摘要： In one embodiment, in-band operations data included in packets being processed is used to signal among entities of a virtualized packet processing apparatus. Using in-band operations data provides insight on actual entities used in processing of the packet within the virtualized packet processing apparatus. The operations data in the packet is modified to signal a detected overload condition of an entity that participates in communicating the packet within the virtualized packet processing apparatus and/or applying a network service to the packet. An In-Situ Operations, Administration, and Maintenance (IOAM) header is used in one embodiment, with the IOAM header typically including a new Overload Flag to signal the detection of the overload condition. In response to the signaled overload condition, a load balancer is adjusted such that future packets are not distributed to the virtualized entity associated with the detected overload condition.

摘要： In one embodiment, a Segment Routing network node provides efficiencies in processing and communicating Internet Protocol packets in a network. An Internet Protocol (IP) packet, possibly a Segment Routing packet, is received by a node in a network, which updates the packet according to a corresponding Segment Routing Policy, that includes an ordered list of Segment Identifiers comprising, in first-to-last order, a first Segment Identifier followed by one or more subsequent Segment Identifiers. The updating of the packet includes setting the Destination Address to the first Segment Identifier, and adding said one or more subsequent Segment Identifiers, but not the first Segment Identifier, in a first Segment Routing Header. The updated packet is sent into the network without the first Segment Identifier being added to a Segment Routing Header in response to the Segment Routing Policy.

摘要： A Max Sessions Server (MSS) automatically detects hardware and communications failures. Upon detection, counters are adjusted accordingly to maintain an accurate count of users or groups of users on a system. A database of unique identifiers for each connection is maintained, where the unique identifier is a concatenation of a Network Access Server (NAS) and the connection's incoming NAS node number. If a user requests permission to log into the system, the MSS first checks the database to determine if the unique identifier is already logged in. If so, then a hardware or communications failure has occurred and the MSS must make the appropriate adjustments to the database and counter.

摘要： In one embodiment, a method for providing voice quality assurance is provided. The method determines voice information for an end point in a voice communication system. The voice information may be from an ingress microphone. The method determines if the voice quality is considered degraded based on an analysis of the voice information. For example, the voice information may indicate that it is distorted, too loud, too soft, is subject to an external noise, etc. Feedback information is determined if the voice quality is considered degraded where the feedback information designed to improve voice quality at an ingress point for a user speaking. The feedback information is then outputted at the end point to the user using the end point.

摘要： A multilevel coupled policer is configured to police packets using at least two policing levels, including a first-level of class policers and a second-level aggregate policer. The multilevel coupled policer is configured to share bandwidth of the aggregate policer among packet traffic corresponding to the class policers based on the packet traffic. The multilevel coupled policer is configured to apply a particular class policer corresponding to a particular packet to identify a tentative policing action. The multilevel coupled policer is configured to apply the second-level aggregate policer to the particular packet based on the identified the tentative policing action and a result of a comparison operation of the number of tokens in one or more token buckets associated with the second-level aggregate policer and the length of the particular packet in order to determine a final policing action for marking and/or applying to the particular packet.

摘要： Streams of packets are dynamically switched among dedicated and shared queues. For example, when a packet stream is in a maintenance mode (such as to keep a tunnel or packet stream associated with a server active) all packet traffic received over a packet stream is directed into the shared queue while the packet stream is not associated with one of the dedicated queues. In response to a detected change in the packet activity status of packet traffic (e.g., the establishment of a call or an increase in packet traffic, especially desirous of individualized quality of service) over a particular packet stream of the packet streams, the particular packet stream is associated with a particular group of dedicated queues such that at least non-control data traffic received over the particular packet stream is subsequently directed into the particular group of dedicated queues while the particular packet stream remains associated with the particular group of dedicated queues.
