Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.

A method for obtaining segment routing over Internet Protocol version 6 data plane (SRv6) tunnel information of Internet Protocol version 6 segment routing, including sending, by a first network device, a request packet to a second network device, where the request packet is used to request to detect reachability of an SRv6 tunnel and obtain SRv6 tunnel information of the second network device, and the second network device is a network device on the SRv6 tunnel, receiving, by the first network device, a response packet from the second network device, where the response packet includes the SRv6 tunnel information of the second network device, and obtaining, by the first network device, the SRv6 tunnel information of the second network device based on the response packet.

A system includes a first device and a second device coupled to a link having one or more paths associated with transmitting a clock signal. The first device is to transmit a set of bits associated with a pattern via the one more paths. The set of bits are transmitted using a first clock signal having a first frequency less than a second frequency associated with data transmission operations. The second device is to receive the set of bits associated with the pattern, determine a number of pulses associated with the set of bits over a first period, and determine the number of pulses, associated with the set of bits, satisfies a predetermined condition relating to the number of pulses for the first period. The second device is to initiate a training of the link in response to determining the number of pulses satisfies the predetermined condition.

An endpoint computing device multi-network slice remediation/productivity system includes a core network system coupled to a RAN system and configured to allocate network slices and make them available for use in wireless communications via the RAN system. While operating in a pre-boot environment, an endpoint computing device determines that it is unable to transition to operating in a runtime environment and, in response, establishes a remediation network connection with a first network slice, and establishes a productivity network connection with a second network slice. While operating in a pre-boot environment and performing the remediation operations, the endpoint computing device then performs remediation operations via remediation wireless communications over the remediation network connection with the first network slice, and provides access to productivity application(s) that are configured to allow a user to perform productivity operations via productivity wireless communications over the productivity network connection with the second network slice.

PCIe devices installed in host computers communicating with service nodes can provide virtualized and high availability PCIe functions to host computer workloads. The PCIe device can receive a PCIe TLP encapsulated in a PCIe DLLP via a PCIe bus. The TLP includes a TLP address value, a TLP requester identifier, and a TLP type. The PCIe device can terminate the PCIe transaction by sending a DLLP ACK message to the host computer in response to receiving the TLP. The TLP packet can be used to create a workload request capsule that includes a request type indicator, an address offset, and a workload request identifier. A workload request packet that includes the workload request capsule can be sent to a virtualized service endpoint. The service node, implementing the virtualized service endpoint, receives a workload response packet that includes the workload request identifier and a workload response payload.

Disclosed are various embodiments for on-demand application-driven network slicing. In one embodiment, it is determined that an application implemented in a particular computing device has an increased quality-of-service requirement in order to send or receive data via a communications network. The increased quality-of-service requirement is greater than an existing quality-of-service provided to the application by the communications network. The application sends a request that causes capacity in a network slice having the increased quality-of-service requirement in the communications network to be allocated for the application. The data is transmitted to or from the application using the network slice.
