20090190511 | Method and apparatus for detecting wireless data subscribers using natted devices - A system and method for network based detection of wireless data subscribers using network address translation devices is provided. The method includes identifying a minimum number of devices showing the same internet protocol address. Packet identification sequences may include port numbers or internet protocol identification numbers. The method continues with grouping these applications by their packet identification sequences and applying detection logic where detection logic yields a conclusion that there are multiple host computers when a set of applications appears in a plurality of packet identification sequences. This method is particularly useful when internet protocol addresses are dynamic, as opposed to static. This method overcomes previous embodiments known in the art by being able to account for and work with live traffic, which enables real time detection. | 07-30-2009 |
20110075667 | LAYER 2 SEAMLESS SITE EXTENSION OF ENTERPRISES IN CLOUD COMPUTING - Various embodiments relate to a Cloud Data Center, a system comprising the Cloud Data Center, and a related method. The Cloud Data Center may include a logical customer edge router to send packets between addresses in a private enterprise network and addresses in a logical network within a cloud network using Layer 2 protocol and MAC addressing. The logical network may have resources, known as virtual machines, allocated to the private enterprise network and may share a common IP address space with the private enterprise network. A directory at the Cloud Data Center may correlate the enterprise IP addresses of virtual machines with a MAC address, cloud IP address, and a location IP address within the logical network. The Cloud Data Center may double encapsulate packets with MAC, cloudIP, and locIP headers, when sending a packet to a destination in the logical network. | 03-31-2011 |
20110075674 | SCALABLE ARCHITECTURE FOR ENTERPRISE EXTENSION IN A CLOUD TOPOLOGY - Various embodiments relate to a Cloud Data Center, a system comprising the Cloud Data Center, and a related method. The Cloud Data Center may include a logical customer edge router to send packets between addresses in a private enterprise network and addresses in a logical network within a cloud network. The logical network may have resources, known as virtual machines, allocated to the private enterprise network and may share a common IP address space with the private enterprise network. A directory at the Cloud Data Center may correlate the enterprise IP addresses of virtual machines with a cloud IP address and a location IP address within the logical network. The Cloud Data Center may double encapsulate packets with two specified headers, a cloudIP and locIP header, when sending a packet to a destination in the logical network. | 03-31-2011 |
20110078303 | DYNAMIC LOAD BALANCING AND SCALING OF ALLOCATED CLOUD RESOURCES IN AN ENTERPRISE NETWORK - Various exemplary embodiments relate to a workload distribution system for an enterprise network extended in to a cloud network and a related method. The enterprise network may include a series of servers in a private enterprise network and a scalable series of servers in a cloud network. The enterprise network may employ one or more load balancers in both a private enterprise network and cloud network that are connected to each series of servers to distribute work amongst the servers in both networks based on criteria such as overall system performance and costs. The enterprise network may also employ one or more controllers to scale the number of cloud servers allocated to the enterprise network based on the system workload and other user-defined criteria, such as revenue generated per work request. | 03-31-2011 |
20110090941 | Method And Apparatus For Retransmitting Information - To address the need for new techniques that are able to address overlapping channel collisions various embodiments are described. They are used to introduce the concept of retransmission-permutation, in which a bit-to-subcarrier assignment is permuted ( | 04-21-2011 |
20130070741 | METHOD AND APPARATUS FOR SCHEDULING TRANSMISSIONS FOR ANTENNA ARRAYS - Embodiments of the claimed subject matter provide a method and apparatus for scheduling transmissions for an antenna array. One embodiment of the method includes scheduling a subset of a plurality of packets for concurrent transmission over an air interface to a corresponding subset of a plurality of wireless-enabled terminals. The subset is selected based on information indicating locations of the subset of the plurality of wireless-enabled terminals. This embodiment of the method also includes concurrently transmitting the subset of the plurality of packets using a plurality of antennas. | 03-21-2013 |
20130089009 | METHOD AND APPARATUS FOR INTERFERENCE CANCELLATION FOR ANTENNA ARRAYS - Embodiments of the claimed subject matter provide methods and apparatuses for interference cancellation. One embodiment of a method includes estimating, for an antenna in an antenna array including a plurality of antennas, interference parameters using analog signals received at the antenna on each of a plurality of subcarriers. Each interference parameter is associated with one of a plurality of symbols transmitted to one of a plurality of users on one of the plurality of subcarriers. This embodiment also includes canceling interference from analog signals received by the antenna on the plurality of subcarriers using the estimated interference parameters. | 04-11-2013 |
20130151429 | SYSTEM AND METHOD OF DETERMINING ENTERPRISE SOCIAL NETWORK USAGE - According to an embodiment, a computing system includes at least one computing device including a processor configured to use a logistic regression model to provide an indication of a relationship between a user's position within an enterprise and how the user interacts with other users of an enterprise social network. | 06-13-2013 |
20130262656 | SYSTEM AND METHOD FOR ROOT CAUSE ANALYSIS OF MOBILE NETWORK PERFORMANCE PROBLEMS - A method and system for identifying causes of performance metric changes in a network by selecting, from a pool of network event counters, a plurality of candidate counters relevant to a performance metric; grouping the candidate counters into clusters of similar counters; selecting, from each cluster, one or more representative counters; and fitting the selected representative counters to a model of the performance metric to determine thereby a set of representative counters most relevant to the performance metric. | 10-03-2013 |
