摘要： A cayalyst precursor is produced by reacting V.sub.2 O.sub.4 with phosphoric acid in an organic solvent in the presence of a polyol. The catalyst precursor is calcined to obtain a catalyst having a high density, highly attrition-resistance and a large specific surface area and requiring only a low temperature for the oxidation of butane.

摘要： In a network having an L2SW in which uplink VLAN is set, a transfer delay of a voice call packet is prevented. In a process of establishing a session between terminals (5), a packet transfer device (1) stores information capable of specifying a sending terminal (5-1) and a receiving terminal (5-2) and a correspondence relation (user connection information) to a connection port into a table. A SIP message of a session control packet communicated between the terminals (5) is snooped, and a destination IP address, a transmission source IP address, a destination port number, a transmission source port number, a connection port etc. are stored into the table. In a case where an RTP packet as voice data is received after the session is established, the packet transfer device (1) performs a loopback transfer or transfers it to an uplink port in accordance with the table.

摘要： In a packet forwarding apparatus including first line interfaces accommodating user terminals, a second line interface connected to a communication node on a session management apparatus side, and a protocol processing unit for updating a connection management table and a header information table when a specific session control packet is received from one of the first line interfaces. Upon receiving a real-time packet from one of the first line interfaces, if a table entry corresponding to the header information of the received packet has been registered in the connection management table, the control unit routes the received packet to one of the first line interfaces after rewriting its header information based on the header information table, and if the table entry has not been registered, the control unit routes the received packet as it is to the second line interface.
