In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. It serves as the default gateway for all network devices. Enterprise network systems may require many internal network segments. A device wishing to communicate with a host on the public ...
In computer networking, the default route is a configuration of the Internet Protocol (IP) that establishes a forwarding rule for packets when no specific address of a next-hop host is available from the routing table or other routing mechanisms. The default route is generally the address of another router, which treats the packet the same way ...
In computer networking, the Hot Standby Router Protocol ( HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway. Version 1 of the protocol was described in RFC 2281 in 1998. Version 2 of the protocol includes improvements and supports IPv6 but there is no corresponding RFC published for this version.
The Virtual Router Redundancy Protocol ( VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork .
Router (computing) Rack containing a service-provider–class router connected to multiple networks. A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [2] [3] [4] A router is connected to two or more data lines from different IP networks.
Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their destination computer. Routing algorithms determine the specific choice of route. Each router has a prior knowledge only of networks attached to it directly.
Systems Network Architecture [1] ( SNA) is IBM 's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software. The implementation of SNA takes the form of various communications packages ...
Open Shortest Path First ( OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the ...
