摘要： Support for priority and IP security packets, and other protocols at the network interface level and in conjunction with FIFO-based packet buffers is provided by allowing out of order processing of certain packets in the FIFO. The optimized character of FIFO for sequential transfer is maintained, while particular types of packets are processed out of order to achieve minimum latency and maximum data security in an intelligent network interface card (10). A buffer (15) stores data packets in an order of receipt. Logic is included in the network interface to transfer packets out of the buffer (15) according to the order of receipt, and according to the respective packet types so that packets having a particular packet type are transferred out of the order of receipt relative to packets having other packet types.

摘要： One embodiment provides a system for decrypting data frames in an Ethernet passive optical network (EPON). During operation, the system maintains a local cipher counter at a local node, and receives from a remote node a data frame which is encrypted based on a remote input block and a session key. The remote input block is constructed based on the remote cipher counter and a remote block counter. The system updates the local cipher counter based on a received field located in a preamble of the data frame, truncates the local cipher counter by discarding a number of least significant bits, and constructs for the received data frame a local input block based on the truncated local cipher counter, the received field, and a local block counter. The system then decrypts the data frame based on the local input block and the session key.

摘要： One embodiment of the present invention provides a system that decrypts downstream data in an Ethernet passive optical network (EPON). During operation, the system receives a data frame which is encrypted based on a remote input block and a session key, wherein the remote input block is constructed based on a remote cipher counter and a remote block counter. The system adjusts a local cipher counter based on a received checksum located in a preamble of the data frame, wherein the local cipher counter is substantially synchronized with the remote cipher counter. In addition, the system truncates the local cipher counter by discarding n least significant bits thereof. The system then constructs a local input block based on the truncated cipher counter and a local block counter for the received data frame. Next, the system decrypts the data frame based on the local input block and the session key.
摘要翻译：本发明的一个实施例提供一种解密以太网无源光网络（EPON）中的下游数据的系统。在操作期间，系统接收基于远程输入块和会话密钥加密的数据帧，其中基于远程密码计数器和远程块计数器构建远程输入块。该系统基于位于数据帧的前导码中的接收到的校验和来调整本地密码计数器，其中本地密码计数器基本上与远程密码计数器同步。此外，系统通过丢弃其最低有效位来截断本地密码计数器。然后，系统基于截断的密码计数器和接收到的数据帧的本地块计数器构建本地输入块。接下来，系统基于本地输入块和会话密钥来解密数据帧。
