摘要： Embodiments of the invention provide systems and methods for applying a patch or a change to a set of binary modules executing on and used by resources of a computing cluster while reducing the downtime of those resources. According to one embodiment, applying a patch to a plurality of binary modules on a computing cluster can comprise identifying resources on one or more of a plurality of nodes of the cluster. Additionally, each of the plurality of binary modules on one or more of the nodes of the cluster can be identified. A graph can be generated logically representing the cluster. Groups within the binary modules and resources can be identified based on the graph. Patches can be applied to the binary modules based on the identified groups. Patching binary modules based on the identified groups can comprise patching all of the binary modules of an identified group together.

摘要： The present invention provides a method and apparatus of handling in-device co-existence interference in a wireless communication environment. In one embodiment, a method includes detecting in-device co-existence interference between a LTE module and an ISM module in user equipment. The method further includes identifying subframes and corresponding HARQ processes in a set of subframes allocated to the LTE module which are affected by the ISM module operation. Additionally, the method includes reserving the remaining subframes and corresponding HARQ processes in the set of subframes for the LTE module operation. Furthermore, the method includes indicating to a base station that the remaining subframes and the corresponding HARQ processes are reserved for the LTE module operation to resolve the in-device co-existence interference. Moreover, the method includes receiving scheduling pattern indicating subframes and corresponding HARQ processes reserved for the LTE operation or derived DRX parameters from the base station based on the indication.

摘要： One embodiment of the present invention provides a computing system. The switch includes a discovery module, a device management module, and a logical group management module. The discovery module constructs a multicast query message for a first multicast group to which the computing system is registered. The device management module extracts information about a remote switch from a query response message from the remote switch and constructs a client database, wherein a first entry in the client database contains the information extracted from the query response message. The logical group management module associates the remote switch with a second multicast group.

摘要： A routing system utilizes a layer 2 switch interconnecting several routers to intelligently forward multicast packets throughout an interne exchange carrying multicast content. The layer 2 switch performs protocol snooping to extract a lookup key that is based on network layer protocol information. The lookup key is uniquely formulated to support either shared or explicit source distribution trees. The lookup key is used to query a forwarding memory that returns an outgoing port index. The outgoing port index points to one or more outgoing ports that are eligible to receive the multicast packet. The outgoing ports are also connected to the neighboring device(s) that are designated to receive the multicast packet. The routing system also supports real time maintenance and updating of the forwarding memory based on the periodic exchange of control messages. The routing system is configured to support PIM routers operating in PIM SM or PIM SSM modes. However, the routing system can also support other multicast protocols and/or standards.

摘要： A system and method that provides for using source IP addresses and MAC addresses in a network to provide security against attempts by users of the network to use false source IP addresses in data packets. The system and method provide for analyzing MAC addresses and source IP addresses at the datalink (layer 2) level, and to use the information derived from such analysis to block access through a port where a host device is using a false, or spoofed, source IP address in transmitted data packets. Further, the system and method provide for validating initially learned source IP addresses, and for determining whether the number of unsuccessful attempts to validate new source IP addresses exceeds a threshold level, and where the number does exceed the threshold number the system and method can provide for operation in a possible attack mode.

The discovery module determines local switch-specific information associated with a switch based on a discovery response packet. The high-availability management module determines remote switch-specific information about the same switch with respect to a remote computing system. The controlling module determines whether the computing system is to manage the switch based on a metric derived from the local and remote switch-specific information.

摘要： Solutions are provided that allow a network device to apply flow control on the MAC layer while taking into account the priority of the frame of traffic. This may be accomplished by generating a frame indicating that traffic flow should be paused, while utilizing a new opcode value, or alternatively by utilizing a new type/length value (possibly combined with a new opcode value). A receiving device may then examine the fields of the frame to determine whether it should use priority-based pausing, and then examine other fields to determine which priority-levels to pause and for how long. This allows for improved efficiency in flow control on the MAC layer.
摘要翻译：提供的解决方案允许网络设备在考虑到流量帧的优先级的情况下对MAC层应用流量控制。这可以通过生成指示业务流应该被暂停，同时利用新的操作码值，或者通过利用新的类型/长度值（可能与新的操作码值组合）来实现。然后，接收设备可以检查帧的字段以确定它是否应该使用基于优先级的暂停，然后检查其他字段以确定要暂停的优先级等级以及多长时间。这样可以提高MAC层的流量控制效率。

摘要： Methods are provided for efficiently storing data to a data storage device or subsystem. The data storage device may be a Solid-State Device (SSD), and may be implemented as part of a RAID (Redundant Array of Independent Disks) or other subsystem. When existing data is read and updated, and must be re-stored, the data is assembled and stored as if it were new data, and is written in a sequential manner, instead of being written to the same storage location. A newer generation number distinguishes it from the previous version. If the storage subsystem employs data striping, stripe size may be matched with the size of a logical collection of data (e.g., an extent), so that each such logical collection of data is wholly stored on just device in the storage subsystem. Concurrent device access may be supported by concurrently writing substripes of data to each device/extent.
摘要翻译：提供了有效地将数据存储到数据存储设备或子系统的方法。数据存储设备可以是固态设备（SSD），并且可以被实现为RAID（独立磁盘的冗余阵列）或其他子系统的一部分。当现有数据被读取和更新并且必须被重新存储时，数据被组合和存储，就像它是新数据一样，并且以顺序的方式被写入，而不是被写入同一存储位置。较新版本的版本与之前的版本不同。如果存储子系统采用数据条带化，则条带大小可以与数据的逻辑集合（例如，扩展）的大小相匹配，使得每个这样的逻辑数据集合被完全存储在存储子系统中的设备上。可以通过将数据的同时写入每个设备/范围来支持并发设备访问。
