As of Packet Tracer 5.0, Packet Tracer supports a multi-user system that enables multiple users to connect multiple topologies together over a computer network. [6] Packet Tracer also allows instructors to create activities that students have to complete. [citation needed] Packet Tracer is often used in educational settings as a learning aid.
Cisco Discovery Protocol (CDP) is a proprietary data link layer protocol developed by Cisco Systems in 1994 [1] by Keith McCloghrie and Dino Farinacci. It is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address .

Following the initial design of ATM, networks have become much faster. A 1500 byte (12000-bit) full-size Ethernet frame takes only 1.2 μs to transmit on a 10 Gbit/s network, reducing the motivation for small cells to reduce jitter due to contention. The increased link speeds by themselves do not eliminate jitter due to queuing.
A packet analyzer used for intercepting traffic on wireless networks is known as a wireless analyzer - those designed specifically for Wi-Fi networks are Wi-Fi analyzers. [a] While a packet analyzer can also be referred to as a network analyzer or protocol analyzer these terms can also have other meanings. Protocol analyzer can technically be a ...
CDP is enabled by default on all Cisco routers, switches and servers. The protocol can be disabled across a network; however, if it is disabled on an interface and the encapsulation is changed, it will be re-enabled on that interface. [5] [6] The protocol is most often used to aid network administrators by finding and discovering devices easier ...
This procedure rapidly gets a copy of the latest version of each node's link-state advertisement to every node in the network. The complete set produces the graph for the map of the network. The link-state message giving information about the neighbors is recomputed and then flooded throughout the network whenever there is a change in the ...
