World Wide Streams XStream optimization


Bell Labs has an opportunity for a student to join our Application Platforms and Software Systems research lab in Antwerp for an internship in the area of software development tools.

Mission World Wide Streams (WWS) – www.worldwidestreams.io - is research platform for real-time distributed information processing, supporting both event streams, as well multimedia stream processing. WWS comes with a stream processing language, XStream. XStream is based on Typescript and abstracts away the complexity of stream processing in order to ease rapid prototyping of stream processing applications. WWS targets applications that handle 1000s of stream. Currently XStream provides constructs that guide the compiler in generating efficient dataflow plan, but the user need to select these building blocks manually.

The task of the student is to develop an XStream code-rewrite tool that detect particular patterns in the code and guide the user in selecting the right constructs, so e.g. multiple related small streams can be grouped together for more efficient processing.

Key responsibilities - The student will survey existing technology for

State Management Infrastructure for Stream Processing

Type: InternshipDuration: 6 weeks to 3 months

Bell Labs has an opportunity for a student to join our Application Platforms and Software Systems research lab in Antwerp for an internship in the area of stateful stream processing.

MissionThe student will add system-wide state management support to a research stream processing platform currently being built at Nokia Bell Labs (www.worldwidestreams.io).

BackgroundMost of the core dataflow operators used in stream processing are stateful, i.e. they maintain internal variables (e.g. counters, maps, etc) and their outputs depend on both the incoming data items as well as the internal state of the operator. Examples include windowing operators, running aggregates, and streaming joins.

These operators typically keep their state information in local in-memory structures. Upon failure, however, the state information is lost.System-wide state management mitigates this problem by providing a uniform, efficient, and reliable storage infrastructure with a simple and well-defined API that can be used by operators to store and retrieve state information. Such state management infrastructure can, additionally, serve as a crucial building block for scaling up the stateful operators.

Key responsibilities - The student will survey the approaches adopted

by other stream processing platforms - Will design and implement his/her own

state management infrastructure - Integrate (and test) the final subsystem with

Nokia Bell Lab’s stream processing platform - Submit a final report and give a

presentation to the research team

in-memory databases is a plus - Language skills: a working proficiency of English - Communication skills: be able to fluently



Feasibility study of ReRAM for Processing-in-Memory in thephysical layer of communication systemsType: InternshipDuration: 8 weeks .

Mission/ General PurposeProcessing-in-Memory (PIM) architecture is seen as a promising solution to the traditional “memory wall” problem where the memory becomes bottleneck for the processor performance. The main idea behind PIM is to bring the processor logic closer to the memory as much as possible such that the latency in accessing the memory is minimized. Resistive Random-Access Memories (ReRAM) is a novel memory technology that allows to perform the processing (or computation) in the memory element itself thereby pushing the concept of PIM to the most optimal point. Previous work has shown that ReRAMs can efficiently be used to perform matrix vector multiplications for neural network applications, where the accuracy requirements are not very stringent.

The goal of this internship is to evaluate the potential of PIM architecture using ReRAM for signal processing applications in the physical layer of communication systems, where accuracy requirements are high.

Key responsibilities - Develop a mixed-signal model for the PIM architecture

for signal processing operation in the physical layer using existing ReRAM models from the literature.

- Validate the model and perform extensive simulations and compare with the state-of-the art processing architecture in terms of performance and power consumption.

- Identify the bottlenecks in the PIM architecture using ReRAMs and propose novel solutions.

Type: InternshipDuration: 6 weeks


Bell Labs Internship Software Defined Networking

Type: InternshipDuration: flexible, to be agreed

Bell Labs has an opportunity for a student to join our Access Control research department in Antwerp for an internship in the area of Software Defined Networking for Access Networks.In the current trend towards virtualized networks, the physical resources of an access network often need to be shared by multiple, so called, access seekers, which each represent a group of users. Examples of such access seekers are Virtual Network Operators (VNOs) serving their end-users, Virtual Private Network (VPN) providers connecting geographically distributed branches of the same company, mobile operators seeking to backhaul or fronthaul their mobile traffic, etc. Software Defined Network (SDN) technology allows to control this sharing of physical resources, by separating the control and forwarding planes. Because there are a large number of access lines to control, traffic on these lines is vigorously fluctuating and actions taken for one line often only have a local impact, a dedicated SDN controller for Access needs to be developed. As a network equipment provider, we are interested in research making the access and core network programmable in a more flexible and agile way.

