摘要： Gas turbine engines and methods for cooling components thereof with mid-impeller bleed (MIB) cooling air having a pressure are provided. The gas turbine engine has a compressor comprising an impeller body and an impeller shroud at least partially surrounding the impeller body. The impeller shroud has a plurality of MIB openings disposed therein. At least one edge treatment is provided thereto. The edge treatment substantially preserves pressure of the cooling air during entrance into and discharge out of the MIB opening. The plurality of MIB openings may be extended MIB openings in a thickened impeller shroud. The centerline of the MIB openings may be oriented to be substantially aligned with an averaged local absolute flow velocity vector of the cooling air at the inlet section of the MIB opening in order to extract cooling air in a direction that has a vector component in a tangential, an axial, and a radial flow direction.

摘要： An impeller or axial stage compressor disk backface shroud for use with a gas turbine engine is disclosed. The backface shroud includes, but is not limited to, a substantially funnel shaped body having a surface. The substantially funnel shaped body is configured to be statically mounted to the gas turbine engine substantially coaxially with the impeller or axial stage compressor disk. The surface and a backface of the impeller or axial stage compressor disk form a cavity that guides an airflow portion to a turbine when the substantially funnel shaped body is mounted coaxially with the impeller or axial stage compressor disk and axially spaced apart therefrom. The airflow portion has a tangential velocity and a recessed groove in the surface of the backface shroud is oriented generally transversely to the tangential velocity to at least partially interfere with the airflow portion, thus affecting static pressure in the cavity.

摘要： A translation agent adapts DOCSIS information, primarily QoS information, for transmission over a PON. The agent places into an IP address field of a DHCP message the MAC address of an ONU associated with a CPE device attempting to register with a CMTS. The translation agent intercepts DHCP reply messages from the DHCP server using the MAC address of the ONU. The translation agent extracts information, including an IP address of the client CPE assigned by the DHCP server. The agent downloads a configuration file for the CPE device using the configuration filename and configuration file server contained in a DHCP reply message. Information contained in the configuration file is converted from content in a format used by DOCSIS, to content in a format used by PON devices. The translated content includes QoS parameters, functions related to which are controlled at the ONU by an OLT coupled to the CMTS.
摘要翻译：翻译代理调整DOCSIS信息，主要是通过PON传输QoS信息。代理将DHCP消息的IP地址字段放置在与尝试向CMTS注册的CPE设备相关联的ONU的MAC地址。翻译代理使用ONU的MAC地址拦截来自DHCP服务器的DHCP应答消息。翻译代理提取信息，包括由DHCP服务器分配的客户端CPE的IP地址。代理使用DHCP回复消息中包含的配置文件和配置文件服务器下载CPE设备的配置文件。将配置文件中包含的信息从DOCSIS使用的格式的内容转换为PON设备使用的格式的内容。翻译的内容包括QoS参数，与其相关的功能由耦合到CMTS的OLT在ONU处控制。

摘要： A subscriber login server is used for managing a subscriber login session. The login server is associated with a DHCP server for configuring a premise equipment device and operator-managed device. A subscriber login client at the premise equipment device securely communicates login username and password identifiers to the subscriber login server without using PPP technology. The login server retrieves matching identifiers from a RADIUS server and authorizes service with messages to the DHCP server and the CMTS.The login client can emulate a PPP login client so that a user's interface is similar to a PPPoE client. However, a layer-3 CMTS can be used instead of a layer-2 CMTS. In addition, subscriber authentication and accounting using RADIUS are preserved, positive network access control at the CMTS is maintained, and native IP traffic is routed or switched for maximum performance and QoS treatment.
摘要翻译：登录客户端可以模拟PPP登录客户端，使用户的界面类似于PPPoE客户端。然而，可以使用第3层CMTS而不是第2层CMTS。另外，保留了使用RADIUS的用户认证和计费，保持了CMTS的正确的网络访问控制，本地IP流量被路由或切换，以实现最佳性能和QoS处理。

摘要： Bandwidth is assigned to subscribers of a data network by applying logic of one or more network devices to sample bits of information communicated over a network communication medium to identify if there is a network congestion condition or an extremely lightly loaded condition. The maximum bandwidth assigned to a subscriber is below a normative maximum bandwidth assigned to the subscriber if the network is congested and the logic of the one or more network devices identifies the subscriber as a heavy bandwidth user. The maximum bandwidth assigned to a subscriber is above the normative maximum bandwidth if the network is extremely lightly loaded and the subscriber is a heavy bandwidth user.
摘要翻译：通过将一个或多个网络设备的逻辑应用于采样通过网络通信介质传送的信息比特来识别是否存在网络拥塞状况或极轻负载的条件，将带宽分配给数据网络的订户。如果网络拥塞，并且一个或多个网络设备的逻辑将用户识别为重带宽用户，则分配给用户的最大带宽低于分配给用户的规范性最大带宽。分配给用户的最大带宽高于标准最大带宽，如果网络极度负载且用户是重带宽用户。
