VLSM (Variable Length Subnet Mask) is a technique that network administrators employ in order to use their IP subnet(s) in a more effective manner. By using VLSM, a long mask can be used on a network that has a few hosts and a short net mask on subnets that have a large number of hosts.

SCTP (Stream Control Transmission Protocol)
The Stream Control Transmission Protocol (SCTP) is a reliable transport protocol that works on a connectionless IP packet network. It transports Public Switched Telephone Network (PSTN) messages over networks and also has other functions.
Interior Gateway Routing Protocol
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.
What is EIGRP?
Local and international networks require information to be constantly updated in order to properly route communications. Routing protocols were developed in order to help keep information flowing to the proper locations and to maintain network connectivity on both LAN and WAN.
Cisco Router Configuration
Routers are basically used to connect different networks by allowing them to exchange routing information with each other. A router is a network layer device that maintains a database called an IP routing table by learning the ip addresses of directly connected networks by default.
Understanding ISDN
What is ISDN ?
What does ISDN stand for? It is the Integrated Services Digital Network that comprised of digital telephony and data-transport services offered by regional telephone carries.
Understanding the IPX-SPX Protocol
IPX/SPX is a protocol suite that is implemented on many corporate internetworks. IPX/SPX was developed to operate in Novell Netware in LAN environment. But today, the IPX/SPX is also used in Microsoft NT, Microsoft XP and Lotus Notes environment along with Vista.
Understanding Frame Relay
Frame Relay is a protocol for transmitting data over a wide area network (WAN). It was designed to use across ISDN interfaces but it is now used over an assortment of other network interfaces. Once one becomes a master of frame relay design and configuration, it is much easier to obtain a strong understanding of x.25, ATM, and SMDS.
Understanding Ethernet
The term Ethernet refers to the family of Local Area Network (LAN) implementation. Ethernet is actually the most popular Local Area Network architecture that consists of Ethernet specifications and standards as well as Ethernet hardware devices such as Ethernet splitter, Ethernet drivers and USB Ethernet device.
Understanding Ethernet Networking
Ethernet refers to the family of Local Area Network implementation that was jointly developed by Digital Equipment Corporation, Intel Corporation and Xerox Corporation. It consists of certain specifications and standards as well as hardware devices and components.
