the private network signaling or data. This means that, for example, at night, there is no voice traffic, and billing can be transmitted using the vast majority of bandwidth. The problem of frame mode reuse is the delay and how to manage the priority of traffic, to overcome these problems, advanced switching nodes can take the following measures: Data frame segmentation, user data frame may be very long, when there is a very long frame to send, in order to avoid long delay, the long frame is d

best choice. The hardware that determines whether the PC can output 4K resolution is the video card, currently only Kepler architecture, GCN architecture, or the stand-alone graphics that update the architecture support output 4K resolution, the set platform aspect will use Haswell architecture processor or Kaveri APU side can support. First, let's look at how the set up platform outputs the 4K resolution, and the Intel platform must be equipped with the HD Graphics 4200/

technology is very general, performance promotion is very limited, and desktop dual-card fire is not comparable. Since only changed the name of the exchange of fire, and the principle of the exchange of fire does not really change, so for the new Kaveri Apu Crossfire, I still do not optimistic.
