Input and Output Streams
Most network engineers have been trained to think about output the wrong way. Throughput graphs show green, link utilization sits at 40%, and yet users file tickets about sluggish applications. The gap between what the network delivers and what applications actually receive is not a metric problem—it is a fundamental misunderstanding of what output means...
How Stay At A Halfway House Should Be Like?
A halfway house in networking isn’t what most IT professionals think it is. Ask a CCNA candidate what sits between a standard Layer 2 switch and a full Layer 3 router, and they’ll describe a device that does a bit of both but excels at neither. That conceptual gray zone is exactly where the term...
Static Mapping command Examination
We earlier discussed that Cisco routers support all network layer protocols over Frame Relay. We also know that the address-to-DLCI mapping can be accomplished both by dynamic or static mapping. Frame Relay static mapping ever depends on the network needs. To map between a next-hop protocol address and a DLCI destination address, the following command...
Frame Relay Address Mapping Exclusive
Cisco routers support all network layer protocols such as IPv4, IPv6, IPX, and AppleTalk over Frame Relay. For transmitting data over Frame Relay, it needs to know which local DLCI maps to the Layer 3 address of the remote destination. In simple words Frame Relay address mapping matches a next-hop IP address that sits on...
Frame Relay Encapsulation – Exclusive Explanation
As we discussed earlier, Frame Relay is working on the Datalink Layer of the OSI Model. So, it takes data packets from the upper layer of the OSI model, encapsulates the data into the Frame Relay frame, and then passes the frame to the physical layer of the OSI Model for delivery on the network....
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) are a logical connection between two data terminal equipment (DTE) devices across a Frame Relay packet-switched network (PSN). The circuits...
