With the continuous development of wireless networks, multi-Stream Aggregation (MSA, Multiple Stream Aggregation) can improve the edge throughput by 500% through deep fusion of Multi-standard, multi-carrier and multi-layer networks, realizing the concept of borderless networks enables users to enjoy high-speed and stable data access services wherever they are on the network. It will become a key technology for network evolution in the future. The popu

What is micro-service architecture From the industry's discussion, the microservices themselves do not have a strict definition. However, the description of ThoughtWorks's chief scientist, Martin Flowler, is more understandable: A microservices

gradually increase the complexity after the test is successful. After each test is completed, the test result should be edited into a document and checked against the project requirements. Investigate and solve any problems. To achieve its testing objectives, the MSM testing team has constructed an integrated testing environment for the integration test of the MSM solution. The design of this test lab should be as similar to the actual production environment as possible. The MSM solution was

There are many packages under Linux that can implement standard mail services. Unix/linux e-mail system model can be divided into the mail delivery Agent MTA, mail storage and acquisition agent MSA, and mail client Agent MUA three modules. Although there are some special mail applications that cannot be classified exactly as described above. Here's a brief overview of Linux mail services. 1, mail delivery agent-mta The mail delivery agent under Linux

Rsp_k23 messages include MSH, MSA, err, qak, qpd, and PID segments. Err and PID are optional.1. When the MSA has an err, the err segment is filled with detailed information about the error. 2. when MSA is AA and qak is OK, PID is not empty; otherwise, PID should be empty 3. when the MSA has an err, The qak's response s

When you deploy AD RMS today, you need to create a separate service account for RMS, so you associate a new feature in Server 2008 R2: Managed service account. First, let's find out what it is, right? Managed Service account: Due to the cumbersome management of the domain user account password for the service being run, the hosting service account (Managed) has emerged. The so-called Managed services account, which is entrusted to the operating system to manage the account number. The password

If either MSA is installed, use the Uninstall-adserviceaccount cmdlet to remove the locally installed service account. After you complete the operation to take the source domain controller offline in step 6th, you can use Install-adserviceaccount to re-add the MSA when t

The composition of the e-mail system:1) Mail user agent (Mailuseragent,mua), MUA is a mail system client program that provides a user interface for reading, sending, and receiving e-mails. Most commonly used MUA has:linux mail,elm,pine and so on. Windows outlook,foxmail et 2) mail agent (mailtransferagent ,MTA) MTA responsible for the storage and forwarding of messages (storeandforward). MTA Monitor the user agent's request, locate the corresponding mail server based on the destination address

Enterprise Open Source Email system Introduction Enterprise Open source e-mail system model can be divided into the mail delivery agent MTA, mail storage and acquisition agent MSA and mail client Agent MUA three modules, the following on the composition of the mail system introduced. Message Delivery Agent (MTA) The Mail-delivery agent (mail Transfer agent) under the Enterprise Linux open source system usually uses Sendmail, which has a correspondi

Three Google TPU2 cabinets Google shows the top view of the TPU2 circuit board and the proximity of the front panel interface of the circuit board. All 4 quadrants of the TPU2 circuit board share the same power distribution system. We believe that the 4 TPU2 circuit board quadrants also share the same network connection through a simple network switch. It seems that each circuit boa

When checking the security log, we found that there were a bunch of IP addresses every day to guess the password over the past few days. It seems that it is better to change the logon authentication method to certificate authentication. In case of protection, a VNC is enabled temporarily, so that sshd cannot be restarted without configuration. (Later I found it redundant, as long as I open a putty fi

reduce the implementation cost of 50g. For example, if the cost structure of 25g cabling is the same as that of 10g cabling, the performance is 2.5 times. Similarly, the cost of 50 GB is half the cost of 40 GB, but the performance can be improved by 25%. 100 GB For long-distance carrier networks ranging from several hundred kilometers to tens of thousands of kilometers, the deployment of G Ethernet will continue to grow.

meet high-speed bandwidth needs, such as 10 GB Ethernet and 16 GB optical fiber channels. The industry is upgrading the OM3 and OM4 light green optical fiber cables to 50 micron for long-distance connections. OM4 is ideal for horizontal cabling and inter-IDC cabling, whether for Ethernet or fiber channel. "If you are using multimode optical fiber, you should purchase OM4," Martin said. "The reason why OM4 is recommended is that it can be used for both 40g and G Ethernet, but also for high-spe
