摘要： An address space recommendation method is provided, including: obtaining an address space recommendation request sent by a client for a first VPC, wherein the address space recommendation request includes an identifier of a first alliance relationship; and determining, in response to the address space recommendation request, a first address space different from a second address space corresponding to a second VPC, wherein the first VPC and the second VPC have the first alliance relationship; and outputting the first address space to the client. Because the first address space that does not have an address conflict with another VPC in an alliance relationship may be automatically recommended for a VPC, a user does not need to manually configure an address space for the VPC.

摘要： The present disclosure describes a system and method for deconflicting locally administered medium access control addresses (LAMAs). An apparatus includes a memory and a processor communicatively coupled to the memory. The processor receives a request for a client device to use a LAMA and determines that the LAMA is reserved for future use by a first access point. The processor also transmits to the client device a message denying connectivity to the client device using the LAMA.

摘要： Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.

摘要： A device implementing the subject system may include at least one processor configured to receive, by a first system process, a first network address that corresponds to a domain name that was resolved by a second system process, the resolving having been responsive to a resolution request therefor by an application process. The at least one processor may be further configured to receive, by the first system process, a second network address for which a network connection was opened by the application process. The at least one processor may be further configured to, responsive to determining that the application process opened a network connection for a network address for which the application process did not provide, to the second system process, a resolution request for the corresponding domain name, provide, by the first system process, an indication of the network address in conjunction with an indication of the application process.

摘要： Techniques are disclosed for scaling an IP address in overlay networks without using load balancers. In certain implementations, an overlay IP address can be attached to multiple compute instances via virtual network interface cards (VNICs) associated with the multiple compute instances. Traffic directed to the multi-attached IP address is distributed across the multiple compute instances. In some other implementations, ECMP techniques in overlay networks are used to scale an overlay IP address. In forwarding tables used for routing packets, the IP address being scaled is associated with multiple next hop paths to multiple network virtualization devices (NVDs) associated with the multiple compute instances. When a particular packet directed to the overlay IP address is to be routed, one of the multiple next hop paths is selected for routing the packet. This enables packets directed to the IP address to be distributed across the multiple compute instances.

摘要： Disclosed is a system and a method for configuring an IP device to be discoverable to a client device over a local network having a DHCP server for assigning dynamic IP addresses. The method includes obtaining a dynamic IP address assigned to the IP device upon completion of boot process for the IP device; checking if a static IP address has been set for the IP device; determining if the dynamic IP address and the static IP address are in a same subnet of the local network; implementing the static IP address set for the IP device, if the dynamic IP address and the static IP address are in the same subnet of the local network; and implementing the dynamic IP address assigned to the IP device, if the dynamic IP address and the static IP address are not in the same subnet of the local network.

摘要： Apparatus, methods, and systems for tuple space search-based flow classification using cuckoo hash tables and unmasked packet headers are described herein. A device can communicate with one or more hardware switches. The device can include memory to store hash table entries of a hash table. The device can include processing circuitry to perform a hash lookup in the hash table. The lookup can be based on an unmasked key include in a packet header corresponding to a received data packet. The processing circuitry can retrieve an index pointing to a sub-table, the sub-table including a set of rules for handling the data packet. Other embodiments are also described.

摘要： Network address configuration in distributed node networks can be performed and managed. A network management component (NMC) can determine a group of hooks, and an order of respective hooks of the group in a network address management stack, that can be utilized to configure a network address on an interface associated with a group of nodes based on characteristics associated with a node or interface configuration system. NMC can execute the group of hooks in order at runtime to facilitate configuration of the network address on the interface. NMC can execute respective threads of a hook stack in parallel for respective network addresses. NMC can modify a hook(s) in a hook group in response to a change in characteristics associated with the node or interface configuration system. NMC can determine another group of hooks and hook order that can be executed to remove the network address from the interface.

摘要： A method for supporting configurable producer network function (NF) Internet protocol (IP) address mappings includes, at an NF repository function (NRF), receiving, from a requesting node, a request message for network address and/or service information of a producer NF. The method further includes determining, from the request message, at least one consumer NF parameter. The method further includes using the at least one consumer NF parameter, a producer NF IP address mapping rule. The method further includes, in response to locating the producer NF IP address mapping rule, determining, using the producer NF IP address mapping rule, an IP address to return to the requesting node. The method further includes generating a response message including the IP address and transmitting the response message to the requesting node.

摘要： The present disclosure relates to network connection methods and devices for connecting a terminal device to a network through a network access device. The network access device may include a processor and a connection configuration component. The processor receives a connection request from the terminal device. The processor also authenticates the terminal device based on the connection request, and obtains a verified Internet protocol (IP) address from the connection configuration component. The processor further transmits the verified IP address to the terminal device after the terminal device is authenticated, wherein the terminal device is configured to be connected to the network by using the verified IP address.
