International Classification:

G06F 15/173

US Classification:

709224, 709219, 709225

Abstract:

A method is disclosed for determining attributes of a client connection configured for use with a telecommunications network; comparing determined attributes with location definition information stored in a configuration file; determining at least one user-defined location in the location definition information associated with the client connection based on the comparison; wherein the method is performed by one or more computing devices.

US Classification:

370254000

Abstract:

A method is disclosed for determining a location of a client session in a telecommunications network by comparing attributes of the client session connection to location definition information stored in a configuration file. A method of handling requests from proxy and non-proxy client connections in a telecommunications network by redirecting requests from unauthenticated proxy clients to a transparent proxy port on a captive portal such that the captive portal proxies the requests is also disclosed. The request may be directed to a service, such as a destination IP address and optional port number. A method for a proxy server to identify an edge session through an out-of-band request containing proxy metadata to a web portal for secure (HTTPS) requests is also disclosed. The edge session is identified for the web portal through a hostkey determined by the proxy server.

International Classification:

G06F 15/16

US Classification:

709227000

Abstract:

A method is disclosed for determining whether access to a host requested by a client session connection is permitted. After determining attributes of the client session connection, a list of hosts is selected based on the determined attributes of the client session connection. The list of hosts is then used to determine whether access to the requested host is permitted. The disclosed method can be used to allow for location-specific white lists of free URLs for a user at a wireless network hotspot that the user can access before being authenticated.

US Classification:

Abstract:

Embodiments of the present invention relate to detecting and rectifying corruption in a distributed clock in a distributed system. Aspects may include receiving a sequence number used as part of the distributed clock at a node and determining if the sequence number is corrupt. In order to provide an effective mechanism for determining a sequence number is corrupt and taking corrective actions, a valid sequence number range may be determined, a propagation count associated with the sequence number may be evaluated, an estimated sequence number may be calculated, and an epoch number associated with the sequence number may be evaluated. Additionally, in exemplary aspects node with a corrupt trusted sequence values may self diagnosis and terminate associated processes to prevent further propagation of the corrupt sequence number.
