摘要： A system and method for many-to-many failover and load balancing establishes a plurality of service groups for providing desired computing services. Each service group comprises a plurality of hosts, and each host within the service group is available to perform the computing services for which that group as a whole is responsible. Each host may belong to a plurality of service groups. Each operational host within a service group transmits periodic messages to each other host within the service group advising of the status of the transmitting host. A leader host evaluates the periodic messages and, where appropriate, dynamicall reassigns responsibility for particular computing services to a host within the group. The reassignment can be due either to failover or load balancing.

摘要： A data structure for dynamically associating a service dependent representation with a servant object at run time is used in a distributed object computing system that incorporates subcontracts. Subcontracts supply different functionalities to objects. The data structure exists before run time, and is used at run time to perform the dynamic association. An arrangement also exists at run time. The structure comprises a service representation class representing a single subcontract, a servant base class associated with servant objects created at run time, and a linking mechanism to form a run time link between the server rep class and a servant object at run time. The server rep class provides functionality unique to a subcontract. At run time, servant objects are instantiated from the servant base class or a more derived class. The servant object uses the functionality provided by a subcontract by way of the linking mechanism. An arrangement exists at run time for dynamically linking a servant object to a subcontract. Included are a servant object, a server rep object, and a pointer from the servant object to the server rep object. Methods and apparatus allow a servant object itself to initiate calls to deactivate itself, to determine remaining references to itself, to revoke itself, and to get an object reference for itself. A method creates a servant object that includes the above data structures and ability to call these functions.
摘要翻译：在运行时将服务依赖表示与服务对象动态关联的数据结构用于包含分包合同的分布式对象计算系统中。分包合同向对象提供不同的功能。数据结构存在于运行时间之前，并在运行时用于执行动态关联。运行时也存在一个安排。该结构包括表示单个分包合同的服务表示类，与在运行时创建的servant对象关联的servant基类，以及在运行时在服务器rep类和servant对象之间形成运行时链接的链接机制。服务器代表类提供独立于分包合同的功能。在运行时，servant对象从servant基类或更多派生类实例化。服务对象通过链接机制使用分包合作提供的功能。在运行时存在一个动态链接服务对象到分包合同的安排。包括一个servant对象，一个服务器rep对象和一个从servant对象到服务器rep对象的指针。方法和设备允许servant对象本身启动调用以停用自身，确定对其自身的剩余引用，撤销自身以及为其自身获取对象引用。一种方法创建一个包含上述数据结构和调用这些功能的能力的servant对象。

摘要： The present invention includes a method and apparatus for filtering IP packets based on events within a computer network. More specifically, the present invention includes a services management system, or SMS. The SMS manages network connections between a series of client systems and a router. An access network control server (ANCS) manages the configuration of the router. The SMS monitors activities or events that occur within the network. In response to these events, the SMS dynamically downloads filtering profiles to the ANCS. The ANCS then uses the downloaded filtering profiles to reconfigure the router. The router then uses the filtering rules to selectively discard or forward IP packets received from the client systems.

摘要： The invention provides solutions to the problems which are encountered by object oriented systems designers when attempting to implement schemes for object invocation and for argument passing in distributed systems wherein the arguments may be objects, and wherein the system supports a multiplicity of ORB-specific data formats, in ways which do not lock the object oriented base system into methods which may be difficult to change at a later time. Moreover, the invention disclosed describes a "Marshal Buffer mechanism" which contains methods for marshaling data for a specific ORB; a "Multi-ORB Marshaling system" which permits a Client Application and related stub to invoke an operation on a target object without any knowledge or concern about which ORB this target object uses or what data format the ORB requires for the arguments of the operation invoked; and a "Computer system for multi-ORB communication" comprising an ORB independent layer which contains Client Applications and stubs; an ORB dependent-OS independent layer which contains ORB dependent code/Subcontract code mechanisms as well as ORB specific Marshal Buffers for a multiplicity of ORBs; and an Operating System (OS) layer.

摘要： Data structures, methods and devices for reducing computing overhead associated with dispatching a distributed object invocation and improving the flexibility of the dispatch framework in a distributed client/server based computing system are disclosed. In one aspect of the invention, a request received on an end point in a transport layer is dispatched from the transport layer to a subcontract in a subcontract layer where the request is partially unmarshaled and dispatched from the subcontract to a skeleton function in a skeleton layer where a servant is invoked. In another aspect of the invention a method for initializing a subcontract which includes a skeleton dispatch function arranged to dispatch a received request to an appropriate skeleton after the subcontract has unmarshaled at least a portion of the received request involves registering the subcontract with at least one cluster end point registry, creating a subcontract meta object associated with the subcontract, and storing the subcontract meta object in a subcontract registry.

摘要： A method and apparatus for controlling access to services within a computer network is provided. More specifically, the present invention includes a services management system, or SMS. The SMS manages network connections between a series of client systems and a router. An access network control server (ANCS) manages the configuration of the router. For each network user, the SMS maintains a profile of filtering rules. When the user accesses the network, the SMS downloads the user's filtering profiles to the ANCS. The ANCS then uses the downloaded filtering profiles to reconfigure the router. The router then uses the filtering rules to selectively forward IP packets originating from the user's host system and directed at the network services.

摘要： A system and method provides dynamic and static type support for multiple definitions of individual types in a distributed object environment. Fully scoped object names incorporating prefixes are used to distinguish objects. The fully scoped names are used for both dynamic type determination through an interface repository and for statically compiled types in client and server stub routines. In the interface repository, a prefix naming context is provided for each root interface definition language context, allowing multiple definitions for objects with the same interface definition language object name, where each such definition resides in a separate prefix naming context. In one embodiment, the prefix naming contexts are defined by prefix interface definition objects. In another embodiment, the fully scoped object names are embedded by an interface definition language compiler in stub and skeleton code routines. RRS.
