Systems, methods, and computer-readable media provide for collection of statistics relating to network traffic between virtual machines (VMs) in a network. In an example embodiment, a virtual switch hosted on a physical server provides network address information of VMs deployed on the physical server to a virtual switch controller. The controller collects this network address information from each virtual switch under its control, and distributes the aggregate address information to each switch. In this manner, the controller and each switch within the controller's domain can learn the network address information of each VM deployed on physical servers hosting switches under the controller's control. Each virtual switch can determine a classification of a frame passing through the switch (e.g., intra-server, inter-server and intra-domain, or inter-domain traffic), and statistics relating to the traffic. In an example embodiment, the virtual switch controller can collect the statistics from each switch within its domain.

In one embodiment, a method includes receiving a plurality of uniform resource identifiers (URI's) associated with a particular domain. Each of the URI's identifies a content page comprising one or more signature elements. The method further includes, for each URI in the plurality of URI's, successively testing the URI to identify a core of the URI and any unnecessary elements of the URI. The core of the URI is sufficient to retrieve a version of the content page including all of its signature elements. The method additionally includes, for each URI in the plurality of URI's, updating a set of rules based on the identified core and the identified unnecessary elements. The set of rules establishes a normalized version of the URI.

A communication method is provided. The method includes transmitting a network address assignment request to the network address translation entity after establishing a general packet radio service (GPRS) tunneling protocol (GTP) tunnel between the first user-plane function entity and the second user-plane function entity, such that the network address translation entity assigns a network address to the GTP tunnel, notifying the network address assigned by the network address translation entity to the GTP tunnel to the central data network, controlling a data packet to be transmitted by the edge service node to the central data network to be transmitted through the GTP tunnel, the network address translation entity replacing a source address of the data packet with the network address, and transmitting the data packet to the central data network after the data packet arrives at the network address translation entity.

A system for providing a Domain Name System (DNS) service may include providing an agent for installation on a subscriber device. The subscriber device may be connected to the DNS service via an entry point device. The system includes receiving, from the agent, agent data indicative of a subscriber identifier and a unique identifier associated with the entry point device. The system may then determine, based on the agent data, a current Internet Protocol (IP) address associated with the entry point device and associate the unique identifier with the subscriber identifier. The system may then dynamically map the subscriber identifier to the current IP address and provide DNS service to the subscriber device based on the current IP address.

A system and method are provided for a network device for use with a client device having a hostname and a MAC address. The network device contains a memory that has a second hostname and a second MAC address stored within the memory. The second MAC address corresponds to the second hostname. The memory also contains a processor configured to execute instructions stored on the memory to cause the network device to: receive, from the client device, the hostname and the MAC address; determine whether the MAC address is randomized; provide an instruction to the client device to inform a user of the client device that the client device hostname is registered when the hostname matches the second hostname and the MAC address is randomized.

When a failed connection is detected from a first radio unit (RU) to the cellular site router (CSR), activation of an existing backup cabled connection from the first RU to the CSR through a cabled connection between the first RU and a second RU of the cellular telecommunications tower may be performed. In one example, a first RU and second RU each have two physical network ports. The activation of the existing backup cabled connection from the first RU, via the second RU, to the CSR may include causing the first RU to enter from a normal operating mode into an Open Radio Access Network (O-RAN) cascade operating mode to attempt to attain network connectivity for the first RU using the second physical network port of the first RU.

An available network address is acquired from a network address resource pool associated with the application system according to determination that a workload at a set of network ports of the application system meets a predetermined extension condition, the network address resource pool comprising network addresses configured to be assigned to the application system. A network port available at the application system is selected. A communication channel for accessing the application system is established based on the network address and the network port. According to determination that an access request for accessing the application system is received from an access device, the access request is responded to by using the communication channel. The communication channel provided by the application system to the access device can be dynamically adjusted in real time according to a workload related to data access of the application system.

Disclosed is an improved approach for managing floating/virtual IP addresses in a virtualization system. Where a bare metal cloud provider does not provide adequate facilities to implement broadcast operations, the approach would capture broadcast packets, and from the captured packets, generate calls to the cloud provider to implement configuration changes to reflect the changes desired by the broadcast packets.
