摘要： The present disclosure describes data transmission in a packet transport network (PTN). A multiple stack device facilitates data transmission between a first edge device of a first PTN technology and a second edge device of a second PTN technology. After receiving a first packet of the first PTN technology from the first edge device, the multiple stack device identifies a first connection with the first edge device according to information of the first packet and identifies a second connection with the second edge device from the first connection based on a relationship between the first connection and the second connection. The first packet is de-encapsulated and re-encapsulated into a second packet of the second PTN technology according to the second connection. The second packet is then forwarded to the second edge device via the second connection.

摘要： The present invention discloses a packet processing method, which applies to a high-performance and scalable flow processing system architecture. The service board performs security processing for packets received from external devices by using the firewall function before sending them to the main CPU; similarly, the service board also performs security processing for packets sent from the main CPU by using the firewall function before the main CPU sends them to external devices. The methods of the present invention utilize high performance and good scalability of the new architecture. In a network with heavy and high-speed traffic, the service board performs security processing for packets by using the firewall function and then transmits the valid packets to the main CPU. Thus, the main CPU is protected by the firewall function against attack packets.

摘要： A data packet access control apparatus and a data packet access control method are disclosed. RAM resources in a data packet processing chip are used to implement a Bypass FIFO. The Bypass FIFO is used as a first-level cache for small amount of data, and an external RAM of the data packet processing chip is used as a second-level cache for large amount of data. In this way, some data packets are read and written within the chip and not all data packets have to be read and written through the external RAM. A data packet reading/writing operation may be performed to the external RAM by a BANK interleave mode.
