Ethernet technology for transmission. Regardless of the method chosen, the growth rate of IP services running on real Ethernet or SONET is growing rapidly. It is noteworthy that with the establishment of the 802.3AE 10G Ethernet standard, Ethernet can digest the entire OC signal for the first time without wasting bandwidth. The transfer of G-bit Ethernet on OC-48 (2.4GB/S) can be very inefficient because there is always unused bandwidth in the signal. 10G Ethernet can greatly improve transmissi

After you complete these operations, start the first User space program ( init ) and perform advanced system initialization work.This is the whole process of Linux booting. Now let's dig into the process and delve into some of the details of the Linux boot process.System bootThe system boot phase relies on booting the hardware on the Linux system. In an embedded platform, a boot environment is used when the system is power-up

On PyCon, some kids shoes share similar concepts, but it is not suitable for general Internet projects. It feels a little too different. However, I implemented this solution before seeing PyCon's sharing. The same requirement is different. Here, I only implement a data access component, not a Server. First, the method in this article is from how to use the MySQL database shared by FriendFeed. In short, the Python object is directly dumps and then zip compressed and stored in a MySQL field. Isn't

layout update, the control module updates the layout database data maintained by the interface module, and the routing determines the device to perform complex path computing for the given call request. Layout updates are usually carried out cyclically or only when major changes occur. These updates do not bring about a lot of work. In addition, the layout aggregation technology can also expand the routing protocol to a larger network. In this system structure, the control module no longer proc

In addition to FCIP, another method is iSCSI, which converts user requests into SCSI code and encapsulates data into the IP package for transmission over Ethernet. To connect a geographically dispersed SAN, the FCIP Protocol can only be used for Fiber Channel Technology connections. In contrast, iSCSI can run on an existing Ethernet. SAN connections, such as FCIP and iSCSI protocols, can provide higher performance, validity, and fault tolerance based on point-to-point connections of traditional
