A method, system and program for preventing intrusion in a communications network. A source node initiates a request for network services, such as session establishment, database access, or application access. Known network resources and authorized user information is stored in a database at a network portal along with access policy rules that are device and user dependent. Identification of the source node is required before the source node can construct a transformed packet header that is included with a synchronization packet before transmission to a destination node. An appliance or firewall in the communications network receives and authenticates the synchronization packet before releasing the packet to its, intended destination. The authentication process includes verification of the access policy associated with the source node. Once received at the destination node, the transformed packet header is reformed by extracting a key index value. The extracted key index is subsequently used to transform the packet header in the response transmitted to the source node.

The method comprises: a) extracting the supper link from the instant communication message; b) getting the webpage corresponding to the extracted supper link; c) extracting the content abstract information from said webpage; d) displaying said content abstract information. The apparatus thereof comprises: a supper link extracted module, a webpage obtained module and a display module. By the invention, users can know the webpage content corresponding to the supper link without starting the browser while using the instant communication tool to make instant communication.

A method and system for monitoring UDP communications and for preventing unauthorized UDP communications within a computer network. A method for managing access to a resource comprises assigning a unique user identifier to each authorized user, upon initiation of a UDP communication initialed by a specific authorized user for access to a specific resource, appending the unique user identifier of the specific authorized user to each UDP packet of the UDP communication, intercepting the plurality of UDP packets within the computer network, extracting the unique user identifier from each UDP packet to identify the specific authorized user associated with the respective UDP packet, and allowing each respective UDP packet to reach the specific resource as a function of the unique user identifier extracted from the respective UDP packet.

The invention discloses a bovine left abomasal displacement operative reduction apparatus with a reduction needle transmitting range setting function. The bovine left abomasal displacement operative reduction apparatus comprises a reduction needle transmitting device and a reduction needle with a line binding hole. The outer edge of the reduction needle transmitting device is smooth, the reduction needle transmitting device comprises a transmitting tube, an ejection portion and a trigger, the ejection portion is positioned at the rear of the transmitting tube and is communicated with the transmitting tube, the reduction needle is straight, the rear end of the reduction needle is arranged in the ejection portion, the other portion of the reduction needle is positioned in the transmitting tube, and the line binding hole is positioned on a needle body in the transmitting tube; the reduction needle transmitting device is further provide with a suture line position lock, and the length of a suture line is locked by the suture line position lock, so that the transmitting range of the reduction needle can be controlled. The bovine left abomasal displacement operative reduction apparatus has the advantages that the traditional double-side incision operation can be simplified onto single-side incision operation, so that the survival probability of seriously ill cattle can be effectively increased; the reduction needle further can be effectively protected, the transmitting distance of the reduction needle can be controlled, accordingly, accidents can be reduced, and the success rate of operation can be increased.
