the replication scheme. Replication schemes May is created that does not include the current host. If the host has multiple network interfaces, the route can be used to specify the interface for replication. Specify by IP addressSet up different network ports, one for load balancing, and two for error switching.The following is an example of error switching, which can be used as the priority 2 interface of a backup when a pair of interfaces to the 1 fails:CREATE ACTIVE STANDBY PAIR dns1, d

site users upload pictures, attachments, avatars, etc., note that the site's program code should not be placed in the NFS share, because the website program is the development of operation and maintenance personnel unified release, there is no release delay issue , direct bulk Publishing to Web nodes provides access more efficiently than sharing to NFS. NFS is one of the most commonly used data storage services in the current Internet system architecture, and small and medium-sized websites can

This chapter goes through the previous chapter and briefly describes what the four components are responsible for in the entire transport architecture of Exchange Server 2013.Front End Transport services (the Front End Transport service)The FET service seems to be minimal in the entire transmission, it is responsible for inbound and outbound SMTP traffic for all

TCP/IP is a commonly used standard protocol for network interconnection. It can communicate with each other in different environments and nodes, it is the protocol used by all computers connected to the Internet to exchange and transmit various information over the network. It is also the protocol used for interconnection between Windows NT, Windows 2000 Server, NetWare and UNIX. TCP/IP is actually a hierarchical protocol. It contains many other protocols and forms a TCP/IP protocol group. The P

How can we correctly transport hard drives? From data centers to archive storage, hard drive has experienced an adventure. The right way to transport hard drives to ensure their security. An executive layer of a hard drive company once told me that he saw a luggage handler outside the window treating his suitcase rudely at San Lois airport. After careful observation, he realized that the hard disks were fo

When using ecshop Ajax (that is, transport. JS) IE sometimes appears:Referenceerror: process_request is not defined, FF appears:Transport.

Computer network transport layer I. Introduction as mentioned earlier, transport layer is responsible for providing services for communication between processes in two hosts. It is the highest level for communication and the lowest layer for user functions. The transport layer provides multiplexing and demultiplexing functions, as well as packet error detection.

As long as the data information to the Baidu Map server, We are ready to pr

TCP and UDP are protocols in the transport layer in the OSI model.TCP definitionTCP (transmission Control Protocol Transmission Protocol ) is a connection-oriented, reliable, byte-stream-based Transport Layer communication protocol defined by the IETF RFC 793.
