`[1.5] (iii) if there is at least
`one protocol specific operation to be
`performed on the packet for the
`particular protocol at the particular
`layer level, the one or more protocol
`specific operations to be performed
`on the packet for the particular
`protocol at the particular layer level;

`[1.6] (c) performing the protocol
`specific operations on the packet
`specified by the set of protocol
`descriptions based on the base
`protocol of the packet and the
`children of the protocols used in the
`packet,
`
`[10.6] (c) performing the protocol
`specific operations on the packet
`specified by the set of protocol
`descriptions based on
`the base
`protocol of
`the packet and
`the
`children of the protocols used in the
`packet,
`
`[17.6] (c) performing the protocol

`field, the searching including
`indexing the data structure until a
`valid entry is found, and
`whereby the data structure is
`configured for rapid searches using
`the index set.
