HP Network Teaming Virtual Miniport Driver
IGMP join messages elicited by the general query are received and transmitted to a switched network. A particular example embodiment of a failover method includes monitoring or tracking traffic information to determine a suitable failover response.
HP NIC Teaming, Hyper-V, and Seemingly Random Connection Issues
In response to failover, one or more IGMP reports are sent out a primary aggregation group. The IGMP reports contain a list of HP Network Teaming Virtual Miniport multicast streams. Joined groups are retained on non-primary aggregation groups. The multicast streams can be joined on a new primary aggregation group before failover from a previous aggregation group.

After failover, one or more leave group message can be sent from the previous primary aggregation group, ensuring HP Network Teaming Virtual Miniport of the multicast streams. In another embodiment of a failover method, in the event of a failover condition, link connectivity is determined. For a connected link, one or more IGMP Leave Group messages are sent so that multicast streams to ports outside the new primary aggregation group are terminated. For a disconnected link, an indication directed to the previous primary aggregation group is sent showing an IGMP Leave Group message is pending.

When renewed link connectivity occurs, one or more IGMP Leave Group messages are sent so that multicast HP Network Teaming Virtual Miniport to ports outside the new primary aggregation group are terminated. Data streams in a communication system are shown from a network to a team Teaming system behavior can be analyzed as a server joins a multicast group using IGMP.
In an example of team operation, team data can be sent to each member port M. IGMP traffic is not sent to nonmember ports N which are not members of the multicast group.
In a description of IGMP behavior, multicast routers send Queries to hosts to determine which hosts consent to be part of that group. Hosts then send a Report informing the network device which multicast groups are consented to be joined. A host sends a Report immediately upon consenting to join a group HP Network Teaming Virtual Miniport does not wait for a Query.

The host repeats the send once or twice in case of the initial is dropped. Some hosts, for example called IGMPv1 hosts, may silently leave a group by not responding to a Query.
HP Network Teaming Virtual Miniport Examples of IGMP messages and types may be defined. The first byte in the message contains the type of IGMP message. Various operating systems support different versions of IGMP. The failover techniques disclosed herein extend capabilities of a teaming driver to take IGMP messages into consideration.
The server may run an application that can join a multicast group. The join message is then sent out the primary aggregation, causing the aggregation HP Network Teaming Virtual Miniport all ports on network devices along the path to become part of the multicast group. In the case of HP Network Teaming Virtual Miniport failover scenario, the new team member will be connected to another port or even another network device.
The new primary will be unable to receive data from the multicast stream until a timeout occurs and a network device re-sends a query to join the group, which could be several minutes. During the failover, if the IGMP report is sent out the new primary, causing the new primary to join the multicast group, and the old primary aggregation is no longer connected to the switch but is re-connected before the port times out the status of the multicast group.
The traffic continues to come down a nonprimary port. The traffic is dropped by a Network HP Network Teaming Virtual Miniport Intermediate Driver NTID but what is desired is to maintain groups on any ports upon which the multicast stream is not received. The illustrative failover techniques ensure the team can maintain connectivity with the multicast group in a failover.
NTID will also leave all joined groups on non-primary aggregation groups. An efficient technique for a failover scenario has a seamless transition from the old primary to the new primary. After the failover has occurred, the old primary will send leave group messages to ensure the multicast does not continue to be sent to any other team member.
If a leave group message cannot be sent due to link loss, HP Network Teaming Virtual Miniport flag will be set on the aggregation group that an IGMP leave group message is pending.
When the HP Network Teaming Virtual Miniport is returned, the leave group message will be sent from the aggregation. In case of a fail-back, the leave group will still be sent, but a report will be sent immediately after during the failover logic. A result is that when multiple multicast streams are used, several streams may be transmitted on non-receiving team members. The team then cannot receive data from the multicast streams on the non-receiving team members.
Instead, for the illustrative failover techniques all IGMP traffic will be sent out the primary aggregation group. In an example embodiment, the illustrative failover technique can be implemented by adding to a context data structure.
A variable can be added to the aggregation group context to determine whether a leave group command is still pending on a particular aggregation.
