Multiple Virtual Circuits (VCs) – Briefly Explained
Frame Relay is a multiplexing technique that transmits only one frame at a time. Multiple virtual circuits can be used on a single physical line. The Frame Relay Access Device (FRAD), or router connected to the Frame Relay network, may have multiple virtual circuits linking it to different endpoints. Multiple VCs on a single physical […]
Frame Relay Virtual Circuits (VCs) – Exclusiv Explanation
We have already discussed Frame Relay in the previous lessons What is Frame Relay? Exclusive Introduction that it provides connection-oriented data link layer communication using a Frame Relay virtual circuit. Frame Relay Virtual Circuits (VCs) is a logical connection between two data terminal equipment (DTE) devices across a Frame Relay packet-switched network (PSN). The circuits are […]
How to Configure Challenge Handshake Authentication Protocol (CHAP)
Challenge Handshake Authentication Protocol (CHAP) periodically checks the character of the far off hub utilizing a three-way handshake. The hostname on one switch must match the username the other switch has designed. The passwords should likewise coordinate. The password value is variable and changes unpredictably while the link exists. When the PPP link establishment phase […]
Password Authentication Protocol (PAP)
PPP support different option that can be configured optionally. One of these options is authentication. Authentication option provides a method to negotiate the use of a particular protocol for Authentication. By default, authentication is not required. Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) can be used for PPP links authentication which is defined […]
PPP Configuration
Remember that HDLC is the default encapsulation protocol for Cisco routers. If PPP configuration is not done on Cisco routers, the default encapsulation will be used. To set PPP as the encapsulation method used by a serial interface we need PPP configuration on the serial interfaces. The PPP configuration for the below topology is following. […]
LCP Options
PPP support different option than can be configured optionally. Authentication using PAP or CHAP, Compression using either Stacker or Predictor and Multilink that combines two or more channels to increase the WAN bandwidth. To negotiate these PPP options, the LCP link-establishment frames contain option information in the data field of the LCP frame, as shown […]
Time Division Multiplexing (TDM)
Multiplexing is a technique that allows multiple logical signals to share a single physical channel. The two common types of multiplexing are time-division multiplexing (TDM) and statistical time-division multiplexing (STDM). In this article, I am going to discuss the time-division multiplexing. Time Division Multiplexing (TDM) transmits more than one streaming digital signals over a common […]
Point to Point Communication Links
Usually, a point to Point links is used when permanent dedicated connections are required. It is a pre-established WAN communications path connection, which can securely connect two or more locations for private data services. The point to point links is available with different standards and different speed including T1 lines, Ethernet or DS3. Enterpriser usually […]
Serial Communication
Serial communication is the famous and broadly used technique to transfer data between processing equipment and peripherals. Serial communication is used to transfer data across the WANs. The sending router encapsulates the data using a communication protocol. The encapsulated data is sent on a physical medium to the WAN and receiving router de-encapsulates the encapsulated data […]
Parallel port
Parallel ports usually used for connecting printers, computers, and other devices that required high bandwidth. The port is also used for interconnection between interior components of the devices. Parallel ports can be transmitted simultaneously over multiple wires. Theoretically parallel port is eight-time faster than a serial port. The serial port sends one bit while at […]
IPv4 Classful Network Exclusive Explanation
A classful network is a network addressing architecture used in the networks since 1981.The RFC 790 and 791 released in 1981 describing how IPv4 network addresses were primarily allocated based on a classification system. The authors of IPv4 addresses set up three classes of network addresses, class A, B, and C for different network sizes. […]
Plastic Business Cards: Advantages and Uses
Marketing your business is always required and there are different tools and strategies you can use to do so. One way among them is integrating full-color plastic cards into your overall marketing plan, and is a perfect way to differentiate your business from the flood of paper marketing materials. Plastic cards can be used to […]
How PC Power Supplies Work
In the event that there is any one part that is totally imperative to the activity of a PC, it is the force supply. Without it, a PC is only an idle box brimming with plastic and metal. The Cisco Power Supply changes over the exchanging current (AC) line from your home to the immediate […]
Network-Attached Storage | Its Function
Network-Attached Storage (NAS) is a document level stockpiling design that makes put away information more open to arranged gadgets. Shop online Dell NAS Storage at the best price. NAS is 1 of the 3 fundamental stockpiling structures—alongside capacity territory organizations (SAN) and direct-joined capacity (DAS). NAS gives networks a solitary passage for capacity with work […]
