Introduction An entreprize network is an instance of an autonomous systems. An autonomous system or AS, as it is also commonly known, is a connected group of one or more IP prefixes run by one or more network operators which has a SINGLE and CLEARLY DEFINED routing policy. In the evolution phase of networking, the […]
Versatile Routing Platform(VRP)
Versatile Routing Platform(VRP) It is a Command Line Interface which is used for configuration, management and monitoring of devices. It is based on a standardized and hierarchical command line system. Huawei devices use eNSP software for this purpose. The command line interface The command line interface has four command views: They are: User View: The […]
Single Switched Network
Single Switched Network The shift is from a single collision domain towards the multiple collision domain which is possible because of evolution of network technology such as switch and the 100 base-T form of media. This has has isolated as transmission and reception on two separate wires. No collision hence no need for CSMA/CD. […]
Rapid Spanning Tree Protocol
Rapid Spanning Tree Protocol RSTP was introduced to overcome the limitations of the spanning tree protocol (STP). Advantage of STP: Though STP ensures a loop-free network. Problem with STP: With increased topology changes, STP slows down the network topology convergence speed, leading to service deterioration causing regular interruption. RSTP employs a proposal and agreement […]
Spanning Tree Protocol
Spanning Tree Protocol As a enterprise networks expands it require more number of switches. Switches are a point-to-point interconnections via end systems are able to forward frames to destinations located via other switches within the broadcast domain. The failure of one switch or its link results in the immediate isolation of the downstream connectivity. In […]
IP Addressing
IP Addressing IP addressing is the role of the layer-3 ‘Network Layer’ in OSI Model or Layer-2 ‘Internet layer’ in TCP/IP model. IPv4 Header The IP header is used to support two key operations, routing and fragmentation. Routing is the mechanism that allows traffic from a given network to be forwarded to other networks, since […]
Ethernet Framing
Difference between protocol and standards
Protocol A protocol is a particular set of rules for having a conversation between two computers to convey a specific set of information. It is an agreement between the communicating parties on how the communication is to proceed. Violating the protocol will make the communication more difficult. An example of protocol would be TCP/IP. The specifics of the above […]

Divide by N Counter Design
Design of a divide by N counter A divide by N counter counter N number of state following which it resets back to the initial state and starts counting again. For example, a divide by 10 also known as a decade counter counts a total of 10 states from 0 to 9 before resetting to […]
