Abstract: In one embodiment, a device in a serial network de-multiplexes a stream of traffic in the serial network into a plurality of data streams. A particular one of the data streams is associated with a particular endpoint in the serial network.

The network node provides all of the media streams of the media session to a single service function instance to ensure that the media session is processed by the single service function.

The method includes obtaining, by a controller of an optical network, a baseline configuration that includes a traffic mode that uses a predetermined channel spacing of a plurality of channels in a frequency spectrum. The plurality of channels are used for transmitting optical signals on an optical link in the optical network.

The customer service interactions sessions involve a Customer Service Representative (CSR), engaged in a customer service interaction with a customer. First, customer service interaction sessions, at a contact center server, between the CSRs and the customers begin. Data streams from CSR computer(s) to customer computer(s) are sent. Other data streams from the customer computers are received. The data streams are analyzed by a supervisor recommendation engine. Based on the analysis, the supervisor recommendation engine generates a ranking of customer service interactions sessions that would benefit most from supervisor input.

Abstract: In one embodiment, a service that monitors a network obtains file characteristic data of a file stored on a first endpoint in the network. The service infers characteristics of encrypted content within encrypted traffic in the network between the first endpoint and a second endpoint, by applying a machine learning-based classifier to traffic data regarding the encrypted traffic session. The service compares the file characteristic data of the file to the inferred content characteristics of the encrypted content within the encrypted traffic, to detect the file within the encrypted traffic. The service enforces a network policy in the network, based on the detection of the file within the encrypted traffic.

Abstract: In one embodiment, a device divides groups of tuples of traffic characteristics of encrypted network traffic into different pairs of the characteristics. Each of the pairs has a corresponding two dimensional (2-D) feature subspace. The device discretizes the 2-D feature subspaces, to form a plurality of bins in each feature subspace. The device assigns the pairs of the traffic characteristics in a particular group of tuples to the bins in the discretized 2-D feature subspaces. The device forms, for each group of tuples, a vector representation of the group of tuples based on the bins in the discretized 2-D feature subspaces to which the pairs of the traffic characteristics from the group are assigned. The vector representations of the groups of tuples are of a fixed dimension. The device uses the vector representations of the groups of tuples to train a machine learning-based traffic classifier.

The supervisory device identifies a period of time associated with the predicted seasonal congestion on the particular link. The supervisory device initiates, in advance of the identified period of time, re-computation of equal-cost multi-path (ECMP) weights associated with the plurality of links that prevent occurrence of the predicted seasonal congestion on the particular link during the identified period of time.
