Abstract: In one embodiment, a global domain name system (DNS) server processes a DNS query based on an internal network policy. Upon receiving a DNS query that is associated with a source IP address, the global DNS server identifies a client subnet based on the DNS query. The client subnet is associated with an internal device on an internal network. The global DNS server selects an internal network policy from multiple predetermined policies based on the source IP address and the client subnet. The global DNS server then tailors one or more DNS resolution operations that generate a response to the DNS query based on the selected internal network policy. Advantageously, the client subnet provides the global DNS server with visibility into the internal network. Such visibility enables the global DNS server to apply policies selectively at the granularity of individual devices on the internal network.

The BIER devices can communicate with each other to pass a multicast join message to the BIER edge router that is indicated as being usable as the path to the mLDP-capable multicast source.

Abstract: Techniques and mechanisms for providing asynchronous web service calls in an on-demand services environment. In response to request from a remote client, a page is provided. The page has content including logic to retrieve information from a remote resource external to an on-demand services environment via at least one asynchronous web service call. A controller component of the page is loaded before rendering a response to the remote computing device. At least one web service call is sent to the remote resource with the controller component. A continuation object is returned with the controller component to release the first thread from waiting for a response to the web service call. The continuation object provides a label to be used when handling the response. The response to the web service call is received from the remote resource and processing is resumed with the continuation object.

The datapath daemon is a run-to-completion process that performs various data-plane packet-processing operations at the edge of the network. The datapath daemon dispatches packets to other processes or processing threads outside of the daemon by utilizing a user space network stack.

Abstract: A computer system for optimizing bandwidth usage within a cloud storage system identifies distinct requests to access a particular digital file. When the number of requests exceeds a threshold, the computer system queries a remote directory server for the particular digital file. The query system then receives, from the remote directory server, addresses to data blocks stored within multiple remote storage nodes. The system requests at least a portion of the addressed data blocks. Upon receiving the blocks, the system decodes the particular digital file from the portion of the addressed data blocks. The computer system then stores the decoded digital file within local memory and communicates the local-area network address to the remote directory server.

Abstract: The embodiments herein provide a fair, high speed and lightweight consensus mechanism for leader election in distributed systems using coupons. The consensus mechanism uses a leader election mechanism that is randomized in twin dimensions of space and time using the concept of a colliding random walk. A source node is enabled to generate left and right coupons in a quantum resistant manner for random walks. Two novel coupon processing mechanisms called Process Execution Time Synchronization (PETS) mechanism and Single Queue (SQ) mechanism are used to process the coupons and find matches. The use of PETS optimizes memory and time requirements while SQ is extremely fast and efficient to handle large volumes of coupons. Also, the coupon forwarding to neighbouring nodes is performed based on three algorithms namely Uniform, Delay and Adaptive Delay forward. These forwarding algorithms effect high fairness even in case of open networks.

Abstract: Techniques are disclosed herein for ensuring convergence of states for reliable message delivery in geographically distributed message queuing systems. The techniques include receiving a message at a local system, in which the message is associated with a new message topic.

A new message state corresponding to the message ID and the message topic is entered in a message state table, wherein the message state entry indicates a message state corresponding to the message. At least one CRDT object is recorded in a message queue. Thereafter, a list of subscribers including individual subscribers mapped to the new message topic is resolved from a message destinations object. The message is then delivered to at least one of the individual subscribers.
