摘要： One embodiment disclosed relates to a method for mirroring of select network traffic. A data packet is received by a network device. A determination is made as to whether a designated aspect of the packet matches a flagged entry in a look-up table on the network device. If a match is found, then copy of the packet is sent to an associated mirror destination. Another embodiment disclosed relates to a networking apparatus. The apparatus includes at least an operating system, a look-up table, and a mirroring engine. The operating system includes routines utilized to control the apparatus, and the look-up table includes selection information for mirror sources. The mirroring engine forwards copies of selected packets to a corresponding mirror destination. Another embodiment disclosed relates to a method of selecting packets to mirror that includes checking state information relating to the network traffic against dynamic mirroring criteria.

摘要： In an embodiment of the invention, a method and system for a per-port penalty queue system in a network device includes: selecting a state for a port in the network device; wherein the selected state comprises either a normal state or a restricted state; wherein the normal state permits a packet received at the port to be copied to a first queue; and wherein the restricted state causes the packet to be copied to a penalty queue which has lower priority than the first queue or causes the packet to not be copied to a queue. In another embodiment of the invention, a method and system permit using the port state for modifying a forwarding decision for a packet, so that the penalized packet will use a sub-optimal or less optimal routing path to the packet destination. In another embodiment of the invention, a method and system permit using the port state as a search key into an access control list (ACL) operation related to packet forwarding decisions or packet filtering decisions.
摘要翻译：在本发明的一个实施例中，网络设备中的每端口处理队列系统的方法和系统包括：为网络设备中的端口选择状态; 其中所述选择状态包括正常状态或限制状态; 其中所述正常状态允许在所述端口处接收到的分组被复制到第一队列; 并且其中所述受限状态使得所述分组被复制到具有比所述第一队列低的优先级的惩罚队列，或者使得所述分组不被复制到队列。在本发明的另一个实施例中，一种方法和系统允许使用端口状态来修改分组的转发决定，使得受惩罚的分组将使用到分组目的地的次优或不太优化的路由路径。在本发明的另一个实施例中，方法和系统允许将端口状态用作搜索关键字进入与分组转发决定或分组过滤决策相关的访问控制列表（ACL）操作。

摘要： One embodiment disclosed relates to a method for remote mirroring of network traffic. A data packet to be remotely mirrored is received by an entry device. The entry device is pre-configured with a destination Internet Protocol (IP) address to which to mirror the data packet. An IP header is generated and added to IP encapsulate the data packet. The IP header includes the aforementioned destination IP address. The IP-encapsulated packet is forwarded to an exit device associated with the destination IP address. Subsequently, the exit device may decapsulate the IP-encapsulated packet to reproduce the original data packet.

摘要： One embodiment disclosed relates to a method for remote mirroring of network traffic. A data packet to be remotely mirrored is received by an entry device. The entry device is pre-configured with a destination address to which to mirror the data packet. The packet to be mirrored is encrypted. An encapsulating header is generated and added to encapsulate the encrypted packet. The encapsulating header includes the aforementioned destination address. The encapsulated packet is forwarded to an exit device associated with the destination address, where the packet may be decapsulated, and then decrypted, before being sent out of a port. In another embodiment, the entry and exit devices are remotely configured with encryption and decryption keys, respectively.

摘要： A system for performing an input processing function on a data packet. The system has an input port to which a first processor is coupled, which determines an attribute of the data packet, and a memory coupled to the first processor having a number of queues. The data packet is assigned to one of the queues based upon the attribute determined, which may be an indicator of a priority characterizing said data packet. Input processing is thus performed in a fixed amount of time, deferring variable latency operations until after the input memory.
摘要翻译：一种用于在数据分组上执行输入处理功能的系统。系统具有耦合第一处理器的输入端口，其确定数据分组的属性，以及耦合到具有多个队列的第一处理器的存储器。基于确定的属性将数据分组分配给一个队列，其可以是表征所述数据分组的优先级的指示符。因此，以固定的时间量执行输入处理，推迟可变等待时间操作直到输入存储器之后。
