Appl. No.:

10/322814

Inventors:

Brian Hassink - Cary NC, US
Matt Squire - Raleigh NC, US
Tim Zimmer - Durham NC, US

Assignee:

Horizon Technology Funding Company V LLC - Farmington CT

International Classification:

H04L 12/26
H04L 12/28

US Classification:

370225, 370252, 370392, 34082502

Abstract:

Faults are detected and recovered from in a multiprotocol label switching (MPLS) network by communicating packets between a first node and a second node in the MPLS network using a set of prioritized label switch path (LSP) pairs. A failure to receive a relatively constant rate of packets during a predetermined time interval is detected at the first node. Packets are sent from the first node to the second node using a backup LSP pair responsive to detecting the failure. Packets are then sent from the second node to the first node using a backup LSP pair responsive to receiving packets at the second node on the backup LSP pair.

International Classification:

H04L 12/823
H04L 12/851

Abstract:

The subject matter described herein relates to methods, systems, and computer readable media for discarding messages during a congestion event. One method includes registering a traffic congestion policy for handling traffic associated with an application during congestion. The method further includes determining a first congestion level associated with a congestion event. The method also includes determining message rates of messages associated with similar message priority values, wherein the message priority values are determined using the traffic congestion policy. The method further includes discarding a first message using the message rates, the first congestion level, and a message discard algorithm, wherein the message discard algorithm is determined using the traffic congestion policy.

H04L 12/873
H04L 12/54
H04L 12/825

Abstract:

According to one aspect, the disclosed subject matter describes herein a method that includes aggregating, by an egress function, message traffic directed to a target server entity from each of a plurality of ingress functions and procuring, by the egress function, dynamic update data that includes a message processing capacity threshold value associated with the target server entity and an aggregated message traffic rate corresponding to the message traffic received from the plurality of ingress functions. The method further includes sending the dynamic update data to each of the plurality of ingress functions and adjusting, by each of the ingress functions, an outgoing message traffic rate directed to the target server entity in accordance with the dynamic update data.

International Classification:

H04L 12/801
G06F 9/50

Abstract:

Methods, systems, and computer readable media for providing a workload balancer for balancing message traffic received over long-lived Diameter connections are disclosed. One exemplary workload balancer includes at least one connection front end processor for terminating Diameter connections with external nodes. The workload balancer further includes a plurality of Diameter back end processors for performing application or routing processing for the Diameter messages received over the Diameter connections. The at least one connection front end processor load shares Diameter messages received over existing Diameter connections among the back end processors.

Abstract:

Methods, systems, and computer readable media for network traffic regulation of multi-priority traffic in a telecommunications network are disclosed. According to one aspect, a method for regulation of multi-priority traffic in a telecommunications network includes, at a node for processing messages in a telecommunications network, receiving a message having an intended destination, determining a priority of the message, and obtaining, from a plurality of threshold values, each threshold value being associated with one of a plurality of message priorities, a threshold value that is associated with the determined priority. The number of messages that have been allowed during a current measurement period is determined, an action to perform on the message is selected based a relationship between the threshold value and the message count, and the selected action is performed. The method includes detecting a refresh condition, and, in response to detecting the refresh condition, starting a new measurement period.
