摘要： A preferred embodiment of the present invention includes a method and apparatus for allocating and using IP addresses in a network of client systems. More specifically, the present invention includes a router which monitors the assignments of IP addresses by a DHCP server. As each IP address is assigned, the router associates the assigned IP address with an trusted identifier which identifies the client system. Subsequently, if the router received a packet directed at the assigned IP address, the router forwards the packet to the client system having an trusted identifier associated with the destination address of the IP packet. Additionally, if the router receives a packet from a client system, it uses the trusted identifier of the client system to find IP addresses associated with the client system. If the source address of the IP packet is not included in the IP addresses associated with the client system, the packet is discarded.

摘要： A preferred embodiment of the present invention includes a method and apparatus for routing an IP packets in a network of client systems. The router forwards IP packets between the client systems and the server systems. More specifically, the router can be pre-configured to include one or more "routes." Each route is a mapping between an IP address and a client system. The router may also learn route from other routers and by analysis of IP packets. Preferably, the routes known by the router are included in a route table. The router also monitors DHCP assignment of IP addresses to client systems within the network. When the DHCP assignment of an IP address is detected, the router creates a new route that associates the newly assigned IP address and the corresponding client system. The new route is marked so that it may only be overwritten by a subsequent DHCP assignment. The router then updates the route table to include the new route and purges the route table of learned routes that have been invalidated by the new route. In this way, the present invention allows dynamically assigned IP addresses to override learned routes.

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： An extensible set of auxiliary services for objects in an object-oriented system. Every object in an object-oriented system is implemented by an associated object manager. Each object manager in the present invention has an associated object manager identifier that identifies the object manager. Each object manager in the system can optionally provide various auxiliary services for objects that the object manager implements. These auxiliary services are objects implemented by the object manager itself, or by another object manager. For a particular type of auxiliary service, different object managers may provide different auxiliary services. For example, two object managers may provide two different freeze-melt services. For each type of auxiliary service type, there is a well-known context in which auxiliary services of that type are associated with names. For each type of auxiliary service, there is also a well-known function that transforms an object manager identifier into a name. When a client of an object needs to access an auxiliary service for an object, the client first invokes an operation within the object that provides the object manager identifier for the object manager that manages the object. The client then passes the object manager identifier to the well-known function for the desired type of auxiliary service that transforms the object manager identifier into a name. The client resolves the transformed name within a well-known context for the type of auxiliary service desired to obtain a representation of the desired auxiliary service.

摘要： A secure naming model for objects in an object-oriented system, wherein names are bound to objects within context objects. The context objects are implemented by name servers, and clients request that a context object "resolve" the name for the object. The name server that implements the context returns a duplicate of the desired object. If a name resolution involves more than one name server, an assurance of security is provided by the first name server to the second name server.

摘要： A method for dynamic application tracing in virtual machine environments comprises receiving an instrumentation request that includes an identification of a probe point at which instrumentation code is to be inserted within an application. The method may further comprise making a determination whether the instrumentation code meets one or more acceptance criteria. If the instrumentation code is found to be acceptable, the method may further comprise inserting the instrumentation code at the probe point within the application while the application is executing within a virtual machine, and obtaining information indicative of application state from an execution of the instrumentation code when the probe point is reached during application execution.

摘要： Methods and systems are provided for processing a cache. A candidate object is identified for updating. A fresh object corresponding to the candidate object is obtained if it is determined that a newer version of the candidate object is available. A destination buffer is selected from a group of primary and non-primary buffers based on an amount of available space in a primary buffer. The fresh object is stored in the destination buffer.

摘要： An apparatus and method for creating and maintaining a cyclic or circular buffer are implemented using logical blocks corresponding to the physical blocks of the buffer. The logical blocks are mapped to the physical blocks of the cyclic buffer, and are used to create an index table for the buffer. Each entry in the index table corresponds to one or more blocks in the buffer, and has a logical block number respectively associated with a buffer block. When information from the buffer is accessed, the index table is consulted to determine if the requested information is stored in the buffer. If the information is stored in the buffer, the logical block number corresponding to the information is retrieved from the entry and translated into a corresponding physical block number. Using logical block numbers allows simple determination of whether the buffer block is valid, and how new or fresh the buffer block is without requiring a generation or cycle number.

摘要： Systems and methods are disclosed in which a computer system having main memory and persistent memory is caused to perform a method for caching related objects. The computer system receives a plurality of objects from an origin server and computes a hash value based on source information about an object. Then the computer system stores the object based on the hash value with other related objects. Additionally, a computer system consistent with the present invention may retrieve related objects from the cache by performing a batch read of related objects.
