Ethernet介面。進一步而言，光網路設備30的LAN端可連接至具有不同邊緣運算需求的終端設備10。光網路設備30的第三層分流方法/第二層分流方法可控制終端設備10使用專網服務或者使用網際網路服務70。The WAN end of the optical network device 30 can be a PON/GPON optical fiber interface, and the LAN end of the optical network device 30 can be a 1G (Gigabit) and 10G Ethernet interface. Furthermore, the LAN end of the optical network device 30 can be connected to the terminal device 10 with different edge computing requirements. The third layer diversion method/second layer diversion method of the optical network device 30 can control the terminal device 10 to use a private network service or an Internet service 70.
