change information in time, and then generates filtering table
in OpenFlow table format. e unified OpenFlow interfaces
and timely routing update make InSAVO more deployable and
efficient than CPF in the traditional network architecture.
3. e core algorithms of InSAVO are introduced. anks to the
routing updates notification feature provided by it, we design
partial calculating algorithm and invoke it only when network
update happens. Compared with the traditional polling com-
puting method, it will save much CPU resources and will get
better filtering performance. Moreover, a new algorithm that
combines both forwarding and filtering calculation by generat-
ing four-tuple OpenFlow table entries is introduced. ...
