产品详细信息

Multi-gigabit automotive ethernet switch platform with strong AVB/TSN capabilities intended for testing and analysing onboard vehicle networks.

支持AVB/TSN功能的多通道千兆车载以太网交换机，用于各种100/1000BASE-T1测试和车载网络分析。

With the constant need for higher bandwidth in the in-vehicle network, the Enhanced Ethernet Switch product family of Technica Engineering allows the users to connect up to 8x gigabit ethernet ports and 2x 1Gb/10Gb ports available through SFP+ connectors

随着车载网络对更高带宽的不断需求，Technica Engineering的增强型以太网交换机产品系列允许用户通过SFP+端口连接多达8个千兆以太网端口和2个1Gb/10Gb端口

The EES product family has three variants that cover the possibility to select physical layer protocol as well as connectors for the 8x gigabit ports of the switch. Options currently include variants with automotive ethernet gigabit ports and MATEnet or H-MTD connectors as well as a variant with regular IEEE 1000BASE-T ethernet ports on RJ-45 connectors.

增强型以太网交换机（EES）产品系列有三种型号，根据物理层协议以及交换机8x千兆端口的连接器划分。目前的选项包括带有汽车以太网千兆端口(1000BASE-T1)的MATEnet或H-MTD连接器型号，以及带有RJ-45连接器上常规IEEE 1000BASE-T以太网端口的型号；

They can establish virtual point-to-point connections, using single tagged VLANs (802.1q) and double-tagged VLANs (802.1q-in-q), thus enabling filter and control over data streams. Each port provides 8-levels of Quality of Services (QoS) classes and advanced traffic filtering capabilities with ingress and egress rules, which ensures the prioritization, resource reservation, and control mechanisms over the data received.

它们可以使用Single VLAN（802.1q）和Double VLAN（802.1q-in-q）建立虚拟点到点连接，从而实现对数据流的过滤和控制。每个端口提供8个级别的服务质量（QoS）类和高级流量过滤功能以及入口和出口规则，确保对接收到的数据进行优先级排序、资源保留和控制机制。

Through an internal configuration website, the user can easily configure the device for their use cases, abstracting the complex underlying switch hardware. This includes: VLANs, port mirroring, forwarding or filtering, deep inspection through TCAM rules, port segmentation, and many other features offered by Layer 2 switches.

通过一个自带配置网页，用户可以轻松地根据需求配置设备，抽象出复杂的底层交换机硬件。这包括：VLAN、端口镜像、转发或过滤、通过TCAM规则的深度检查、端口分段以及第层交换机提供的许多其他功能

The Enhanced Ethernet Switch provides a reliable gPTP/802.1AS automotive profile stack for time synchronization that allows strong customization possibilities to adapt to any customer use case. Our product is also capable of Audio Video Bridging (AVB) functions with the possibility to statically configure stream reservation and shaping features (802.1Qav).

增强型以太网交换机（EES）为时间同步提供了可靠的gPTP/802.1AS协议支持，允许强大的定制可能性，以适应任何客户用例。我们的产品还具备音频视频桥接（AVB）功能，可以静态配置流保留和整形功能（802.1Qav）

The Enhanced Ethernet Switch is also prepared for additional TSN functionalities support: 802.1Qav, Qci, Qbv, and Qbu. Customer specific use cases can be supported, if needed. Contact the Technica Engineering sales team for additional information.

增强型以太网交换机（EES）还可用于支持其他TSN功能：802.1Qav、Qci、Qbv和Qbu。如果需要，可以支持特定于客户的需求。如有需要，请联系我们。

The product also provides wake-up and sleep features.

该产品还提供唤醒和睡眠功能

网页操作界面

交换机端口配置：不同分组端口间，以不同的颜色区分；

配置界面可以直接反映出端口配置的关系

端口分组(Port Segmentation)，可以直接在这个端口矩阵上进行分组配置，并且可以通过颜色及连线方便的查看目前分组状态

VLAN 配置：

报文过滤设置，可以通过MAC地址、VLANID等多种参数进行报文过滤

报文过滤设置，还可以通过直接编辑报文具体字节：

Stream Reservation: 通过端口、MAC地址、VLAN等，限定具体通道、报文的流量；

Address Resolution Table 配置：

802.1AS (gPTP)时钟同步设置，用户可以对每个端口进行gPTP时钟设置，包括Slave, Bridge等；除了可以外接Grand Master, EES本身也可以提供主时钟；并且根据用户需求可以提供多个主时钟；

篇幅所限，只能放些典型的配置界面；如果能实际操作配置界面，还会发现EES的配置功能有很多动画的功能，功能虽然很强大、很复杂，但配置起来很轻松。
