Adaptive digital access protocol: a MAC protocol for multiservice broadband access networks

Using proxies to enhance TCP performance over hybrid fiber coaxial networks

“…Using cable modems operating at speeds ranging from hundred to thousand times the speed of conventional telephone modems, these services are expected to enable access from the home at broadband speeds [3].…”

An efficient scheme for accommodating synchronous traffic in a cable-modem network while avoiding segmentation of asynchronous packets

“…As a typical example, consider the cable-modem network described in [4]. The HE divides the time domain into a series of successive frames.…”

“…As in [4], the HE divides the time domain into a series of successive frames, and every frame is divided into synchronous and asynchronous regions (see Figure 2). Again, each region has multiple time slots, and the boundary between the two regions can be changed by the HE dynamically, according to the synchronous traffic load.…”

“…Cable-modem networks that support synchronous traffic on the upstream channel, like [2,4,8], require that the asynchronous packets will be broken down into a stream of fixed sized units (ATM or non-ATM cells) at the sending CM, and will be re-assembled at the HE after being delivered. As a typical example, consider the cable-modem network described in [4].…”

“…Several MAC protocols for the upstream channel have been proposed so far (e.g. [2,4,7,8]). The MXL protocol, presented in [7], is unique because it does 1 not require that the IP variable length packets will be broken down into a stream of fixed sized units (cells) at the sending CM and be re-assembled at the HE after delivery.…”
