AI Technical Summary

Problems solved by technology

As a result, the throughput of a communications switch is limited or constrained by the CPU capabilities inside the switch and the other processing functions the CPU must also provide
This processing constraint leads to congestion and quality of service ("QoS") problems in the switch

Embodiment Construction

[0019] While the making and using of various embodiments of the invention are discussed in detail below, it should be appreciated that the invention provides many applicable inventive principles that can be embodied in a wide variety of specific contexts. For example, besides telecommunications systems, the invention may also be applied to other forms of communication or data processing in general. Other forms of communication may include communication between networks, communication via satellite, or other forms of communication not known as of the date of this invention. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0020] The present invention provides a method and a device for creating packets including the necessary headers in a digital signal processor instead of in a CPU implementing a protocol stack. As a result, the present invention relieves a significa...

Abstract

The present invention provides a method and apparatus for creating a packet using a digital signal processor. Call set-up information is received (624). Thereafter, call data is received (628) and a data portion of the packet is created (630) using the call data. One or more headers are created (632) using the call data and the call set-up information. The packet is then created (632) by attaching the one or more headers to the data portion of the packet. In addition, the one or more headers may include a real time transport protocol header, a user datagram protocol header, an Internet protocol header, and a media access control header.

Description

technical field [0001] The present invention relates generally to the field of communications, and more particularly to a method and apparatus for creating packets using a digital signal processor. Background technique [0002] The ever-increasing demand for data communications has prompted the development of technologies that provide more cost-effective and efficient ways of using communications networks to handle greater amounts of information and new types of information. One such technique is used to segment information, possibly voice or data communications, into packets. A packet is typically a set of binary numbers including at least data and control information. Integrated packet networks (typically, fast packet networks) are typically used to carry at least two types of traffic, which may include, for example, continuous bit rate ("CBR"), voice ("packet voice"), data ("frame formatted data") ), images, and so on. Packets network source, sink and / or forward protoc...
