Between February 2011 and February 2012, 985 and 324 samples were collected from diarrheal and healthy pigs, respectively, to detect porcine epidemic diarrhea virus (PEDV), porcine kobuvirus (PKoV), porcine bocavirus (PBoV), porcine group A rotavirus (GARV), and transmissible gastroenteritis virus (TGEV). PEDV and PKoV clearly predominated in diarrheal(More)
With the widespread penetration of broadband accesses, many multimedia applications, such as video surveillance, on-demand video streaming, IPTV and news broadcast are emerging. Since video streaming applications on the Internet generally have very high bandwidth requirements and yet are often unresponsive to network congestion. In order to avoid congestion(More)
In this paper, we present a receiver-based, bandwidth estimation rate control mechanism with content-aware probability retransmission to limit the burden on multimedia transmission congested network. Like the TCP friendly rate control (TFRC) protocol, we compute the sending rate as a function of the loss event rate and round-trip time. Considering the(More)
With the security industry developing rapidly and the number of security systems increasing continuously in recent years, security systems provide a positive effect on society security in China, but many of them became vulnerable or even useless because of the problem of irrational allocation of resources. In order to evaluate security system efficiency to(More)
The success of peer-to-peer overlay multicast for media streaming depends on their scalability. However, as multicast functionality is pushed to autonomous, unpredictable end systems, significant performance loss can be resulted from their higher degree of churn when compared to routers. Data distribution path over an overlay consisting of unreliable peers(More)
In this paper we introduce Faster-Restart, an optional mechanism for safely improving sender's transmission rate during the restart in a multicast communication. The key challenge in the design of the mechanism lies in utilizing network information before and after idle periods, reasonably controlling rate increment and therefore reaching the balance(More)
