Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the network switches decide where incoming packets are transferred to, based on the NIC's 48-bit address. Upon receipt of a packet, the switch forwards the packet to its destination port. Form factor, protocol, performance, port, and features are all important to consider when selecting network switches. |
Products & Services Related to Network Switches
Network Firewalls
Network firewalls are systems that enforce access control policy between an organization's network and the Internet for security purposes.
Network Gateways
Network gateways interconnect networks with different, incompatible communication protocols.
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 Transceivers
Network transceivers, short for transmitter-receiver, are devices that both transmit and receive analog or digital signals.
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.
