Font Size:SmallMediumLarge|PrintRelease: Author: webmaster Source:Network reposted: 78 timesThe emergence of Softswitch technology has led to the adoption of Softswitch technology for the integration of core control layers. However, due to the large differences in fixed and mobile Softswitch functions and protocols, Softswitch has become the focus of control layer integration.

As the only routing protocol of the backbone network, ISIS has a high convergence speed. The common IGP route convergence method is to use HELLO packets to detect link failure and periodically transmit LSA (spread to neighbors when the entire LSA is received ). Therefore, when the network scale is expanded, LSDB increases, and the SPF computing time will be quite long. To improve the calculation method, we
Looking back at the construction process of the existing communication network, we can see that in the process of developing new services based on the circuit switching network, domestic operators basically adopt the method of carrying a certain type of services with a specific service network. In this way, on the one hand, the network construction cost is basically similar to that of the circuit switching network, and there is no obvious advantage. In addition, because different networks adopt
1. Introduction
As China becomes more open to the communication field, competition among telecom operators is becoming increasingly fierce. How to reduce network construction investment and reduce O M costs becomes more and more important. Network convergence enables operators to provide various fixed and mobile access services on the same network. By sharing devices in the network, carriers can achieve unified services, management, and billing, ulti

In the second phase of construction, the backbone of the use of Gigabit Ethernet technology, in order to protect the campus network Phase I Project investment, the original ATM and Gigabit Ethernet interface between the following several ways: (learning compu

Yesterday, surprised to hear Baidu update, alone in accordance with the wind in Baidu search this site keyword "Beijing website optimization", found that several main keywords have a sign back, no way, due to the recent time a little busy, did not update the site, so that the site ranked backward. Daily worry, the bitter experience of the future where, hehe. The following alone in accordance with the
If there is no port aggregation on the switch. Your two computers are connected by two wires. is a loop, and it affects both the switch and the connected computer. Therefore, the port aggregation function is very important for the Internet Café switch.
Provides a brief overview of the management switch port aggregation capabilities.

is to bind multiple physical ports (typically 2-8) to a logical channel, making them work li

STP establishes a root node, called the root bridge, and constructs a topology in which each node in the network can arrive at only one path, the final generated tree originated from the root node. redundant links that are not part of the shortest path tree will be blocked because such paths are blocked, therefore, it is possible to implement a non-loop topology. When a data frame is received on the blocked li

Canonical has been discussing convergence (fusion) for some time. The next version will try its best to be close to convergence. This will be the first operating system that can be established in both PC and mobile systems. A single program can run on different system

In the previous article, we introduced the gradient descent algorithm and used the above example of x ^ 2 + y ^ 2 to solve the problem. The Code is as follows:
Function [] = gradient (step, threadhold) % here, we mainly demonstrate how to set the initial values of X and Y by using the gradient descent algorithm % for Z = x ^ 2 + y ^ 2.% x = 100; y = 100; % calculate the value of the first two steps last_step_result = x * x + y * Y; X = x-step * 2 * X; y = Y-step * 2 * Y; this_step_result = x ^
Open Class at MIT [Introduction to Computer science and programming Using Python] 6.00.1x, Eric Grimson has mentioned that the idea of iterative algorithms is to move the current iteration point in the correct direction to a certain "step", and then verify whether the target value meets certain requirements. At the same time, "direction" and "step size" are the main concerns of different optimization algorithms two aspects. In addition, we also care about the
, then the Newton method reaches the minimum point in one step.
2. The algebraic meaning of Newton's Law
The gradient and black plug matrices are represented by the following symbols, respectively:
Set any point to Xk, the next iteration point bit Xk+sk, the Taylor expansion at Xk at the iteration point:
Replace the value of pity Dorado with the value of the next iteration point, that is:
So:
Therefore, the iteration direction is:
This direction is also known as Newton's direction.
