The Interior Gateway Routing Protocol (IGRP) is a network routing protocol that is designed to enable routing inside of an Autonomous System (AS). Cisco developed this protocol in the late 1980s in response to the existing Routing Information Protocol’s (RIP) shortcomings. As Cisco routers became more popular, a number of large networks began using IGRP, …
Cisco Network Management Overview of Network Management Different people may take network management as different meanings. It may be considered as solitary network consultant for monitoring network activity using outdated protocol analyzer. While network management in distributed database environment, managing network nodes for generating real time graphics and auto polling of network devices. There are …
PuTTY is an open source terminal emulation program that accesses Telnet, SSH, and other TCP protocols and acts as a serial client for computers. The letters “TTY” in the name PuTTY represent the terminal application in the Unix and Linux Operating Systems (OSs) and is also short for teletype. The PuTTY application was first written …
Subnetting is the process of breaking down an IP network into smaller sub-networks called “subnets.” Each subnet is a non-physical description (or ID) for a physical sub-network (usually a switched network of host containing a single router in a multi-router network). In many cases, subnets are created to serve as physical or geographical separations similar …
Cat 6 (Category 6) is a cable standard used mainly for Ethernet computer networking, security systems, and telephone services. Cat 6 cable is backward compatible with the Cat 5, Cat 5E, and Cat 3 cable standards. Category 6 cable is capable of transmitting voice and data up to 155 Mbps (mega bits per second), with …
Broadband has revolutionized the way we view and use the internet. The two main types of broadband technology that have pervaded the market are Asymmetric Digital Subscriber Line (ADSL) and cable modems. Both these technologies are a huge leap from the days of the 56 Kbps dial-up connections, with maximum speeds ranging between 8 to …
Windows Server 2003 and Windows XP support the following PPP authentication protocols: PAP or Password Authentication Protocol The oldest forms of authentication schemes used where the user credential are sent in plain text. This is not the securest form of passing authentication credentials as anybody can use a third party sniffer program and capture these …
A USB WiFi antenna is a device that provides a computer with access to the Internet when in range of a WiFi access point. It also refers to a USB-based wireless adapter that also provides a computer with Internet access but connects to specific wireless routers rather than public WiFi access points. USB WiFi antennas …
VLAN (Virtual Local Area Network) is a logical local area network (or LAN) that extends beyond a single traditional LAN to a group of LAN segments, given specific configurations. Since a VLAN is a logical entity, its creation and configuration is done completely in software. How is a VLAN Identified? Since a VLAN is a …
VRRP stands for Virtual Router Redundancy Protocol. The VRRP is a commonly used method to avoid network outages during important data transfers. Data transfer can be highly susceptible to failure when sent by a single router network. To combat this problem, VRRP creates a virtual connection between routers within the same network and ties them …
