[0032] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawing. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawing, it should be understood that the present invention may be embodied in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0033] With reference to Fig. 1 and Fig. 2, Fig. 1 shows a schematic diagram of a multi-mode routing switching architecture according to an embodiment of the present application, and Fig. 2 shows a schematic diagram of a multi-mode switching network and a unified packet control network according to an embodiment of the present application.
[0034] The embodiment of the present application provides a multi-mode routing switching architecture of a space network based on a unified packet control plane, which includes a multi-mode switching controller 1 and a plurality of data forwarding nodes. The multi-mode switching controller 1 is used for controlling a data switching network and forming a plurality of forwarding tables based on an information status and/or diversified service requirements of the data switching network. The multi-mode switching controller is used for performing the following steps based on the plurality of forwarding tables to realize forwarding: receiving node information uploaded by a data forwarding node, and generating a network topology structure based on the node information of the connected data forwarding node to generate a routing table according to the network topology structure, the routing table being used for : representing a possible forwarding path between the data forwarding node and other data forwarding nodes in the network topology structure; sending the routing table to the data forwarding node, so that after receiving a data packet, the data forwarding node determines the forwarding path based on the routing table and according to identification mode information of the data packet, so as to forward the data packet.
C72P8LU 31.03.2023
[0035] The plurality of data forwarding nodes correspond to the plurality of forwarding tables one to one and are used for data forwarding. 0103088
[0036] It needs to be understood that in the process flow of data exchange, the multi-mode switching controller 1 can collect the status information of the whole network and establish and maintain the plurality of forwarding tables, so that respective data forwarding nodes can select a space data exchange system according to the plurality of forwarding tables to complete the forwarding of data information, establish different virtual networks for different applications, and meet differentiated service quality requirements.
[0037] In an optional example, the plurality of forwarding tables include a laser forwarding table, a microwave forwarding table, a channel forwarding table and a packet forwarding table.
The data forwarding node may select the space switching system according to the laser forwarding table, the microwave forwarding table, the channel forwarding table or the packet forwarding table to complete data forwarding. Further, the packet forwarding table includes an
IP forwarding table, a label forwarding table and an identification forwarding table.
[0038].In an optional example, the multi-mode switching controller is configured with a plurality of routing algorithms corresponding to the identification mode information. and the "multi-mode switching controller is further used for:
[0039] analyzing, when receiving the data packet uploaded by the data forwarding node, the data packet to acquire the identification mode information of the data packet and corresponding feature information.
[0040] Identification modes in the embodiment of the application may include: an IP identification mode based on TCP/IP, an NDN identification mode with resource content as an addressing mode, an SINET identification mode focusing on the separation of identities and locations, and a Geo-spatial IP (GEOIP) identification mode for communication within the scope of target coordinates or target geographic locations. The feature information corresponding to the identification mode information represents the data information for routing calculation and path selection under the identification mode, such as a source address and destination address information of the data packet.
[0041] Performing data analyzing on the data packet to acquire the identification mode information of the data packet and the feature information corresponding to the identification mode information may include analyzing a mac address of the data packet. The mac address contains a type field, which can be used for distinguishing different identification modes, for example, 0x86DD for Ipv6 and 0x8624 for Ndn. When different identification modes are identified, corresponding identification mode processing rules are triggered, and the feature 6 information carried in the data packet is extracted according to the identification mode processing rules for routing calculation and path selection. LUT03098
[0042] According to the identification mode information of the data packet, corresponding network status information is acquired and the corresponding routing algorithm is determined.
[0043] Different network status information is acquired for the identification mode information of different data packets. For example, when the identification mode is the IP identification mode, the acquired network status information includes a link state, a node IP address, a network topology state, etc.; and when the identification mode is the NDN identification mode, the acquired network status information includes a cache content name, a resource registration node. etc, and the network status information of other modes is not enumerated again. Different identification modes trigger different routing algorithms to carry out calculation on the acquired information. The specific routing algorithm is not limited herein and can be set as needed.
[0044] According to the determined routing algorithm, the feature information corresponding to the identification mode information and the network status information, the forwarding path of the data packet is determined based on the routing table. The feature information corresponding to the identification mode information and the network status information may be calculated according to the routing algorithms corresponding to different identifications, to determine the optimal path.
[0045] The forwarding path of the data packet is sent to the corresponding data forwarding node. :
[0046] Routing information may be sent in the form of a flow table, and the sending the routing information of the data packet to the corresponding data forwarding node may include taking the routing information such as port information as action domain parameters of the flow table. In an optional example, the multi-mode switching controller is further used for: determining flow rule data of the corresponding identification mode according to the identification mode information of the data packet; generating the flow table according to the forwarding path of the data packet and the flow rule data; and sending the flow table to the corresponding data forwarding node. Timers may be set on each flow table, and after the timeout, the flow table is deleted, thus achieving the effect of saving a storage space.
[0047] In an optional example, when the path selection instruction is received from a user, the forwarding path of the data packet is directly determined by the selection instruction. For example, a manual path selection mode may be set to provide support for the user to select the routing path, which further improves the selection flexibility of network routing. 7
C72P8LU 31.03.2023
[0048] In one example, each data forwarding node supports any one or more of space data, 103098 exchange systems such as laser forwarding, microwave switching, channel switching and : packet switching. Therefore, each data forwarding node can be in one-to-one correspondence with the laser forwarding table, the microwave forwarding table, the channel forwarding table or the packet forwarding table so as to perform data conversion.
