摘要： The present invention relates to a method and node for efficiently distributing electronic content in a content distribution network (CDN) comprising a plurality of cache nodes. Embodiments of the present invention include a virtual node logically representing a set of cache nodes. The set of cache nodes is in turn defined based on an internal communication cost between the cache nodes. In each of the cache nodes represented by the virtual node statistics regarding content requests is collected, and based on this statistics it is determined whether specific content is to be cached in the virtual node or not. If it is determined to cache specific content in the virtual node, the specific content may be caused to be cached in one or more of the cache nodes represented by the virtual node.

摘要： Illegitimate use of IP addresses is counteracted. A network (1) includes a switch (5) with ports (P1,P2,P3) to subscribers (6,6A) and a port (PN) to a core network (2) with DHCP servers (4, 4a,4b). The switch includes a database (MAC1, MAC2), port numbers (P1, P2) and VLAN identities (VLAN1, VLAN2) for the subscribers (6, 6A) and the filter has a list over trusted DHCP servers. Initially onlY DHCP messages from the subscribers are allowed. When the subscriber (6) requests (M1, M3) for an IP address it is checked that it is a DHCP message with valid subscriber values (MAC1, P1, VLAN1). A respond (M2, M4) with an allocated IP address (IP1) and lease time interval (T1) is checked to come from a trusted DHCP server. If so, a list in the filter (9) with correct information is dynamically generated (MAC1, P1, VLAN1, IP1, T1). A messsage (M5) from the subscriber (6) with false IP address is discarded by the filter. Attempts by the subscriber to use false IP address are counted and a warning signal is generated.

摘要： A Mobile Station (MS), a Base Station System (BSS) and a Mobile Switching Center (MSC) of a cellular network, such as GSM, are disclosed. According to one embodiment, the MS is arranged to carry out one or more security features in its communication with the network. For example, the MS may be arranged to: • by means of information received in a signalling message (0) from the network, discover if the network supports one or more of said security features, • exchange information with the network in order to enable the use of one or more of the above-mentioned supported security features in the communication, • carry out at least one of the one or more of the supported security features in the communication with the network.

摘要： The present invention relates to a 2G controlling entity (104) in a common 2G/3G network, wherein the common 2G/3G network comprises a common Core Network, CN, (102) connected to the 2G controlling entity (104) further 5 connected to dual mode mobile stations and to a 3G controlling entity (106) further connected to dual mode mobile stations, the 2G controlling entity (104) comprises means for applying (301) a 3G camping strategy and means for receiving a service request for a service at least supported by the 2G network performed by a dual mode mobile station. The 2G controlling entity 10 (104) comprises means for instructing (303) the dual mode mobile station when connected to the 2G network to perform cell reselection evaluation of 3G network cells (110) only when the 2G network (108) signal strength is below a predetermined threshold. The present invention also relates to a method and to a common 2G/3G network.
