1. DX Connection 创建演示
时间范围：00:00–00:15
总结 / Summary
中文
本讲通过 AWS 管理控制台（AWS Management Console）演示如何创建专用 Direct Connect 连接（Dedicated Direct Connect Connection）。
English
This lecture walks through creating a Dedicated Direct Connect Connection in the AWS Management Console.
Transcript
00:00 Hello and welcome to this lecture.
00:01 So in this lecture, let me quickly walk you through the steps
00:05 on AWS console to create Dedicated DirectConnect connection.
00:10 And this is really, really very simple. So it must be very quick.
00:14 Now,
2. 进入 Direct Connect Connections
时间范围：00:15–00:26
总结 / Summary
中文
在 AWS 控制台打开 Direct Connect 服务，进入 Connections 页面并选择 Create connection。
English
Open the Direct Connect service, go to Connections, and choose Create connection.
Transcript
00:15 what you need to do is to just go to
00:17 your AWS console and go to DirectConnect AS a service.
00:20 Once you are in the service, go to the connection
00:22 and directly, you can go and say create a connection.
3. 选择创建方式
时间范围：00:26–00:44
总结 / Summary
中文
创建页提供经典模式（Classic）和连接向导（Connection wizard）；向导适合跨多个 DX 位置构建弹性连接（resilient connection）。
English
The page offers Classic and Connection wizard; the wizard is useful for resilient designs across multiple DX locations.
Transcript
00:26 Now, here there are two options, classic and connection wizard.
00:29 The connection wizard is more important when you have to have, you have to create
00:34 a resilient connection where it allows you to
00:36 create multiple connections at multiple DX locations.
00:39 And we will talk more about that,
00:41 when we talk about High-Availability of direct connect connections.
4. 使用 Classic 模式
时间范围：00:44–00:51
总结 / Summary
中文
演示选择经典模式（Classic），用于创建单个、直接配置的 Dedicated Connection。
English
The walkthrough selects Classic for a single, directly configured Dedicated Connection.
Transcript
00:44 But let's go with the simple connection, which is a classic.
00:48 Of course, we need to give some name. So
5. 填写连接名称
时间范围：00:51–01:00
总结 / Summary
中文
为连接填写可识别的名称，然后继续选择 Direct Connect 位置（DX location）。
English
Enter a recognizable connection name, then select the Direct Connect location.
Transcript
00:51 my first DX connection
00:55 and then you have to select the location.
00:58 Now it will show you the location across the globe.
6. 全局 DX 位置列表
时间范围：01:00–01:11
总结 / Summary
中文
Direct Connect 控制台是全局服务界面，位置下拉框会列出全球各区域的 Direct Connect 位置（DX locations），而不是限定在当前区域（Region）。
English
Direct Connect uses a global console, so the selector lists DX locations worldwide instead of limiting choices to a current Region.
Transcript
01:00 Now understand that the direct console is the Global one.
01:04 There is no Region here and you will see all the
01:07 regional direct connect locations right here in this dropdown.
7. 选择 Mumbai 位置
时间范围：01:11–01:19
总结 / Summary
中文
在位置列表中搜索 Mumbai，并选择 GPX Mumbai, India 作为物理接入点。
English
Search the location list for Mumbai and select GPX Mumbai, India as the physical access site.
Transcript
01:11 So maybe if you want to select something from Mumbai,
01:13 I will see what all options are there.
01:16 And maybe let me select GPX Mumbai India.
8. 选择端口速度
时间范围：01:19–01:39
总结 / Summary
中文
可选端口速度（port speed）取决于 DX 位置；GPX Mumbai 提供 1 Gbps 和 10 Gbps，而部分位置还支持 100 Gbps。
English
Available port speeds depend on the DX location; GPX Mumbai offers 1 and 10 Gbps, while some sites also support 100 Gbps.
Transcript
01:19 Now as per the DirectConnect location, it will give you option for the posts speed
01:23 1 Gbps, 10 Gbps or
01:26 in certain cases where 100 Gbps link is supported, you will also get that option. But
01:32 at Mumbai GPX I only have option for 1 and 10 Gbps.
01:36 So I can select one of them.
01:38 And
9. 是否需要 DX Partner
时间范围：01:39–02:01
总结 / Summary
中文
若客户在 DX 位置没有路由器，可请求 Direct Connect 合作伙伴（DX Partner）提供设备和交付支持；已有现场设备时可取消该选项。
English
Customers without a router at the DX location can request DX Partner assistance; customers with an existing presence can clear the option.
