A system configured to track network slicing operations includes memory and processing circuitry configured to select a network slice instance (NSI) from a plurality of available NSIs based on an NSI type specified by a client node. The available NSIs uses virtualized network resources of a first network resource provider. The client node is associated with the selected NSI. The utilization of the network resources by the plurality of available NSIs is determined using an artificial intelligence (AI)-based network inferencing function. A ledger entry of associating the selected NSI with the client node is recorded in a distributed ledger, which further includes a second ledger entry indicating allocations of resource subsets to each of the NSIs based on the utilization.

Abstract: A method for determining a Quality of Experience associated with a real-time communication session between user devices includes monitoring the real-time communication session and determining at least one quality indicator of the Quality of Experience, at least one first performance indicator of a Quality of Service, and at least one second performance indicator of the Quality of Service. Based on the quality indicator and the first performance indicator, the method determines, among a family of correlation functions indicative of the correlation between the Quality of Experience and a Quality of Service in respect of a generic real-time communication session, a correlation function which is indicative of the correlation between the Quality of Experience and the Quality of Service in respect of the monitored real-time communication session. Then the method applies the first performance indicator and the second performance indicator to the correlation function to determine said Quality of Experience.

Abstract: In one embodiment, a domain name system (DNS) server processes a DNS query based on a policy statement that is attached to the DNS query. Upon receiving the DNS query, the DNS server executes one or more commands specified in the policy statement to generate a query state. The query state controls DNS resolution behavior that the DNS server implements as part of processing the DNS query. The DNS server then performs one or more DNS resolution operations based on DNS query and the query state to generate a response. Advantageously, because the semantics of the policy statement are encapsulated within the policy statement, the policy statement enables a client to unambiguously control DNS resolution behavior. By contrast, conventional DNS resolution guidance mechanisms that rely on DNS servers to infer policies based on client data may not reflect the preferences of the clients.

Abstract: A method supports service level agreement monitoring in a software defined network. The software defined network has forwarding elements and a software defined network controller for controlling the forwarding elements. Data flows are transmitted between a first end-path forwarding element, of the forwarding elements, and a second end-path forwarding element, of the forwarding elements, via at least one intermediate forwarding element, of the forwarding elements. The software defined network controller configures the intermediate forwarding element such that a probe triggering packet is generated based on local information of the intermediate forwarding element. The software defined network controller configures at least one of the first end-path forwarding element or the second end-path forwarding element such that an end-to-end probing is triggered based on receiving the probe triggering packet. The end-to-end probing is performed in order to detect a service level agreement violation.

The service probabilistically determines whether or not the connection has become degraded and replies to the application with information indicative of the same.

Abstract: An illustrative latency service system identifies, in response to a request by a user equipment (UE) device for performance of a distributed computing service, a latency performance level to which the UE device is subscribed. The system obtains real-time latency performance data for a distributed computing network that is to perform the distributed computing service for the UE device in response to the request, and, based on the real-time latency performance data, determines a characteristic of a geographic zone in which the UE device is located. The characteristic is associated with latency performance that the distributed computing network is capable of providing in the geographic zone. Based on the latency performance level and the characteristic of the geographic zone, the system arranges for the performance of the distributed computing service for the UE device by the distributed computing network. Corresponding methods and systems are also disclosed.

Abstract: A Voice over Internet Protocol (VoIP) system is configured for direct communications between remote computing devices in a peer-to-peer configuration. Voice data from the communication is marked such that the voice data from the different endpoints can be combined into a unified audio stream. An authentication may be accomplished automatically prior to text or audio communication between a customer and a service agent. In some embodiments, authentication is accomplished automatically by authentication of the remote access device or accomplished by asking the customer questions. A single authentication of the remote access device may be used to authenticate a service request transferred between service agents. The authentication of the remote device may include, for example, use of a personal identification number, a fingerprint, a photograph, and/or a hardware identifier.

Abstract: Server devices operating on the Internet or another wide area network (WAN) are able to locate client devices using address information obtained from a shared location. Client devices initially determine their own network address information and submit the determined information for a priori storage at the shared location on the WAN. Each server device, in turn, contacts a message service or the like to establish a persistent data connection that is maintained between the message service and the server device over time. After the client device stores its own address information, the client initiates contact with the server via the message service having the previously-established persistent connection. Upon receipt of the instruction from the message service, the server is able to retrieve the client's previously-stored address information from the WAN storage and use the information to establish a connection with the client.

Abstract: A redirection device and method, relating to identification of a data server capable of delivering content to a terminal, initiated by the transfer to a second name server of a second domain of a message for obtaining an identifier of the data server in the second domain received from the terminal. Following this transfer, the second name server sends a redirection message to a first domain, including a delegation chain including first data for redirection from the second domain to the first domain. The chain is updated recursively with the redirections between domains added by respective name servers until a name server is able to provide an identifier of the data server.

Virtualization agents detect and monitor the virtualization structure of virtualized hardware used in the execution infrastructure, operating system agents deployed to individual operating systems monitor resource utilization, performance and communication of processes executed by the operating system and transaction agents deployed to processes participating in the execution of transactions, providing end-to-end transaction trace and monitoring data describing individual transaction executions.

Abstract: A system and a method are disclosed for receiving, by a server, based on input by a user, a request to lock a set of data. Responsively, the server modifies the set of data to be locked, and determines whether an amount of bandwidth required to index the locked data exceeds a threshold. Responsive to determining that the amount of bandwidth exceeds the threshold, the server instructs a secondary server to allocate bandwidth to index a first portion of the locked data. The server indexes a second portion of the locked data in parallel with the secondary server indexing the first portion of the locked data, and generates an index by collating the indexed first and second portions of the locked data. The server receives a search request for a portion of the locked data, and retrieves the portion of the locked data based on referencing the index.

Abstract: The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.

Abstract: A home computing cloud (HCC) supports one or more Internet of Things (IoT) devices, possibly with different connectively protocols, in a local environment. The HCC often reduces the amount of data traffic sent to a public computing cloud (PCC) by locally processing collected device data rather than by sending the device data to the PCC for processing. This approach reduces the amount of data traffic sent over the network, improves data privacy and helps to maintain a desired quality of service level. In order to do so, the HCC may download an appropriate data analytic model from the PCC, train the model, execute the trained model to obtain prediction information from collected IoT device data, and upload the trained model to the PCC. Alternatively, the HCC and PCC may execute sub-models of the analytic model and exchange the outputs of the sub-models with each other.

Abstract: Disclosed are various embodiments for automating data center builds through the use of service proxies. A proxy is configured in a testing computing environment to receive service calls for a plurality of first services in the testing computing environment. The proxy forwards the service calls to at least one corresponding instance of the plurality of first services not in the testing computing environment. One or more second services in the testing computing environment that generate the service calls for the plurality of first services are then tested. The service calls are handled by the proxy during testing.

Abstract: Described herein are systems and methods for host multihoming with no state synchronization between top-of-rack (ToR) switches coupled to multiple hosts. ToR switches of a multi-homing system share a virtual MAC address and respond to Address Resolution Protocol (ARP) requests and/or Neighbor Discovery (ND) solicitations for a default gateway IP address from the host with the virtual MAC address. Ports on a ToR switch may be configured either with a static ARP and/or ND entry, or be configured to learn via a discovery protocol. The lightweight host multihoming system may have modified flooding behavior, ARP/ND handling, and data path forwarding. ARP/ND traffic from a host is processed by a ToR switch, while other multicast traffic may be discarded. Embodiments of the host multihoming system provide a lightweight solution for software implementation with minimal changes imposed on the host or network design.
