Abstract: The embodiments provide peer cache filling. The peer cache filling allocates a set of caching servers to distribute content in response to user requests with a limited first subset of the set of servers having access to retrieve the content from an origin and with a larger second subset of the set of servers retrieving the content from the first subset of servers without accessing the origin. The peer cache filling dynamically escalates and deescalates the allocation of the caching servers to the first and second subsets as demand for the content rises and falls. Peer cache filling is implemented by modifying request headers to identify designated hot content, provide a request identifier hash result for identifying the ordering of servers, and provide a value for designating which servers in the ordering as primary server with access to the origin.

Abstract: For a multi-tenant environment, some embodiments of the invention provide a novel method for forwarding tenant traffic through a set of service machines to perform a set of service operations on the tenant traffic. In some embodiments, the method performs a classification operation on a data message flow of a tenant, in order to identify a set of service operations to perform on the data message flow. For some data message flows, the classification operation selects the identified set of service operations from several candidate sets of service operations that are viable service operation sets for similar data message flows of the tenant. In some embodiments, the classification operation is based on a set of attributes associated with the data message flow (e.g., five tuple identifier, i.e., protocol and source and destination ports and IP addresses).

Abstract: Techniques for use in network incident identification are described. In response to an occurrence of an unknown network incident, a plurality of log messages (e.g. syslog messages) are received from a plurality of network components in one or more networks. In one illustrative example, a plurality of relationships between interfaces and events are derived from the received log messages and characterized as a plurality of graphical component relationships. One or more groups of connected components are determined from the graphical component relationships and network component connection data which indicate interface relationships of the network components. Here, groups of connected components may be logically joined based on the network component connection data indicating one or more interface relationships.

Abstract: A connection from first terminal CL11, Cl12 to m of relay servers RS1 to RS4 is performed and a connection from second terminal CL21, CL22 to n thereof is performed to relay a communication between the terminals with one of the relay servers connected in common to both of the terminals set to be an active relay server. If a failure occurs in the active relay server, the other relay server connected in common to the first terminal and the second terminal is searched to relay a communication between the terminals with the relay server set to be an alternative relay server at the first terminal and the second terminal. Consequently, a data communication between the terminals is performed through the relay server selected optionally, and furthermore, adjustment for determining the alternative relay server is performed on the terminal side if a failure occurs in an active relay server.
