What is an IP address?

IP 地址（互联网协议）是网络中每个设备的唯一标识符。每个 IP 报文中都包含源设备和目的设备的 IP 地址。IP 地址由四个字节组成（例如 192.10.0.5）。IP 地址分为两部分：网络部分和计算机部分。IP 地址可以由服务器等服务器设备或受管以太网交换机手动或自动（DHCP）分配。如果您对我们的以太网交换机和媒体转换器有任何疑问，请联系我们的技术支持团队。

What is the MAC address?

MAC = 媒体访问控制每个以太网设备都有一个唯一的 MAC 地址。该 MAC 地址与产品的硬件唯一名称相对应。它可以与人类的 DNA 相提并论。每个以太网设备都会在其发送的每条信息中插入唯一的 "MAC "地址。当收到来自特定 MAC 地址的帧时，交换机上用于该地址的端口就会被自动学习。一旦学习到地址，交换机就会只将报文路由到相应的端口，而不是像集线器那样将报文广播到所有端口。学习到新地址时，还会在内存中设置一个时间戳。该时间戳与老化功能一起使用，老化功能将在 300 秒后从表中删除未使用的 MAC 地址。如果设备移动，交换机上的相关端口将根据需要进行更改（迁移）。在大多数交换机中，可随时存储和监控多达 2048 个 MAC 地址。如果您对我们的以太网交换机和媒体转换器有任何疑问，请联系我们的技术支持团队。

Q: What are the OSI layers?

什么是 OSI 层？多年来，OSI 模型（开放系统互连模型）一直在描述网络中的信息层，尤其是底层传输机制。从上到下依次为这些层，以及这些层与您的产品设计之间的关系。以太网是物理层：第 1 层和第 2 层。TCP/IP（传输控制协议/互联网协议）是一种协议，而不是网络，使用第 3 层和第 4 层。层名称功能示例7应用数据的含义HTTP6呈现数据的构件和加密5会话特定通信路径的打开和关闭4传输错误检查TCP、UDP3网络数据路径的确定IP2数据链路数据传输、源、目的地以太网1物理电压水平、信号连接、导线或光纤RJ45、光纤与 ISO 层的比较让我们将 OSI 层与道路进行比较。第 1 层（物理层）= 道路 第 2 层（数据链路）= 源是办公室，目的地是家。MAC 地址是汽车的唯一注册号。第 3 层（网络）= 确定要走的正确道路；IP 地址是街道地址。同一地址可在多个城镇找到。第 4 层（传输）= 错误检查：目的地是否正确？ 第 5 层（会话）= 支付车费；源和目的地之间的握手 第 6 层（呈现）= 出租车是路上众多出租车中的一辆--数据流中的 1 条信息 第 7 层（应用）= 旅行的目的是什么？如果您对我们的以太网交换机和媒体转换器有任何疑问，请联系我们的技术支持团队。

The IP address (Internet Protocol) is the unique identifier of each device within a network.  The IP Address of both source and destination device is included in each IP message.  They indicate the source and the destination where IP packets shall go. An IP address consists of four bytes (for example 192.10.0.5). IP addresses are divided into two parts: <ul> <li>a network part </li> <li>a computer part</li> </ul> It may be manualy or automaticaly (DHCP) assigned by a server device such as a server, or even a managed Ethernet switch.   If you have any questions about our Ethernet Switch and Media Converter, contact our <a href="https://support.amphenol-socapex.com/hc/en-gb/requests/new" target="_blank">Technical Support team.</a> More information on <a href="https://online.flippingbook.com/view/763483120/" target="_blank">Rugged Ethernet Switch & Media Converters catalog.</a>

MAC = Media Access Control  Each Ethernet device has an assigned unique MAC address. This MAC address corresponds to the hardware unique name of the product. It may be compared with the DNA of a human.  This address is fixed during production by the manufacturer and can’t be changed. Each Ethernet device inserts its unique “MAC” address into each message it sends out. The port on the switch used for a given MAC address is automatically learned when a frame is received from that address. Once an address is learned, the switch will route messages to only the appropriate port, instead of broadcasting messages out all ports like a hub. A time stamp is also placed in memory when a new address is learned. This time stamp is used with the aging feature, which will remove unused MAC addresses from the table after 300 seconds. If a device moves, the associated port on the switch will be changed (migrated) as needed. In most switches, up to 2,048 MAC addresses can be stored and monitored at any time.   If you have any questions about our Ethernet Switch and Media Converter, contact our <a href="https://support.amphenol-socapex.com/hc/en-gb/requests/new" target="_blank">Technical Support team</a>.

