A next-generation firewall (NGFW) is a network security device that provides capabilities beyond a traditional, stateful firewall. While a traditional firewall typically provides stateful inspection of incoming and outgoing network traffic, a next-generation firewall includes additional features like application awareness and control, integrated intrusion prevention, and cloud-delivered threat intelligence.
The main benefit of an NGFW is the ability to safely enable the use of Internet applications that empower users to be more productive while blocking less desirable applications. Next generation firewalls achieve this by using deep packet inspection to identify and control applications regardless of the IP port used by the application.
A new request is sent to the server with the fewest current connections to clients. The relative computing capacity of each server is factored into determining which one has the least connections
Sends requests to the server selected by a formula that combines the fastest response time and fewest active connections. Exclusive toTrace Networks.
Distributes requests based on a key you define, such as the client IP address or the request URL. Trace Networks can optionally apply a consistent hash to minimize redistribution of loads if the set of
Random with Two Choices
Picks two servers at random and sends the request to the one that is selected by then applying the Least Connections algorithm
