摘要： In some embodiments, the invention involves information routing in networks, and, more specifically, to defining a framework using swarm intelligence and utilization of the defined framework for routing information in the network, especially for cloud computing applications. In an embodiment, information about available information/services is pushed to network nodes using information packets (ants). Nodes requiring services send query packets (ants) and a node may send a response to a query ant when information is available. Ants may be forwarded throughout the network based on popularity of nodes, freshness of information/requests, routing table information, and requests or interest by consumer nodes captured in information routing table. Other embodiments are described and claimed.

摘要： The present invention discloses a method, an apparatus and a system for determining a service transmission path. The method includes: receiving a service chaining object sent by a client based on an expanded path computation element communication protocol (PCEP), wherein the service chaining object contains service processing capacities which service nodes need to provide when transmitting a service in a network; determining at least one service node matched with the service chaining object in the network according to service processing capacities which service nodes in pre-stored service node attribute information are capable of providing; and generating a service transmission path based on the determined service nodes, for transmitting the service initiated by the client. The problems of large flow pressure and low utilization rate of the service nodes deployed in the network may be well solved.
