20090219813 | Application specific service ping packet - A method of using an application specific service ping packet, and related application specific service ping packet, including one or more of the following: creating the application specific service ping packing including a special packet identification field that identifies the application specific service ping packet as a special packet, and including an application identification field that identifies an application to which the application specific service ping packet corresponds; modifying a deep packet inspection engine to recognize the application specific service ping packet; sending the application specific service ping packet through a deep packet inspection element; identifying the application specific service ping packet as a special packet; determining that the application specific service ping packet can be mapped to a specific application; identifying the specific application; setting an application for processing to the specific application; and performing known application processing based on the set specific application. | 09-03-2009 |
20090238192 | In-band DPI application awareness propagation enhancements - Various exemplary embodiments are a method and related device and computer-readable medium including one or more of the following: receiving a packet sent from the source node to the destination node; associating the packet with an active flow by accessing information in the packet; performing deep packet inspection (DPI) to identify an application associated with the active flow; associating application-identifying information with the packet; forwarding the packet including the application-identifying information towards the destination node; and performing application-specific processing at a downstream device on at least one packet belonging to the active flow, the downstream device identifying the application associated with the active flow by extracting the application-identifying information from the packet. | 09-24-2009 |
20100054204 | SYSTEM AND METHOD OF SERVING GATEWAY HAVING MOBILE PACKET PROTOCOL APPLICATION-AWARE PACKET MANAGEMENT - Mobile protocol packets, with a header field and a payload field, are communicated from a user mobile equipment to an application-aware serving gateway. The application-aware mobile protocol serving gateway detects header information in the header field and application information in the payload field to manage the mobile protocol packets based on a policy. | 03-04-2010 |
20100054231 | DPI-TRIGGERED APPLICATION-AWARE DORMANCY TIMER ADJUSTMENT FOR MOBILE DATA BEARERS - Based on application information received from a Deep Packet Inspection (DPI) device, a Radio Network Controller (RNC) or similar device may select a dormancy timer value to optimize the use of network resources. In particular, the RNC may set an additional dormancy timer based on a default value or a rough determination of the application by examining port numbers. After the DPI device has received a sufficient number of packets to identify the underlying application, the DPI device may then propagate the application information to the RNC. Based on this application information, the RNC may determine the most efficient dormancy timer and modify the value of the default timer based on this determination. | 03-04-2010 |
20100054257 | IN-BAND DPI MEDIA RESERVATION MODIFICATIONS TO RFC 3313 - In various exemplary embodiments, a Deep Packet Inspection device is integrated into a provider edge router associated with a user agent client or provided externally. The DPI device monitors the exchange of packets between an originating proxy and a user agent client and inspects the packets to identify SIP control messages. By monitoring the messages exchanged between the two devices, the DPI device may determine the type of application, desired QoS, source, destination, and other information related to the connection. Using this information, the router may then access a policy database to determine whether there is a QoS policy for the application and/or user. Based on this determination, the router may initiate network reservation for an anticipated data flow or store the information so the flow of packets can be remarked as the packets arrive. Accordingly, in various exemplary embodiments, the edge router is aware that QoS should be granted. | 03-04-2010 |
20100057940 | APPLICATION-AWARE M:N HOT REDUNDANCY FOR DPI-BASED APPLICATION ENGINES - A packet processing system for providing application-aware hot redundancy and a related card and methods are disclosed. The system may include a plurality of active devices, each including a processor configured to perform deep packet inspection to identify an application associated with an active flow, and a redundancy block configured to determine whether the application requires hot redundancy and, if so, to forward a message from which state information may be derived. The system may also include at least one protecting device in communication with each of the active devices and configured to receive the message regarding the active flow from the active device, derive state information from the message, and resume packet forwarding operations for the active flow upon failure of a respective active device of the plurality of active devices. | 03-04-2010 |
20100067400 | APPLICATION-LEVEL PROCESSING FOR DEFAULT LTE BEARER IN S-GW - A serving gateway facing a radio access network receives packets, applies deep packet inspect to classify the packet into a predetermined application class, and inserts a marker identifying the class and a QoS associated with the class. The serving gateway assigns the packets to a queue within a default bearer based on the class and the QoS marker. The serving gateway transfers packets through the bearer by processing the queues in accordance with their priority. | 03-18-2010 |
20130142123 | System and Method of Serving Gateway Having Mobile Packet Protocol Application-Aware Packet Management - Mobile protocol packets, with a header field and a payload field, are communicated from a user mobile equipment to an application-aware serving gateway. The application-aware mobile protocol serving gateway detects header information in the header field and application information in the payload field to manage the mobile protocol packets based on a policy. | 06-06-2013 |
