When forming an L2VPN, each VPN server is required to decrypt data received from a VPN client using the source VPN client key and encrypt the data using the destination VPN client key. The loads of the encrypting and decrypting processings are high, thereby the VPN server through-put is lowered. In order to solve the above problem, according to the present invention, the destination address of an IP packet sent from the VPN client is used as a multicast address, then data is encrypted according to the security association of the multicast address distributed from the VPN server. The encrypted IP packet is encapsulated with the IP address of the VPN server and sent to the VPN server. Receiving this IP packet, the VPN server determines the destination VPN client according to the multicast address of the encapsulated IP packet, then encapsulated with the IP address of the destination VPN client and sent to the VPN client.
摘要:
A fluoro rubber composition which is able to make both a high tensile strength and a high elongation at break after vulcanization compatible with each other and from which favorable mechanical characteristics are obtained even in a high-temperature environment; and a bladder for tire fabrication, which is manufactured using the same are provided. The fluoro rubber composition includes a rubber component containing a fluoro rubber and carbon black, wherein in a dynamic viscoelasticity test of an unvulcanized rubber by a rubber process analyzer (RPA) (measurement temperature: 100° C., measurement frequency: 1 Hz), a difference δGA′ (G′(1%)−G′(100%)) between a shear modulus G′ (1%) at the time of a dynamic strain of 1% and a shear modulus G′ (100%) at the time of a dynamic strain of 100% is 120 kPa or more and not more than 3,000 kPa.
摘要:
A base station accommodation server can appropriately set a location registration area according to an installation location of a femto base station. The base station accommodation server is coupled to a location management server accommodating at least one first base station coupled to a first communication network, and accommodates at least one second base station connected to a second communication network. The base station is configured to determine a location management group identifier of the second base station based on a location management group identifier of the first base station that is present at a location from which the second base station can receive the location management group identifier broadcast by the first base station.
摘要:
A communication system comprising a home server, an access gateway, and a policy server, wherein the policy server transmits, to the first access gateway, a link creation request for associating a communication path of the first terminal and a communication path of the second terminal; and the access gateway sets a fifth communication path which connects the first communication path and the third communication path upon receiving the link creation request, records information on the set fifth communication path in the communication path management information, and transmits the data from the first terminal via the first communication path to the second terminal via the fifth communication path and the third communication path based on the communication path management information.
摘要:
A relay gateway apparatus (HandOver-Gateway (HO-GW) is provided between heterogeneous access networks (a WiMAX access network and a UMB access network). The HO-GW performs conversion of a movement control signal (an Inter-Access Gateway (AGW) handover control signal) and relay of communication data. When the relay is performed, user data from a correspondent node (CN) reaches a wireless terminal (mobile node (MN)) through a host agent (HA) of a core network, an access router ASN-GW, the HO-GW, and a base station eBS.
摘要:
Provided is a wireless communication system, comprising: a base station providing communication by a plurality of communication methods; and a mobile node for communicating with the base station by the plurality of communication methods. The mobile node calculates a first distance between a wireless LAN access point and the mobile node; and judges whether the communication by the wireless LAN is possible by comparing the calculated first distance and a second distance that is a distance within which communication by a wireless LAN is available.

Security policy databases capable of being fast retrieved while securing sequentiality. An IPSec processing device of the present invention performs communications by encrypting IP packets exchanged between a first IP network and a second IP network. The IPSec processing device includes a security policy database that stores security policies. The security policy database includes first, second, and third security policy databases. The first and third security policy databases include a linear list structure, and the second security policy database includes a hash list structure. The IPSec processing device, when performing at least one of transmission and reception of the IP packet, retrieves a security policy in the order of the first, second, and third security policy databases.
摘要:
A session QoS control apparatus includes a session management database in which session management information per user terminal is stored, a user preference database in which user preference information representing the user state and QoS requirement associated with the identifier of a user communication terminal is stored, and a user communication terminal and router management database in which mapping between a user terminal and a network node to which the terminal is connected is stored. Upon receiving user session information, the apparatus analyses the user session information by referring to the session management and user preference databases and determines a QoS policy for the session between caller and callee terminals. From the user communication terminal and router management database, the apparatus retrieves a node on which the session QoS policy should be set and transmits a QoS command to the node to set the session QoS policy on the node.
