摘要： A method of adjusting fields of a datagram in the handling of the datagram in a network device may comprising receiving a datagram, with the datagram having at least module identifier fields and port identifier fields, at a port of a network device, adding or subtracting an offset value to at least one of the module identifier fields and at least one of the port identifier fields of the datagram based on data registers in the network device, and forwarding the datagram to a legacy device based on the module and port identifier fields of the datagram. A size of each of the module identifier fields and the port identifier fields handled by the legacy device may be smaller than a size of the module identifier fields and port identifier fields handled by the network device.

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： A method of forwarding data in a network switch fabric is disclosed. An incoming data packet is received at a first port of the fabric and a first packet portion, less than a full packet length, is read to determine particular packet information, the particular packet information including a source address and a destination address. An egress port bitmap is determined based on a lookup in a forwarding table and it is determined if the destination address belongs to a trunk group of trunked ports. The incoming data packet is forwarded based on the egress port bitmap, when the destination address does not belong to the trunk group. When the destination address does belong to the trunk group, a particular trunked port of the trunk group is determined and the incoming data packet is forwarded thereto. More specifically, the particular trunked port of the trunk group may be determined by calculating a hash value based on the source address and the destination value and selecting the particular trunked port based on the hash value. Additionally, a class of service for the incoming data packet is also determined from the particular packet information and a priority for forwarding is set based on the class of service.

摘要翻译： 公开了一种在网络交换结构中转发数据的方法。 在结构的第一端口处接收输入数据分组，并且读取小于全分组长度的第一分组部分以确定特定分组信息，所述特定分组信息包括源地址和目的地地址。 基于转发表中的查找来确定出口端口位图，并且确定目的地址是否属于中继端口的中继线群组。 输入的数据包根据出口端口位图转发，当目的地址不属于中继线群组时。 当目的地址属于中继组时，确定中继组的特定中继端口，并将传入的数据包转发到其中。 更具体地，可以通过基于源地址和目的地值计算哈希值并基于哈希值来选择特定中继端口来确定中继线群组的特定中继端口。 此外，还根据特定分组信息确定用于输入数据分组的一类服务，并且基于服务等级设置用于转发的优先级。

摘要： One or more embodiments of the invention set forth techniques to perform integer division using addition operations in order to provide address translation capabilities to a processor. The processor supports a memory that maintains checksum information such that address requests received by the processor need to be translated to a checksum address and an actual data address that accounts for use of portions of the memory to store checksum information. Once the checksum address and the actual data address are computed, the processor can confirm the integrity of the data stored in the actual data address and correct any errors if need be, based on the checksum information stored in the checksum address.
