The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for cascading purposes. Analysis of the switch fiber port Cascade connection mode and basic types, welcome to add message. Cascading can use either a normal port or a special mdi-ii port. A pass-through cable should be used when the two ports that are cascaded are normal (

the same location is expensive, and often leads to network internal blocking. In the future, in order to better support VoIP, IPTV and other real-time IP services, also requires data network to improve business quality. Considering that the same I/O port core routers have a market price of 5 times times the SDH device, it is recommended to use a light crossover machine to transfer IP direct service to improve efficiency, while IP routers focus on 3-

local optimal solution can jump out of probability and finally tend to the global optimal. The key of the simulated annealing algorithm is to control the temperature (probability) to reduce the speed of the parameter R, this parameter range is 0 The simulated annealing algorithm can not guarantee the real optimal solution, but the optimal solution with high quality is obtained under the condition of good efficiency. Genetic algorithm Genetic algorithm is a kind of evolutionary algorithm, whic

nodes in the path. 2. Randomly select 2 nodes to reverse the node order between the 2 nodes in the path. 3. Randomly select 3 nodes m,n,k, and then shift the node m and n between nodes to node K. "Algorithm Evaluation" Simulated annealing algorithm is a kind of stochastic algorithm, and it is not always possible to find the global optimal solution, and it can find the approximate optimal solution of the problem fairly quickly. If the parameters are set properly, the simulated annealing algorit

protocols such as PPTP (Point-to-Point Tunneling Protocol). Once the routing lookup is complete, the packet must be sent to its output port with a switching switch. If the router is an input-side plus queue, there are several inputs that share the same switch. The final function of this input port is to participate in the arbitration agreement for public resources such as switching switches. Switching switches can be implemented using a variety of different techniques. The switch technology th

need to transfer data through a hub or vswitch. However, when connecting two NICs, you cannot directly use the express Connect line, but you must use the cross-type network line. When creating a cross-type network line, you must use the T568A line sequence to connect one end to the other, the other end uses the T568B line sequence connection. If the crossover network cable is not created in accordance with such standards, even if the two computers ca

will continuously generate a golden crossover or death crossover. Among them, some gold cross has the bottom significance, and some death cross has the top significance. A large number of intersections can only be the middle of stock price changes. To find out the gold crossover with a bottom significance or the dead crossov