Key responsibilitiesThe student will - Explore how to extend NetUnix to control access networks - Investigate efficient ways to generate typical traffic

The possibility to quickly deploy and adapt new congestion control algorithms allowed many application service providers (Google, Netflix, Microsoft, …) to try new angles which resulted in many novel congestion control schemes for TCP and QUIC (BBR, DCTCP, TCP-Prague, IoT CCs, …). Their new challenge is to provide low latency and high utilization and later to support the highly varying throughput which is to be expected in the 5G network context. As a network equipment provider, we are looking into ways to improve the interaction between new congestion control techniques and the network.

Implement a changestream abstraction over a graph query environmentType: InternshipDuration: 6 months (long term assignment)

Bell Labs has an opportunity for a student to join our Application Platforms and Software Systems research lab in Antwerp for an internship in the area of streaming graph databases.

MissionDesign, implement and test an infrastructure that implements a changestream concept for queries over graph databases / tuplestores.

BackgroundChangestreams are a popular way to query document based databases in a scalable way (e.g. rethinkdb). Typically, these changestreams are only defined over queries that involve single documents. Tuplestore query mechanisms more likely than not involve the use of join operators over multiple tuples. We have defined an extension to an existing tuplestore that would allow us to use changestreams over more or less general SPARQL-like queries (including joins) on that tuplestore.A major part of that extension deals with how the tuplestore indexing mechanisms need to be extended to support the change stream concept.

Key responsibilities - The student will familiarise himself with the use and

implementation of changestreams in existing architectures - The student will conduct a guided survey of

graph querying technologies (e.g. SPARQL) - The student will design, implement and test

extensions to the index mechanism of an existing tuplestore to enable changestream processing

- The student will design, implement and test extensions to the interface of an existing tuplestore to enable changestream processing.

- Submit a final report and give a presentation to the research team

Qualifications - Enrolled student in Master in Computer Science - Familiarity with the following items is a plus

ION R&D


Challenges for network operatorsUsers have an insatiable demand for personalized content and immersive multimedia. The cloud has sparked the imagination of a new generation of entertainment, business and commercial communities. 5G will only accelerate a whole new array of machine communications applications as meaningful Internet of Things (IoT) scenarios emerge, sharing the common goal of transforming business and enhancing the way we live, work and play. Networks of the future must be ready to handle hundreds of new and life-changing applications and services for millions of users.As humans and devices consume rapidly growing volumes of cloud-based content and services in a variety of ways, the interplay between networks and the cloud becomes more critical. The ability to adjust network resources in real time based on changes in demand or placement of content is vital to deliver the highest quality of experience (QoE) while making the best use of resources.

Security is already a primary concern, and the scale of threats will only increase as the number of endpoints multiply. Networks must meet these challenges—and this will require innovation and imagination.

MissionFor internship, we offer several possibility’s depending on your interest. It is going from pure coding to debug code errors, to full IP network provisioning, setup and debugging, to data mining on big databases that contain the results of automated tests. The coding assignments would be, here again depending on your interest, on tools, automation, IOT (internet of things) related protocols, web interfaces, databases. The error debugging would be to find why automated test cases against our routers are failing.

Key responsibilitiesAs you see in the mission, we have several topics where you can work on. During an open discussion with the candidate we will try to build an internship program that will match with the interests, the Background of the candidate and the needs at the moment of the internship.

QualificationsEnrolled student in Networking / IT, Computer Science, Electrical Engineering, preferably in Master. - A healthy mix of programming languages between Python,

TCL, HTML, CSS, PHP, JavaScript, MySQL, JQuery & Linux. - Interest in IP networks. - Interest in SW/HW. - Autonomy in working and proactivity.

With the ever expanding internet, the convergences of the Fixed and the Mobile world, the explosion of video related applications, the 5th generation of Mobile communications, the growth of the number of IOT devices … we are looking for talented students to join our teams and build the future of the connected world.

