Abstract: A system and method for endpoint handoff in a hybrid peer-to-peer networking environment are provided. In one example, the method includes logging into the peer-to-peer network by a first endpoint. The first endpoint directly notifies a second endpoint that the second endpoint is to transfer an active communication session existing between the second endpoint and a third endpoint from the second endpoint to the first endpoint. The first endpoint receives session parameters associated with the active communication session directly from the second endpoint and directly notifies the third endpoint that the first endpoint is online. The first endpoint then re-establishes the active communication session with the third endpoint using the session parameters.

Abstract: Identifying network devices having specified traits using a multi-level hierarchical data structure. Bloom filters representing traits of network devices are received and their bit vectors are decomposed into successive bytes. For each byte except the last one, memory for storing a pointer to memory on the next level is allocated on the level corresponding to the byte. The pointer storage is labeled by the value of the next byte. A pointer to the allocated memory is stored in the pointer storage on the previous level that was labeled by the value of the current byte. For the last byte, memory for storing references to network devices is allocated on the last level. A pointer to the allocated memory is stored in the pointer storage on the second-to-last level that was labeled by the value of the last byte. A reference to the network device is stored in the allocated memory.

The method comprises receiving an indication for a preference for an approximate number of content to be delivered during an indicated time period; assigning a first score to the first content according to one or more factors, in response to receiving a first content at a first point in time during the first time period; delivering the first content, in response to determining that the first score is above a first dynamically calculated threshold, wherein the first dynamically calculated threshold is calculated based on: t: time of arrival of the first content, k(t): number of contents that has been delivered until the first point in time, K: the approximate number of events to be delivered during the indicated time period, and F: a distribution function calculated based on prior history of the content delivered.

Abstract: A method is provided in one example embodiment and includes communicating content to a content receiver, where a first portion of the content has a first drop priority. The method also includes determining a buffer status for a buffer at the content receiver, and adjusting the first drop priority to a second drop priority for a second portion of the content based on the buffer status. In more particular embodiments, the second drop priority can be higher than the first drop priority of the first portion of the content if the buffer is full or above a threshold. Also, the second drop priority can be lower than the first drop priority of the first portion of the content if content in the buffer has not started to render.

Abstract: A test system for a distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer (LB) nodes, which in turn distribute the packet flows among multiple server nodes. The test system includes message bus technology that enables the distributed load balancer to be run in a single process without requiring load balancing code to be deployed to multiple hosts in a production network. The message bus technology may be implemented in message bus layers of the test system to simulate network segments. The message bus functionality hooks into the IP tables at the kernel level, intercepts packets, and sends the packets up into the message bus process for routing.