An IP frame contains several information such as: <ul> <li>The destination IP and MAC address </li> <li>The source IP and MAC address The type of protocol used (TCP, UDP and others) </li> <li>The length of the message Encryption data VLAN tags and much more</li> </ul> What is Flow Control? Devices use flow control to ensure that the receiving device takes in all the data without error. If the transmitting device sends at a faster rate than the receiving device, then the receiving device will eventually have its buffer full. No further information can be taken when the buffer is full, so a flow control signal is sent to the transmitting device to temporarily stop the flow of incoming data.  For each port, Flow Control can be enabled or disabled.  Military Ethernet Switches - What is the difference between Unicast, Broadcast and Multicast messages? Broadcast messages are sent to all stations in the network.  Whereas an unicast message is only sent to one station on the network.  Multicast messages are sent to a group of stations, for example video cameras type. Using multicast allows the building of distribution networks, which are suitable for video monitoring or television transmissions over the Internet, i.e. information with one sender and many receivers.  IPv4 addresses as 255.255.255.255 or 192.168.0.255 are BROADCAST IP addresses.  IPv4 addresses from 224.0.0.0 to 239.255.255.255 are MULTICAST IP addresses.  Learn more about our Rugged Ethernet Switches by clicking <a href="https://online.flippingbook.com/view/763483120/" target="_blank">HERE</a> What means Auto-MDI/MDIX-Crossover?

The Internet Protocol Suite (commonly known as TCP/IP) is the set of communications protocols used for the Internet and other similar networks.  It is named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were the first two networking protocols defined in this standard. The TCP/IP model consists of four layers. From lowest to highest, these are the: <ul> <li>Link Layer (2) </li> <li>Internet Layer (3) </li> <li>Transport Layer (4) </li> <li>Application Layer (7) </li> </ul> If you have any questions about our Ethernet Switch and Media Converter, contact our <a href="https://support.amphenol-socapex.com/hc/en-gb/requests/new" target="_blank">Technical Support team</a>.

Our wiring harness and cable assembly facilities are located in France and India. •    In France, we have a dedicated workshop in Thyez to deliver high quality electrical harnesses. •    In India, we have over 1500 sq. meter of <a href="https://www.youtube.com/watch?v=5IAiLwO-ICM" target="_blank">cable manufacturing space in India</a> along with 12 assembly lines to design, manufacture, and install harsh environment cable assemblies.<o:p></o:p>

We have overmolding  machines at Amphenol Socapex AIMS in Pune, India. We are able to manufacture numerous connector configurations tooled up, straight or right angle versions (HE308-38999 series I plugs and receptacles, 38999 series III plugs and receptacles, 2M plugs and receptacles, PT-451 plugs and receptacles……). Our molds are developed and manufactured in-house , if you need a particular configuration, ask us. we can build a new tool within 12 weeks.

Yes, overmolded harnesses are perfectly adapted to harsh environments for military and industrial applications. Depending on customers’ requirements, we are able to perform numerous tests in our technical laboratory (pulling, bending, thermal shocks….). The only limit of overmolding technology is the repairability of the harnesses.

The Overmolding technology consists in putting the rear side of the connector/backshell together with the cable into a mold, to mold a protection around the connector/backshell and the cable. The Overmolding replaces the use of a re-glued heat-shrink molded piece. This creates a very strong and sealed junction between the connector/backshell and the cable, along with a very clean finish.  <o:p></o:p>   <article class="align-center"> <img width="275" height="245" alt="overmolding technology cordsets jumpers" loading="lazy" class="lazyload" data-src="/sites/default/files/styles/optimized/public/media/image/2023-12/overmolding_technology.jpg?itok=pLcE6oEo"> </article> <o:p></o:p> Amphenol overmolded cordset<o:p></o:p>
