30 results about "Primary Identifier" patented technology

Primary identifiers. A primary identifier is a single attribute that is assigned as the primary key. You must specify one primary item identifier for the enterprise to facilitate data exchange and avoid duplicate resolutions.

Identifying a potential ddos attack using statistical analysis

Embodiments can identify requests that may be tied to a DDOS attack. For example, the primary identifiers (e.g., a source address) of requests for a network resource (e.g., an entire website or a particular element of the website) can be tracked. In one embodiment, a statistical analysis of how often a particular source address (or other primary identifier) normally makes a request can be used to identify source addresses that make substantially more requests. A normal amount can correspond to an average number of request that a source address makes. According to some embodiments, a system can use statistical analysis methods on various request data in web server logs to identify potential attacks and send data concerned potential attacks to an HBA system for further analysis.

Real-time creation method for virtual channel link of avionics system

The invention discloses a real-time creation method for a virtual channel link of an avionics system, and aims to provide a virtual channel link creation method which is simple, reliable, rapid, flexible and low in complexity. The invention is realized through the following technical scheme: the method comprises the following steps: based on a high-speed serial RapidIO bus, sending a virtual channel link creation request to node management software, taking a channel name as a primary identifier of a virtual channel link between the nodes of the two communication parties, and injecting the virtual channel name and virtual channel related parameters of the nodes of the two communication parties through an external micro control unit (MCU) or each communication node debugging interface; then,after the node management software stores the virtual channel creation request information initiated by each communication node, matching the consistency of the related parameters of the receiving party and the transmitting party; and according to a consistency judgment result, issuing the virtual channel related configuration information to the related communication nodes, waiting for each related node to return an acknowledgement character ACK signal, and determining whether virtual channel link creation work is completed or not.

Real-time creation method of virtual channel link in avionics system

The invention discloses a method for creating a virtual channel link in an avionics system in real time, and aims to provide a method for creating a virtual channel link that is simple, reliable, fast, flexible, and low in complexity. The present invention is realized through the following technical solutions: based on the high-speed serial RapidIO bus, a virtual channel link creation request is sent to the node management software, the channel name is used as the primary identifier of the virtual channel link between the nodes of the two communication parties, and the external micro-controller The unit MCU or the debugging interface of each communication node, inject the virtual channel name and virtual channel related parameters of the nodes of both communication parties; then, the node management software stores the virtual channel creation request information initiated by each communication node, and the related parameters of the sender and receiver. According to the consistency judgment result, the related configuration information of the virtual channel is sent to the relevant communication nodes, and wait for each relevant node to return the confirmation character ACK signal to determine whether the creation of the virtual channel link is completed.

Method of locating mobile communicating objects within a communications network, comprising the transmission of location identifiers by repeaters and server updates

The invention relates to a mobile communicating object (A) belonging to a communications network and comprising processing means (PM). According to the invention, when a communication has been established with another communicating object (S) belonging to the network, the aforementioned processing means generate a repeater (Fi) at each site (Hi) through which they pass. Moreover, when the repeater is generated, the processing means associate a timing counter (CTF) therewith and configure said repeater such that: (i) it can store an identifier that is representative of the location of the next repeater (F(i+1)) or site (H(i+l)) in the chain of repeaters to which it belongs; and (ii) at the end of a selected duration of time, it transmits the location identifier of the next repeater (F(i+1)) or site (S(i+l)) to at least one location server (SL) in the network, so that it stores said identifier together with the primary identifier of the mobile object (A). Preferably, once a repeater has addressed the location identifier, the relay activity thereof is terminated and, if the repeater does not belong to another chain, it is removed so that it no longer consumes resources.

Codebook restructure, differential encoding/decoding, and scheduling

A method and apparatus for feedback of channel information characterizing a wireless transmission between a base station and a mobile station over a communications channel. The method involves, at the base station, receiving a primary identifier identifying a cluster associated with a channel response generated by a mobile station, receiving a differential identifier identifying channel response member within the cluster identified by the primary identifier, and locating in a codebook of predetermined channel responses a predetermined channel response identified by the primary identifier and the differential identifier. The predetermined channel responses in the codebook are grouped in a plurality of clusters in accordance with a correlation criterion, each cluster including a plurality of predetermined channel response members. The method also involves generating a control signal for controlling transmissions to the mobile station in accordance with the located predetermined channel response. The method also involves, at the mobile station, determining a channel response for at least one carrier frequency received at the mobile station, and locating in a codebook of predetermined channel responses a predetermined channel response that is a closest match to the determined channel response, causing the mobile station to transmit a primary identifier identifying a cluster associated with the located predetermined channel response to the base station, and causing the mobile station to transmit a differential identifier identifying the located predetermined channel response member within the cluster identified by the primary identifier.
