A Preliminary Study on Huawei and Cisco IPv6. The Global IP address of link-local address in IPV6 is not enough, and IPV6 is gradually launched. You don't need to talk about the benefits of IPv6, such as supporting IP Security, for example, not

You must know the Special IP addresses in the IP address. You must know one type of IP addresses. These IP addresses cannot be used in public network 1, local address 127.0.0.X send-back interface 2, Class A address 10. x. x. class A address for X 3,

Network Protocol designers should not design a single, huge protocol to provide complete details for all forms of communication, but should divide communication problems into multiple small problems, then a separate protocol is designed for each

TCP-UDP Transport Layer ProtocolTCP and UDP are the transport layer protocols of the TCP/IP protocol family: 1. TCP: connection-oriented: the process of creating a connection, communication between the two parties, and closing the connection. The

Introduction to TCP/IP architecture the TCP/IP protocol set divides the entire network into four layers, including the network interface layer, Internet layer, transport layer and application layer. 1. network Interfaces and Communication Subnet

Expression: the basic expression of an IPv6 address is X: X. Each number contains 4 hexadecimal data and the tool is 128 bits. The starting 0 does not need to be expressed. The above is the most basic expression method, and there are two more clear

Cisco ACL has two types: Standard ACL and extended ACL. The standard ACL of www.2cto.com allows or rejects traffic based on the source IP address. The destination address and port contained in the data package are irrelevant. The example on the

What are the functions of the ping command? The ping Command www.2cto.com is used to check the smoothness of the network. ping is an ip testing software that comes with window. It can test whether the local machine is connected to a vro. For example,

Currently, for communication analysis of applications on mobile devices, HTTP layer data packets can be captured and changed using web Proxy tools, the underlying data packets must be analyzed in real time and visually (non-real-time tcpdump can be

The Extension Header of IPv6 is an optional Header that may follow the basic IPv6 Header. An IPv6 packet can contain one or more extension headers. Of course, there can be no extension headers. These extension headers can have different lengths. The

Many people like to complain about the lack of real-machine labs and the poor support of simulators. I don't think so. The potential of the simulator is infinite. Wait for you to explore it. The original topology of www.2cto.com described the

TCP details: TCP Data Interaction 2: TCP data interaction as mentioned earlier, TCP is a reliable protocol, because there is a data arrival confirmation mechanism between the sender and the receiver, if the sender does not receive a confirmation

Which layers does the OSI/RM model contain and the main functions of each layer the OSI/RM model contains seven layers: the Application Layer directly provides the service transport layer for your applications to provide services for communications

TCP/IP quickly understands that TCP/IP is a communication protocol for the Internet. Computer Communication Protocols are descriptions of the rules that computers must comply with in order to communicate with each other. What is TCP/IP? TCP/IP is a

The connection and difference between SNMP V1 and V3. SNMP is a protocol used to manage nodes on the network (including workstations, routers, switches, hubs, and other peripheral devices ). SNMP is an application protocol that uses UDP

Vpn Principle and Implementation-generally, openvpn implements Security Based on openssl, but it is not an sslvpn in the traditional sense. It is just a common vpn that works on the ip layer rather than the transport layer. Vpn has two meanings: v,

Cisco dual-ISP line access, link automatic switch solution recently received a project, the customer headquarters in Huizhou, the branch in Hong Kong, the Hong Kong Branch has an ERP server and mail server, the Headquarters egress is the leased line

TCP connection establishment process and TCP connection termination process 1. TCP connection establishment process-"three handshakes" (1) when the client wants to communicate with the server over TCP, the system first sends a SYN synchronization
