Embedded Network Switch Board

Embedded Network Switch Board

새로 개발된 보드는 특수 분야 산업용으로 개발한 L2 Network Switch Board입니다.

워낙 고결한(?) 분야라 부품 선정에서 부터 많이 신경을 쓴 보드입니다.

HERA-Embedded L2 Switch Board

HERA which our network switch board provide a rich set of Carrier Ethernet switching 

features such as  queue-based Ethernet services, provider bridging, protection switching, and

synchronous Ethernet. Advanced TCAM-based VLAN and QoS processing enables

delivery of differentiated services with per-service SLA guarantees. Security is assured

through frame processing using a TCAM-based integrated processor.

Overview

• HERA supports three major port configurations:

12 x1G copper PHY + 3 x QSGMII + 1 x 1G SGMII + 1 x 2.5G SGMII

12 x 1G copper PHY + 10 x 1G SGMII + 2 x 2.5G SGMII

10 x 1G copper PHY + 2 x QSGMII + 8 x 1G SGMII

General Features

• All 1G Ethernet ports are tri-speed 10/100/1000 Mbps ports

• All 2.5G Ethernet ports are quad-speed 10/100/1000/2500 Mbps ports

• Integrated copper transceivers are compliant with IEEE 802.3ab 

• SGMII ports support both 100-BASE-FX and 1000-BASE-X-SERDES

• Four megabits of integrated shared packet memory

• Fully nonblocking wire-speed switching performance for all frame sizes

• Eight priorities and eight queues per port

• Dual leaky bucket policing per queue and per port

• DWRR scheduler/shaper per queue and per port with a mix of strict and weighted queues

• 256 TCAM-based egress tagging entries

• Up to 256 TCAM-based classification entries for Quality of Service (QoS) and VLAN membership

• Up to 512 host identity entries for source IP guarding

• 256 TCAM-based security enforcement entries

• L1 Synchronous Ethernet

• L2 IEEE 1588-2008 Precision Time Protocol (IEEE 1588) with hardware-based timestamping for one-step or two-step clocks

• Energy Efficient Ethernet (IEEE 802.3az) is supported by both the switch core and the internal copper PHYs

• Audio/Video bridging (AVB) with support for time-synchronized, low-latency audio and video streaming services
