CATV networks were originally designed to deliver analog broadcast TV services to subscriber TV sets, thus adopting a standard tree-and-branch topology and allocating most of the transmission channel bandwidth for downstream analog channels Typically, CATV networks are built as hybrid fiber-coax (HFC) structures with fiber spanning between a video head-end or a hub to a curb optical node, with the final drop section deployed using standard coaxial cable technology and repeaters (amplifiers) and tap couplers to split the signal among many subscribers Faced with the growing competition from telecom operators in providing Internet services, cable television companies responded by integrating data services over their HFC cable networks, which, in turn, required replacing single direction (downstream) signal amplifiers with bidirectional amplifiers, in order to enable the upstream data path An updated medium access protocol was also required to allow access of multiple subscribers to the same shared transmission channel, while avoiding collisions between individual data transmissions However, since most of the usable transmission spectrum is tieddown with TV signal delivery, both downstream and upstream channels in such systems are very limited in bandwidth, thus providing decent access rates for only a limited number of subscribers It is interesting to note that, while the highly asymmetric nature of the traffic is observed in DSL and CATV systems, new and emerging applications tend to drive the bandwidth ratio toward unity Applications such as video conferencing or data storage using storage area networks (SANs) require a symmetric transmission channel File-sharing applications, as well as peer-to-peer traffic such as eDonkey, Kazaa, and Napster (to name just a few of them), increase traffic symmetry since each connected user simultaneously operates as network client and server, thus receiving and transmitting on average the same amount of data It was recently reported that the current ratio of downstream to upstream traffic is approximately 14 to 1 [4] The recent advent of IPVideo services and video file hosting services ie YouTube seems to skew this ratio again towards strong asymmetry (YouTube video sessions account for 20% of overall HTTP transactions and 10% of the overall traffic observed on the networks) [5] As a result of streaming audio and video in Web downloads, HTTP traffic constitutes approximately 46% of all data transmitted over Internet, while the ratio itself has a strong positive increase factor For comparison, symmetric P2P traffic constitutes in total roughly 37% of data being transmitted For some time, it has been expected that the traffic ratio would reach the full symmetry condition (1 to 1), with downstream and upstream data flows more or less balanced The recent evolution of VoD applications, however, seems to bring the ratio into asymmetry again, with the downstream flow strongly dominating the upstream traffic (see: http:// grouperieeeorg/groups/802/3/cfi/0306_1/cfi_0306_1pdf) Data traffic is increasing at an unprecedented rate, with a sustainable traffic growth rate of over 100 percent per year observed since 1990 (already quoted: wwwieee802org/3/hssg/public/mar07/bach_01_0307 pdf, wwwieee802org/3/hssg/public/jan07/lee_01_0107pdf, or wwwieee802org/3/hssg/ public/sep06/steenman_01_0906pdf) There were periods when a combination of economic and technological factors resulted in even greater growth rates, eg, a 1000 percent increase per year in 1995 and 1996 [6] This trend is likely to continue in the future, especially with the deployment of Voice over IP (VoIP) telephony and with the increasing.

scanf( )

We haven t yet created any data storage for our wiki pages, but if we drop a RichTextBox below the splitter on the right, we can hook up some of the application commands right away. Because they ll do something, we re going to hook up the cut, copy, and paste commands right now.

The general-purpose console input routine is scanf( ) It reads all the built-in data types and automatically converts numbers into the proper internal format It is much like the reverse of printf( ) The prototype for scanf( ) is int scanf(const char *fmt_string, ); The fmt_string determines how values are read into the variables pointed to in the argument list The format string consists of three classifications of characters: I Format specifiers

Passive Optical Networks (PONs)

I White-space characters I Non-white-space characters The scanf( ) function returns the number of fields that are input It returns EOF if a premature end of file is reached

The menu items are already created, but they don t do anything yet. If you re following along, open your WikiWindow.xaml, and we ll add this functionality remarkably quickly with the following steps:

The input format specifiers are preceded by a % sign and tell scanf( ) what type of data is to be read next These codes are listed in Table 8-3 The format specifiers are matched, in order from left to right, with the arguments in the argument list
