The hostControlTable + -- controls which interfaces this function is performed on, + -- and contains some information about the process. On + -- behalf of each hostControlEntry, data is collected on an + -- interface and placed both the hostTable and the + -- hostTimeTable. If the monitoring device finds itself + -- short of resources, it may delete entries as needed. It + -- is suggested that the device delete the least recently + -- used entries first. + + -- The hostTable contains entries for each address + -- discovered on a particular interface. Each entry + -- contains statistical data about that host. This table + -- is indexed by the MAC address of the host, through + -- which a random access may be achieved. + + -- The hostTimeTable contains data in the same format as the + -- hostTable, and must contain the same set of hosts, but is + -- indexed using hostTimeCreationOrder rather than hostAddress. + -- The hostTimeCreationOrder is an integer which reflects + -- the relative order in which a particular entry was + + + -- discovered and thus inserted into the table.

Thus the association + -- between hostTimeCreationOrder and hostTimeEntry may be + -- broken at any time. + + -- The hostTimeTable has two important uses. The first is the + -- fast download of this potentially large table. Because the + -- index of this table runs from 1 to the size of the table, + -- inclusive, its values are predictable. This allows very + -- efficient packing of variables into SNMP PDU's and allows + -- a table transfer to have multiple packets outstanding. + -- These benefits increase transfer rates tremendously. + + -- The second use of the hostTimeTable is the efficient + -- discovery by the management station of new entries added + -- to the table. After the management station has + -- downloaded the entire table, it knows that new entries + -- will be added immediately after the end of the current + -- table. It can thus detect new entries there + -- and retrieve them easily. + + -- Because the association between hostTimeCreationOrder and + -- hostTimeEntry may be broken at any time, the management + -- station must monitor the related hostControlLastDeleteTime + -- object. When the management station thus detects a deletion, + -- it must assume that any such associations have been broken, + -- and invalidate any it has stored locally. This includes + -- restarting any download of the hostTimeTable that may have + -- been in progress, as well as rediscovering the end of the + -- hostTimeTable so that it may detect new entries. If the + -- management station does not detect the broken association, + -- it may continue to refer to a particular host by its + -- creationOrder while unwittingly retrieving the data + -- associated with another host entirely.
