Abstract: An information processing method includes, when determining that a target node in a to-be-processed chassis is used as a management node of the to-be-processed chassis, obtaining a virtual address and assigning the virtual address to the target node, notifying a subnet corresponding to the to-be-processed chassis with the virtual address, and performing communication with a target programmable module of the to-be-processed chassis through the target node and management on data of the to-be-processed chassis. The virtual address is used to inform that the target node is the management node.

Abstract: Techniques are described for learning an unknown virtual network information, such as an virtual Internet Protocol (IP) address, of a pod in a virtual network. In some examples, a virtual router executing at a computing device may receive an Address Resolution Protocol (ARP) packet from a virtual execution element in the virtual network, the virtual execution element executing at the computing device. The virtual router may determine, based at least in part on the ARP packet, whether virtual network information for the virtual execution element in a virtual network is known to the virtual router. The virtual router may, in response to determining that the virtual network information of the virtual execution element in the virtual network is not known to the virtual router, perform learning of the virtual network information for the virtual execution element.

Abstract: Some embodiments of the invention provide a method for deploying network elements for a set of machines in a set of one or more datacenters. The datacenter set is part of one availability zone in some embodiments. The method receives intent-based API (Application Programming Interface) requests, and parses these API requests to identify a set of network elements to connect and/or perform services for the set of machines. In some embodiments, the API is a hierarchical document that can specify multiple different compute and/or network elements at different levels of compute and/or network element hierarchy. The method performs automated processes to define a virtual private cloud (VPC) to connect the set of machines to a logical network that segregates the set of machines from other machines in the datacenter set. In some embodiments, the set of machines include virtual machines and containers, the VPC is defined with a supervisor cluster namespace, and the API requests are provided as YAML files.

Abstract: A method for resolving address resolution protocol (ARP) requests includes, at an ARP listening entity of a computer network, receiving an ARP request for a MAC (media access control) address of a destination entity having a specified IP (internet protocol) address, the ARP request received from a requesting entity, wherein a design of the computer network prevents broadcast of the ARP request to the destination entity. An ARP response is transmitted to the requesting entity, the ARP response specifying a response MAC address to facilitate transmission, by the requesting entity, of a data packet targeting the response MAC address, and wherein prior to receipt of the data packet at the destination entity, the specified IP address is associated with an actual MAC address of the destination entity according to an IP-to-MAC mapping.

Abstract: One embodiment of the present invention facilitates address resolution protocol (ARP) resolution in an extended subnet. A gateway of a first segment of the extended subnet can determine that a layer-2 address corresponding to a layer-3 destination address of a packet is locally unavailable. The gateway can then determine whether a respective egress interface of an ARP request for the layer-3 destination address is associated with a layer-2 subnet extension from the first segment to a second segment of the extended subnet. The extension can provide a common layer-2 broadcast domain comprising the first and second segments with a same default gateway layer-3 address. If the egress interface is associated with the extension, the gateway can insert a layer-3 address of a first endpoint associated with the extension as a source protocol address in the ARP request. The gateway can send the modified ARP request via the egress interface.

Abstract: Embodiments of this application provide a method and an apparatus for determining virtual machine VM migration. The method includes: after a VM is migrated, sending a gratuitous ARP packet or a RARP packet to an in-migration VTEP device; obtaining, by the VTEP device, a MAC address of the VM, searching an ARP cache table based on the MAC address, and obtaining an IP address of the VM; and constructing an ARP unicast request packet by using the IP address as a destination IP address, and if the VTEP device receives an ARP response packet sent by the VM for the ARP unicast request packet, determining that the VM is migrated.

Abstract: A data migration method and an apparatus are applied to a scenario in which a user plane gateway communicating with a terminal is changed from a source user plane gateway to a target user plane gateway. The target user plane gateway receives an address of the terminal from a control plane gateway, obtains an Ethernet data packet based on the address of the terminal, and sends the Ethernet data packet to an Ethernet interface, so that a switch obtains the Ethernet data packet through the Ethernet interface, and updates a MAC address table based on the Ethernet data packet.

Abstract: Techniques are disclosed for session-based routing of multipoint Open Systems Interconnection (OSI) Model Layer-2 (L2) frames of an L2 network extended over Layer-3 (L3) networks. In one example, L2 networks connect a source device to an ingress router and receiver devices to egress routers. An L3 network connects the ingress and egress routers. The ingress router receives, from the source device, a multipoint L2 frame destined for the receiver devices. The ingress router forms, for each egress router that is connected to at least one multipoint receiver device, a unicast L3 packet for the L2 frame and forwards the unicast L3 packet to the egress router. Each egress router generates, in response to receiving the unicast L3 packet, the multipoint L2 frame and forwards, to the receiver devices, the multipoint L2 frame.

Abstract: Systems, methods, and computer-readable media are provided for protecting a network from network discovery by an unknown or unauthenticated device. A network element, according to one implementation, is arranged in a communication network and includes an interface device configured to enable communication with an unknown network device. The network element also includes a memory system configured to store first and second sets of network information. The first set of network information includes fake information about the network and is configured to deceive the unknown network device before a procedure is performed for analyzing the authentication of the unknown network device. The second set of network information includes real information about the network. In some cases, the first set of network information may be provided to the unknown network device via the interface device before performing the procedure for analyzing the authentication of the unknown network device.
