Techniques are provided herein for a device in a network to receive information configured to indicate a control plane traffic load level for one or more server devices that are configured to manage traffic for messaging and presence clients communicating via a messaging and presence protocol. The control plane traffic is associated with the messaging and presence protocol. A determination is made as to when the control plane traffic load level has become unbalanced among the two or more server devices and in response to determining that the control plane traffic load level has become unbalanced, sending a transfer message to one or more clients comprising information configured to initiate migration of one or more clients from a server device that is relatively overloaded to a server device that is relatively underloaded in order to balance the control plane traffic load level among the two or more server devices.

Active load distribution for control plane traffic using a messaging and presence protocol

Techniques are provided for sending from a client in a first network device a first session-initiate message to a second network device that is configured to provide network layer, data link layer, or associated convergence layer based service connection information in order for the second network device to accept or reject a network layer, data link layer, or associated convergence layer based service connection with the first network device. The first session-initiate message is based on a messaging and presence protocol. A session-accept message is received at the client in the first network device that is configured to accept the service connection and provide a network layer, data link layer, or associated convergence layer based service connection information in order for the first network device to establish the service connection with the second network device. The session-accept message is based on the messaging and presence protocol. In response to receiving the session-accept message, the service connection is established.

Resource negotiation for cloud services using a messaging and presence protocol

Data representing capabilities of devices in a data is aggregated on a cluster-basis. Information representing capability attributes of devices in the data center is received. The information representing the capability attributes is analyzed to generate data that groups devices based on similarity of at least one capability attribute. Aggregation data is stored that represents the grouping of the devices based on similarity of the at least one capability attribute and identifies the devices in corresponding groups.

Clustering-based resource aggregation within a data center

Techniques are described for selecting an optimal data center for instantiating a first cloud service. Embodiments of the invention receive a request specifying a topology of a first cloud service to be hosted by one of a plurality of data centers which provide computing resources to host a plurality of cloud services. A suitability value is then determined for each of the data centers which measures a fitness of the data center for instantiating the first cloud service. In one embodiment, the suitability value is determined by calculating a plurality of metric values for the data center, normalizing the metric values and calculating a weighted average of the normalized values. One of the data centers is then selected for instantiating the first cloud service, based at least in part on the determined suitability values.
