Abstract
Abstract A system and method for enabling a file server to service a plurality of physical networks, wherein each of the networks has a network protocol of the same type. The system and method comprises a single instance of a filing protocol, and an object-oriented class for implementing a session protocol. The system and method further comprises means for invoking a plurality of session protocol instances, where each one of the plurality of session protocol instances corresponds to one of the plurality of physical networks. Each one of the plurality of session protocol instances services the corresponding physical network and communicates with the single instance of the filing protocol, which enables the single instance of the filing protocol to service the plurality of physical networks.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
104 words
A file server capable of servicing a plurality of physical networks of the same network protocol family, the file server comprising: a single instance of a filing protocol; and means for invoking a plurality of second protocol instances, each one of the plurality of second protocol instances corresponding to one of the plurality of physical networks, wherein each one of the plurality of second protocol instances services the corresponding physical network and communicates with a single instance of the fling protocol, which enables the single instance of the filing protocol to service the plurality of networks, wherein the second protocol is a session protocol.
Claim 2
Dependent Claim
104 words
A file server capable of servicing a plurality of physical networks of the same network protocol family, the file server comprising: a single instance of a filing protocol; and means for invoking a plurality of second protocol instances, each one of the plurality of second protocol instances corresponding to one of the plurality of physical networks, wherein each one of the plurality of second protocol instances services the corresponding physical network and communicates with a single instance of the fling protocol, which enables the single instance of the filing protocol to service the plurality of networks, wherein the second protocol is a session protocol.
Claim 3
Dependent Claim
22 words
A file server as in claim 1 wherein each one of the plurality of second protocol instances creates a corresponding protocol stack.
Claim 4
Dependent Claim
16 words
A file server as in claim 2 wherein the session protocol is an object-oriented class structure.
Claim 5
Dependent Claim
27 words
A file server as in claim 3 wherein the file server further includes a plurality of network interface cards to connect to the plurality of physical networks.
Claim 6
Dependent Claim
15 words
A file server as in claim 4 wherein the network protocol comprises an AppleTalk protocol.
Claim 7
Dependent Claim
16 words
A file server as in claim 5 wherein the filing protocol comprises AppleTalk filing protocol (AFP).
Claim 8
Dependent Claim
16 words
A file server as in claim 6 wherein the session protocol comprises AppleTalk session protocol (ASP).
Claim 9
Independent Claim
97 words
A method for enabling a file server to service a plurality of physical networks of the same network protocol family, the method comprising the steps of: (a) invoking a single instance of a filing protocol; (b) invoking multiple session protocol instances corresponding to each one of the plurality of physical networks using an object-oriented class structure; (c) servicing each one of the plurality of physical networks with the corresponding session protocol instance; (d) communicating between each one of the plurality of physical networks and the single instance of the filing protocol through the multiple session protocol instances.
Claim 10
Independent Claim
97 words
A method for enabling a file server to service a plurality of physical networks of the same network protocol family, the method comprising the steps of: (a) invoking a single instance of a filing protocol; (b) invoking multiple session protocol instances corresponding to each one of the plurality of physical networks using an object-oriented class structure; (c) servicing each one of the plurality of physical networks with the corresponding session protocol instance; (d) communicating between each one of the plurality of physical networks and the single instance of the filing protocol through the multiple session protocol instances.
Claim 11
Dependent Claim
30 words
The method as in claim 8 wherein step (a) further includes the step of: (a1) implementing the single instance of the filing protocol through a first object oriented class structure.
Claim 12
Dependent Claim
27 words
The method of claim 9 wherein step (b) further includes the step of: (b1) implementing the multiple session protocol instances through a second object oriented class structure.
Claim 13
Dependent Claim
28 words

Claim 14
Dependent Claim
26 words
The method of claim 11 wherein step (b) further includes the step of: (b3) creating a separate protocol stack corresponding to the multiple session protocol instances.
Claim 15
Dependent Claim
36 words
The method of claim 12 wherein step (d) further includes the step of: (d1) communicating between the single instance of the filing protocol and the multiple session protocol instances through a third object oriented class structure.
Claim 16
Dependent Claim
99 words
A computer-readable medium containing program instructions for enabling a file server to service a plurality of physical networks of the same network protocol family, the program instructions for: (a) invoking a single instance of a filing protocol; (b) invoking multiple session protocol instances corresponding to each one of the plurality of physical networks using an object-oriented class structure; (c) servicing each one of the plurality of physical networks with the corresponding session protocol instance; (d) communicating between each one of the plurality of physical networks and the single instance of the fling protocol through the multiple session protocol instances.
Claim 17
Dependent Claim
99 words
A computer-readable medium containing program instructions for enabling a file server to service a plurality of physical networks of the same network protocol family, the program instructions for: (a) invoking a single instance of a filing protocol; (b) invoking multiple session protocol instances corresponding to each one of the plurality of physical networks using an object-oriented class structure; (c) servicing each one of the plurality of physical networks with the corresponding session protocol instance; (d) communicating between each one of the plurality of physical networks and the single instance of the fling protocol through the multiple session protocol instances.
