-base stations have also accelerated the deployment of IPv6 in China.
For equipment suppliers, they need to develop new devices with more abundant resources and comprehensive IPv6 functions.
Synchronization and IEEE 1588
IEEE 1588 and synchronous Ethernet are two important synchronization technologies used for mobile backhaul. Synchronous Ethernet is used for frequency synchronization, while

The maintenance of the release version of Major is demonstrated through a series of minor versions, mainly to fix some serious problems or security issues that lead to crash, such as major release version go 1.6 now has go 1.6.1 and go 1.6.22 subsequent minor releases.
When developing the next version of the launch plan, it is common for Russ Cox to initiate discussions at Golang-dev Group, and other core developer discuss what they are going to do in the
that inherits from the (earlier) C language implementation. All code is written based on it, so the first thing a GC package must do is convert the syntax tree of the syntax package (definition) to the compiler's AST notation. This additional step may be refactored in the future.
The AST is then checked for type. The first step is name resolution and type inference, which determine which object belongs to which identifier, and what type each expression has. Type checking includes specific addit

SSA Overview
The SSA was introduced in Go1.7, which greatly improved the performance of the compiler, but it also caused some slowdown in the compilation process. Here is a brief description of the SSA and SSA applications, combined with

Article, where the information may have evolved or changed.
The recently released Go 1.7 uses a new SSA-based compiled backend (currently only available in AMD64). The SSA makes the compiled code more efficient SSA, which consists mainly of BCE and common sub-expression elimination.
This article will show you some examples of how BCE works
Node page lock_page First is to change the state of the page: Set_page_dirty, as well as Set_nid operation will also set the parent node Nid, but this setting node-page granularity is not too small!Node_page first does not have the user-state process to operate it, because node is transparent to the user state, so the Lock_page Node page processing race condition is:Node is divided into two categories: Dnode and Indirect node, and for Dnode, the GC and f2fs_write_data_page that need to be proces
reason is "the memory used by the string was freed by SSA compilation", was recycled by GC and returned toWindows operating system. Therefore, the principle of the SSA compiler is consulted. The SSA compiler is found to be much smarter, and it can be quickly judged based on (established rules) that memory is no longer being used, so memory recovery is very rapid
. For example, the forward forwarding between two PW networks is not allowed in a mesh network. In addition, forwarding from one user port group to another user port group is not allowed. This forward forwarding rule based on PW or port is the basis of horizontal segmentation.

This is due to the time required to cache, analyze, and route data packets to many destinations. This change greatly reduces the accuracy of Clock Synchronization by 1588, thus significantly degrading the real-time control performance of the entire system. The measurement of the latency between the 1588 master and slave clock also relies on th
