", describes some complex topics such as load balancing and minimizing convergence time. In this chapter, the term bridge, switch, and tier two switches are used interchangeably. While some argue that these terms vary widely between different types of devices, these differences are not affected when we discuss spanning trees, especially when discussing STP standards that have been completed prior to the development of hardware switches. For example, you will learn the concept of "Root Bridge" (w

I. Mac sublayer Basics1. the MAC Sub-layer has two main functions: addressing (MAC address), that is, addressing the target node; second, it is used to prevent multiple users from competing to share physical media or channels.2. Two Channel types: point-to-point channel, which requires no intermediate device between two nodes and encapsulates point-to-point data link layer protocol; and broadcast channel, it is a situation where a channel is shared by multiple links (shared channels and physical

Deep understanding of Java Virtual Machine-Chapter 6 Java Memory Model and thread, and Chapter 4 Chapter 2 Java Memory Model and thread Java Memory Model Master memory and working memory: The java Memory Model specifies that all variables are in the main memory, and each thread has its own working memory. The worker memory stores copies of the master memory used by the thread. All operations on variables b

ideas out of, many times I think, according to their own logic to push, Not to prove that you are right, but to prove that you are thinking. Such moments of thinking are not given to other disciplines.There are many times, or so, should be to listen to other people's advice, rather than immediately to prove that they are right, think is rational things, it should be in meditation after the results, we actually want to think about the final process, and not just for one's own grievance or other

Understanding the basic thread mechanism of java-18.2 from the ground up (6)-using constructors or internal classes to implement multi-thread coding variations In this section, we will discuss how to use constructors or internal classes to implement multi-threaded coding variations. 1. Basic implementation package com.ray.ch17;public class Test {public static void main(String[] args) {Thread thread1 = new E

Eden District.VI. Allocation of space guaranteesBefore the minor GC occurs, the virtual opportunity first checks whether the largest contiguous space in the old age is greater than the sum of all object sizes in the Cenozoic. If this is true, the minor GC is safe. Otherwise, the virtual machine needs to look at the value of the handlepromotionfailure to see if the guarantee fails to run, and if so, the virtual machine continues to check that the largest available contiguous space in the old age

the Setcontextclassloader method of the thread context.Java EE is only a specification, sun company only gives the interface specification, the specific implementation by each vendor implementation, so JNDI,JDBC,JAXB and so on these third party's implementation library can be called by the JDK class library. The thread context ClassLoader also does not follow the parental delegation model.(3). In recent years, Hot code replacement, module thermal deployment and other applications require the co
