摘要:
Systems and related methods are described for handling one or more resource requests. A protocol engine receives a resource request in accordance with a prescribed protocol, and a classification engine determines a desired class of service for the request. An analysis engine optionally analyzes the request, and, responsive thereto, determines a desired sub-class of service for the request. A policy engine then allocates a resource to the request responsive to one or both of the desired class of service, and the desired sub-class of service.

Systems and methods are described for analyzing the content of resource requests. A tokenizer parses the resource request and derives a key therefrom. A database associates values of the key with categories of service. An association engine uses the key to obtain one or more matching entries from the database, and derive therefrom the desired category of service for the resource request. A cookie engine derives cookie information from a cookie located in the resource request. A session engine derives session information from a session identifier located in a handshake message associated with the resource request. The desired category of service, the cookie information, and the session information are each useful for allocating a resource to the resource request.

摘要:
A system and method of allocating a resource to a service request. Servers are virtually assigned through a hierarchy including groups of servers and super groups of the groups of servers. Each service request type is associated with a service index that determines both a super group and a load balancing policy for that service request type. A load balancing policy may be applied to select a group of servers among several server groups associated with the super group. Another load balancing policy is applied to the selected group of servers to select a server to handle the service request. The hierarchical data structure allows servers to be configured into overlappable, arbitrary subsets that can address service requests matching configured content rules. Load balancing policies can be selected by service request type.

A packet reassembly system includes a buffer for storing information elements included in one or more incoming packets, a memory for storing validity indicators corresponding to the information elements, a first logic circuit capable of setting the validity indicators based on the information elements stored in the buffer, and a second logic circuit capable of determining the contiguity of the information elements stored in the buffer based on the settings of the validity indicators.

A restrainer for connection to the belled end of a female pipe or fitting. The restrainer has a groove for receiving a compressed, snap-fit gripping ring, constructed from two or more rigid segments joined by elastomeric segments. The gripping ring has rows of teeth on its inner circumference, shaped so the spigot end of a male pipe can be inserted through the restrainer into the belled end of the female pipe. The gripping ring restrains the male pipe from moving in an opposite direction when the system is pressurized. The coupler can be connected to the female pipe in several ways: it can be threaded onto a threaded lip of the pipe; a projection formed on its outer diameter or its inner diameter can be snap-fit into on onto the end of the female pipe; or it can be welded or fused onto the outer end of the female pipe.

The automatic free wheeling hub assembly includes a housing or body secured to the vehicle's wheel hub. The vehicle's drive axle extends into and is mounted in the body and wheel hub. The free wheeling hub assembly includes a cylindrical axle hub located in the interior of the body and spline connected to the splined end of the drive axle. The axle hub is provided with an external toothed section or series of circumferentially spaced teeth. A tubular clutch ring is mounted in the body for axial movement and is provided with internal teeth for engagement with the disengagement from the series of teeth provided on the axle hub. Fluid actuating means are provided in the body including a movable member in the form of a diaphragm or piston connected to the clutch ring for axially moving same relative to said axle hub in response to the pressure or pressure differential from a fluid source such as vacuum to effect the engagement and disengagement of the matching teeth of the axle hub and clutch ring.
