device static routing, which is usually to specify one or more default gateways for end devices. The method of static routing simplifies the complexity of network management and reduces the communication overhead of terminal equipment, but it still has one disadvantage: if the router as the default gateway is damaged, all traffic using the gateway as the next hop host must be interrupted. Even if more than one default gateway is configured, you cannot switch to a new gateway without restarting
This week, we learned about the interpreter style. The interpreter is organized by reading and finding data.First, let's look at what an interpreter is:An interpreter is a programs that executes another program (the interpreter is a procedure used to execute other programs).An interpreter implements a Vsan, which may is different from the underlying hardware platform. (The interpreter implements a virtual machine for different hardware platforms.)To c

Virtual Routing Redundancy Protocol (Vsan Router Redundancy Protocol, abbreviated VRRP) can be used to avoid statically specifying the gateway's flaws.In the VRRP protocol, there are two important sets of concepts: the VRRP router and the virtual router, the master router, and the backup router. VRRP router refers to the router running VRRP, is a physical entity, the virtual router refers to the VRRP protocol created, is a logical concept. A group of

RMI IntroductionA remote method call (RMI) is the name of a program on a machine that calls a method on another machine. This gives you a general idea of what RMI is used for, but it's not quite clear. RMI is the cornerstone of a Java-supported distributed system, such as well-known EJB components. RMI is an object-oriented implementation of remote procedure call (RPC), which is implemented through socket communication and object serialization techniques. Here is a quote from Wikipedia about RMI

partially ensures the acid properties of the transaction.Physical architecture of the transaction logThe transaction log stores the changes that were made to the database, allowing SQL Server to recover the database. In this way we need to store the corresponding information, familiar to the people who are familiar with MSSQL, that is, when creating the database, the. ldf file created, let's look at its physical structure.In SQL Server, a log file is a virtual log file that divides logically an

First create an SDC file with the name consistent with the top layer of the project, and then add the timing constraint by following the steps below. 1. Create a clockthe first step in adding a timing constraint is to create a clock. To ensure the accuracy of the STA results, all clocks in the design must be defined and all relevant parameters of the clock specified. The t

Facebook's architecture analysis---reproduced in foreign languagesFrom various readings and conversations I had, my understanding of Facebook's current architecture are:
Web front-end written in PHP. Facebook ' s HipHop Compiler [1] then converts it to C + + and compiles it using g++, thus providing a high performance TEMPLA Ting and Web logic execution layer.
Because of the limitations of relying entirely on static compilation, Facebook's started to work on a HIPHOP interpreter [ 2] as we
Introduction to Mesos + DockerApache Mesos is a cluster manager this simplifies the complexity of running tasks on a shared pool of servers. Docker is a lightweight container for deploying packaged services, similar on concept to a vsan, but without th E overhead. Mesos added support for Docker in the 0.20.0 release and subsequently fixed some fairly large limitations in the following 0.20.1 patch release. The combination of Mesos + Docker provides a

The slave server, after receiving the database file data, will save it and load the memory.Thereafter, Master continues to pass all the modified commands that have been collected, and the new modification commands to Slaves,slave will execute these data modification commands at this time to achieve final data synchronization.Virtual Memory (Vsan)Redis's virtual memory is designed to guarantee the look

If packets are sent at the destination address, the network is called a packet network, and the IP protocol of the Internet is the sending of packets at the destination address, which is called a virtual line network if packets are sent according to the virtual line number.Packet networks are similar in many ways to postal services.
