    Abstract: An Ethernet switch has at least one ingress/egress port which is operable in two modes, in a first mode as a GE port and in a second mode as a plurality of FE ports. The port has 8 MAC interfaces each of which is capable of receiving/transmitting FE packets, and at least one of the MAC interfaces can be configured to receive/transmit GE packets. Thus, the port has two modes of operation. The port further includes receive and transmit modules which receive GE and FE packets from, and transmit GE and FE packets to, the interfaces.

    Abstract: A method of comparing unmasked bits of an N-bit data key to an N-bit Rule includes dividing the key into C-bit chunks. Each of the chunks is used as an 5 address to extract from memories 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34, 41, 42, 43, 44. The memory is preprepared, such that the data stored in the address corresponding to that chunk of the key is 1 or O according to whether a bitwise comparison of that chunk of the data key with the mask is equal to a bitwise comparison of that chunk of the mask and rule. This extracted bit therefore indicates whether the rule is obeyed for that chunk of the data key. The N/C extracted bits for each rule are compared, to determine if the rule is obeyed for the entire data key.

    Abstract translation: 将N位数据密钥的未屏蔽位与N位规则进行比较的方法包括将该密钥分成C位块。 每个块被用作从存储器12,13,14,21,22,23,24,31,32,33,34,41,42,43,44中提取的5地址。存储器是预备的，诸如 根据该数据密钥与掩码的该块的按位比较是否等于该掩码和规则的该块的按位比较，存储在与该密钥的该块相对应的地址中的数据是1或0。 因此，提取的比特指示是否遵守该数据密钥块的规则。 比较每个规则的N / C提取比特，以确定是否遵守整个数据密钥的规则。

    Abstract: A parser system is arranged to receive a data stream (1) having interleaved sections derived from a plurality of different packets, and to extract data from each section as it arrives. The parser system has a scanning section which receives information about each of the sections of data defining which packet it relates to, and employs this information and the properties of the data stream, to identify the locations of layer (2), layer (3) and layer (4) data. This information is passed to parser units (7), (9) which extract data based on this data and also offsets. The offsets for the parser (7) are stored in user-programmable registers (9).

    Abstract: An Ethernet switch has at least one ingress/egress port 1 which is operable in two modes, in a first mode as a GE port and in a second mode as a plurality of FE ports. The port has 8 MAC interfaces 3 each of which is capable of receiving/transmitting FE packets, and at least one of the MAC interfaces can be configured to receive/transmit GE packets. Thus, the port has two modes of operation. The port further includes receive and transmit modules 5, 7 which receive GE and FE packets from, and transmit GE and FE packets to, the interfaces. If there are 8 such ports in the Ethernet switch, then by switching different numbers of the ports between the two modes, the switch may operate in 9 different modes: as 8 GE ports, 7 GE ports and 8 FE ports, 2 GE ports and 48 FE ports, 1 GE port and 56 FE ports, or simply as 64 FE ports.
