This application provides a method for allocating an IP address, including: establishing, by a session management network element, a session for a terminal apparatus, where the session is used for transmitting a data packet via a control plane network element; allocating, by the session management network element, an IP address to the terminal apparatus; and sending, by the session management network element, the data packet to the terminal apparatus via a mobility management network element, where the data packet includes the IP address. In a case in which the terminal apparatus can obtain the IP address without establishing an additional connection channel, the terminal apparatus can obtain the IP address more flexibly, and occupation of excessive signaling resources can be avoided.

Disclosed is segment routing for load balancing. A network path identification device can receive a first service request identifying a first service. The first service request can originate from a first client device. The network path identification device can select, from a Source Routing (SR) list, a first service node to provide the first service and a first network path to reach the first service node. The SR list can include a set of service nodes that provide the service and one or more network paths to reach each service node from the set of service nodes. The network path identification device can then transmit a response message to the first service request. The response message can identify the first service node and the first network path so that the first client device can use the first network path to request the first service from the first service node.

Provided is a communication system that includes first and second communication devices operating in conformance with IPv6 requirements, in which the first communication device (100) determines whether an own IP address for communication is utilized or not by monitoring a communication status, generates a response request message requesting a response message to the second communication device when the own IP address is determined to be no longer required, designates the own IP address as a destination of the response message in the response request message, and transmits the response request message to the second communication device (200) during a period when a Neighbor Cache entry related to the own IP address in the second communication device is in STALE state after transition from REACHABLE state.

A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.

In one embodiment, a data packet message is provided which includes a routing header configured to accommodate both a deterministic source route and a probabilistic source route for encoding a nodal source route. The nodal source route is selectively encoded with one or both of a deterministic source route and a probabilistic source route based upon one or more predetermined criteria.

Configuration of firewall functionality and/or determining positioning for routers operating within a multi-router network is contemplated. The firewall functionality configured for one or more of the routers may be based router positioning within the multi-router network. The firewall functionality may be automatically selected according to the router positioning in order to facilitate dynamic and/or adaptive router configuring.

One embodiment relates to data routing using first and second pieces of IP type equipment, the second piece of equipment being suitable for communicating with a management node of a sensor network. The sensors may have respective IP addresses that are generated by said management node, the node also having a function of routing data in the sensor network. The method includes, in a router, generating an address for the second piece of equipment, verifying the availability of the address in the sensor network from the management node, and if the address is available, requesting the management node to add the second piece of equipment in the sensor network.

A method for routing a request for content from a content provider through an IPv6 network is described, the IPv6 network being an information centric network (ICN) in which content is directly addressed using at least a portion of an IPv6 address. The method includes receiving, at an IPv6 network, a request for content, determining that the request does not comprise an ICN address. The method further includes intercepting the request, and translating the request into an IPv6 address in which at least a portion of the address is directed to or associated with the piece of content. Systems and methods described herein address problems arising from the interaction between IP and ICN networking models.

In one embodiment, a tracking device detects a first device connecting to a computer network, and forces an install of fake routing information on the first device that is unique to the first device. Upon detecting a second device connecting to the computer network, the second device having at least one identifying property in common with the first device and at least one identifying property differing from the first device, the tracking device may then query the second device to determine if the second device knows the fake routing information unique to the first device. As such, the tracking device may then determine that the second device is the first device in response to the second device knowing the fake routing information unique to the first device.

Systems and methods for geofence information delivery are disclosed. A multiplicity of devices constructed and configured in network communication in a region of interest via a peer-to-peer network. The multiplicity of devices store cached geofence information for the region of interest. The multiplicity of devices on the peer-to-peer network are operable to convert between an IP address and a geographic location. Each of the multiplicity of devices is operable to query peer devices on the peer-to-peer network for geofences associated with an IP address or a geographic location. At least one peer device is operable to deliver one or more geofences associated with the IP address to the querying device via zero-configuration networking or web service.
