Multiple Virtual Circuits (VCs) – Briefly Explained

Table of Contents

Networking Devices 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 […]

Frame Relay Virtual Circuits (VCs) – Exclusiv Explanation

Networking Devices 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 […]

How to Configure Challenge Handshake Authentication Protocol (CHAP)

Challange-Handshake-Authentication-Protocol-CHAP

Networking Devices 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 […]

Password Authentication Protocol (PAP)

Networking Devices 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 […]

PPP Configuration

Networking Devices 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 […]

LCP Options

Networking Devices 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, […]

HDLC Encapsulation Protocol

Networking Devices Earlier in the previous article, I have discussed that HDLC is the default encapsulation protocol type on point-to-point connections, dedicated links, and circuit-switched links when the link uses two Cisco devices. It is a synchronous Data Link layer bit-oriented protocol originally developed from the Synchronous Data Link Protocol (SDLC) and became standardized by ISO […]

WAN Encapsulation Protocols

Networking Devices Network layer passes the data to the data link layer for transmission over the physical layer. The Data Link layer creates frames by adding the necessary checks and controls around the Network layer data. The encapsulation on a router serial interface must be configured to guarantee the correct encapsulation method is used. Different […]

Serial Cable

Networking Devices Serial cable is used to interconnect DTEs and DCEs. The DCEs are data communication equipment that generated or received data, and the DCEs are data communication equipment that only relayed data. There are two different types of cables, one for connecting a DTE to a DCE, and another for connecting two DTEs directly […]

Statistical Time-Division Multiplexing (STDM)

Networking Devices Statistical time-division multiplexing (STDM) is sharing a communication like TDM but like the TDM the time slots are not allocated to any channel. In the case of TDM, time slots are allocated to channels and reserved even if there is no data to send. This allocation is just wastage of the bandwidth and […]

Why Are Every Start-up Using Fleet Management Software to Grow their Business?

Networking Devices Sponsored Managing enterprise fleets and their day-to-day operations are Hercules tasks for fleet managers. Most of the fleet managers still use paper and pen for the trip plan excel sheets for vehicle and driver details, above all communicate with drivers using phone calls and messages. To improve the productivity and process the enterprise […]

Networking Devices Network devices are physical devices that are required for communication and interaction between hardware on a computer network. The network devices work as a group and have a single purpose which securely transfers data as fast as possible. To meet this goal there are several network devices like repeater, bridge, hub, switch, router […]

Networking Devices We can all feel a big change on the horizon of world. Enduring the challenges of 2020-2021 has really opened everyone’s perspective to what they do and do not want out of their lives, and that mindset shift has our society in a position where our core values are changing. No longer do […]
