Description

Technical Field

[0001] This application relates to the field of network communication technology, and in particular to a load balancing method, apparatus and device based on edge cloud network. Background Technology

[0002] The 5G edge cloud network converged all-in-one machine is a platform that integrates 5G network and edge computing capabilities.

[0003] The 5G edge cloud-network converged appliance provides 5G private network services to industry users by sinking the 5G core network User Plane Function (UPF) network elements and adding Session Management Function (SMF) and Access and Mobility Management Function (AMF) network elements. Within the 5G edge cloud-network converged appliance, the UPF network elements forward user data through the N3 and N6 interfaces. Currently, the N3 and N6 interfaces forward user data via a single outgoing link. However, with the increasing number of users, this single outgoing link cannot meet their network bandwidth and stability requirements, resulting in poor transmission stability when the 5G cloud-network converged appliance forwards user data.

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0065] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0066] To facilitate understanding, let's first combine... Figure 1 The architecture of the edge cloud network system involved in the embodiments of this application will be described.

[0067] Figure 1 This is a schematic diagram of an edge cloud network system architecture provided for an embodiment of this application. Figure 1 As shown, the network system includes: terminal equipment, base stations, 5G cloud-network converged all-in-one machine, enterprise intranet, and public network unified data management (UDM) network elements.

[0068] In the aforementioned network system architecture, the base station establishes connections between terminal devices and the 5G cloud-network converged appliance to forward user data. The 5G cloud-network converged appliance includes at least UPF, SMF, and AMF network elements. The SMF and AMF network elements interface with the public UDM network element to send and receive signaling data. The UPF network element interfaces with the base station and the enterprise intranet, and forwards user data through the N3 and N6 interfaces.

[0069] In related technologies, the N3 and N6 interfaces forward user data through a single outgoing link. However, the bandwidth resources and operational stability of a single outgoing link are relatively poor, resulting in poor transmission stability when the 5G cloud-network converged appliance forwards user data.

[0070] To address the aforementioned technical issues, this embodiment utilizes multiple network interface cards (NICs) within the 5G cloud-network converged integrated server. These NICs are bonded together to create several bond interfaces. The 5G cloud-network converged integrated server uses these bond interfaces as the N3 and N6 interfaces, enabling the forwarding of user data through multiple egress links on the N3 and N6 interfaces. This improves the transmission stability of the 5G cloud-network converged integrated server when forwarding user data.

[0071] The technical solutions shown in this application will now be described through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; for the same or similar content, the description will not be repeated in different embodiments.

[0072] Figure 2 This is a flowchart illustrating a load balancing method based on an edge cloud network, provided as an embodiment of this application. Please refer to... Figure 2 The method may include:

[0073] S201. Receive the first data packet to be processed from the first Virtual Local Area Network (VLAN) sub-interface.

[0074] The execution entity in this embodiment is a server. Optionally, the server can be a 5G cloud-network converged integrated server.

[0075] The first data packet is the user data to be forwarded at the current moment. Optionally, the first data packet is a 5G data packet. The UPF network element can forward the first data packet.

[0076] In one possible implementation, the server includes at least two network interface cards (NICs), each NIC includes at least two ports, and the ports in different NICs are bound together.

[0077] For example, the server may include two two-port network interface cards (NICs). The two ports of each NIC are bonded to the two ports of the other NIC. Optionally, the cross-NIC bonding can be a bond binding.

[0078] like Figure 3 As shown, Figure 3 This is a schematic diagram illustrating cross-NIC binding as provided in an embodiment of this application. Please refer to [link / reference]. Figure 3The server includes network interface card (NIC) 1 and NIC 2. Both NIC 1 and NIC 2 have port 1 and port 2, meaning they are both two-port NICs. Port 1 of NIC 1 is bonded to port 1 of NIC 2, resulting in one bond interface. Port 2 of NIC 1 is also bonded to port 2 of NIC 2, resulting in one bond interface.

[0079] It should be noted that the cross-NIC bonding methods between NIC 1 and NIC 2 include, but are not limited to, [specific methods]. Figure 3 The provided binding method allows for cross-NIC port binding between two network interface cards (NICs). For example, port 1 of NIC 1 can be bonded to port 2 of NIC 2, and vice versa.

