With the continuous development of routing technology, dynamic routing technology is also widely used. Here we mainly introduce the development status and history of dynamic routing technology. The Internet has passed its 40-year-old birthday. Although the media is not surprised by the report, the middle-aged crisis has indeed come, one of them is one of the core technologies that have been advertised and touted as "Dynamic Routing Technology". It is the "key" for the Internet to defend against

layer traffic must be used, that is, the stateful 4 ~ Layer-7 traffic. Separate 4 ~ Layer-7 Traffic testing tools are available on the market, including IXIA IxLoad. One of these tools is to directly connect to the sending and receiving ports of the devices under test, there is no complex and real route table. In order to fully verify the performance of the routing device with the deep packet detection function, the route table and 4 ~ Layer-7 stateful traffic integration testing.The latest dev

twoA security_attributes structure and initialize them to create their own security permissions and assign them to process objects and thread objects.Another reason to use the security_attributes structure for psaprocess and Psathread parameters is that the parentAny child processes that are generated in the future can inherit any one of the two object handles. 　　 The Fdwcreate parameter is used to identify flags that are used to specify how new processes are created. 　　 The pvenvironment param

that needs to be done is to clarify the purpose of the upgrade and the customer's needs. For new features or new features To upgrade the hardware, you need to know the following requirements: Platform requirements: network devices are Cisco products, and the hardware boards to be supported are added. Protocol requirements: What protocols are required for network applications, such as TCP/IP, IPX, Or ISIS routing protocols Feature requirements: some s

The main values are bgp, eqp, igrp, isis, ospf, static [ip], connected, and rip. Process-id: the ID of the OSPF process. Metric: an optional parameter used to specify the metric value of the route for redistribution. The default measurem

When an SQL statement is executed repeatedly, You can bind parameters to improve the SQL Execution speed.Copy codeThe Code is as follows:$ Mysqli = new mysqli ("localhost", "root ","");$ Mysqli-> select_db ("mydb ");If ($ mysqli-> errno = 0) // checks whether the current connection is successful.{$ SQL = "INSERT INTO student (id, name, age, address) VALU

Multithreading ConceptsConcurrency and parallelism　In a multithreaded process of a single processor, the processor can switch execution resources between threads to perform concurrency.In the same multithreaded process within a multiprocessor environment with shared memory, each thread in a process can be in aRun concurrently on a separate processor to perform parallelism. If the number of threads in the process does not exceed the number of processors,The support system and operating environmen

Management Distance definition Management Distance in a route is a method to sort the reliability of the route selection information. The management distance is a certificate between 0 and, and the smaller the value, the higher the credibility. Although the management distance can be set to 1-9, they are reserved for internal use and are not recommended for use. The default Management distance is the default Management Distance for various routing protocols. However, you can manually modify the

. If necessary, use area X nssa default-informatin-originate to generate the routes, A 7-class LSA (routing performance is O * N2) is generated. 4. There are two default routing methods for 8 0 in China: ip route 0.0.0.0 0.0.0.0 next hop ip address, even if network 0.0.0.0 is used to advertise the default route in this way, no direct connection interface of the default route ip route 0.0.0.0 0.0.0.0 is injected to other routers. network 0.0.0.0 is used to advertise the default route in this way,

neighbors;In IS-IS, dis is not synchronized with its neighbors (synchronize ). DIS generates the pseudo-donode for the LAN and sends PSNPs (partial sequence number PDUs) every 3 seconds or sends csnp (complete sequence number PDUs) every 10 seconds ). Other routers can also use PSNPs to request a lost LSP from DIS or send a new LSP to DIS. Because DIS can flood PDUs, DIS does not need to be synchronized with its neighbors (synchronization); because it does not need to be synchronized with its n

"Agile Processes" are a collection of values and methodologies. Since 2001, some experts in the software industry have started advocating "agile" values and processes that affirm the value of popular practices, but emphasize that agile practices can bring value.Among them, extreme programming (EXtrem

Before route redistribution, you must first: 1) decide where to add a new protocol. 2) determine the border router ASBR of the autonomous system ). 3) decide which protocol is at the core and which is at the boundary. 4) determines the route redistribution direction. You can use the following command to reallocate route updates. This example is for OSPF ): Router (config-router) # redistribute protocol [process-id] [metric-value] [metric-type-value] [subnets] In this command: ◆ Protocol:

between nodes. LDP signaling and tag binding information are transmitted only between neighboring MPLS nodes. Standard routing protocols need to be run between LSR or between LSR and LER to obtain topology information. With this information, LSR can clearly select the next hop of the packet and establish a specific tag exchange path LSP ). MPLS uses the control drive model, that is, it initializes the allocation and forwarding of tag binding information used for creating LSP Based on the topolo
