Information about Network Gateways

Network gateways interconnect networks with different, incompatible communication protocols. Network gateways perform layer-7 protocol-conversion to translate one set of protocols to another (for example, from TCP/IP to SNA or from TCP/IP to X.25). A gateway operates at OSI layers up through the Session Layer. Form factor, network type, performance, port, processor specifications, memory, and features are all important specifications to consider when searching for network gateways.

Products & Services Related to Network Gateways

Network Equipment

Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).

Network Firewalls

Network firewalls are systems that enforce access control policy between an organization's network and the Internet for security purposes.

Network Hubs

Network hubs serve as the central location for attaching wires to workstations.

Network Repeaters

Network repeaters regenerate incoming electrical, wireless or optical signals to preserve signal integrity and extend the distance over which data can travel. They are often used to connect cable segments in IEEE 802.3 networks.

Network Routers

Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.

Network Switches

Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.

VoIP and IP Telephony

VoIP and IP telephony allows PC users to make phone calls over the Internet or other packet networks via gateways and standard telephones.
