Appeal No. 2000-2193
Application No. 08/877,465
Claims 4 through 6, 9, 14 and 16 through 18 stand rejected
under 35 U.S.C. § 103(a) as being unpatentable over Edsall in
view of Hyden.
Reference is made to the briefs (paper numbers 11 and 13)
and the answer (paper number 12) for the respective positions of
the appellant and the examiner.
OPINION
All of the claims on appeal require that the tag in the
encapsulated packet be placed between two media headers.
The examiner is of the opinion (answer, pages 4 and
9 through 11) that the interswitch link (ISL) source address (SA)
is a tag between an ISL destination address (DA) media header and
an Ethernet header (i.e., VLAN) in the ISL encapsulated packet
600 (Figure 6).
Appellant argues (brief, pages 9 and 10; reply brief, pages
2 and 3) that the examiner has improperly parsed an ISL header
comprised of an ISL destination address 602 and an ISL source
address 604 into both a header and a tag placed at the beginning
of an ISL encapsulated packet 300 to arrive at the claimed
invention.
