Brief Introduction to the link status Routing Protocol: the link status routing protocol is just like using a map. With a map, you can see all the potential paths and determine your preferred path. The status of a link refers to the status of the network directly connected to the vro and contains information about the network type and all the routers adjacent to the vro. Therefore, the link status routing protocol is named.Link Status Routing Protocol: This is also called the Shortest Path prior
In Java programming, we often use XML to store data. To obtain data in XML, We need to parse XML. The following is an example of using Sax to parse XML,
General steps:
1. Create a saxparserfactory object; saxparserfactory SPF = saxparserfactory. newinstance ();
2. Use the factory object created above to create a saxparser resolution object; saxparser sp = SPF. newsaxparser ();
3. Create a saxhandler process
charges.
The reverse parsing process can be simulated in Windows as follows:
Command line:NSLookup-Qt = PTR
Enter the IP address you want to query, as shown below:
> 208.50.56.68
Non-authoritative response:
68.56.50.208.in-ADDR. ARPAName = mta406.us.news.gaopeng.com
What is an SPF record?:
The full name Is Sender Policy Framework, which is the sender's policy architecture. It is usually called SPF
1) is-is only defines two network topology types: Broadcast and point to point. In a Cisco router, links are divided into point-to-point and broadcast.
Opsf defines five network types: point-to-point, point-to-multipoint, broadcast, point-to-multipoint nbma and nbma.
2) both Protocols maintain a link state database)
Is-Is uses LSP (link state PDU). LSP itself is a datagram, two-layer data frame;
When OSPF uses LSA (link state advertisements), lsa must be encapsulated in the OSPF header and IP he

Technology and yahoo's DomainKeys technology, and these two technical ideas are also very close.
The Sender ID uses DNS extension to verify whether the Sender actually comes from the domain it claims. The workflow is as follows:
The preceding process is the same as the START process. User a (Sender) sends itB @domain-b.comTo the smtp.domain-a.com. The smtp.domain-a.com claims that the sender is a user of the domain-a.com domain, sends the mail to the mx.domain-b.com (inbound e-mail server), and

Inter-domain traffic (inter-area traffic): refers to traffic that is composed of packets exchanged between routers in different regions.? external traffic (External traffic): refers to traffic that is made up of packets exchanged between routers in the OSPF area and routers outside the OSPF area or in another autonomous system.The ability of OSPF to be partitioned into multiple reg
For anti-spam, it is best to configure two DNS records under the domain name used by the sender: SPF and DKIM, they are used for anti-spam, the Mail accepts the server will check these two items, only meet the requirements to enter the user's mailbox.In general, we use third-party mail services such as SendGrid, Postmarkapp, etc. when sending large quantities of mail, and they will give you the value of these two records,dealer, add these two records

The internet has been used in a wide range of applications, even in advertising, which is thought to belong to the creative industry.In the United States, the traditional advertising internet-based agent business has begun to do a great deal, and the traditional advertising agent has a huge impact. In search giant Google, for example, to expand its online advertising business, as early as January 2006, Google bought online link advertising and wireless radio company
