A method, apparatus, and computer program product are provided for facilitating randomized port allocation. An apparatus may include a processor configured to receive a port allocation message from a network management entity. The port allocation message may comprise an encryption key, an initial input value, and a value indicating a number of ports allocated to the apparatus for communication on a network. The processor may be further configured to calculate at least one port allocated to the apparatus with an encryption function based at least in part upon the encryption key and initial input value. Corresponding methods and computer program products are also provided.

Methods, apparatuses, and computer program products for facilitating randomized port allocation

A method for providing a multipath scheduler may include causing generation of a lookup table of action rules defining actions corresponding to respective different states in which each of the states is a weighted description of performance measures associated with a data interface, and enabling utilization of the lookup table at a predefined periodicity during communication in a multipath communication environment to identify a selected data interface among a plurality of available data interfaces based on current performance measures associated with the plurality of available data interfaces. A corresponding apparatus and computer program product are also provided.

Method for multipath scheduling based on a lookup table

A method including changing an access address of a network interface of a wireless network node, changing a frame sequence number of a network interface of the wireless network node in an unpredictable manner, and performing the changing of the access address and changing of the frame sequence number in a coordinated manner.

Location privacy in communication networks

A method including operating in an apparatus a multi-point multi-path transport protocol providing a multi-point multi-path transport connection, and using said apparatus in said multi-point multi-path transport connection as a part of an end system formed by said apparatus and other apparatuses that are physically distinct from said apparatus.

Multi-path transport

A multipath data communication network structure in which probing middle-boxes send periodical probe messages through their different interfaces and subsequent routers map the probe messages through their randomly selected interfaces until each probe message arrives at a destination, engages to a loop or meets a time-to-live limit. The probing middle boxes select a random interface for each probe message and furnish their routable identification and a temporary random number correlated to the selected interface to each probe messages. Subsequent multipath routers select a random outgoing interface and random forwarding state descriptor (FSD) and temporarily correlate the selected random outgoing interface with the FSD and add the FSD to the probe message. The probe messages provide different destinations with various hidden paths. Each hidden path enables forwarding of packets from probing middle-boxes to the destination without identifying any routable address en-route to the destination. The destination then provides a data source with the hidden path. Each multipath network element only store their mappings related to the paths for limited term so that each path expires and vanishes after the term. Attackers are not issued a new path and thus denial of service attacks are shortly stopped.
