Optical Crossover Connector (OXC) and optical divider (OADM) are used to complete the switching function ). After several years of research and experiments, all-optical networks are now developing in an intelligent direction. Automatic Switching Optical Networks (ASON) is the mainstream direction for intelligent development.
Strictly speaking, wave splitting switching is different from wavelength routing. Wavelength converter is required for wavelength division switching networks, while wavelen
connection persistence time is relatively short, it will cause the channel utilization to deteriorate. Therefore, it is not suitable for continuously increasing and changing Internet traffic, such as web browsing, FTP file transmission, and email.In optical switching, OPS provides better bandwidth utilization, latency, and adaptability. In the long run, OPS seems to be a promising technology, but its implementation is complicated and the current optical logic processing technology is not mature
Understanding the observer mode of java Design PatternsIn actual life, we often encounter changes in data of things, such as the temperature recorder in life. When the temperature changes, we observe the curve of the temperature change, temperature logs. For this type of problem, it is very close to the "Observer mode" in the java design mode. It is suitable for the program structure problem where multiple objects track the changes of an object's data

Today, when reading Professor Wu Xizhi's "Complex data statistics method", encountered a data set according to a certain factor into subsets, and then a few subsets randomly divided into n parts of the problem, Professor Wu's method is better understood, but I still feel a bit cumbersome, so I wrote a function, After that, you just need to run the function.This uses the iris dataset that comes with R,> str (IRIS) ' data.frame ': Obs. of 5 variables:$

A recorder is an object that developers often interact. The main APIs describe what we want to record.
For example, a recorder can categorize requests to send a message without worrying about how they are sent.
For example, when we writelogger.info(“St

After several years of research and experiment, all optical networks are developing in the direction of Intellectualization, and automatic switched Optical Network (ASON) is the main direction of intelligent development.
In strict terms, wavelength-sharing is not the same as the wave-length routing. WDM networks must have wavelength conver
Hot vs Cold observables
Understanding the nature of hot and cold observables are a crucial part to master observables. Before we try to explore the topic through some practical examples, let's read through the definition from the RxJS projec T itself
Cold observables start running upon subscription, i.e., the observable sequence only starts pushing values to the Observer s when the Subscribe is called. (...) This was different from hot observables such as mouse move events or the stock tickers

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprecedented rate. Currently, DWDM technology is used in the optical layer. The available bandw
