Abstract
A centralized control processor provides a unified management mechanism for multiple multicast switches or servers running virtual switches that is also capable of sending query messages based upon a subset of ports.
Claims20
A system comprising:
- at least first and second computer servers;
- at least first and second virtual machines (VM) implemented by at least the first server and at least a third VM implemented by the second server;
- a first virtual switch on the first server and communicating with the first and second VM and with a network;
- a second virtual switch on the second server and communicating with the third VM and the network;
- and
- a centralized control processor communicating with both servers to coordinate multicast messaging at least within the servers.
3 more elements
Method comprising:
- providing plural local switches;
- providing a centralized control processor communicating with the local switches;
- and
- using the centralized control processor to prevent at least a first local switch from receiving multicast messages not addressed to any entity behind the first local switch.
1 more element
Apparatus comprising:
- a centralized control processor communicating with plural servers each executing at least one virtual machine and a respective switch connecting the VM to a network, the centralized control processor coordinating multicast messaging between the servers and the network.
