Frame-Rekay ): Frame relay is a connection-oriented service. It is an industry standard pure L2 data link layer protocol. It uses HDLC encapsulation between connected devices and can process multiple virtual circuits (VC; frame Relay is more effective than X.25. Currently, it is generally considered that frame relay sh

Just from the forum to see someone asked GSM time slot, channel, burst sequence, frame knowledge. Today we digital communication right up to this piece, I based on what I know and online search answer!1, Time Division multiplexing technologyFDMA: Frequency division Multiple Access TDMA: Time division Multiple Access CDMA: Code Division Multiple access in order to improve the utilization of the communication channel, so that a number of independent sig

Frame Relay is a connection-oriented two-layer packet switching technology, the core idea is to use a unique DLCI (link identifier) number to build a virtual channel to the destination, when the packet is forwarded, through the DLCI to select the path. It is a network technology that differs from the two layer Mac switching technology and the three layer IP routing technology.Three basic terms:PVC: Permanent virtual link, virtual link is established p

Foreword: In the development of iOS often encounter two words frame and bounds, this article mainly elaborated frame and bound difference, especially bound very around, difficult to understand.First, take a look at the accepted information: first see the following code you must understand some:-(CGRect) frame{ return CGRectMake (Self.frame.origin.x,self.frame.

congestion problems, and reduce Frame loss .) 1. Ethernet traffic control technology The data link layer is divided into Logical Link Control Sub-layer, MAC control sub-layer, and Media Access Control (MAC) Sub-layer. The MAC control sub-layer is an optional sub-layer, which specifies a universal full-duplex traffic control structure framework. The carrier listens for Multi-Channel Access/conflict detection (CSMA/CD) the algorithm implements half-du

Use a cisco router to simulate how to configure a frame relay switch (configure 3640 as a frame relay switch): 3640 (config) # frame-relay switching ---------------------- enable the frame relay switching function of the router 3640 (config) # int s0/0 ------------------------------------- enter the s0/0 interface 3640

Stack frame is a data structure that supports the method invocation and method execution of a virtual machine, which is the stack element of the virtual machine stack of the data area when the VM is running. The stack frame stores information such as the local variable table of the method, the operand stack, the dynamic connection, and the method return address. The first method, from the start of the call

A frame relay switch is a useful device, either in the lab or elsewhere. Like the boot register, the setting of the frame relay switch is also very profound in the router settings. You can build many different network models by learning how to configure a frame relay switch. As we are a "service provider", we must be able to independently allocate the full-induce

Bounds coordinates: Custom coordinate system. setbound specifies the coordinates in the upper-left corner of this view in this coordinate system, Default Value (0, 0) Frame coordinate: coordinates in the upper left corner of the Child view in the parent view coordinate system (bounds coordinate system). The default value is (0, 0) Actual position of the Child view = actual position of the parent view-bounds coordinates of the parent view +

Flash works in the preset frame rate is only idealized, but the reality is that flash processing programs or rendering the image needs to consume a certain amount of time, so the animation run at the frame rate of each frame is basically different. Put too many symbols in a frame, the

Frame switching is the exchange technology used by frame relay, while cell switching is the exchange technology of ATM. They all belong to the fast group switching technology. The main difference is that the frame length of the former is variable, the frame cell length of the latter is fixed. For example, if the fixed
