Abstract: The invention relates to a thermal energy storage with at least one thermal energy storage volume. The thermal energy storage comprises at least one primary borehole extending from ground level to a first predetermined depth in a rock body; at least one set of secondary boreholes located around the at least one primary borehole; and at least an upper and a lower fracture plane extending in a radial and/or oblique plane from the at least one primary borehole towards adjacent secondary boreholes. At least one fracture plane permits a hydraulic flow between at least one of the secondary boreholes and the primary borehole. Each thermal energy storage volume is defined by one set of secondary boreholes and its upper and lower fracture planes. The set of secondary boreholes diverge away from the at least one primary borehole at each fractured plane level, without intersecting the at least one primary borehole.

Abstract: Embodiments of the present invention disclose a method, relay agent and system for acquiring an IP address in a network. According to the method, the relay agent configures multiple gateway IP addresses corresponding to a type of a client, adds the multiple gateway IP addresses to a DHCP Discover packet of the client, and sends the DHCP Discover packet to a DHCP server, so that the DHCP server allocates an IP address to the client, and sends a DHCP Offer packet to the client after determining that one gateway IP address in the multiple gateway IP addresses belongs to a same network segment as the allocated IP address, so that the DHCP server allocates the IP address to the client, thereby implementing that multiple IPs in different IP address segments are allocated to a same DHCP client type.

Abstract: The present invention provides a Layer 2 access method, device and system on a hybrid fiber-coaxial network, where the method includes: receiving a DHCP packet of a terminal device, extracting a source MAC address and a device type from the DHCP packet, and generating a correspondence between the source MAC address and an SVLAN according to a correspondence between the device type and the SVLAN; and when a data packet of the terminal device is received, extracting the source MAC address from the data packet, obtaining the corresponding SVLAN according to the stored correspondence between the MAC address and the SVLAN, and forwarding the data packet of the terminal device according to the corresponding SVLAN.

Abstract: A method and apparatus is provided for preventing the counterfeiting of a network-side Media Access Control (MAC) address. The method includes: receiving a message from a user equipment (UE) and resolving the message from the UE in order to obtain a MAC address of the UE; learning the MAC address of the UE if the MAC address of the UE is different from a known MAC address of a network-side equipment; learning the MAC address of the network-side equipment; and generating a MAC address learning table by utilizing the learned MAC address of the network-side equipment and setting the MAC address learning table to be a static address table, and/or filtering messages having source MAC addresses being the MAC address of the network-side equipment and from other user-side ports by utilizing the learned MAC address of the network-side equipment.

Abstract: Embodiments of the present invention provide a method and a system for implementing multicast using a slave block in DSL access technique. Several slave blocks are cascaded with a master block accessed to the DSL. The master block and slave block are respectively connected with DSL users via RTUs, and access an uplink via a network interface of the master block. The slave block is configured to support the IGMP proxy or the IGMP snooping so as to implement multicast function independently. This invention overcomes the shortcomings including the heavy burden on the master block, low efficiency and serious waste in bandwidth resulting from the fact that the operation of the slave block multicast member is implemented in the master block, thus increasing the efficiency of multicast and saving bandwidth of the master block.
