RS-125 Product Brief
The RS-125 is a special purpose network processor for r e m o t e bridging and bandwidth allocation applications. It is designed to be integrated into business and residential broadband access devices. Ethernet Processing at up to 100 Mbps The RS-125 provides Ethernet processing at full wirespeeds of up to 100 Mbps full-duplex. Bridging with 10,000 MAC Addresses The RS-125 provides wire-speed layer-2 bridging by automatically learning the MAC addresses of the LAN on which it is connected and forwarding only those packets destined for the remote side. It can forward at 300,000 pps and filter at 150,000 pps without dropping packets. The LAN table can support up to 10,000 MAC addresses. Automatic Bandwidth Allocation In addition to bridging the RS-125 can be set to monitor active data flows and maintains a list according to MAC addresses or VLAN IDs. As such it automatically allocate an equal share of the bandwidth to each flow. When a new flow is added to the list, or dropped due to aging, the active flows continue to get an equal share of the available bandwidth although the proportion changes. For example when 5 flows are active, each flow gets at least 20% of the bandwidth, when 4 flows are active each flow gets at least 25%. When a flow does not use its share of bandwidth, its unused bandwidth is shared equally amongst the other flows. `Drop-in' Solution The RS-125 is a `drop-in' solution, with no software development required. It operates independently without the need for a host processor. The RS-125 works with industry standard SDRAM. It uses low power 0.18m CMOS technology and is available in two package options: 240-pin QFP or 228 BGA.

Block Diagram
The RS-125 has two interfaces: Subscriber and Ser vice. The Subscriber Interface is an Ethernet R/MII. The Service Interface can be configured to operate as either HDLC or R/MII. All interfaces can operate at up to 100 Mbps. The RS-125 works with industr y standard SDRAM, ROM and Flash Memory.
