Abstract: This disclosure describes techniques for providing a distributed scalable architecture for Network Address Translation (NAT) systems with high availability and mitigations for flow breakage during failover events. The NAT servers may include functionality to serve as fast-path servers and/or slow-path servers. A fast-path server may include a NAT worker that includes a cache of NAT mappings to perform stateful network address translation and to forward packets with minimal latency. A slow-path server may include a mapping server that creates new NAT mappings, depreciates old ones, and answers NAT worker state requests. The NAT system may use virtual mapping servers (VMSs) running on primary physical servers with state duplicated VMSs on different physical failover servers.

Abstract: Non-personal network attributes of a user's network connection are detected. A user's physical location is classified as being onsite or remote based upon the non-personal network attributes. Connectivity performance information is generated indicative of a performance of a user device in connecting with the host computing system over the network, and a control signal is generated to surface performance information through an administrative system.

Abstract: A method of remediating system services relies on a first dependency graph with super nodes, to each of which a set of system services are assigned, and second dependency graphs, each of which represents dependencies among the system services that are in one of the sets. The method includes the steps of: comparing an actual configuration state of the system services to a desired configuration state of the system services to identify configurations that are in drift; identifying system services corresponding to the configurations that are in drift; determining an order of updating configurations of the identified system services using the first and second dependency graphs; and applying the desired configurations of the identified system services in the order determined, wherein after the configurations of an identified system service are updated, the system service executes with the updated configurations.

Abstract: A system for detecting a root cause of an exception error in a task flow in a distributed network receives communication data exchanged among servers. The system determines whether each message is received by a respective server based on acknowledgement data that indicates whether each message is received by a respective server. The system determines the sequence of the messages communicated between the servers. The system determines that a first server has reported an exception error that indicated the first server did not receive a message from a second server. The system determines that the second server is associated with a root cause of the exception error in response to determining that the second server did not send the message to the first server.

Abstract: Systems, methods, and devices are disclosed for establishing sessions over a network. A query can be sent, from a mobile device to an authoritative DNS server, requesting a session over a network. In response to the query, a list of available communication protocol options can be received from the authoritative DNS server. A specific communication protocol can be selected from the list of available communication protocol options, where the specific communication protocol is selected based on one or more performance metrics. A connection with a gateway device can then be initiated using the selected specific communication protocol.

Abstract: Systems and methods are provided for aggregating media content in an electronic messaging application starts with server system receiving from first client device a first media content item and a selection of client devices including second client device. Server system generates a group including first client device and client devices in the selection. Server system causes a group selectable item including a new item indication to be displayed by client devices included in the group. In response to receiving a first signal that indicates that a first portion of the group selectable item has been selected, server system causes the first media content item to be displayed by second client device. Once the first media content item is displayed for a period of time, server system removes the new item indication from the group selectable item and causes the group selectable item to be displayed by second client device. Other embodiments are disclosed.

Abstract: In an example, a network switch is configured to natively act as a high-speed load balancer. Numerous load-balancing techniques may be used, including one that bases the traffic “bucket” on a source IP address of an incoming packet. This particular technique provides a network administrator a powerful tool for shaping network traffic. For example, by assigning certain classes of computers on the network particular IP addresses, the network administrator can ensure that the traffic is load balanced in a desirable fashion. To further increase flexibility, the network administrator may apply a bit mask to the IP address, and expose only a portion, selected from a desired octet of the address.

Abstract: Techniques for utilising multiple network interfaces for a cloud shell are provided. The techniques include receiving, by a computer system, a command to execute an operation by the computer system, the command being received from a router via a primary virtual network interface card (vNIC). The computer system may execute the operation, generating an output of the operation. The techniques also include transmitting, by the computer system, a message comprising the output of the operation to a shell subnet via a secondary vNIC, the secondary vNIC being configured for unidirectional transmission from the computer system to the shell subnet. The shell subnet may be configured to transmit the output of the operation to an external network via a network gateway.

Abstract: Some embodiments provide a method for an MFE, in a first datacenter, to implement an LN spanning the first datacenter and a set of additional datacenters. The method stores records that each map one or more LN addresses for DCNs belonging to the LN and operating in the first datacenter to a different TEP address. The method stores an additional record that maps addresses for DCNs connected to a particular LFE of the LN and operating in the additional datacenters to a group of TEP addresses corresponding to LN gateways that handle data traffic for the particular LFE between the first datacenter and the additional datacenters. Upon receiving a data message with a destination address corresponding to a DCN connected to the particular LFE and operating in one of the additional datacenters, the method uses the additional record to identify a TEP address for encapsulating the data message.

Abstract: A content replacement system sends a content item with one or more content replacement parts to be consumed by a user of a client device. The content item is further associated with an interaction pattern that corresponds to a particular user interaction and a defined action that is to be executed by the client device when the particular user interaction is performed on the client device. While the content replacement part is played on the client device, one or more sensors of the client device acquire data regarding user interactions performed by the user on the client device. The acquired data is processed to determine whether the user has performed a user interaction that matches the interaction pattern. Upon detecting a match, the client device sends a notification to the content replacement system indicating that the match has occurred and further executes the defined action.