The IP network of the futureNokia strives to evolve and transform modern networks to enable the next phase of the cloud and machine era of communications. Users expect high QoE regardless of the type of content they consume or how they access it. As a result, modern networks must be highly adaptable and ideally suited to deliver superior service experiences with better security and real-time optimization.

Feel encouraged to innovateWith us, you will work with next-generation technology to design products and solutions that will shape the future.

This forces network operators to reimagine their infrastructure as they strive to keep up with its expansion. A new operating model of insight-driven automated networking is required. In this model, modern IP networks must excel in scale, efficiency, adaptability, security and longevity.The network change that often comes to mind first is sheer scale. The routers that are at the heart of networks must simply be much bigger to handle unrelenting traffic growth.

ION - Deepfield


ION-Deepfield is a Nokia owned company that builds the analytic and security solutions that monitor and defend over 90% of internet backbone networks.

We produce cutting-edge research at the intersection of data science, visualization, and network analytics, and we create, deploy, and maintain the largest global network analytics platform. Come join us and help advance state-of-the-art network intelligence. Our customers are the internet: from content providers to global network operators. There's no shortage of data in these environments; the challenge is to turn that data into actionable information for everything, from strategic business decisions to automated network operation.

The biggest players in the industry are turning to Deepfield for answers. It isn't enough that our products be intuitive, engaging, and beautiful - they also need to be reliable and scalable. That's where you come in: you'll work in a small team to help define and, most importantly, build the backend to a business intelligence application that allows the user to navigate, analyze, and explore massive data in ways that anticipate the questions they need answered.

Integrate Ubuntu MAAS and Jenkins so that MAAS can provide a scalable cloud for Jenkins

BackgroundWIn the lab we use Jenkins as an orchestrator to set up our test environments on demand. With the unavoidable tooling around it, with a simple command we are capable of starting a network consisting of 7750 routers, together with a Deepfield deployment monitoring the network. For this Jenkins has access to worker nodes in the lab and it has the ability to scale into AWS EC2 when all workers in the lab are in use.To make everything more flexible and to reduce the time that is required for bringing another Jenkins worker on-line in the lab, a successful attempt has been made to deploy Ubuntu MAAS (https://www.ubuntu.com/server/maas) into the network. This platform makes it very easy to add and deploy bare metal servers. As long as they get an IPMI IP address assigned and their BIOS is configured for PXE boot, MAAS can discover and manage them. MAAS takes care of everything (DHCP, PXE, TFTP, DNS,...) so this really is a very easy way of building a private cloud that has the potential of being very flexible.Although this already is a great improvement we are not quite there yet. Right now when a server is detected in MAAS we hit the Deploy button and our custom Ubuntu install gets deployed on it. That's a one-time action, and although this deploying is way faster and less error prone than installing each server individually, when compared to how the scaling in the Amazon cloud works, it is crystal clear that that this is still not as flexible as it could be.

Adding flexibilityThe ultimate goal is that a new server is added to MAAS as a new node, but that it does not get deployed immediately. Instead, when Jenkins notices that there are no available workers on-line, it should first query the MAAS controller and have MAAS deploy a new worker if a bare metal is still available. When the Jenkins worker is not used anymore (say after 10 minutes of idle time) Jenkins should also inform the MAAS controller that the server can be decommissioned.There are 2 main advantages. First of all, when a MAAS decommissions a node, it powers down the node so there will be a power saving. A second advantage is that we can add a bunch of servers that we also can use for other purposes if needed. With MAAS changing from one image to another is a very simple process, something that would not be possible if we would have to install the servers manually.

Building modified imagesAs it is today, building a modified image is a pain. To make this process less painful, the steps to take should be documented and should be put together in a script that can guide the end user through the process of creating a new image.

From a high level it would come down to resizing and mounting the reference image, giving the end user the possibility to chroot and make the changes, and finally pack the image and ship it to the local MAAS controller.

Success criteria - A Jenkins plugin is created similar to the

EC2 cloud plugin (https://plugins.jenkins.io/ec2) that can use MAAS as a cloud

- Jenkins can deploy a MAAS node when needed, with whatever image that is needed

- Jenkins can decommission MAAS nodes after a period of inactivity

- Building custom images for MAAS is simplified

Technologies - Jenkins - Maas - Java (Jenkins plugin) - Shell scripting (image builder)
