Polling checks a remote network device or service availability via a SNMP protocol and report the information found on the network device and /or service back to the system where polling was initiated.
It is known as polling.
SNMP (Simple Network Management Protocol) offers several advantages, including efficient network monitoring and management, standardized communication across different devices, and the ability to gather real-time data for performance analysis. However, it also has disadvantages, such as security vulnerabilities due to its limited authentication mechanisms, the complexity of configuration and management in large networks, and potential performance overhead from frequent polling of devices. Overall, while SNMP is valuable for network administration, careful consideration of security and scalability is essential.
An SNMP trap is a notification sent from a network device, such as a router or switch, to a management system indicating that a specific event or condition has occurred. Unlike SNMP polling, where the management system requests information, traps are unsolicited messages triggered by events like device failures, threshold breaches, or performance issues. This allows for real-time monitoring and quicker response times to potential problems in the network. Traps are part of the Simple Network Management Protocol (SNMP), which is widely used for managing networked devices.
When a host system stars,it sends requests to all ports.This is called device polling. Then the s/m polls the device continuously. In USB3.0 like devices continuous polling is avoided to increase power efficiency.Instead of continuous polling asynchronous notifications are used.
equal access to the medium for all computers on the network
Computer network Polling is where a client server or Network Hub polls each computer for data. Data can only be sent when the particular computer is polled. If the computer has data to send but is not polled at that time, the data has to be stored until it can be sent. ^_^ JunkCollector ^_^
Polling.
I presume as in electronics and computer and in that case polling is amaintenance task that is pre program to service devices at period times
When the microprocessor receives an Interrupt Service Request (ISR) on the interrupt line it must determine which of the devices connected to that input sent the request.Software Polling is one method by which it can do so.In Software Polling:A software routine is used to identify the device requesting service. It does so by checking each device to see if it was the one needing service.
In a network with one primary and four secondary stations using polling, the primary station controls communication by sequentially polling each secondary station to check if it has data to send. This method ensures organized access to the shared medium, preventing collisions and allowing efficient data transmission. The primary station typically allocates time slots for each secondary station, optimizing the use of the network resources. If a secondary station has no data to send, it simply informs the primary, allowing the primary to move on to the next station.
The polling booth was hacked during the elections.We need to be at the polling both by midday.
