Abstract

Various embodiments include at least one of systems, methods, software, and data structures for peer-to-peer exchange of at least a portion of networked collaboration session data. Client and server solutions allow for switching between peer-to-peer and server-centric modes of collaboration data sharing. Some embodiments also allow for sharing of data of a first type via a collaboration server and data of a second type via peer-to-peer connections.

Claims

1. A computer implemented method comprising:

connecting to a collaboration session, hosted by a collaboration server, over a network;

evaluating peer-to-peer connectivity factors regarding a connection to the collaboration server;

generating factor data using the peer-to-peer connectivity factors;

upon a determination that a peer-to-peer connection with at least one collaboration session participant is to be established based on the factor data, establishing a peer-to-peer connection with the at least one collaboration session participant; and

participating in the collaboration session with at least a portion of collaboration session data to be exchanged with the at least one collaboration session participant over the peer-to-peer connection while at least one other portion of collaboration session data is exchanged concurrently via the collaboration server.

2. The computer implemented method of claim 1, wherein the peer-to-peer connectivity factors include at least one of:

a download network connection rate;

an upload connection rate;

a version of a software application plug-in; and

availability of network communication ports for sending and receiving data over the network.

3. The computer implemented method of claim 1, wherein evaluating peer-to-peer connectivity factors regarding the connection to the collaboration server is performed at periodic intervals while connected to the collaboration session.

4. The computer implemented method of claim 1, further comprising:

subsequent to participating in the collaboration session with at least a portion of collaboration session data to be exchanged with the at least one collaboration session participant over the peer-to-peer connection, receiving instructions to exchange all collaboration session data via the collaboration server.

5. The computer implemented method of claim 1, wherein connecting to the collaboration session includes downloading an instruction set executable on a local computing device, the instruction set including instructions to perform the at least one of determining, establishing, and participating.

6. The computer implemented method of claim 1, wherein participating in the collaboration session includes:

displaying a representation of received collaboration data;

capturing input received on a local computing device performing the method; and

transmitting the captured input to the at least one collaboration session participant via one of the collaboration server or the peer-to-peer connection.

7. The computer implemented method of claim 1, wherein the portion of collaboration session data exchanged with the at least one collaboration session participant over the peer-to-peer connection includes one or more of audio data and video data.

8. A computer implemented method comprising:

receiving collaboration session connection status data regarding each of a plurality of participants in a collaboration session;

evaluating the collaboration session connection status data to determine that peer-to-peer connections between the plurality of participants satisfy a determinable criterion;

transmitting, over the network to the plurality of participants satisfying the determinable criterion, instructions to establish a peer-to-peer connection; and

sharing collaboration data received from at least one of the plurality of participants by transmitting the collaboration data from a collaboration server to other participants, wherein the collaboration data is shared while other collaboration data is exchanged concurrently via peer-to-peer connections between the participants satisfying the determinable criterion.

9. The computer implemented method of claim 8, further comprising:

upon receipt of additional collaboration session connection status data, evaluating the additional collaboration session connection status data; and

determining that one or more peer-to-peer connections do not satisfy the determinable criterion; and

transmitting a peer-to-peer connection termination message to each participant directing the participants to terminate the peer-to-peer connections and to exchange all collaboration data via the collaboration server performing the computer implemented method.

10. The computer implemented method of claim 8, wherein the transmitted instructions direct each participant to exchange collaboration data of at least one data type via the peer-to-peer connections.

11. The computer implemented method of claim 8, wherein evaluating the collaboration session connection status data to determine that peer-to-peer connections between the plurality of participants satisfy the determinable criterion includes evaluating, alone or in combination, collaboration session connection status data representative of at least one of:

a number of peer-to-peer connections;

upload rates of each participant;

download rates of each participant;

available network communication ports of each participant; and

a version of a software element used by each participant to participate in the collaboration session.

12. The computer implemented method of claim 8, further comprising:

determining that one or more data streams of the collaboration session may be transitioned to one or more peer-to-peer connections between the plurality of participants.

13. The computer implemented method of claim 8, further comprising:

receiving a command from a participant to record the collaboration session;

transmitting a peer-to-peer connection termination message to each participant directing the participants to terminate the peer-to-peer connections and to exchange all collaboration data via the collaboration server performing the computer implemented method; and

recording the collaboration session.

14. A collaboration server comprising:

a bus;

a network interface coupled to the bus;

a processor coupled to the bus;

a memory device coupled to the bus and holding an instruction set executable on the processor to cause the system to;

maintain, in the memory device, collaboration session connection status data of a collaboration session in progress, the collaboration session connection status data received over the network interface from each of a plurality of participants;

evaluate the collaboration session connection status data;

determine that peer-to-peer connections between the participants satisfy a determinable criterion based on the evaluation of the collaboration session connection status data;

transmit, over the network interface, peer-to-peer connectivity data to each participant based on the determination that peer-to-peer connections satisfy the determinable criterion, wherein the peer-to-peer connectivity data includes instructions to the participants to exchange a first data type via the peer-to-peer connections between the participants; and

when collaboration data is received from a participant, transmit the received collaboration data from the collaboration server to other participants while collaboration data of the first data type is exchanged concurrently via the peer-to-peer connections between the participants.

15. The collaboration server of claim 14, wherein the instruction set is further executable on the processor to cause the system to:

reevaluate collaboration session connection status data during the collaboration session upon receipt of additional collaboration session connection status data; and

transmit a peer-to-peer connection termination message to each participant directing the participants to terminate the peer-to-peer connections and to exchange all collaboration data including the first data type via the system based on a determination that one or more peer-to-peer connections do not satisfy the determinable criterion.

16. The collaboration server of claim 14, wherein the instruction set is further executable on the processor to cause the system to receive the collaboration session connection status data from each of the participants.
