The dramatic growth in the volume of traffic over cable modems has increased the demand for traffic modeling and planning mechanisms for verifying cable network performance via traffic generators and analysis platforms. Packet generators of today offer highly sophisticated utilities to generate custom traffic mixes for Layer 2 and Layer 3 devices in an effort to simulate real-world Internet traffic patterns. In addition, such analysis systems assist cable network engineers in developing and deploying cable systems in the networks by measuring their performance and gathering metrics such as throughput, packet loss, and latency.
