Abstract

A managed class peer networking framework and associated object-oriented application programming interfaces are presented. An application uses the framework API to communicate with the various peer networking subsystem interfaces. These subsystems utilize lower level Win32 interfaces and services to provide access to the group database, security, and data transfer to other machines. Managed classes are provided for the peer name, identity, cloud, invitation, group, policy, data store, peer and record collections, peer, and record classes. Peer name resolution objects and record search objects are also provided. The peer networking framework of the present invention is particularly applicable to Microsoft'"'"'s .NET Framework.

Claims

1. A method of managing by an application a peer-to-peer identity in a managed framework, the method comprising:

creating a single peer-to-peer networking identity interface object exposing at least four methods to a calling application to enable the calling application to manipulate one or more peer identity objects, wherein the four methods are implemented as a set of objects separate and distinct from the peer-to-peer networking identity interface object and from the calling application, and wherein the at least four exposed methods include

a creating method being one of the at least four methods that receives as input from the calling application via the interface a username, a user class, and a user key and outputs a peer identity object for receipt by the calling application via the interface,

an importing method being one of the at least four methods that outputs for receipt by the calling application via the interface a peer identity object,

a deleting method being one of the at least four methods that receives as input from the calling application via the interface a reference to a peer identity object, and

an enumerating method being one of the at least four methods that outputs for receipt by the calling application via the interface a set of managed peer identity objects registered with a local machine and associated with a first user as an identity collection object;

selecting by the calling application one of the methods exposed by the peer-to-peer networking identity object;

passing by he calling application to the managed peer-to-peer networking identity interface object parameters required by the method selected; and

initiating the selected method.

2. The method of claim 1, wherein the method selected in the step of selecting provides an identity collection object exposing an item method, the method further comprising the steps of selecting the item method, passing to the identity collection object a parameter identifying a particular identity, initiating the item method, and receiving the identity class object identified by the parameter.

3. The method of claim 1, wherein the method selected in the step of selecting provides an identity class object exposing an export method, the method further comprising the steps of selecting the export method to export the identity class object, passing the identity class object export parameters, and initiating the export method.

4. The method of claim 1, wherein the method selected in the step of selecting provides an identity class object exposing a create peer name method, the method further comprising the steps of selecting the create peer name method to create a new peer name class object, passing the identity class object new peer name parameters, and initiating the create peer name method to create a new peer name to associate with the identity class object.

5. The method of claim 1, comprising:

creating a managed set of peer cloud class objects wherein each peer cloud class 9biect of the set of peer cloud class objects contains a unique cloud address type that is the, same for all nodes in a cloud that are reachable by a node of the cloud;

creating a single managed peer-to-peer networking cloud interface object that exposes an enumeration method to a calling application, wherein the enumeration method outputs to the calling application the managed set of peer cloud class objects, wherein the enumeration method is implemented in a set of objects separate and distinct from the managed peer-to peer networking cloud interface object, the calling application, and the peer cloud class objects;

communicating with the managed peer-to-peer networking cloud interface object by the calling application;

passing by the calling application to the managed peer-to-peer networking cloud interface object parameters required by the enumeration method;

initiating the enumeration method, the enumeration method providing a managed cloud collection class object containing the set of peer cloud class objects, the cloud collection class object exposing an item method to select a particular cloud; and

selecting a particular cloud class object by the application using the select method of the cloud collection class object.

6. The method of claim 5, further comprising the steps of initiating a cloud watcher object to notify the application upon a change in the cloud.

7. The method of claim 5, further comprising

creating a peer name registrar managed object;

passing name parameters associated with a peer to the peer name registrar managed object; and

initiating a register method exposed by the peer name registrar managed object, the peer name registrar managed object creating a discoverable peer name managed class object in response thereto, wherein the discoverable peer name managed class object includes a cloud class object that is associated with the peer and that contains a cloud address type and a cloud network scope for which a cloud is valid.

8. The method of claim 7, further comprising the steps of passing peer name parameters to the peer name registrar managed object to identify a discoverable peer name, and initiating an unregistered method exposed by the peer name registrar managed object, the peer name registrar managed object deleting the discoverable peer name class object identified by the peer name parameters.

9. The method of claim 5, further comprising

creating a peer name resolver managed object;

passing peer name parameters to the peer name resolver managed object; and

initiating a start resolution method exposed by the peer name resolver managed object, the peer name resolver managed object returning a discoverable peer name managed class object in response thereto, wherein the discoverable peer name managed class object includes a cloud class object that is associated with the peer and that contains a cloud address type and a cloud network scope for which a cloud is valid.
