Publication number: 20180225357Abstract: An approach for self-improving classification. The approach receives sensor data of a machine, wherein the sensor data is collected during operation of the machine. The approach defines one or more categories, wherein each category of the one or more categories is associated with one or more parameters. The approach determines whether the sensor data matches one or more parameters of a first category of the one or more categories. Responsive to a determination that the sensor data matches the one or more parameters of the first category, the approach classifies the sensor data into the first category. The approach applies a first category label to the sensor data, wherein the first category label is associated with the first category.Type: ApplicationFiled: February 15, 2018Publication date: August 9, 2018Inventors: Nancy A. Greco, Bong Jun Ko, Maroun Touma, Dinesh C. Verma, David A. Wood

Patent number: 9806946Abstract: Traffic redirection methods include determining a quality-affective factor comprising a quality-affective factor in an existing connection between a client and a server in a network. The quality-affective factor is compared to a threshold to determine whether the connection would benefit from a network processing function. A router is reconfigured to exclude the middlebox from the connection, if the connection would not benefit from the network processing function and if the middlebox is already present in the connection, to cease operation of the middlebox on the connection. The router reconfiguration is delayed until the connection is idle.Type: GrantFiled: August 30, 2016Date of Patent: October 31, 2017Assignee: International Business Machines CorporationInventors: Seraphin B.

Publication number: 20130054831Abstract: File traffic redirection from a core server to a network edge. A request for a file from a target system is received from one or more requestors in direct communication with the computer. The request includes a host name of the target system. If the host name is not locally resolvable, requesting a resolution of the host name from a domain name resolution process external to the computer. An Internet protocol address of the target system is received from the domain name resolution process, and all subsequent file requests by any of the one or more requestors for files from the target system are routed directly to the target system without accessing a core network.Type: ApplicationFiled: August 30, 2011Publication date: February 28, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Seraphin B.
