Abstract: Methods and server systems for computing fraud risk scores for various merchants associated with an acquirer described herein. The method performed by a server system includes accessing merchant-related transaction data including merchant-related transaction indicators associated with a merchant from a transaction database. Method includes generating a merchant-related transaction features based on the merchant-related indicators. Method includes generating via risk prediction models, for a payment transaction with the merchant, merchant health and compliance risk scores, merchant terminal risk scores, merchant chargeback risk scores, and merchant activity risk scores based on the merchant-related transaction features. Method includes facilitating transmission of a notification message to an acquirer server associated with the merchant.

Abstract: A method for Xx/Xn interface communication is disclosed, comprising: at an Xx/Xn gateway for communicating with, and coupled to, a first and a second radio access network (RAN), receiving messages from the first RAN according to a first Xx/Xn protocol and mapping the received messages to a second Xx/Xn protocol for transmission to the second RAN; maintaining state of one of the first RAN or the second RAN at the Xx/Xn gateway; executing executable code received at an interpreter at the Xx/Xn gateway as part of the received messages; altering the maintained state based on the executed executable code; and receiving and decoding an initial Xx/Xn message from the first RAN; identifying specific strings in the initial Xx/Xn message; matching the identified specific strings in a database of stored scripts; and performing a transformation on the initial Xx/Xn message, the transformation being retrieved from the database for stored scripts, the stored scripts being transformations.

Abstract: In one embodiment, a supervisory device designates a particular networking device among a set of networking devices as a seed device and one or more interfaces of the seed device as discovery interfaces. The supervisory device coordinates, starting from the one or more discovery interfaces of the seed device, discovery of a Layer 2 topology of the set of networking devices, by designating one or more interfaces of a discovered networking device as discovery interfaces. The supervisory device converts, starting from at least one of the network devices farthest from the seed device in the Layer 2 topology and ending with the seed device, links of the Layer 2 topology into Layer 3 links, to form an underlay network.

Abstract: In one embodiment, contextual service mobility in an enterprise fabric network environment (e.g., overlay and underlay networks) provides for moving of the location of a service being applied to packets with minimal updates to the mapping database. The mapping database is used to convert addresses of the overlay network to physical network and service addresses. The mapping database provides contextual lookup operations on the same destination address of a packet being forwarded in the overlay network to provide different results. The contextual lookup operations provide for a packet to be forwarded to a service node or its intended destination depending on the current context. In one embodiment, the enterprise fabric network uses Locator/ID Separation Protocol (LISP), a network architecture and set of protocols that uses different overlay and underlay namespaces and a distributed mapping database for converting an overlay address to an underlay address.

Abstract: The invention enables an enterprise to manage changes to computing infrastructure through an online change management system. The invention enables authorized users to logon to the system, view a personal and holistic calendar, create reports, modify change management records, attach files or other artifacts to change management records. The invention also provides business rules which can be employed online for service which then invokes various system components to create a workgroup and workflow according to predefined business rules.
