Routing Simulation System Design (1) Interface Description Part 2004-3-21
1. All global variables and functions in the global name spatial routing system are implemented in a namespace.
NetSource Name Space Internal Variable: #define Null 0 // Network Device Type Table ENUM NETELEMENTTYPE {Fiber = 1, Centralrout}; // Route IP Address Length const IP_address_length = 32; // Routing Table Maximum length const INT MAX_ROUT_TABLE_SIZE = 100; // Router port largest data package capacity const INT MAX_DATA_QUE_LENGTH = 20; Name Space Function: // Determine whether two IP addresses are equal BOOL AddRequal (const unsigned int * addr1, const unsigned int * addr2);
Second, class design routing simulation system class according to the predetermined document class diagram design. The constructor of all classes is omitted with the description function interface.
1, network element class name: NETELEMENT class Nature: Pure Virtual Class Parental Class: Uncalar Primary Attribute: // Network Device Type NetlementType NetlementType; Class's primary interface: // Get the type of network device < Public> Virtual NetlementType GetType (Void) = 0;
2, network cable class name: the nature of the Absline class: Pure vain category parent class: The main attribute of the public inherits the NetElement class: inheritance attributes;
// The length of the network line int LENGTH; the primary interface of the class: virtual void setlength (int _length) = 0; virtual int getLength (void) = 0;
3, fiber class name: Nature of the Fiber class: can be instantiated by the child class: the main attribute of the public inheritance Absline class: Inheritance Property omitted; the primary interface of the class: // Get the type of network device NetlementType Gettype (Void ); // Set line physical length Virtual void setLength (int _Length); // Get line physical length Virt Getlength (Void);
