A method of blocking network attacks using information included in a packet, and an apparatus thereof are provided. The method includes: receiving a packet containing information on the packet including at least information on a source from which the packet is sent, and information on a destination to which the packet is sent; and extracting the information on the packet included in the packet, comparing the information with a predetermined access control condition, and blocking or passing the packet. By doing so, a packet being transferred with a routing header capable of bypassing a security device as in an Internet Protocol version 6 (IPv6) network can be appropriately blocked or passed. Accordingly, security problems caused by the routing header can be overcome, and as a result, usage of the routing header can be promoted. Also, since a routing header can be used for transmitting a packet along a desired path, the routing header can be widely used without security problems, and can ease network security concerns relating to IPv6 networks that are expected to come into increasingly wide use.

Provided is a method of generating and searching for a single ternary content addressable memory (TCAM) entry for range search and exact-match search. First, it is determined whether an entry to be added is a range search entry or an exact-match search entry. When the entry is the range search entry, a bit at a predetermined position in the upper m bits corresponding to a range represented by the entry is set to “1” and the remaining bits including lower n bits is set to a “don't care” bit x, based on a range table for representing position information of one of the upper m bits which is set to “1” in ranges. When the entry is the exact-match search entry, the upper m bits is set to “don't care” bit x and the lower n bits is set to the entry value. By generating and searching for a single TCAM entry for a range search and an exact-match search, a space for storing the TCAM entry can be optimized and efficiency thereof can be improved.

Disclosed herein is a concrete reinforcing material for improving the durability of a concrete structure. The concrete reinforcing material quickly penetrates deep into a concrete structure by simply applying the material onto the surface of a concrete structure in use and fills fine pores of the concrete structure through a sol-gel process by hydrolysis to reinforce the concrete structure and form a blocking layer, so that the concrete structure is protected from harmful substances, and at the same time, cracks are repaired, thus achieving integration of the concrete structure. Further disclosed is a process for preparing the concrete reinforcing material.

摘要:
Spatial information associated with an audio signal is encoded into a bitstream, which can be transmitted to a decoder or recorded to a storage media. The bitstream can include different syntax related to time, frequency and spatial domains. In some embodiments, the bitstream includes one or more data structures (e.g., frames) that contain ordered sets of slots for which parameters can be applied. The data structures can be fixed or variable. The data structure can include position information that can be used by a decoder to identify the correct slot for which a given parameter set is applied. The slot position information can be encoded with either a fixed number of bits or a variable number of bits based on the data structure type as indicated by the data structure type indicator.
