Internet packet loss and delay exhibits temporal dependency. If packet n is lost, packet n + 1 is also likely to be lost. It leads to bursty network losses and late losses in real-time multimedia services such as Voice over IP (VoIP). This may degrade perceptual quality and the effectiveness of Forward Error Correction (FEC). To characterize this burstiness, we rst discuss the modeling of packe...
This paper addresses the problems involved in performing speech recognition over mobile and IP networks. The main problem is speech data loss caused by packet loss in the network. We present two missing-feature-based approaches that recover lost regions of speech data. These approaches are based on reconstruction of missing frames or on marginal distributions. For comparison, we also use a tack...
This paper proposes a novel traffic engineering method for improving the throughput characteristics of optical packet forwarding in an optical packet / path integrated network. This method is based on bypassing optical packets rejected from a highly-loaded optical packet switch onto one of the adjacent packet switches via an optical path to increase the network throughput. Since the formation o...
Abstmct-We investigate packet loss in mobile ad hoc networks via simulation. Ad-hoc on-demand distance vector (AODV) and destination-sequenced distance vector (DSDV) are chosen as representatives of the on-demand and proactive routing protocols respectively. The effects of congestion and mobility in various network contexts are explored. The results indicate that DSDV loses 10% to 20% more pack...
The advent of Network Function Virtualization (NFV) and Service Chains (SFCs) unleashes the power dynamic creation network services using Virtual Functions (VNFs). This is great interest to operators since poor service quality resource wastage can potentially hurt their revenue in long term. However, study shows with a set test-bed experiments that packet loss at certain positions (i.e., differ...
