Abstract: The size of a Jitter Absorption Buffer (JAB) 34 is automatically changed in response to changes in network conditions. The JAB size is changed based on the fullness of the JAB and the recent variations in JAB depth. Automatic adjustment allows for a balance of providing adequate correction for Packet Delay Variation (PDV) while avoiding unnecessary increases in Absolute Packet Delay (APD) from the prolonged use of an oversized JAB. This abstract is provided as a tool for those searching for patents, and not as a limitation on the scope of the claims.

Abstract: Packet communication systems, or networks, are commonly used for the conveyance of information for data applications. The receive rate of incoming packets varies as congestion in the network causes variation in the amount of time for a packet to traverse the network before being placed into the JAB (Jitter Absorption Buffer). The disclosure contains methods for calculating a real time measurement of PDV (Packet Delay Variation). This real time measurement is useful as a metric on the quality of the service provided by the network or as a trigger for dynamic adjustment of the operation of equipment to optimize for current network conditions. More specifically, the disclosure includes a method that uses variations in the buffer depth of the JAB to measure PDV. This abstract is provided as a tool for those searching for patents, and not as a limitation on the scope of the claims.

Abstract: Normal 802.3 Ethernet requires a tree topology. If a ring or a loop exists, then packets will be forwarded around the ring indefinitely. If the ring is broken, then there is no possibility of packets being propagated forever. This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that handles a unidirectional break in a communication link. This abstract is provided as an aid to those performing prior art searches and not a limitation on the scope of the claims.

Abstract: This invention relates to the field of packet communications. More particularly, this invention is a method and system for using a jitter absorption buffer to absorb propagation delay variation in packet arrival time. The invention uses a finite state machine with two or more sates, such as L (210), M (220), H (230), LR (215), MR (225), and HR (235). State transitions occur based on events such as overflow (3081, 3241, 352), underflow (3081, 3241, 35 4), half full (316, 336, 356), or time expired (328, 344). According to one embodiment, when the measured delay variation exceeds a threshold, the buffer size is hitlessly increased, and when it is below the threshold, the buffer size is hitlessly decreased._

Abstract: This invention allows Ethernet to run on a ring topology by introducing breaks between the nodes (Fig. 5). The system can also reconfigure its topology in order to recover from failures (1520). This is accomplished by placing intelligent nodes (500, 510, 520, & 530) on the ring that work together to virtually break and restore the ring.
