Abstract:
A system and method for virtualizing a flow switch to be used by application providers in a cloud computing environment is provided. An application provider's packet handling rules are received by a cloud management system. The rules are translated from the application provider's overlay topology to the underlay data center topology. The underlay network elements involved in the received rules can be identified. A translated rule can be decomposed into a plurality of rule portions which are transmitted to the appropriate underlay network elements.
Abstract:
Methods, systems, and computer program products for security context escrowing are provided herein. According to one aspect, a method of operation of a network node for a telecommunications network comprises storing security context information associated with a small data, fast path connection between a wireless device and a first gateway that is serving the wireless device, determining a change in the gateway that is serving the wireless device from the first gateway to a second gateway, and, in response to determining the change, providing the stored security context information to the second gateway for use with the wireless device.
Abstract:
Methods, network address translation (NAT) devices, network nodes and system for allowing identification of a private device in a public network or treating traffic of a private device in a public network. The NAT may allocate a private IPv4 address to the private device, reserve a block of ports on the public IPv4 address for the private device and send an identification of the block of ports to a network node in the public network. The network node of the public network may receive an identification of a block of ports on the public IPv4 address indicating that the block of ports is reserved for the private device and activate a rule for treating traffic of the private device.

Abstract:
Systems and methods are described which provide communication between a correspondent node and a mobile node including receiving a home prefix of the mobile node and a list of correspondent nodes by a mobile access gateway having an access link with the mobile node and submitting proxy binding update messages by the mobile access gateway to a home agent corresponding to the mobile node and to each of the correspondent nodes in the list.
Abstract:
Antenna sharing techniques are described. A mobile computing device may comprise an antenna, a switch to couple to the antenna, and multiple transceivers to couple to the switch. The mobile computing device may also comprise an antenna management module to couple to the switch and the transceivers. The antenna management module may control the switch to electrically connect one of the transceivers to the antenna. Other embodiments may be described and claimed.
Abstract:
Methods, a data source and a router are provided to fragment packets that are to be sent in multicast mode towards a plurality of destinations comprised in a multicast group. Each router along a path leading from the data source towards some of the destinations sends its maximum transmission unit value in an uplink direction. Each router directly connected to the data source calculates a lowest maximum transmission unit based on various maximum transmission unit values received from downstream routers. The data source receives from each of the directly connected routers a maximum transmission unit value, which is certain to be acceptable to all routers and destinations of the multicast group downstream of that directly connected router. The data source selects a lowest one of the received maximum transmission unit values and fragments data contents accordingly.
Abstract:
Methods and nodes are provided for supporting session continuity for terminals capable of having simultaneous accesses while served by a plurality of gateways. Distinct binding cache entries (BCE) are stored for a terminal, each BCE being related to one of the gateways serving the terminal. The BCEs identify the terminal, provide an address allocated thereto for getting access at a gateway, and identify the gateway providing the access. When detection is made that two of more BCEs relate to the same terminal for distinct gateways, address information is sent to each other gateway.
Abstract:
A plurality of networked devices on a communication network host services and instances of those services. These services and service instances are mapped onto destination addresses within a given address space. Thus, the destination addresses provide information about the location of the networked devices, as well as the functional topology of the network. Data packets may be routed to a desired service instance using these destination addresses.
Abstract:
A Mobile Node, A Network Node and a method performed in a visited network of a telecommunications network. The Mobile Node has a home address (HoA) valid in a Mobile Node's home network of the telecommunications network or knows how to generate one. The HoA is used in the visited network. A Pad Translator Generator module generates a Pad Translator (PaT) from at least one protection parameter by applying at least one exclusive-or (XOR) thereon and a Pad Translator Applicator module applies the PaT on at least a portion of a header of a packet using an exclusive-or (XOR) function thereby enabling protection of at least a portion of the HoA in the visited network.
