Abstract: The present disclosure relates to computer-implemented methods, software, and systems for identifying trends in the behavior of execution of services in a cloud platform environment and support alert triggering for expected outages prior their occurrence. Metrics data for performance of the cloud platform is continuously obtained. Based on evaluation of the obtained metrics data, the performance of the cloud platform is tracked over time to identify a trend in a performance of a first service on the cloud platform. The identified trend in the performance is compared with a current performance rate of the first service. Based on an evaluated difference between the current performance rate and the identified trend, the difference is classified into an issue-reporting level associated with a prediction for an outage at the first service. A notification for the trend is reported.

Abstract: Systems and techniques are described for a path maximum transmission unit (MTU) discovery method that allows the sender of IP packets to discover the MTU of packets that it is sending over a conduit to a given destination. The MTU is the largest packet that can be sent through the network along a path without requiring fragmentation. The path MTU discovery method actively probes each sending path of each conduit with fragmentation enabled to determine a current MTU and accordingly increase or decrease the conduit MTU. The path MTU discovery process is resilient to errors and supports retransmission if packets are lost in the discovery process. The path MTU discovery process is dynamically adjusted at a periodic rate to adjust to varying network conditions.

Abstract: Described embodiments improve the performance of a computer network via selectively forwarding packets to bypass quality of service (QoS) processing, avoiding processing delays during critical periods of high demand, increasing throughput and efficiency may be increased by sacrificing a small amount of QoS accuracy. QoS processing may be applied to a subset of packets of a flow or connection, referred to herein as “lazy” processing or lazy byte batching. Packets that bypass QoS processing may be immediately forwarded with the same QoS settings as packets of the flow for which QoS processing is applied, resulting in tremendous overhead savings with only minimal decline in accuracy. In case of backlog, packets may be collected together into an aggregated or ‘uber’ packet, with QoS processing applied based on a virtual size of the aggregated packet.

Abstract: A method of control Maximum Transmission Unit (MTU) reporting and discovery using AT commands is proposed. In communications networks, the MTU of a communication protocol of a layer is the size (in bytes or octets) of the largest protocol data unit that the layer can pass onwards. In an IP network, IP packets may be fragmented if the supported MTU size is smaller than the packet length. In accordance with one novel aspect, the packet data protocol (PDP) context of a packet data network (PDN) connection comprises MTU information. By introducing MTU information to the PDP contexts, TE can use AT commands to query MTU parameters from the network and thereby avoid fragmentation. TE can also use AT command to set MTU parameters and thereby control MTU discovery.

Abstract: A method is presented of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers. For each of the bearers, independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to designate as ‘green’ data packets that are conformant with a predetermined maximum Information Rate for the bearer. One or more data packets is buffered for up to a predetermined maximum ‘green’ buffer time, during which if transporting the data packet would not cause the maximum information rate of the bearer to be exceeded, the data packet is designated as a ‘green’ data packet. The data packets are forwarded for transporting over the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets that are not designated as ‘green’ data packets are discarded, so as not to be transported through the transport network.
