Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
The Cisco 2500 series routers are a series of 19" rack mount access routers typically used to connect Ethernet or Token Ring networks via ISDN or leased serial connections (i.e. Frame Relay, T1 etc.). The routers are based on a Motorola 68EC030 CISC processor. [1] This line of routers is no longer sold or supported by Cisco Systems. [2]
NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion.

The CRS-3 is the second generation of the CRS series launched in March, 2010. In CRS-3 each line card slot has a capacity of 140 Gbits/s, which is more than three times the capacity of the previous CRS-1 generation. The architecture is retained as in the previous generation and hardware is compatible with the CRS-1 system.
High-level design (HLD) explains the architecture that would be used to develop a system.The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces.
Some multicore processors integrate dedicated packet processing capabilities to provide a complete SoC (System on Chip). They generally integrate Ethernet interfaces, crypto-engines, pattern matching engines, hardware queues for QoS and sometimes more sophisticated functions using micro-cores. All these hardware features are able to offload the ...
3.2 – first generally available version for the 12000 router series 3.9 – first generally available version for the ASR 9000 router series 5.0 – first generally available version for the NCS6000 series, which is based upon a Linux kernel instead of QNX, and was released in September 2013 [ 5 ]
