Product Summary

RAD's TinyRouter miniature wirespeed IP router and extender is a low cost high performance device intended for connecting LANs at wirespeed up to 1.3 kilometers (4265 feet). The TinyRouter miniature wirespeed IP router and extender can be used as a Frame Relay Access Device (FRAD) with an integral IP router. TinyRouter miniature wirespeed IP router and extender supports IP multicast at wirespeed, making the unit suitable for any multicast environment including high-speed downstream environments, such as satellite and xDSL.

Benefits

• Low cost, plug and play device • Compact device saves space in crowded equipment closets

Further Product Information

TinyRouter and TinyRouter-4W are high performance, miniature IP routers. Their small size and low cost make them ideal for cost-sensitive routing applications or as LAN extenders or segmenters over bitstream-type infrastructures.

Advanced IP routing features ensure swift, accurate packet delivery

TinyRouter and TinyRouter-4W work by taking each Ethernet frame from the LAN and determining whether or not the IP packet is destined for the IP network on the Ethernet LAN. If not, they forward the packet to the WAN link. IP packets received on the WAN are automatically forwarded to the LAN if the IP network matches. The devices include hardware filters that handle all filtering operations at wire-speed from both LAN-to-WAN and WAN-to-LAN, without dropping a single packet. Routing is performed at the maximum rate of 30,000 frames per second (wire speed). The buffer can hold 256 full-sized frames with a throughput latency of one frame. TinyRouter and TinyRouter-4W are available with 10Base5 (AUI) or 10BaseT (UTP) interfaces. The 10BaseT interface can also operate in full duplex Ethernet applications. TinyRouter offers a choice of WAN interfaces, including V.24, V.35, V.36, X.21, RS-530 or a built-in fibre optic modem. The WAN link operates transparently in simplex, half duplex or full duplex modes. TinyRouter-4W extends the LAN over 4-wire to 1300m (4265 ft) when operating at 5 Mbps and up to 500m (1640 ft) when operating at 10 Mbps. Variable link speeds up to 10 Mbps are supported transparently. Link speeds may be adjusted "on-the-fly" without any effect on the TinyRouter or TinyRouter-4W. In addition, they provide hardware-based traffic throughput control.

Serves as FRAD device

The devices can also be used as Frame Relay access devices (FRADs) with an integral IP router. RFC 1490 is supported for a single DLCI on the WAN link. Autodiscovery of the DLCI and the maintenance protocol is performed automatically. This allows TinyRouter or TinyRouter-4W to be used as the termination unit of IP services over Frame Relay at the customer premises opposite a Frame Relay switch in the backbone. Alternatively, Point-to-Point Protocol (PPP) can be run on the WAN link with automatic negotiation on power up. With this feature, the devices can operate in conjunction with any PPP-compliant access server or backbone router. A third alternative for the WAN protocol is standard HDLC, which is especially important for broadcast and multicast applications. TinyRouter and TinyRouter-4W also support IP multicast at wire speed, making them suitable for any multicast application, including high speed downstream environments such as satellite and xDSL. Management and advanced configuration are achieved using Telnet and SNMP.
