摘要： IP applications may be hosted on processors other than the processor on which their associated routing entity is hosted by causing the routing context to be extended to the new processor and causing IP termination to occur at the new processor. Applications may define policies specifying packet attributes and actions to be taken on matching packets, so that packets matching the policy may be directed to a processor hosting the application rather than a processor hosting the routing entity. A steering policy manager may be implemented to receive policies from the applications, verify the policy format and uniqueness vis-à-vis previously implemented policies, and implement the policies by passing the policies to one or more steering policy agents. Filters may be programmed into the data plane or the control plane to cause IP termination to occur on the processor hosting the application.

摘要： A magnetic random access memory (MRAM) array and method for making the MRAM array are disclosed. The MRAM array includes magnetic storage cells, global word lines, magnetic word lines, read bit lines, selection devices, and write bit lines. Each magnetic word line has segments. Each segment is coupled with the global word line(s) such that each segment is separately selectable. Each segment is also coupled to a portion of the magnetic storage cells. The read bit lines are oriented at an angle with respect to the magnetic word lines. The read bit lines are coupled with the magnetic cells through the selection devices. The write bit lines are substantially parallel to the read bit lines. Preferably, the magnetic word lines include soft magnetic materials and are coupled to each magnetic storage cell through a thin, nonmagnetic layer. To reduce interference from currents in global word lines, the global word lines are also substantially parallel to the magnetic word lines.

The logic processing device, in one aspect, includes a phase adjustment circuit, ASIC, and configurable logic circuit (“CLC”) wherein the CLC can be an FPGA. While ASIC is able to perform a specific function in accordance with an ASIC clock domain, the CLC is capable of performing a programmable logic function in accordance with an FPGA clock domain. The phase adjustment circuit is used to automatically facilitate a communication between the ASIC and the CLC in accordance with the ASIC clock domain and the FPGA clock domain.

摘要： OAM may be implemented at an intermediate node on a PBT trunk in an Ethernet network by causing OAM frames to be addressed to the PBT trunk endpoint but causing the OAM frames to carry an indicia (Ether-type, OpCode, TLV value or combination of these and other fields) that the OAM frames are intended to be used for intermediate node OAM functions. The Ether-type, OpCode, and TLV values may be standardized values, or vendor specific values such as OpCode=51 or TLV=31 may be used. Addressing the OAM frames to the PBT trunk end point enables the OAM frames to follow the PBT trunk through the network. The OAM indicia signals to the intermediate nodes that the OAM frames are intended to be used to perform an intermediate node OAM function. The OAM frames may contain reverse trunk information to prevent the intermediate nodes from being required to store correlation between forward and reverse PBT trunks.

摘要翻译： OAM可以通过使OAM帧被寻址到PBT中继端点而实现在以太网网络中的PBT中继的中间节点上，但是导致OAM帧携带标记（以太类型，OpCode，TLV值或这些的组合 和其他字段），OAM帧旨在用于中间节点OAM功能。 以太类型，OpCode和TLV值可以是标准化值，或者可以使用诸如OpCode = 51或TLV = 31的供应商特定值。 将OAM帧寻址到PBT中继端点使得OAM帧能够通过网络跟随PBT中继。 OAM标记向中间节点发信号通知OAM帧旨在用于执行中间节点OAM功能。 OAM帧可能包含反向中继信息，以防止中间节点需要存储正向和反向PBT中继线之间的相关性。
