Upgrading and Repairing Networks, Fifth Edition is the definitive guide for anyone with a network, from home networking enthusiasts to professional network administrators. The book explains network architectures and protocols using plain English and real-world examples, and gives valuable insight for fixing network problems. This updated edition includes the latest on network planning and design, and building a network using wired, wireless, or both technologies. It covers the latest updates in Windows XP Service Pack 2, as well as Gigabit Ethernet, virtual LANs, Bluetooth, WAP, security, firewalls, and VPN use.
Fibre Channel (or IP 170 Chapter 11 Network Attached Storage and Storage Area Networks SAN network) can satisfy the server’s requests faster than local SCSI attached storage, often allowing a SAN to perform backup operations with very little or no noticeable impact on the clients. ■ The Fibre Channel protocol and associated hardware devices are the main choice for SANs implementers today. However, a newer technology, called IP SANs, promises to offer about the same performance as a Fibre.
(SOHO) network users, there is an entire chapter devoted to your network. Because many SOHO networks are operated by small business owners, this chapter can help you understand more complex topics without having to read this entire book. Off-the-shelf cable/DSL routers and inexpensive firewall solutions might make you feel comfortable about your network, but everyday there are new threats that can make your small network a target. Part X, “Upgrading Network Hardware,” is a valuable reference for.
Of equipment. In other words, you need to document your network. In Chapter 3, “Network Design Strategies,” you can learn about several applications and techniques that can be used to assist you in keeping track of your cable installations, as well as other components in your network. Work Orders Work orders should record all equipment and cabling moves, adds, and changes. This should form a history of the cabling system’s life or evolution. The records of the pertinent equipment involved should.
Inventory of software and hardware for systems on the network, and allows polling computers to get this information. The Wired for Management (WfM) Initiative and Wake on LAN (WOL) Technology Chapter 7 111 This means that a computer which hosts a database of the software and hardware components for other computers in the network can periodically query other computers on the network to ensure that those computers do indeed have the hardware/software components installed that the Asset.
And sends frames on their merry way. Others are hardware-based and can perform much better because no single component, such as a CPU, can be bogged down when too much traffic passes through the switch. Two basic modes of operation can be used by a switch when it forwards a packet out of a selected port: cut-through mode and store-and-forward mode. Switch Hardware Types Chapter 8 133 Cut-Through Switches A cut-through switch begins transmitting the incoming frame on the outgoing port after.
