5012R, the industry's first Fast Ethernet repeater controller chip to integrate remote monitoring (RMON) management support.

The BCM5012R operates as a hardware accelerator for RMON, giving manufacturers a cost-effective, integrated hardware solution for improving the performance of RMON management support in network equipment.

Developed by the Internet Engineering Task Force (c/o Corporation for National Research Initiatives (CNRI), Reston, VA, Founded in 1986, the IETF is a non-membership, open, voluntary standards organization dedicated to identifying problems and opportunities in IP data networks and proposing technical solutions to the  (IETF See Internet Engineering Task Force.

), RMON provides traffic statistics and analysis for comprehensive network fault diagnosis, planning and performance tuning. In complex network environments, where there are multiple network segments, RMON can reduce network administration time by up to 60 percent.

For an Ethernet topology, the RMON standard consists of nine groups. The BCM5012R carries out the statistics group, which is an enhanced management information block (MIB (1) (Management Information Base) The hierarchical database used by the simple network management protocol (SNMP) to describe the particular device being monitored. MIB objects are identified using ASN.1 syntax. See SNMP, RMON, OID and ASN.1. ) for categorizing network events, where updates occur in real time on a per-packet basis.

 from performing this compute-intensive task reduces the complexity and cost associated with developing Fast Ethernet equipment with RMON management support.

The BCM5012R eliminates the need for powerful CPUs and reduces the software development time and the size of the software management code associated with supporting RMON protocols in network equipment.

The BCM5012R is compliant with the IEEE 802.3u standard for Fast Ethernet. Broadcom's repeater controller contains 13 repeater ports and can support any port with 100BASE-TX, 100BASE-T4 and 100BASE-FX connections.

The BCM5012R has a dedicated port connection for a local MAC, which provides manufacturers with a simple connection to MAC management or to an uplink bridge. In addition to integrated RMON management support, the BCM5012R has integrated simple network management protocol (SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. ) support, which is the legacy statistical tool used for identifying network hardware problems.

For manufacturers looking for a lower cost repeater controller solution, Broadcom is also introducing the BCM5010. The BCM5010 is pin and functionally compatible with BCM5012R, but it does not have management support. The BCM5010 is ideal for manufacturers developing equipment for cost-sensitive environments that do not require network management support.

Coupled with IEEE (Institute of Electrical and Electronics Engineers, New York, A membership organization that includes engineers, scientists and students in electronics and allied fields.  802.3 standard phy chips for Fast Ethernet, the BCM5012R or BCM5010 can be designed into stand-alone and stackable repeater hubs, chassis-based repeater modules and interface repeaters to Fast Ethernet switch ports. Broadcom's repeater controllers are currently being used in products from 3Com Corp., Compaq, UB Networks and other leading network manufacturers.

In 1,000-piece quantities, the BCM5012R price is $108, and the BCM5010 price is $72. Both chips are packaged in a 208-pin PQFP (Plastic Quad Flat Package) Refers to many varieties of QFP chip packages, which are molded in plastic. See QFP.  and are available now in volume production.
