BackgroundWe need simple access to XML to parse XML documents. So you just have to know where the results are in the XML document code and then parse it. For example, in the following picture, we want to know about the weather in Sfax, Tunisia:
In the beginning, we need to specify the city or state where we want to know the weather.
The code is as follows
Copy Code
String C = City.gettext (). toString ();String s = State.gettext (). toString ();StringBuilder URL

FIRST,SJF/SPF) scheduling algorithm is based on the CPU time required by the process, and always selects the process with the shortest estimated calculation time to run. The shortest process priority scheduling algorithm is the best local method, which satisfies the requirement of the shortest average waiting time. However, it is difficult to implement SJF scheduling because it is difficult to predict the length of the next CPU demand interval for th

WAN Port defaults to 64,OSPF default value of 100 divided by the interface bandwidth 1.544=64 can go to show interface query, router source interface to other networks, is to take the cost value of the interface as the path orientation. For example: R3 s1/0 and S1/1 if s1/0 does not manually specify the cost value. The default is 64. Then R3 to the other route does not take s1/0 this interface.
Third, through the common sense analysis router's cost is smallest, should take 2 this road to go,

When you use the SAX API, all input starts with the Org.xml.sax.InputSource class. This class is contained in the SAX API and provides input specifications (through standard Java constructs similar to file or I/O streams) and also provides a common system identity. Then, SAX extracts this information from the InputSource when parsing, allowing it to resolve external entities and other source-specific resources.

First, the OSPF characteristics:
1.IETF Standard: Open room agreement, supported by different manufacturer's equipment
2. No loop by protocol: the implementation of SPF algorithm, will not produce loops
3. No class routing protocol: Support for VLSM and CIDR
4. Have unrestricted hop count: can be applied with large network
5. Level: Easy to expand, router burden will not increase with the size of the network increased dramatically

, when invoking the method of the event handler, passes the contents of the current parsed XML file to the event handler as a parameter to the method.
The event handler is written by the programmer, and the programmer can easily get the data parsed by the SAX parser through the parameters of the method in the event handler so that it can decide how to process the data.

2) State
Technical principle:
OSPD Open Shortest Path priority protocol. is one of the most widely used routing protocols in the current network. belongs to the internal network routing protocol. Being able to adapt to network environments of all sizes is a typical link-state protocol. The OSPF routing protocol spreads the link state information of the device to the whole network, so that each device in the net finally synchronizes a database with the whole network link state, then the router uses the
protocol, once the link fails and then resumes, SPF recalculates all the topologies in the zone and synchronizes it to each router, during which time the synchronization topology makes the device a lot worse, and the CPU utilization runs to 80%. The topology stabilizes to normal forwarding, This is only IGP, and this problem is even more serious in Mpls te, because after IGP is stable, LDP or RSVP can work, build up and then distribute tags to create
