NDS_BACKLINK_OPEN

NDS_BACKLINK_OPEN is a traffic type that is only used if either CheckEachNewOpenConnection or CheckEachAlreadyOpenConnection was set to 1 during the corresponding NDS_BACKLINKS query.

This query is generated whenever CheckEachNewOpenConnection is 1 and NDS* needs to open a new connection for backlinking or CheckEachAlreadyOpenConnection is 1 and NDS needs to reuse an already existing connection.

• Version (Input Only, Type INTEGER)

  The version of NDS.

• ExpirationInterval (Input and Output, Type INTEGER)

  If ConnectionIsAlreadyOpen is TRUE, ExpirationInterval will be set to the expiration interval already set on the existing connection. Otherwise it will be set to the ExpirationInterval assigned in the NDS_BACKLINKS query. A zero value indicates that the default (2 hours) should be used. On exit, the value of this variable is assigned as the expiration interval for the connection

  <0,0 Use the default expiration interval (default)

  >0 Expiration Interval to be assigned to this connection

• ConnectionIsAlreadyOpen (Input Only, Type BOOLEAN)

  This variable is TRUE if NDS wishes to reuse an existing connection and FALSE if it needs to create a new connection.

  • TRUE

    NDS believes it already has a connection to this address and can reuse that connection.

  • FALSE

    NDS does not have a connection to this address and must create one.

• ConnectionLastUsed (Input Only, Type TIME)

  If ConnectionIsAlreadyOpen is TRUE, then ConnectionLastUsed is the last time that a packet was sent from NDS using this connection. Otherwise, it will be zero.

  • TRUE

    ConnectionLastUsed is the time that NDS last sent a packet on this connection.

  • FALSE

    ConnectionLastUsed will be zero.
