System, method, and computer program product for peer-to-peer event ordering using a two part event identifer

A non-transitory computer readable medium storing computer code executable by a processor to perform a method comprising:

• establishing, by a first peer device, a peer-to-peer communication channel with a second peer device;
• initializing, by the first peer device, a current event identifier at the first peer device, wherein the second peer device initializes a current event identifier at the second peer device that is different from the current event identifier initialized at the first peer device;
• communicating, by the first peer device with the second peer device over the peer-to-peer communication channel, a plurality of events configured in accordance with a communication protocol that includes with each event of the plurality of events an event identifier that is the current event identifier of a sender of the event, wherein the current event identifier includes two portions that are updated differently when sending and receiving events;
• and
• ordering, by the first peer device, the events in the plurality of events, using the event identifier included with each of the events in the plurality of events.

An apparatus, comprising:

• a computer processor of a first peer device for:
• establishing a peer-to-peer communication channel with a second peer device;
• initializing, by the first peer device, a current event identifier at the first peer device, wherein the second peer device initializes a current event identifier at the second peer device that is different from the current event identifier initialized at the first peer device;
• communicating, with the second peer device over the peer-to-peer communication channel, a plurality of events configured in accordance with a communication protocol that includes with each event of the plurality of events an event identifier that is the current event identifier of a sender of the event, wherein the current event identifier includes two portions that are updated differently when sending and receiving events;
• and
• ordering the events in the plurality of events, using the event identifier included with each of the events in the plurality of events.
