Composition.
For example, groove position, port and board are managed by the way of structure of arrays.Exchanged for whole core
Groove position board structure Slot_Struct is defined as array by machine, and array size is the most vat position that core switch is supported
Number, passes through Slot_No（Groove bit number）The data of certain block groove position board can be obtained to point to corresponding array index；Groove position board
Inside configuration preserves the members such as port numbering, port type.The a port counter preserved in the board structure of groove position
Port_No, the port counter can be regarded as vernier or pointer in subsequent applications, a board port of often reaching the standard grade（Abbreviation end
Mouth or interface）Then counter adds 1, to record the port numbering that current business plate is reached the standard grade.Obtain port numbering mode be：
Slot_Struct[Slot_No].Port_No。
The management process of interface index number is：The Base Serial Number of interface index is defined as IF_INDEX_BASE（Here define
For 1）.Reserve Main_Board_Port_Num interface index number and give master control borad, activated business use for master control borad in future；It is false
If Main_Board_Port_Num=64, i.e., interface index number 1~64 keeps for master control borad, and service port is supported for master control borad
Situation can directly use the interface index number.The interface index of the Base Serial Number of business board interface index immediately master control borad
Number, according to above-mentioned it is assumed that the starting call number of business board is 65.Assuming that maximum traffic plate number Board_Num is 8, single groove position is most
Large port number Borad_Port_Num is 64, then line card（That is business board）Interface index sum All_Service_Port_Num=
Board_Num×Borad_Port_Num=8×64=512.XE mouths need to do special processing.Because no matter in time XE mouths reach the standard grade
Or all without can say in proper order on position, therefore poll must be taken to detect the mode in room, i.e., each line the allocation space of XE mouths