[0080] In one possible implementation, after configuring at least two network interface cards (NICs) on the server, the operational monitoring results of the at least two NICs on the server are obtained. Ports on the at least two NICs are then bound, and the at least two NICs are set to Dynamic Link Aggregation Control Protocol (LACP) mode. VLAN sub-interfaces are then configured for the ports on the at least two NICs on the server.

[0081] Specifically, after configuring at least two network interface cards (NICs) on the server, their operational status needs to be checked to confirm that they are functioning correctly and can establish dynamic LACP with the peer. For example, the peer could be a stacked switch. After binding at least two NICs on the server, the operating mode of the bound NICs needs to be selected. For example, within a containerized UPF container, the bond interface can be bound using the Data Plane Development Kit (DPDK) to enable the bound NICs to operate under dynamic LACP.

[0082] Within the containerized UPF container, two network cards are transparently transmitted into the container via the Kubernetes host-device container network interface (CNI). Then, bonds and dynamic LACP are configured within the Vector Packet Processing (VPP) framework.

[0088] bond add BondEthernet1 port0 / e / 0

[0089] setint state BondEthernet1 up

[0090] Furthermore, in this embodiment, VLAN sub-interfaces are configured on ports of at least two network interface cards (NICs) within the server to send and receive user data. The 5G cloud-network converged appliance needs to interface with internal network edge computing nodes. VLAN sub-interfaces are generated within the server using the VPP protocol stack, and VLAN data packets reachable from the edge computing nodes are encapsulated using DPDK.

[0091] It should be understood that, in addition to forwarding the aforementioned user data, the 5G cloud-network converged all-in-one machine can also send and receive signaling data.

[0092] In another possible implementation, in addition to the above-mentioned at least two two-port network cards, other network cards are also provided in the server.

[0093] Optionally, the server can bond ports of other network cards and use the bonded interface as the interface for sending and receiving signaling data for the 5G cloud-network converged all-in-one machine.

[0094] Optionally, a VLAN sub-interface can be configured within the server for the bonded interface to send and receive signaling data.

[0095] For example, when sending and receiving signaling data, the 5G cloud-network converged appliance can interface with public network UDM elements. VLAN isolation is achieved within the server's operating system by adding VLAN sub-interfaces to the bond port, and these VLAN sub-interfaces are then transparently transmitted to the corresponding 5G core network elements, such as SMF and AMF elements.

[0096] Specifically, add a bond sub-interface within the server's operating system, create the ` / etc / sysconfig / network-scripts / ifcfg-bond0.300` configuration file, and add the following configuration:

[0097] DEVICE = bond0.300

[0098] BOOTPROTO="static"

[0099] ONBOOT = yes

[0100] IPADDR = 172.30.30.75

[0101] NETMASK = 255.255.0.0

[0102] GATEWAY = 172.30.0.1

[0103] VLAN = yes

[0104] S202. Determine the type of the first data packet. The type of the first data packet is either an N3 data packet or an N6 data packet.

[0105] It should be understood that the UPF network element forwards user data through the N3 and N6 interfaces. The server can determine whether the first data packet is an N3 or N6 data packet based on the interface through which it receives the first data packet.

[0106] Specifically, if the first data packet is sent or received from the N3 interface, then the type of the first data packet is determined to be an N3 data packet. If the first data packet is sent or received from the N6 interface, then the type of the first data packet is determined to be an N6 data packet.

[0107] S203. Based on the type of the first data packet, determine the target interface among the interfaces of at least two network cards, and forward the first data packet through the target interface.

[0108] The target interface is the network interface card that ultimately forwards the first data packet.

[0109] In one possible implementation, after network interface card 1 and network interface card 2 are bonded across network interface cards, the resulting two bond interfaces can be used as the N3 and N6 interfaces of the 5G cloud-network converged integrated machine, respectively. The N3 and N6 interfaces can forward the first data packet.

[0110] It should be understood that for different first data packets, the server selects either the N3 interface or the N6 interface to forward the first data packet, and further selects a network interface card (NIC) port on the N3 interface or a NIC port on the N6 interface to forward the first data packet. That is, the target interface is either a NIC port on the N3 interface or a NIC port on the N6 interface.

[0111] The target interface can be determined as follows: Based on the type of the first data packet, determine the traffic splitting algorithm corresponding to the first data packet. Based on the traffic splitting algorithm corresponding to the first data packet, determine the target interface among the interfaces of at least two network interface cards (NICs).

