The G.astn control layer is composed of the optical connection controller, which overlaps with the transmission network, and each optical connection controller corresponds to the Optera Connect network node one by one. The G.ASTN control layer provides routing and signaling transmission through optical network according to the requirements of the edge users.

Because we know that they are all numeric values can be aligned together through a consistent offset. With deep-seated, there are several compression methods that can be applied to these numbers. You may know that the above numbers are multiples of 100
management mechanism. It's easy to see that each process considers itself exclusive of the main memory. The simplest example is that a building is divided into multiple rooms, each room is independent, and the owner is exclusive, and each owner can self-decorate from scratch. In addition, You will not be able to enter other rooms without the consent of the other head of household.
The presentation of virtual memory also alters the way memory is accessed. Previous CPU accesses main memory in the

JQuery: gt selector, jQuery: gt Selector
: Gt selector definition and usage:
This selector matches all elements whose index values are greater than the given index values.
The minimum index value starts from 0.
Syntax structure:
$(":gt(index)")
This selector should also be used with other selectors, such as class selector and element selector. For example:
$("li:gt(0)").css("color","blue")
The above Code sets the font color of the li element with an index greater than 0 to green.

?? At first glance, it seems that as long as your CPU supports hyper-threading, you should select this option, but I don't think so. For example, if your system is single-CPU and supports hyper-threading, The CONFIG_SCHED_SMT macro has no significance for improving the scheduling effect (of course, if I understand the kernel scheduler correctly :)), in addition, defining the CONFIG_SCHED_SMT macro also adds additional overhead to scheduling.
