In some embodiments, it is determined that a primary node has been elected from among a plurality of nodes in a replica set of nodes. The primary node accepts and processes client data access requests. The replica set includes the primary node and other secondary nodes. The primary node receives client data access requests. The primary node assigns a data sequence number to each client data access request that mutates state in the order the client data access requests are received. The data sequence numbers include a linearized processing order that is to be followed by each of the nodes in the replica set. The primary node sends the mutating client data access requests including any corresponding data sequence numbers to the secondary nodes. The primary node receives, from a threshold number of secondary nodes, an acknowledgement indicating reception of the client data access request. The primary node commits the data mutating access request.

A technique for adaptively distributing a web server request in a system having a plurality of web servers is disclosed. In one embodiment, the technique is realized by first generating a web server request distribution function for each of the plurality of web servers based upon performance measures of each of the plurality of web servers, wherein each of the plurality of web servers is assigned a respective probability range based upon each respective web server request distribution function. A random probability number is then generated for a web server request. The particular probability range encompassing the random probability number is then determined so as to identify the corresponding web server to which the web server request is to be distributed.

Some embodiments provide a proprietary 64-bit consistent distribution scheme that preserves the efficiencies of CARP while providing a significantly more balanced distribution of requests that is on par with schemes reliant on computationally expensive cryptographic hashes. The scheme performs hashing of requested URLs and identifiers of available servers over a 64-bit space while optimizing the hashing to remove computationally expensive operations. Some embodiments provide a variant of the scheme to provide a differentiated distribution on the basis of one or more differentiating factors. A first variant utilizes load factor values to adjust the resulting hashes and to produce a first distribution of differentiated content that varies from a second distribution of undifferentiated content. A second variant identifies requests for differentiated content from requests for undifferentiated content and utilizes a first scheme to distribute the differentiated content and a second altered scheme to distribute the undifferentiated content.

Disclosed herein are system and methods of accessing resources in a computer network. An exemplary method may include (a) receiving into a networking device, from a first client device of a plurality of client devices, a request for a given resource (e.g., a file, directory, or metadata) assigned to a given file service (e.g., a file share service, file sync service, or file search service), (b) verifying that the first client device is allowed to access the given file service, (c) in response to verifying that the first client device is allowed to access the given file service, identifying a second client device having at least one stored resource assigned to the given file service, and (d) sending to the second client device an updated request for the given resource that includes a unique identifier of the at least one stored resource assigned to the given file service.

An approach for managing addition or deletion of nodes in a multicast or broadcast group, which avoids introducing a single point of failure at a group controller, certificate authority, or key distribution center, is disclosed. A central group controller utilizes a binary tree structure to generate and distribute session keys for the establishment of a secure multicast group among multiple user nodes. The central group controller is replicated in a plurality of other group controllers, interconnected in a network having a secure communication channel and connected to a load balancer. The secure communication channel is established using a public key exchange protocol. The load balancer distributes incoming join/leave requests to a master group controller. The master group controller processes the join or leave, generates a new group session key, and distributes the new group session key to all other group controller replicas. Each group controller is successively designated as master group controller in real time when a former master group controller crashes or relinquishes its master authority.

Workload is programmatically distributed across a set of execution resources. In a multithreaded server environment, response time to end users is improved while increasing the efficiency of software execution and resource usage. Execution time and wait/queued time are tracked, for various types of requests being serviced by a server. Multiple logical pools of threads are used to service these requests, and inbound requests are directed to a selected one of these pools such that requests of similar execution-time requirements are serviced by the threads in that pool. The number and size of thread pools may be adjusted programmatically, and the distribution calculation (i.e., determining which inbound requests should be assigned to which pools) is a programmatic determination. In preferred embodiments, only one of these variables is adjusted at a time, and the results are monitored to determine whether the effect was positive or negative. The disclosed techniques also apply to tracking and classifying requests by method name (and, optionally, parameters).

In a business system which allocates a request for one business application to one or more of the computer resources executing such business application, the computer resources are accommodated among the plurality of the business systems so that the load covered by each of the business systems is averaged out. The arbitration apparatus for resource allocation 101 calculates a margin rate for each business system by measuring load for respective business systems, and by calculating a ratio of the measured load and the allowable execution amount allowable under current constitution. When a computer resource 1241 which is not allocated to business system is found, this computer resource is allocated to the business system indicating low margin rate while if such computer resource 1241 is not found, the computer resource 1241 is reallocated by being released from the business system having high margin rate.

A method and apparatus for allocating bandwidth within a network domain. A centralized bandwidth broker maintains a link-level database including detailed flow data for individual links in a network domain and a path-level database including summarized flow data for individual paths in the network domain. The bandwidth broker determines bandwidth allocations at a path-level by allocating discrete amounts of bandwidth, termed quotas, based on flow requests. If a flow request cannot be satisfied by allocating quotas, then the bandwidth broker uses the link-level database to recover bandwidth from unused bandwidth by other paths on the same link in order to satisfy the flow request. In another embodiment of a bandwidth broker, the centralized bandwidth broker is replaced by a distributed bandwidth broker including a central bandwidth broker and one or more edge bandwidth brokers. An edge bandwidth broker conducts path-level allocations and requests or releases quotas from and to the central bandwidth broker. The central bandwidth broker conducts link-level allocations and allocates or de-allocates quotas to and from the path maintained by the edge bandwidth broker.

Provided is a device and method for scheduling uplink resources in a wireless communication system supporting VoIP. When its data rate is decreased, an MS notifies a BS of the rate decreased. When increasing its data rate, the MS requests resource allocation to the BS by transmitting a BR header or a CQICH codeword. Compared to the conventional ertPS in which the BS periodically allocates uplink resources to the MS irrespective of the state of the MS, the BS does not allocate uplink resources when the MS transitions form a talk-spurt period to a silence period. Therefore, resources consumption arising from unnecessary bandwidth allocation is reduced.
