1.Case Demand Analysis
This case uses the RHEL5 and Windows XP system environment to establish a secure ssl vpn connection 8.2 for two remote LAN and remote network management workstations across insecure Internet networks ).
The gateway servers of Beijing headquarters and Shanghai Branch both use the RHEL5 system. OpenVPN must be configured separately to connect two remote LAN LAN1 and lan2. In addition, the netw
Network, relationship and other data into the adjacency matrix (red represents two nodes is a person, there is a link between), but the resulting matrix will be due to the order of the problem of the different arrangement, in the first will find that because there is a clustered block area and easily divide the data into two parts, Then according to the specific meaning of the data to know the meaning of its representative, in this figure can be seen

Network programming can be divided into TCP-based network programming and UDP-based network programming. TCP is a connection-oriented byte stream and is often used for reliable network transmission. UDP is a datagram-
A layer-3 network is a layered layer-3 network. The three-tier network architecture adopts a hierarchical model design, which divides the complex network design into several layers. Each layer focuses on some specific functions, in this way, a complex big problem can become many simple small problems. The three-tier
Due to the limited network protocols supported by wireless devices, they are limited to HTTP, Socket, UDP, and other protocols. Different manufacturers may also support other network protocols. However, MIDP 1.0 specifications stipulate that, HTTP is a required protocol, while other protocols are optional. Therefore, in order to port on different types of mobile phones, we try to use HTTP as the preferred p

IP address
The IP address is a network-layer communication address expressed by 32-bit or 128-bit unsigned numbers. It is a low-level protocol. Both TCP and UDP are built on it. In Java, InetAddress is used to represent the IP address. It has two subclasses: I
clearly see that the host does not have the MAC address corresponding to this IP address before it communicates with 192.168.7.119. However, after communication, now we know the MAC address of the other Party. In Windows, the MAC address of the other party is stored in the ARP cache. to save network resources and communication time, most operating systems keep an ARP cache table that records the IP addresses and MAC addresses that were previously ac