Transcript
01:39 if I don't have my router already in the DirectConnect location,
01:43 then I can
01:44 also asked to connect me with the DirectConnect
01:47 partner so that I can get that router.
01:49 Now, if you already have your presence in that location,
01:52 then you just unselect that and you don't need to select that partner
01:56 and that's it. And
01:58 you have to just create the connection.
02:00 Now,
10. MACsec 可用性
时间范围：02:01–02:19
总结 / Summary
中文
MACsec（Media Access Control Security）可在二层加密 Direct Connect 流量，但支持情况取决于具体 DX 位置；本例位置不可用。
English
MACsec encrypts Direct Connect traffic at Layer 2, but availability is location-specific and is not supported at this example site.
Transcript
02:01 there is something called MACSec security, which we will talk again later.
02:04 But again, this is very specific to the direct connect location.
02:07 It is not available at all the locations.
02:10 And ultimately, what it does is, it encrypts your direct connect traffic as well.
02:14 But for Mumbai, this location, it is not applicable. So I'm not doing anything
11. 提交连接请求
时间范围：02:19–02:21
总结 / Summary
中文
确认名称、位置、端口速度和合作伙伴选项后，选择 Create connection 提交 Dedicated Connection 请求。
English
After confirming the name, location, port speed, and partner option, choose Create connection to submit the request.
Transcript
02:19 and I'll just go and create the connection.
12. Requested 到 Pending
时间范围：02:21–02:37
总结 / Summary
中文
新连接首先显示 Requested，随后转为 Pending，表示 AWS 正在执行网络和端口配置。
English
The new connection moves from Requested to Pending while AWS provisions the network and port.
Transcript
02:21 So now you can see that the status of this connection went from
02:26 requested to the pending. And
02:28 so I'm just pausing this video for a couple of seconds
02:31 and I'll show you the new status of this connection.
13. 连接状态变为 Down
时间范围：02:37–02:44
总结 / Summary
中文
状态变为 Down 表示 AWS 侧网络资源已经建立，但物理交叉连接（cross-connect）尚未提供链路信号。
English
A Down state means AWS-side network provisioning is complete, but the physical cross-connect is not yet carrying signal.
Transcript
02:37 Ok. So now you can see that the connection has turned to be down. That means
02:42 the network set up at least has been done.
14. 查看连接与 LOA
时间范围：02:44–03:16
总结 / Summary
中文
连接详情显示位置、端口速度、AWS 设备和授权书（Letter of Authorization, LOA）状态；LOA 签发后应交给设施运营商或 DX Partner 以完成 cross-connect。
English
Connection details show the location, port speed, AWS device, and LOA status; after issuance, the LOA goes to the facility operator or DX Partner for the cross-connect.
Transcript
02:44 And you can see the details of this connection.
02:47 You can see that state is down the location.
02:50 The AWS device has been identified, the LOA is yet to be issued.
02:55 but then once it is issued, you can download the copy of LOA
02:59 and then you can give it to your direct connect location provider to make the cross
03:03 connect as well as if you don't have your router.
03:05 You can also provide that copy to your DX partner and then partner
03:09 will provision in the router for you and then we will also issue a cross
03:13 connect request on behalf of you.
03:15 So
03:16 in general,
15. Dedicated 创建流程回顾
时间范围：03:16–03:26
总结 / Summary
中文
总体流程是创建请求、等待 AWS 配置、下载 LOA，并由设施运营商或 DX Partner 完成现场交叉连接（cross-connect）。
English
The overall process is to submit the request, wait for AWS provisioning, download the LOA, and have the facility operator or DX Partner complete the cross-connect.
Transcript
03:16 those are the steps for setting up the Dedicated direct connect connection.
03:21 So I hope that is clear. And now let's get to the next lecture.
03:25 Thank you.
整讲总结 / Overall Summary
中文
创建 Dedicated Direct Connect Connection 时，在全局 Direct Connect 控制台选择 Classic 或 Connection wizard，填写名称、DX location 和 port speed，并决定是否需要 DX Partner。提交后连接从 Requested/Pending 进入 Down，AWS 签发 LOA 后由设施或 Partner 完成 cross-connect；MACsec 是否可用取决于具体位置。
English
To create a Dedicated Direct Connect Connection, choose Classic or Connection wizard in the global Direct Connect console, enter the name, DX location, and port speed, and decide whether DX Partner assistance is needed. After submission, the connection progresses through Requested/Pending to Down; once AWS issues the LOA, the facility or partner completes the cross-connect. MACsec support is location-specific.
