Abstract
We consider a home networking system for integrating packetized isochronous and best-effort traffic over a shared link with limited bandwidth, wherein the isochronous traffic comprises multiple isochronous flows, each associated with a periodic packet arrival process having a constant isochronous packet transmission period. In such a system, best-effort packets of variable size can render it impossible to guarantee QoS of the isochronous traffic. We propose a dynamic packet fragmentation fragmentation method to integrate isochronous and best-effort traffic, in particular, fragmentation with fixed size or variable size frames. We show that the method effectively increases link utilization and best-effort traffic throughput, without violating the delay and jitter requirements for isochronous traffic.
