A method for predicting fraudulent call activity is provided. The method includes receiving one or more datasets indicating call activity corresponding to a phone number, and analyzing the one or more datasets to identify unusual call activity. The method further includes generating a fraud prediction, based at least in part on the identified unusual call activity, that the phone number will be used for fraud.

In one aspect, a computerized method includes the step of providing process monitor in a Gateway. The method includes the step of, with the process monitor, launching a Gateway. Daemon (GWD). The GWD runs a GWD process that implements a Network Address Translation (NAT) process. The NAT process includes receiving a set of data packets from one or more Edge devices and forwarding the set of data packets to a public Internet. The method includes the step of receiving another set of data packets from the public Internet and forwarding the other set of data packets to the one or more Edge devices. The method includes the step of launching a Network Address Translation daemon (NATD). The method includes the step of detecting that the GWD process is interrupted; moving the NAT process to the NATD.

Example methods are provided for a network management entity to perform weighted multipath routing configuration in a software-defined networking (SDN) environment. The method may comprise the network management entity obtaining state information associated with the multiple second nodes that provide multiple respective paths for first node to reach a destination network; and based on the state information associated with the multiple second nodes, assigning the multiple second nodes with respective multiple weights. The method may also comprise generating and sending control information specifying the multiple weights to the first node. The control information is to cause the first node to perform weighted multipath routing to distribute egress packets that are destined for the destination network over the multiple second nodes based on the multiple weights.

Techniques for flow rate based load balancing are described. In one embodiment, a method includes receiving a packet associated with a packet flow at an ingress top-of-rack switch in a spine-leaf network. The method includes determining identification information for the packet flow, including a source and a destination. Based on the identification information, the method includes determining an instantaneous flow rate for a first path through the network from the source to the destination. The method also includes comparing the instantaneous flow rate to an average flow rate. Based on the comparison between the instantaneous flow rate to the average flow rate, the method includes assigning the packet flow to one of the first path or a second path.

Systems, methods, and computer-readable media for controlling data transmission in TCP subflows of a MPTCP connection based on monetary cost. A low cost link and a high cost link of TCP subflows of a MPTCP connection formed between a first MPTCP peer and a second MPTCP peer can be identified. A congestion level on the low cost link can be determined based on feedback from a TCP congestion control mechanism for the MPTCP connection. Further, whether to send a data packet over the low cost link of the high cost link based on the congestion level on the low cost link can be determined. As follows, the data packet can be sent over the low cost link connection if it is determined to send the data packet over the low cost link.

A method includes receiving, from an origin computing node, a first communication addressed to multiple destination computing nodes in a processor interconnect fabric, measuring a first set of one or more communication metrics associated with a transmission path to one or more of the multiple destination computing nodes, and for each of the destination computing nodes, based on the set of communication metrics, selecting between a multicast transmission mode and unicast transmission mode as a transmission mode for transmitting the first communication to the destination computing node.

Systems and methods include, at a first Border Gateway Protocol (BGP) speaker node which interconnects two autonomous systems, receiving an advertisement containing available bandwidth on one or more links between the two autonomous systems from a second BGP speaker node; and, for a BGP best path calculation between the two autonomous systems at the first BGP speaker node, selecting a link of the one or more links based on the available bandwidth on the link from the advertisement. At the first BGP speaker node, the systems and methods can further include determining bandwidth on the one or more links; and transmitting an updated advertisement based on the determined bandwidth. The bandwidth can be determined based on a configurable sampling interval. The transmitted update can be provided if the determined bandwidth has changed from a previous value by more than a configurable threshold.

Then determining at the first network device the number of available processing cores on the second network device and generating a plurality of tunneling sessions between the first network device and the second device. Associating the received data with a particular tunneling session and then generating translation data unique to the associated tunneling session prior to encapsulating the received data with the translation data. Finally, transmitting the encapsulated data to the second network device and processing the transmitted encapsulated data received at the second network device with a particular processing core based on the received translation data.
