    Visibility From Your Network Into The Cloud: Today’s New Essentials

    The cloud is supposed to make everything simpler and more cost-effective for businesses and their users, but for network managers, it adds complexity. Cloud services are made available to users on demand via the internet. The services depend on extreme network reliability, and that reliability must extend beyond traditional corporate boundaries. 

  • The Shortfalls Of Traceroute In Modern Multi-Path Networks

    Traceroute is a fantastically popular network troubleshooting tool. It is second in popularity only to ping. The reason is simple. Traceroute quickly shows you what network devices your traffic is going through to reach a destination, and gives an indication of what each of those devices’ performance is. Theoretically, you can quickly tell where your traffic stops, where your traffic is slowed, and what devices are important for this connectivity. Not only is this super helpful, but it’s also intuitive. It aligns with our mental model of how networks work. It just makes sense.

  • VoIP Vs. Regular Phone Services: A Guide To IP Telephony

Networking refers to the range of hardware, software, processes, regulations, and protocols that make up computer and other networks. A network is a telecommunications system that allows connected devices to exchange data via cables or wirelessly (Wi-Fi). Networks provide shared access to systems, services, applications, and devices such as the World Wide Web, servers, printers, storage devices, email, messaging, and many more.

Security on networks is controlled by a network administrator through a set of provisions and policies that prevent unauthorized access to the network and network-accessible resources. Access to secured networks requires authentication usually via username and password (one-factor authentication), but can be augmented to include additional steps based on something a user 'has' such as generating a code via a security token, card, or mobile phone (two-factor authentication), and further augmented to include something a user 'is' such as a retinal or fingerprint scan. Firewalls enforce access policies on the network and anti-virus software or intrusion prevention systems (IPS) help to detect and inhibit malware and other potential threats.

Networks can be connected by electrical cable, radio waves, and optical fiber which are defined as layers 1 (physical layer) and 2 (data link layer) in the OSI model. Types of wired technologies include twisted pair wire, coaxial cable, ITU-T, and optical fiber. Wireless technologies include terrestrial microwave, satellite, cellular and PCS, radio and spread spectrum, and infrared. The basic hardware components of a network include network interface controllers (NIC), repeaters and hubs, network bridges, network switches, routers, and firewalls.

Ethernet is the most widely-adopted and used family of communications media used in local area networks (LAN), encompassing both wired and wireless network communications. IEEE 802 defines the standards and protocols that enable networked device communications. Networks can be classified by physical capacity or purpose such as personal area networks (PAN), local area network (LAN), storage area network (SAN), wide area network (WAN), virtual private network (VPN), and others.
