Gigabit Ethernet Switch

As 1553 bandwidth is filled and aircraft are integrating multi function displays, moving maps, and multiple full rate video feeds, integrators are looking for an easy way to implement Gigabit Ethernet.

Designed and produced by Aeronix, Inc. of Melbourne, Florida, the Gigabit Ethernet Switch (GES) is intended for use in hostile military environments.

The Aeronix GES provides twelve Gigabit Ethernet ports and two RS-232 management ports. Its rugged monolithic design is intended to operate in severe environments without the need for forced air cooling. This allows integrators to worry about what to do with all of the data instead of how to move it around.

The GES is a 12 port Gigabit Ethernet switch which has been designed specifically for integration into aircraft where weight, size, and power are all of the highest priority. At less than 3 pounds and with dimensions of 8.25” x 5.1” x 1.38”, the GES is very compact which allows it to fit into spaces previously unusable for rugged, gigabit class switches. With an average power consumption of 16 watts with all 12 ports active, the GES is very low power which allows for ambient air cooling. Meeting MIL-STD-704A power specifications and shock/vibration qualification to aircraft gun fire levels, the GES will operate through the worst that your application can dish out.

The small footprint of the GES is not at the cost of functionality. At the heart of the GES is a fully manageable switch fabric which includes support for VLAN’s, QoS, Link Aggregation, IPv6, and Ingress/Egress monitoring.

The GES contains an in-band ARM9 management processor which will allow custom management functions as required by the integrator. A serial port is also available in the form of an Ethernet to serial bridge which allows control of legacy equipment from anywhere in the network.

Capabilities

The GES is based on two eight port 10/100/1000 QoS Ethernet Switch ICs The following list is a sub-set of the capabilities of the Switch IC’s:

Egress tagging/untagging - selectable per port or by 802.1Q VLAN ID

Port Based VLANs - supported in any combination or 802.1 VLAN support for 4096 VIDs

Port States and BPDU handling for spanning tree

802.1X Source MAC address authentication

Quality of Service - switch architecture provides non-blocking switching in all traffic environments

Link Aggregation (802.3ad) - allows two or more links to be trunked to increase the total bandwidth and provide a fail safe if one of the links fails

A high speed, non-blocking, QoS switch fabric with support for four traffic classes based on:

  • Port
  • IEEE 802.1p
  • IPv4’s TOS or Diff-Serv
  • IPv6’s Traffic Class
  • 802.1Q VID
  • DA MAC address
  • SA MAC Address
  • Back-pressure flow control on half-duplex ports
  • Pause-frame flow control on full-duplex ports
  • Lookup engine supports 1024 MAC address entries with learning and aging
  • Auto-MDI/MDIX and polarity correction

All of these features can be accessed thru the Aeronix GES Programming Fixture (P/N AE100937-001).

The Management Processor in the GES is an ARM9 running at 96 MHz. It is directly connected to a dedicated in-band Ethernet port on the Switch IC’s. It is capable of running a TCP/IP stack so that it can be an active participant on a network serviced by the GES.

Aeronix can create custom loads for this processor that will allow increased GES management functionality and/or customer defined custom applications that would be hosted on this processor. This processor, after startup, only services the Maintenance port, thus it is only lightly loaded.
