Abstract: A collaboration server transmits a server data structure to each client in a collaboration session for a shared workspace. The server data structure specifies a plurality of network connection metrics and a plurality of corresponding weights. Each client receives the plurality of metrics and weights and determines various values (such as a measured value, normalized value, and/or weighted value) for each metric. Each client also calculates an overall connection value based on a plurality of weighted values determined for the plurality of metrics. Each client generates and displays a connection indicator based on the overall connection value which represents an overall quality of a network connection between the client and the collaboration server. Each client also receives a remote overall connection value corresponding to a remote client and generates and displays a remote connection indicator based on the remote overall connection value.

Abstract: A method and apparatus for presenting the multiple processors of a cluster as a single virtual host to a network wherein the processors are communicatively coupled among themselves and to a network interface. The network interface is communicatively coupled to the network. One of the processors is designated a primary parallel I/O processor. One address is advertised on said network for said multiple processors, and filter trees in the network interface direct the interface to forward packets from the network addressed to that address to the primary parallel I/O processor. Later, the filter tree is modified to direct the network interface to forward a specific subset of the packets directly to a particular processor.
