Configuration rules can be received through the service API interface and configured, so that the problem that manual configuration is easy to make mistakes is avoided.

The following describes each part of the network virtual switching system in this exemplary embodiment in more detail with reference to the drawings and examples.

In this example embodiment, referring to fig. 1, the architecture of a network virtual switching system 10 may include: a controller 101, a data control unit 102, and a data forwarding unit 103; in addition, a data storage unit may be included.

The controller 101 may be configured to receive a configuration rule of the service system through the service API interface, and generate a corresponding control signal according to the configuration rule.

The data control unit 102 may be configured to manage the data forwarding unit according to the control signal.

The data forwarding unit 103 may be configured to create a forwarding table entry according to the configuration information, and perform data distribution using the data forwarding table entry.

The data storage unit 104 may be configured to store the forwarding entries, configuration information, and data flows of the network device.

In this example embodiment, the architecture of the network Virtual switching system may implement a service vSwitch (Virtual Switch). The controller 101 may be connected with a plurality of service API interfaces, and may be connected with different service systems upstream through the service API interfaces, so as to implement service processing on the plurality of service systems. The controller 101 receives the configuration rule issued by the service system through the service API interface, generates a control signal according to the configuration rule, and sends the control information to the data control unit 102.

The data control unit 102 may distribute configuration information, traffic forwarding rules, and collect operation status information of the network device to the data forwarding unit 103 according to the received control signal. Specifically, the data control unit 102 may integrate the gRPC (Google Remote Procedure Call ) service end 1021, the gRPC (Google Remote Procedure Call, google remote procedure call) client 1024, the UDP (User Datagram Protocol ) client 1022, and the FTP (File Transfer Protocol ) client 1025 based on the VPP (Vector Packet Processing ) framework. The UDP client can be used for reporting network element port flow, user flow and general alarm information; the FTP client may be responsible for pulling the full profile to the network element control center for fault recovery. The gRPC server can be used for receiving the control signal to process the traffic forwarding service. The gRPC client can be used for reporting network element heartbeat, important alarm information and user state change information. Furthermore, in some example embodiments, the data control unit may also include a TCP client 1023 and a Unix socket interface 1026; the TCP client 1023 may be utilized to maintain a TCP long connection with the VPP, and is responsible for service configuration and status information collection. Inter-process communication may also be implemented using Unix socket interface 1026.

The data forwarding unit 103 is configured with a port connected to the network device, and may be configured to receive the management instruction issued by the data control unit 102, create a forwarding table according to the configuration information, and forward traffic between the ingress and egress ports of the network device by using the data forwarding table, so as to perform data distribution. For example, the data forwarding unit may be configured with a DPDK (Data Plane Development Kit ) port

The data storage unit 104 may interact with the data control unit 102 and the data forwarding unit 103, respectively, and is used for storing forwarding entries, configuration information and data flows of the network device. In particular, the data storage unit may employ a relational database, such as a MysqlDB database; and the data persistence storage is realized, so that the service processing and the local data recovery are facilitated.

In some exemplary embodiments, the data forwarding unit described above may be implemented in the form of a VNF (virtual network function, virtualized network function) architecture. In particular, DHCP, DPDK, PPPOE, MPLS, NAT, vxlan, l layer 2/l3 forwarding may be supported. In addition, the VNF may be deployed using a docker engine, and the data volume mode is used to mount the required persistent files into the host, including mysql storage files, VPP-agents, and VPP configuration files. The advantages of strong portability, quick start-up and deployment are realized by using containerized deployment for the vSwitch.

The data forwarding unit may be configured to process the packet processing flow into a plurality of flow nodes, so as to process the packet by using the plurality of flow nodes. Specifically, the data forwarding unit may adopt a packet processing graph (Packet Processing Grap), abstract the packet processing flow into node, and multiple nodes form the packet processing graph. The nodes are loosely coupled, and the whole frame is highly modularized, flexible and easy to expand. The VPP has built in various nodes, node graphs can be reorganized according to own wish, and the nodes can be developed by a plug-in mechanism and inserted into the node graphs.

In addition, the data forwarding unit may also use a vectorization message processing technology, where each flow processes N messages at a time (N is 256 at maximum), and then the N messages are handed to the next flow for processing. The vector message processing utilizes the time locality characteristic of data message processing to divide a batch of messages into a group, and if the I-cache hits, the batch of messages hit; otherwise, the batch of messages is missed. And when the data Packet is not hit, preheating is carried out for the I-cache through a first Packet-1 in the Packet Vector, and then the obtained instruction in the cache can be repeatedly executed for a subsequent data Packet in the Vector Packet. Thus, the processing performance of the rest messages in the Packet Vector can directly reach the limit, so that the cache miss time of one message is shared in the whole message Packet, and the processing overhead of a single message is obviously reduced.

In some exemplary embodiments, the network virtual switching system described above may be used to implement access vSwitch (virtual switch), or traffic vSwitch. The access vSwitch can be used for realizing a network flow access point, receiving the flows of the terminal and the network, and performing scheduling management on the flows. The traffic vSwitch may be used for an access point that accepts traffic related traffic, forwarding traffic between the access vSwitch and the traffic system.

The reverse nat node flow may include: DPDk-input- & gt ethernet-input- & gt ip 4-sv-reflection-feature- & gt nat44-out2 in- & gt vxlan 4-encap- & gt ip 4-rewrite- & gt inf output

The vxlan4-input node may be used for vxlan header parsing to shift the data pointer to the user message.

The nat44-pre-in2out node can be applied to the unpacking of the vxlan message, wherein the inner layer message is a two-layer message, the Ethernet header is identified, the two-layer vlan header is used for shifting the data pointer to the three-layer header of the user message, the samba message is identified or the common message is identified, and the next hop node is designated for distributing the message.

The nat44-in2out-output node can be used for nat fast path processing, identifying vni+qinq of a message, inquiring nonstandard NATless, taking session as source IP and port replacement, and designating the next node IP-lookup; the absence of session designates the next node as the nat slow path processing node.

The nat44-in2out-output-slow node can be used for nat slow path processing nodes, identify vni+qinq of a message, acquire a user natIP according to a forwarding rule, calculate available ports, establish an in-and-out direction session, make source IP and port replacement, and designate the next node IP-log up.

The ip4-lookup node may be used to look up a routing table to determine whether the next node message is sent to the ip4-arp or ip4-rewrite.

The ip4-rewrite node can be used for ip4 header encapsulation.

The nat44-out2in node can be used for a nat report processing node, and based on the message inquiry to the outbound direction session, the nat44-out2in node can be used for carrying out original source IP and port replacement, and when the nat is not marked, the original two-layer header is packaged, and the next node vxlan4-encap is designated.

The vxlan4-encap node can be used for vxlan header encapsulation.
