The router gives traffic direction functions on the internet. A router inspects a given data packet's destination Internet Protocol address (IP address), calculates the best way for it to reach its destination and then forwards it accordingly. Routing Information Protocol (RIP) - the original protocol for defining how routers should share information when moving traffic among an interconnected group of local area networks. A router is a piece of hardware (or software) that receives, filters, and sends data packets across networks. In contrast, a virtual router is a software instance that performs the same functions as a physical router. Branch routers often provide additional features, like time-division multiplexing, wireless LAN management capabilities and WAN application acceleration.
