摘要： A method of handling a datagram in a network device is disclosed. The steps include receiving a datagram, with the datagram having multiple field values, at a port of a network device, parsing the received datagram to obtain the field values, applying the parsed field values to a Ternary Content Addressable Memory (TCAM), determining matches between the parsed field values and predetermined criteria in the TCAM, indexing into a policy table based on the determined matches to obtain an action entry and taking an action based on the obtained action entry.

摘要： Methods and systems for processing packets in data network using multistage classification are disclosed. An example method for processing packets includes receiving a data packet at a first processing stage and examining the packet at the first processing stage to determine a first attribute of the packet. Based on the first attribute, a first classification is assigned to the packet. In the example method, the packet and the first classification are communicated from the first processing stage to a second processing stage and the packet is examined at the second processing stage to determine a second attribute of the packet. Based on the second attribute, a second classification is assigned to the packet. The example method further includes processing the packet based on the first classification and the second classification.

摘要： A method of adjusting fields of a datagram in the handling of the datagram in a network device is disclosed. The method includes receiving a datagram, with the datagram having at least module identifier fields and port identifier fields, at a port of a network device, determining whether the received datagram is a unicast datagram, adjusting the module and port identifier fields of the datagram based on data registers in the network device when the received datagram is a unicast datagram and forwarding the datagram based on the module and port identifier fields of the datagram. The port of the network device is connected to a legacy device, where the legacy device has a reduced handling capacity when compared to the network device.

摘要： Various example embodiments are disclosed. According to an example embodiment, an apparatus may include a switch fabric. The switch fabric may be configured to assign packets to either a first flow set or a second flow set based on fields included in the packets. The switch fabric may also be configured to send a first packet from the first flow set to a first flow set destination via a first path. The switch fabric may also be configured to determine, based at least in part on delays of the first path and a second path, whether sending a second packet from the first flow set to the first flow set destination via a second path will result in the second packet reaching the first flow set destination after the first packet reaches the first flow set destination, the second packet having been received by the router after the first packet. The switch fabric may also be configured to send the second packet to the first flow set destination via the second path based at least in part on the determining that sending the second packet from the first flow set to the first flow set destination via a second path will result in the second packet reaching the first flow set destination after the first packet reaches the first flow set destination.
