What are the requirements for a task that creates JARs? A good place to start is to the command-line tool, jar. At a minimum, our task should replicate the JAR-creating features of the tool (as opposed to all of the tool's features). This distinction is important. We're not reimplementing the jar tool, we're creating an operation for our build, sat...

The apply, exec, and java tasks accept nested <arg> elements, specifying command-line arguments for their respective process calls. The org.apache.tools.ant.types.Commandline.Argument class implements this DataType.1 If several <arg> elements are specified, each is treated as a separate argument to the process call. Following is a list ...

With XML elements and tags, we can look at the primary components of an Ant buildfile as components or building blocks. We build the buildfile using these blocks. Some pieces have very specialized uses, while others are more common and used more frequently. Let's look at the primary components of the Ant buildfile. .1 The Project We call the set of...

Implementations of complex modulations may have constellations with as many as 256 or 512 signal points. They correspond to operating at 8 bits/baud and 16 bits/baud. Great care is taken to arrange the signal points so that they are equidistant from one another. This is necessary to provide an equal area around each point in which errored signals m...

In the local loop, carriers have installed fiber to carry multiplexed signal streams close to their destination. They terminate in optical network interfaces (ONIs) where twisted pairs are used to complete the connection to residences or small businesses. Several acronyms are used to identify such installations: ã FITL: fiber in the loop; ã FTTC: f...

Electric currents, electromagnetic waves, and optical energy carry messages on transmission facilities. The availability of ubiquitous transport is a prerequisite for the operation of the networks described in earlier chapters. It is tempting for managers to fantasize about owning all the communication facilities needed to support an enterprise. Ho...

Router Figure 5.9 is a functional diagram of a router. A database of routes is stored and maintained by all routers. Called a routing table, it contains information concerning routes between the node owning the table and the potential destination nodes. At a minimum it includes the destination ID, intermediate interface ID(s) and forwarding address...

Routing How frames are routed over a packet-switched network depends on the instructions given by the users. Three basic styles, similar to the routing techniques employed in router driven networks, can be distinguished: ã Distributed routing: On the basis of information about traffic conditions and equipment status (network map, port status), each...
