Method and apparatus for monitoring and processing voice over internet protocol packets

A processor architecture for processing data packets representing voice over Internet Protocol (VoIP) calls in a packet-switched network is disclosed. According to an embodiment, a VoIP processor executes a voice packet processing operating system that is configured to monitor or manipulate the packets at an IP layer, media layer and signaling layer of the call. The VoIP processor includes a plurality of independently callable primitive software functions that carry out low-level VoIP packet processing functions. The VoIP processor executes one or more application programs that selectively call one or more of the primitive software functions and are independent of any underlying protocols of the existing network, thereby isolating the application programs from low-level processing details. Further, techniques are described for modifying characteristics of VoIP traffic for the purpose of monitoring and directing the VoIP traffic through a network. The techniques include extracting information associated with the VoIP traffic and using the information for the purpose of controlling access, for fraud detection, for billing, for enforcing policy decisions, for protection against denial of service attacks, for lawful interception, for service selection, and other applications.

ActiveUS20100011434A1Facilitate application level processingLow costError preventionFrequency-division multiplex detailsTraffic capacityHash function
An apparatus is described that associates categorization information with network traffic to facilitate application level processing through processing of network traffic in accordance with provisioned rules and policies. The apparatus includes a plurality of microcode controlled state machines, wherein at least one microcode state machine processes at least one input data field using a hash function to generate a hash identifier. This embodiment further includes a distribution circuit that routes input data to the plurality of microcode controlled state machines, such that at least one individual microcode controlled state machine applies a rule to the input data to produce the at least one input data field, and to produce modification instructions based on the hash identifier. This embodiment further includes a first circuit that appends the hash identifier to the input data to produce modified input data based on the modification instructions, and that routes the modified input data in accordance with an output routing strategy. Advantageously, the apparatus provides an architectural framework well suited to a low cost, high speed, robust implementation of flexible, advanced network security and monitoring features and network traffic analysis.

Flue gas-treating method and apparatus for treating acidic tail gas by using ammonia process

ActiveUS9370745B2Improve desulfurization efficiencyEffectively control the ammonia slip and the aerosol generationGas treatmentDispersed particle separationFlue gasAmmonia storage
A flue gas-treating method for treating acid tail gas by using an ammonia process, comprising the following steps of: 1) controlling the concentration of sulfur dioxide in an acid tail gas entering an absorber to be ≦30,000 mg / Nm3; 2) spraying and cooling with a process water or / and an ammonium sulfate solution in the inlet duct of the absorber or inside the absorber; 3) providing an oxidation section in the absorber, wherein the oxidation section is provided with oxidation distributors for oxidizing the desulfurization absorption solution; 4) providing an absorption section in the absorber wherein the absorption section achieves desulfurization spray absorption by using absorption solution distributors via an absorption solution containing ammonia; the absorption solution containing ammonia is supplied by an ammonia storage tank; 5) providing a water washing layer above the absorption section in the absorber, wherein the water washing layer washes the absorption solution in the tail gas to reduce the slip of the absorption solution; 6) providing a demister above the water washing layer inside the absorber to control the concentration of mist droplets contained in the cleaned tail gas. In the coal chemical industry, the integration of the Claus sulfur recovery process and the ammonia desulfurization technology can reduce the investment of the post-treatment and simplify the operation process, and provide intensive advantages to the environmental control of plants.
