Resource negotiation for cloud services using a messaging and presence protocol

摘要

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.

1. A method comprising:
sending from a client in a first network device a first session-initiate message to a second network device associated with a first datacenter, the first session-initiate message comprising resource request information for services provided by a service node in the first data center in order to establish an Open System Interconnect (OSI) model network layer (L3), data link layer (L2), or associated convergence layer based service connection between the first network device and the service node in the first data center, wherein the first session-initiate message is based on a messaging and presence protocol; receiving a session-accept message at the client comprising resource response information configured to accept the service connection on behalf of the service node and provide network layer (L3), data link layer (L2), or associated convergence layer based service connection information in order for the first network device to establish the service connection with the service node in the first data center, wherein the session-accept message is based on the messaging and presence protocol; and in response to receiving the session-accept message, establishing the service connection.