[0112] Specifically, the server can select the corresponding traffic splitting algorithm based on the type of the data packet, and further determine one of the network interface cards (NIC) ports on the N3 or N6 interface as the target interface based on the traffic splitting algorithm. For example, the traffic splitting algorithm can be a hash-based traffic splitting algorithm based on the content contained in the first data packet.

[0113] The load balancing method based on edge cloud networks provided in this application embodiment involves configuring at least two network interface cards (NICs) in a server. The server performs bond binding on these two NICs, selecting dynamic link aggregation as the bonding mode. The two bonded interfaces are then used as the N3 and N6 interfaces of a 5G cloud-network converged appliance. This method enables user data forwarding via multiple egress links on the N3 and N6 interfaces, improving the transmission stability of the 5G cloud-network converged appliance when forwarding user data.

[0114] Based on any of the above embodiments, the following, in conjunction with Figure 4 This application provides a further detailed description of the load balancing method based on edge cloud networks.

[0115] Figure 4 This is a flowchart illustrating another load balancing method based on an edge cloud network provided in an embodiment of this application. Please refer to... Figure 4 The method may include:

[0116] S401: Receive the first data packet to be processed from the first VLAN sub-interface of the first virtual LAN.

[0117] S402. Determine the type of the first data packet. The type of the first data packet is either an N3 data packet or an N6 data packet.

[0118] It should be noted that the execution process of S401-S402 can be found in the execution process of S201-S202, and will not be repeated here.

[0119] S403. Determine the traffic splitting algorithm corresponding to the first data packet based on its type.

[0120] In this embodiment of the application, the splitting algorithm corresponding to the first data packet can be a hash splitting algorithm based on the content contained in the first data packet.

[0121] In one possible implementation, the traffic splitting algorithm corresponding to the first data packet can be determined as follows: if the type of the first data packet is N3, then the traffic splitting algorithm corresponding to the first data packet is determined to be a hash-based traffic splitting algorithm based on IP address (Layer 3, L3). If the type of the first data packet is N6, then the traffic splitting algorithm corresponding to the first data packet is determined to be a hash-based traffic splitting algorithm based on IP address and port number (Layer 3+4, L3+L4).

[0122] For example, assuming the 5G cloud-network converged appliance receives an N3 data packet, the server selects a hash-based traffic splitting algorithm based on the IP address. Assuming the 5G cloud-network converged appliance receives an N6 data packet, the server selects a hash-based traffic splitting algorithm based on both the IP address and the port number.

[0123] S404. Based on the traffic splitting algorithm corresponding to the first data packet, determine the target interface among the interfaces of at least two network cards.

[0124] In this embodiment of the application, for any N3 data packet or N6 data packet, the server can calculate the corresponding hash value according to the corresponding hash splitting algorithm, and further determine the target interface based on the hash value.

[0125] Specifically, if the traffic splitting algorithm corresponding to the first data packet is a hash-based traffic splitting algorithm based on the IP address, then the target interface is determined from the interfaces of at least two network interface cards (NICs) based on the IP address of the first data packet. If the traffic splitting algorithm corresponding to the first data packet is a hash-based traffic splitting algorithm based on both the IP address and the port number, then the target interface is determined from the interfaces of at least two network interface cards (NICs) based on both the IP address and the port number of the first data packet.

[0126] For example, assuming the first data packet is packet N3, the server selects a hash-based traffic splitting algorithm based on the IP address to calculate the hash value, and determines the target interface in interface N3 based on the hash value. Assuming the first data packet is packet N6, the server selects a hash-based traffic splitting algorithm based on both the IP address and port number to calculate the hash value, and determines the target interface in interface N6 based on the hash value.

[0127] The load balancing method based on edge cloud networks provided in this application uses two bond interfaces bound across network interface cards (NICs) as the N3 and N6 interfaces of a 5G cloud-network converged appliance, respectively. A corresponding hash-based traffic splitting algorithm is used at the N3 and N6 interfaces to determine the NIC interface used for forwarding user data. This method enables user data forwarding via dual-egress links on the N3 and N6 interfaces, improving the transmission stability of the 5G cloud-network converged appliance when forwarding user data.
