Types of Network Traffic Network traffic can be categorized in a number of ways according to the specific needs of the network administrator or analyst. Common categories include packet type, transmission method, packet flow, transmission protocol, QoS priority, connectivity, and source. Packet Type ...
Network traffic monitor software analyzes the flow of data across the network to help administrators understand who is using the network and for what purpose. It also provides bandwidth monitoring, which involves measuring the amount and speed of data transmission over a network to ensure optimal per...
The presented analysis tool is especially useful to compare important network load characteristics in a geographically aware display, to relate communication partners, and to identify the type of network traffic occurring. The results of the analysis are helpful in understanding typical network ...
Port mirroringUse with a network analyzer to diagnose network issues and problems. During setup, the switch exports a copy of the network traffic to a single port. Bandwidth rate-limitingAllow fine control of the bandwidth used by specific ports. For example, allowing a high bandwidth for ports...
Passive attacks involve monitoring or eavesdropping on network traffic without directly altering it. The main aim is to gather information stealthily, which can be used in future attacks. Examples of passive attacks would be packet sniffing and traffic analysis. ...
Virtual Private Network (VPN) traffic_analyzer / Getty Images A virtual private network (VPN) consists of the hardware, software, and connections needed to support protectedclient-servernetwork communications over public network infrastructure using a method called tunneling. ...
A virtual LAN (VLAN) is a type of LAN configuration that virtually groups network components into segments. Network administrators create VLANs to operate segments as individual systems, separate from the rest of the LAN. VLANs prevent network congestion by isolating LAN traffic for each segment,...
In this unit, you explore some of the common types of network topologies that are used to create internet-based networks. What is a network? A network is a collection of network-enabled devices, typically made up of computers, switches, routers, printers, and servers. Networks are a fundamen...
If there is a need of communication between different VLANs in the network, traffic flows from the lower Layer 2 switches through the core Layer 3 switch which routes the packets from one VLAN to another. 10) Data Center Switches Data Centers have seen explosive growth in recent years. Almos...
Below are eight common types of network devices -- excluding load balancers and firewalls -- that are typically found within networks. 1. Access point An access point (AP) is a device that sends and receives data wirelessly over radio frequencies, using 2.4 GHz or 5 GHz bands. Clients, su...
