Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.

This application provides a data transmission method and apparatus, and relates to the field of communications technologies. The method includes: obtaining a plurality of code block streams; distributing, based on a preset multiplexing sequence, code blocks in the plurality of code block streams by slots, to form a single, interleaved code block stream from the plurality of code block streams; and segmenting and encapsulating the single, interleaved code block stream, to generate at least one frame. By utilizing time division duplexing techniques, a data transmission delay of the code block streams can be reduced.

Technologies are disclosed for monitoring network traffic using traffic mirroring. According to some examples, traffic mirroring allows customers to monitor traffic at different sources within a VPC. For example, a source may be any Elastic Network Interface (ENI) in their VPC, including elastic network interfaces (ENIs) on virtual machine instances, Network Address Translation (NAT) Gateways, Load Balancers, VPC endpoints, Internal Gateways, Transit Gateways, and more. Filters can be utilized to determine the network traffic to mirror. A customer may also configure to monitor real-time traffic with a monitoring appliance of their choice. With traffic mirroring, data traffic may be identified and sent to one or more target devices. Customers may monitor traffic within a VPC for content inspection, forensic analysis, troubleshooting, record keeping, and the like. Using traffic mirroring, customers can replicate VPC traffic, along with full payload data, without installing and managing agents on virtual machine instances.

An example method may include identifying upload packets at a VPN client operating on a client device, which include a header with a destination server as the destination field and the client device as the source field, adding, via the VPN client, an additional header identifying the client device in an additional source field and identifying an interconnect server center (ISC) device in an additional destination field, to create modified upload packets, receiving the modified upload packets from the client device at the ISC device, replacing, via the ISC device, the additional source field of the modified upload packets with a new additional source field identifying the ISC device and replacing the additional destination field of the modified upload packets with a new additional destination field identifying a VPN server to create further modified upload packets, and forwarding the further modified upload packets to the VPN server for routing to the destination server.

Disclosed are a method and a system for EVPN message forwarding, a non-transitory computer-readable storage medium and a terminal device. The method includes: reading an Ethernet segment identifier (ESI) label from a message if the message contains the ESI label after receiving the message from an upstream device, and obtaining a port for an Ethernet segment (ES) corresponding to the ESI label according to the ESI label; reading an egress port for the message; and discarding the message if the port for the ES corresponding to the ESI label obtained according to the ESI label is the same as the egress port for the message.

A Peripheral Component Interconnect Express (PCIe)-based data transmission method and apparatus includes a first node that encapsulates data into a transaction layer packet (TLP) and then sends the TLP to a second node, where the TLP includes a packet header part, a first field and a second field of the packet header part that are used to indicate first encapsulation information, and the first encapsulation information includes a data type of the data and at least one encapsulation parameter corresponding to the data type.t The first field and the second field are used to indicate the information required for transmitting the data, so that the endpoints can communicate with each other even if the root is not used.

A network device receives an IPv4-in-IPv6 packet. An IPv6 header is removed. A first DSCP value in a TC field and a second DSCP value in a ToS field is stored in a database. The IPv4 packet is forwarded upstream and a return IPv4 packet is received. The returned IPv4 packet is encapsulated to form an IPv6 packet. The first DSCP value and the second DSCP value are retrieved from the database. Based on the at least one policy, the second DSCP value is inserted into an IPv4 ToS field and into an IPv6 TC field, the retrieved second DSCP value is inserted into the IPv4 ToS field and the first DSCP value is inserted into the IPv6 TC field, or the first DSCP value is inserted into the IPv6 TC field and into the IPv4 ToS field. The network device then forwards the IPv6 packet downstream.

The method is for the transfer of data of a message subdivided in fragments from a first intermediary electronic processing unit (43) to a second intermediary electronic processing unit (45); before the transfer, the first unit (43) receives the data encapsulated in the payload of data packets of the TCP type from a sender electronic processing unit (41) and decapsulates them; after the transfer, the second unit (45) encapsulates data in the payload of data packets of the TCP type and transmits them to a recipient electronic processing unit (47); the transfer takes place by means of data packets of the UDP type; the first unit (43) also inserts in the payload (32) of UDP packets; a first data field (C1) containing an identifier of a connection between the sender unit (41) and the recipient unit (47), a second data field (C2) containing an identifier of the message to be transferred, and a third data field (C3) containing a number that identifies the position of a fragment within the message to be transferred.
