When we die, we leave imprints of our online lives behind. What should be the fate of these digital footprints after our death? Using a crowdsourced online survey with 400 participants from four countries, we investigate how users want their digital footprint handled after their death, how they would like to communicate these preferences, and whom they would entrust with carrying out this part ...

To implement the ATM architecture over IP networks, MPLS was introduced. MPLS is a recent network technology that transmits traffic effectively and supports QoS on the Internet [1]. Some researcher worked on MPEG-4 and video streaming over the MPLS networks [1] and [8] respectively. [1] proposed a new architecture based on CR-LDP for MPEG-4 video streaming. It also concludes that it is necessar...

One of the main barriers to the commercial success of Voice-over-IP (VoIP) services beyond a single domain (e.g., a company intranet, a single operator’s domain) as a viable alternative to the classical voice telephony services is Quality-of-Service (QoS). The ability to deliver QoS is particularly challenging in next-generation networks, where VoIP services will be accessible via a variety of ...

effects of different planting on phenology, grain yield and its components of two sunflower culitvars were investigated. in 1996, an experiment was conducted in the experimental field of azad islamic university of khorasgan, located in khatonabad village, isfahan. the experiment was arranged in a randomized complete block design with a split plot layaout and four replications. the main plots co...

We consider an integrated-services communication network handling, in particular, best-effort data traffic and rate-regulated, delaysensitive variable bit-rate (VBR) traffic. From the user’s perspective, the pricing mechanism of the network may provide an incentive for the user to transmit best-effort packets in the real-time VBR channel, i.e., transmit best-effort packets “in-band” using some ...

The convergence of wireless systems with brooadband services is the challenge of future generations’ wireless networks. In recent years, several designs for enhancement of second-generation media access control(MAC) protocols have been proposed. They mainly focus, however, on digital voice/data scenario and are partially interested in the problem of transporting other realtime broadband traffic...

Video prefetching is a technique that has been proposed for the transmission of variable-bit-rate (VBR) videos over packet-switched networks. The objective of these protocols is to prefetch future frames at the customers’ set-top box (STB) during light load periods. Experimental results have shown that video prefetching is very effective and it achieves much higher network utilization (and pote...

In ATM networks congestion control plays an essential role to support diierent quality of service guarantees for a large variety of traac types. While for real-time communications, such as CBR and VBR services, a preventive open-loop congestion control mechanism is applied, a reactive closed-loop mechanism has been suggested for the ABR service class, which was introduced aiming at data communi...

In this paper efficient modeling of VBR MPEG coded video sources is proposed by appropriately combining properties of frame and GOP layer signals. In particular, a Markov chain is presented for modeling the video activity, the states of which correspond to correlated AR models responsible for generating the I, P and B frames. Furthermore, an adaptive implementation of the AR coefficients is acc...

VBR compressed video is known to exhibit significant, multiple-time-scale rate variability. A number of researchers have considered transmitting stored video from a server to a client using smoothing algorithms to reduce this rate variability. These algorithms exploit client buffering capabilities and determine a “smooth” rate transmission schedule, while ensuring that a client buffer neither o...
