Abstract
Abstract A context-dependent, multiply binding name resolution system. A name resolver is provided, connected to either a requester's system or a receiver's system, or both. Requests to a given service or domain name are resolved to the appropriate IP address. The intended recipient of the request is resolved based upon a combination of one or more predetermined criteria, including: information about the sender (e.g. geographical location, specific requester identity, etc.); information about the intended recipient (e.g. load balance at the receiver, type of service, etc.); information contained within the request itself (e.g. type of service requested); or other information (time of day, date, random selection of recipient, e.g.). The system is implemented in hardware and/or software, and the resolution criteria can be made interdependent or independent.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
86 words
A system for name resolution of at least one request directed to a destination name of a
receiver and issued from a requester system, including: a name resolver connected to the requester service and including predetermined information correlating a plurality of destination addresses with said
destination name; a criteria selection subsystem configured to provide a selection of at least one said
destination address based upon at least one predetermined criterion; and a destination address binder configured to bind said destination name with said
selected destination address.
Claim 2
Dependent Claim
23 words
The system of claim 1, wherein said at least one predetermined criterion includes a criterion
based upon information explicitly contained within said request.
Claim 3
Dependent Claim
14 words
The system of claim 2, wherein said information includes an address of said requester.
Claim 4
Dependent Claim
20 words
The system of claim 2, wherein said information is based upon at least a portion of contents
of said request.
Claim 5
Dependent Claim
33 words
The system of claim 4, wherein said portion of said contents includes at least one of: a type of service requested by said request; and a quality of service requested by said request.
Claim 6
Dependent Claim
24 words
The system of claim 1, wherein said at least one predetermined criterion includes a criterion
based upon information not explicitly contained within said request.
Claim 7
Dependent Claim
16 words
The system of claim 6, wherein said information pertains to a geographical region of said
requester.
Claim 8
Dependent Claim
16 words
The system of claim 6, wherein said information pertains to a geographical region of said
receiver.
Claim 9
Dependent Claim
15 words
The system of claim 6, wherein said information includes load information relating to said
receiver.
Claim 10
Dependent Claim
17 words
The system of claim 6, wherein said information includes at least one of time and date
information.
Claim 11
Dependent Claim
16 words
The system of claim 1, wherein said binding is to a port at said destination address.
Claim 12
Dependent Claim
23 words
The system of claim 1, wherein said binding is based at least in part upon a random selection
of one said destination address.
Claim 13
Independent Claim
87 words
A method for context-dependent binding of a destination name to a destination address in
a name resolver having a predetermined set of binding criteria and predetermined correlations of
destination names with destination addresses, wherein at least one said correlation is a multiple
correlation correlating a plurality of said destination addresses with a single destination name,
including the steps of: (1) receiving said request at said name resolver; and (2) based upon said multiple correlation, retrieving at least one said destination address
from said plurality of destination addresses.
Claim 14
Dependent Claim
23 words
The method of claim 13, further including after step 2, the step of: (3) binding said retrieved destination address to said destination name.
Claim 15
Dependent Claim
21 words
The method of claim 14, further including after step 3, the step of: (4) transmitting said request with said destination address.
Claim 16
Dependent Claim
18 words
The method of claim 13, wherein said multiple correlation is based upon information
explicitly contained within said request.
Claim 17
Dependent Claim
21 words
The system of claim 13, wherein said multiple correlation is based upon at least a portion
of contents of said request.
Claim 18
Dependent Claim
39 words
The system of claim 13, wherein said multiple correlation is based upon at least one of: an address of said requester; and a type of service requested by said request; and a quality of service requested by said request.
Claim 19
Dependent Claim
19 words
The system of claim 1, wherein said multiple correlation is based upon information not
explicitly contained within said request.
Claim 20
Dependent Claim
41 words
The system of claim 19, wherein said multiple correlation is based upon at least one of: a geographical region of said receiver; load information relating to said receiver; time information; date information; and a random factor generated by said name resolver.
Claim 21
Independent Claim
96 words
A system for name resolution of at least one request directed to a destination name of a
receiver and issued from a requester system, the request information relating to caller context, the
system including: a name resolver connected to the requester service and including predetermined information correlating a plurality of service names with said caller
context; a service selection subsystem configured to provide a selection of at least one said
service name based upon said caller context; and a host name selection subsystem configured to return a host name based corresponding
to said selected service name.
Claim 22
Dependent Claim
37 words
The system of claim 1, wherein said at least one predetermined criterion includes: a first criterion based upon information explicitly contained within said request; and a second criterion based upon information not explicitly contained within said request.