[0049] In an optional example, the plurality of forwarding tables may form a plurality of switching networks, and the plurality of switching networks include any one or more of a laser switching network, a microwave switching network, a channelized switching network and a packet switching network. Therefore, the multi-mode switching controller 1 can be used for controlling any one or more of the laser switching network, the microwave switching network, the channelized switching network and the packet switching network.
[0050] Furthermore, the laser switching network is a virtual network formed according to the laser forwarding table, and performs transparent forwarding of laser data. The microwave switching network is a virtual network formed according to the microwave forwarding table, and performs transparent forwarding of microwave data. The channelized switching network is a virtual network formed according to the channelized forwarding table, and performs semi- transparent forwarding of channelized data. The packet switching network is a virtual network formed according to the packet forwarding table, and performs data forwarding according to an on-board processing switching system of ATM, IP or MPLS.
[0051] The technical solution according to the present embodiment will be described below in combination with specific application scenarios.
[0052] Application scenario 1
[0053] Taking into consideration the form of space and ground heterogeneous service applications, that is, traditional applications plus emerging applications, military applications plus civil applications, as well as the differentiated service quality requirements of different applications, the architecture of the space network needs to support dynamic and elastic reconfiguration, and can establish different virtual networks for different applications to meet the differentiated service quality requirements.
[0054] Referring to the idea of Software Defined Network (SDN), the multi-mode routing switching architecture of "laser switching + microwave switching + channelized switching + packet switching" for diversified services is illustrated in Fig. 1.
[0055] The unified packet control network is constructed by using the multi-mode switching controller, and respective forwarding nodes form the multi-mode switching network by supporting the plurality of switching systems such as laser switching, microwave switching, 8
C72P8LU 31.03.2023 channelized switching and packet switching. In the unified packet control network, the status information of the whole network and the requirements of diversified services are acquired 105098 through the multi-mode switching controller, the virtual networks are established according to the service requirements, and the forwarding tables are formed and sent to respective forwarding nodes. In the multi-mode switching network, the forwarding node selects the designated space data exchange system according to the received forwarding table, and forwards the data information according to the forwarding table rule.
[0056] The specific multi-mode switching controller receives the node information uploaded by the data forwarding node, and generates the network topology structure based on the node information of the connected data forwarding node, so as to generate the routing table according to the network topology structure. After that, the multi-mode switching controller sends the routing table to the data forwarding node, so that the data forwarding node determines the forwarding path based on the routing table and according to the identification mode information of the data packet after receiving the data packet.
[0057] The multi-mode data switching can give full play to the advantages of various switching systems and meet the application requirements to the maximum extent.
[0058] The multi-mode routing switching architecture constructs the plurality of virtual networks through the unified multi-mode switching controller and the forwarding nodes supporting the plurality of switching systems, supports the systems such as laser switching, microwave switching, channel switching and packet switching, and meets the requirements of different services on differentiated service quality. For example, the microwave switching or channelized switching is adopted for the requirements of large bandwidth relay applications, the packet switching may be used for Internet access services. optical switching may be used for data backhaul of a large data volume, and so on.
[0059] Application scenario 2
[0060] In the multi-mode routing switching architecture of a space network, the separation of network control and a forwarding function is realized according to the concept of SDN. As shown in Fig. 2, the multi-mode routing switching architecture of a space network includes a control plane and a forwarding plane, in which the control plane is a joint packet control network, the forwarding plane is a multi-mode switching network. The forwarding plane supports the routing switching systems such as microwave switching, laser switching, channelized switching and packet switching. Each switching system corresponds to one forwarding table (Forwarding Information Base (FIB)) or routing table (Routing Information
Base (RIB)). For example, in Fig. 2, IP forwarding (switching) corresponds to the routing 9
C72P8LU 31.03.2023 table (RIB). channel forwarding corresponds to the label forwarding table LFIB, etc., which 103008 will not be described in detail here. The multi-mode routing switching architecture of a space network in the example has the characteristics of flexibility and multi-granularity. so as to meet the differentiated and personalized service guarantee requirements of different services.
[0061] The microwave switching and the laser switching both belong to an on-board transparent forwarding switching system. Under such a switching system, on-board devices do not perform processing such as modulation/demodulation on received electromagnetic signals, but only perform frequency conversion on the physical signals according to preset rules, and then forward the signals to a ground station.
[0062] The channel switching is a semi-transparent forwarding technology with some on- board processing capabilities, adopts a digital processing mode, realizes the analysis and synthesis of on-board signals with a non-uniform filter bank by using a flexible on-board channelized filtering technology, and supports information interaction between any frequency band and any bandwidth on board and flexible cross-beam interaction.
[0063] The packet switching belongs to an on-board processing switching system. By a series of processing units such as demodulation, decoding, encoding and modulation for the signal, the signal is demodulated and regenerated, which can remove a noise superimposed on the signal in a line and improve the transmission quality of the whole communication link.
[0064] In the case of coexistence of various switching systems, the traditional forwarding plane is improved by using the technology such as P4/POF. By programming data processing behaviors of an underlying device, the user can dynamically configure the network by programming the network according to needs, and the functional requirements of the user are achieved. Further, various data formats, including AOS, MAC, SCPS-NP, IPv4, IPv6, IDP,
MPLS and the like, are compatible, protocol unawareness is realized, and the network flexibility is greatly improved. i
