摘要語內翻譯不是簡單的同一語言內部的語碼轉換過程，而是在同一語境內部，在保持一定時空距離的條件下，譯者對原作做出的新的解釋，並且是在對傳統繼承基礎上的新的發展。 -
Based on the mfc ( multicast forwarding cache ) formed by multicast protocol such as dvmrp ( distance vector multicast routing protocol ), pim ( protocol independent multicast ), we can build special lsp ( lable switch path ) for certain source group couple to transport multicast data flow using ldp ( lable distribute protocol ) or cr - ldp. based on the zxb10 switching router of zte co. we can now support dvmrp within the context of mpls networks
本文主要研究mpls網路對ip組播業務的支持，根據現有的ip組播協議如dvmrp 、 pim等所生成的組播轉發表（轉發樹） ，利用mpls網路的ldp （標記分發協議） cr - ldp （顯式路由標記分發協議）為特定的源組對確立lsp （標記交換路徑） 。 -
When excessive context switching is present, lightweight pooling can provide better throughput by performing the context switching inline, thus helping to reduce user kernel ring transitions
如果出現過多的上下文切換，輕型池可以通過上下文切換內聯化，從而降低用戶/內核環的轉換頻率，達到提高吞吐量的目的。 -
This restriction on number of processes in the x86 architecture was a component of linux 2. 2, but since kernel 2. 4, this problem has been eliminated, partly by doing away with hardware context switching which made using tss inevitable and replacing it with process switching
這種x86架構中進程數量的限制是linux 2 . 2中的一個組件，但自2 . 4版的內核開始，這個問題已經不存在了，部分原因是使用了硬體上下文切換（這不可避免地要使用tss ） ，並將其替換為進程切換。 -
In this chapter, it puts forward a new system about checkpoint, avoiding the domino - effect and livelock. it realizes the storage of process context and other states with the form of executing file in the diskette by using checkpoint system and applying the page switching principles in linux. consequently, when the process has wrong at the checkpoint, it can move out the process in the fault machine, then choose other normal machine, continue to execute from the interrupted point, finally achieve the process migration and load balance of the system
同時提出一種新的檢查點機制，避免了多米諾效應和活鎖，並且利用檢查點機制，應用linux中頁面的換出原理，實現了對進程的上下文以及其他狀態以可執行文件格式保存在磁盤，從而使該進程能在節點發生故障的情況下，將故障機的進程遷出，然後選擇其他正常節點機，從斷點處繼續運行，最終達到對該進程的遷移，並且實現系統負載平衡。 -
Modern operating systems generally do an excellent job of process scheduling, which minimizes context switching
現代操作系統通常在進程調度方面表現得很出色，從而最大程度減少了上下文切換。 -
Context switching occurs when the operating system scheduler replaces one process operating on a cpu with another process and is the result of a variety of factors, such as job or process priority, waiting for other resources like i o, if the process is using up all of its allocated cpu cycles time slice, and so on
上下文切換是在操作系統調度程序用另一個進程替換cpu上正在運行的一個進程時發生的，而且是各種因素作用的結果，例如作業（或進程）優先級、是否等待其他資源（如i / o ） 、進程是否將用完所有分配給它的cpu周期（時間片）等。 -
Assigning processors to specific threads can improve performance under these conditions by eliminating processor reloads and reducing thread migration across processors thereby reducing context switching ; such an association between a thread and a processor is called processor affinity
如果將各個處理器分配給特定線程，則通過消除處理器的重新加載需要以及減少處理器之間的線程遷移（因而減少上下文切換） ，可以提高在這些條件下的性能；線程與處理器之間的這種關聯稱為「處理器關聯」 。 -
Understanding context switching
了解上下文切換 -
This credential handle can now be passed around to the other functions in this list so that switching user context via seckfmswitchtoidfile is not necessary
該憑證句柄可以傳遞給這里列出的其他函數，所以就不再需要通過seckfmswitchtoidfile來切換用戶上下文了。 -
Switching context between users for example, switching from admin - user to another user, and then back multiple times has performance implications
在用戶間進行多次上下文切換例如，從admin用戶切換到另一個用戶，然後又切換回來會帶來性能隱患。 -
On the analysis of the existing content - based request redistribution ( layer - 7 switching ) methods, we propose the method of using kernel thread to implement content - based request redistribution inside the operating system, which can avoid the overhead of context switching and memory copy between the kernel and user space
在對已有基於內容請求分發（ layer - 7交換）的方法進行分析基礎上，本文提出在操作系統中利用內核線程高效地實現基於內容請求分發的解決方法，避免多次內核與用戶空間的切換和內存復制開銷。 -
The connection concentrator is associated with context switching of agents
連接集中器與代理的上下文切換相關聯。 -
Context switching permissions
上下文切換權限 -
Context switching between threads involves saving and restoring the state of threads
上下文的切換包括了保存和恢復線程狀態。 -
Tss holds hardware context information for each cpu which helps to take effect in context switching
Tss中保存了每個cpu的硬體上下文信息，它有助於有效地切換上下文。
