How Routing Protocols Work

Every network routing protocol performs three basic functions: discovery – identify other routers on the network route management – keep track of all the possible destinations (for network messages) along with some data describing the pathway of each path determination – make dynamic decisions for where to send each...

What is Router?

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. In packet-switched networks such as the internet, a router is a device or, in some cases, software on a computer, that determines the best way for a packet...

what is MPLS?

MPLS stands for “Multi-Protocol Label Switching” Multiprotocol Label Switching (MPLS) is a type of data-carrying technique for high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels...

What is Bit Error Rate (BER)

Bit error rate, BER is a key parameter that is used in assessing systems that transmit digital data from one location to another. The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided...

Characteristics of TDMA (TIME DIVISION MULTIPLE ACCESS)

Characteristics of TDMA: Shares single carrier frequency with multiple users. Non-continuous transmission makes handoff simpler. Slots can be assigned on demand in dynamic TDMA. Less stringent power control than CDMA due to reduced intra cell interference. Higher synchronization overhead than CDMA. Advanced equalization may be necessary for high data...
