Abstract

A method is disclosed comprising: instantiating, on a first device, a plurality of first connection objects; generating, by the first device, a first set of connection parameters that is associated with the plurality of first connection objects; transmitting the first set of connection parameters from the first device to a second device; receiving from the second device a second set of connection parameters, the second set of connection parameters being associated with a plurality of second connection objects that are instantiated on the second device; updating, by the first device, each of the first connection objects based on the second set of connection parameters; and transmitting, from the first device to the second device, a confirmation that a plurality of communications channels is established.

First claim

The invention claimed is:

1. A method comprising:
instantiating, on a first device, a plurality of first connection objects;
generating, by the first device, a first set of connection parameters that is associated with the plurality of first connection objects;
transmitting the first set of connection parameters from the first device to a second device;
receiving from the second device a second set of connection parameters, the second set of connection parameters being associated with a plurality of second connection objects that are instantiated on the second device;
updating, by the first device, each of the first connection objects based on the second set of connection parameters, wherein updating each of the first connection objects includes: retrieving a value of a derivable connection parameter from the second set of connection parameters, generating a set of values for the derivable connection parameter based on the retrieved value of the derivable connection parameter; and copying each of the values in the set into a different one of the plurality of first connection objects; and
transmitting, from the first device to the second device, a confirmation that a plurality of communications channels is established,
wherein each of the communication channels is associated with a different object pair, each object pair including a respective one of the plurality of first connection objects and a respective one of the plurality of second connection objects.

2. The method of claim 1 , wherein:
generating the first set of connection parameters includes identifying a common connection parameter and inserting a single copy of a value of the common connection parameter in the first set of connection parameters, and
the common connection parameter includes a parameter having a same value in each of the first connection objects.

3. The method of claim 1 , wherein:
generating the first set of connection parameters includes identifying a unique connection parameter and inserting a plurality of values of the unique connection parameter into the first set of connection parameters, and
the unique connection parameter includes a connection parameter whose value is different in each of the first connection objects.

4. The method of claim 1 , wherein:
updating the plurality of first connection objects based on the second set of connection parameters further includes retrieving a value of a common connection parameter from the second set of connection parameters and coping the value of the common connection parameter into each of the first connection objects,
the common connection parameter includes a parameter having a same value in each of the second connection objects.

5. The method of claim 1 , wherein updating the plurality of first connection objects based on the second set of connection parameters further includes:
retrieving a plurality of values of a unique connection parameter from the second set of connection parameters, and
copying each of the plurality of values into a different one of the plurality of first connection objects.

6. A method comprising:
instantiating, on a first device, a plurality of first connection objects;
generating, by the first device, a first set of connection parameters that is associated with the plurality of first connection objects;
transmitting the first set of connection parameters from the first device to a second device;
receiving from the second device a second set of connection parameters, the second set of connection parameters being associated with a plurality of second connection objects that are instantiated on the second device;
updating, by the first device, each of the first connection objects based on the second set of connection parameters; and
transmitting, from the first device to the second device, a confirmation that a plurality of communications channels is established,
wherein each of the communication channels is associated with a different object pair, each object pair including a respective one of the plurality of first connection objects and a respective one of the plurality of second connection objects,
wherein generating the first set of connection parameters includes identifying a derivable connection parameter and inserting only one value of the derivable connection parameter in the first set of connection parameters, the derivable connection parameter includes a connection parameter whose value is different in each of the plurality of first connection objects, such that a first value of the derivable connection parameter in one of the first connection objects is derivable from a second value of the derivable connection parameter in another one of the first connection objects.

7. An electronic device, comprising:
a memory; and
at least one processor operatively coupled to the memory, the at least one processor being configured to perform the operations of:
instantiating a plurality of first connection objects;
generating a first set of connection parameters that is associated with the plurality of first connection objects;
transmitting the first set of connection parameters to a remote device;
receiving from the remote device a second set of connection parameters, the second set of connection parameters being associated with a plurality of second connection objects that are instantiated on the remote device;
updating each of the first connection objects based on the second set of connection parameters, wherein updating each of the first connection objects includes: retrieving a value of a derivable connection parameter from the second set of connection parameters, generating a set of values for the derivable connection parameter based on the retrieved value of the derivable connection parameter; and copying each of the values in the set into a different one of the plurality of first connection objects; and
transmitting, to the remote device, a confirmation that a plurality of communications channels is established,
wherein each of the communication channels is associated with a different object pair, each object pair including a respective one of the plurality of first connection objects and a respective one of the plurality of second connection objects.

8. The electronic device of claim 7 , wherein:
generating the first set of connection parameters includes identifying a common connection parameter and inserting a single copy of a value of the common connection parameter in the first set of connection parameters, and
the common connection parameter includes a parameter having a same value in each of the first connection objects.

9. The electronic device of claim 7 , wherein:
generating the first set of connection parameters includes identifying a unique connection parameter and inserting a plurality of values of the unique connection parameter into the first set of connection parameters, and
the unique connection parameter includes a connection parameter whose value is different in each of the first connection objects.

10. The electronic device of claim 7 , wherein:
updating the plurality of first connection objects based on the second set of connection parameters further includes retrieving a value of a common connection parameter from the second set of connection parameters and coping the value of the common connection parameter into each of the first connection objects,
the common connection parameter includes a parameter having a same value in each of the second connection objects.

11. The electronic device of claim 7 , wherein updating the plurality of first connection objects based on the second set of connection parameters further includes:
retrieving a plurality of values of a unique
