TL;DR: Results are presented which indicate that I-SWIFT performs significantly better than previous compatible voice/data integration methods.
Abstract: A novel method (referred to as I-SWIFT) is presented for integrating the flow of synchronous voice streams into existing broadband cable systems using CATV (community antenna television) technology. The interface between the integrated voice subnetwork and the cable system is realized by a metropolitan area gateway (MAG) which is implemented at the broadband cable head-end. An intelligent scheduling algorithm in the MAG dynamically allocates channel bandwidth using a variation of the data-switch-filtering techniques first introduced by T. D. Todd (1987). The MAG accomplishes this by establishing a fixed voice frame (with realignment) which is implemented in an upwardly compatible fashion with respect to the existing CSMA/CD (carrier-sense multiple access with collision detection) data stations. Thus, previously installed stations require no modification. Results are presented which indicate that I-SWIFT performs significantly better than previous compatible voice/data integration methods. >

TL;DR: It is shown that for typical system design parameters, the I-SWIFT gateway approach can achieve much improved performance over previous compatible voice/data integration methods.

The interface between the integrated voice subnetwork and the cable system is realized by a metropolitan area gateway (MAG) implemented at the broadband cable headend. In I-SWIFT, an intelligent scheduling algorithm in the MAG dynamically allocates channel bandwidth using modified data switch-filtering techniques. The MAG accomplishes this by establishing a fixed voice frame (with realignment) which is implemented in an upwardly compatible fashion with respect to the existing carrier-sense multiaccess communication with collision detection (CSMA/CD) data stations.

TL;DR: A novel gateway design is presented for integrating the flow of voice streams into existing broadband cable systems and results indicate that the T-SWIFT design performs significantly better than previous compatible voice/data integration methods.
Abstract: A novel gateway design (referred to as T-SWIFT) is presented for integrating the flow of voice streams into existing broadband cable systems. The interface between the integrated voice subnetwork and the cable system is realized by a metropolitan area gateway (MAG) which is implemented at the broadband cable head-end. In T-SWIFT, an intelligent scheduling algorithm in the MAG dynamically allocates channel bandwidth using a variation of the data switch-filtering and fixed-frame synchronous voice/data integration techniques introduced by the author (see IEEE J. Selected Areas in Commun. vol., SAC-5, no.9, p.1391-1402 (1987)). The MAG accomplishes this by coordinating the transmission of inbound and outbound voice talkspurts in an upwardly compatible fashion with respect to the existing CSMA/CD data stations. Thus previously installed stations require no modification. Results are presented which indicate that the T-SWIFT design performs significantly better than previous compatible voice/data integration methods. >
