The advent of smartphones and the associated change in usage patterns indicates that carrier voice revenues are constantly going down and are expected to almost vanish in the near future. Data revenues are picking up but not at a rate which will make up for the shortfall in voice revenues. Also, the increase in data revenue is accompanied by a corresponding increase in traffic. This leads to higher costs in deploying and operating networks as well as a significant growth in network complexity. In this project we will be working on
Telecom operators are demanding more flexible, scalable and energy efficient products. As a system integrator managing networks for operators, Ericsson realize that the benefits of using modern and improved systems is becoming even more critical, as they offer a reduced Operational and Capital Expenditure (i.e. OPEX and CAPEX) of Information and Communication Technology (ICT) systems. The goal of this project is to develop a mechanism to prevent congestion in the network, prevent packets from being dropped and to guarantee delivery of packets between collaborating end-hosts.
The IP Multimedia Subsystem (IMS) is a key component in the Mobile Next Generation Network, which is used by telecommunications operators throughout the world to provide access to multimedia and broadband services. As these services become more sophisticated, and as the number of clients rises drastically, it is increasingly expensive to install and operate a network that will satisfy the users' expectations. Cloud computing (combined with high-speed networks) provides a potential method for reducing the installation and operational costs of IMS.
The concept of Software-Defined Networking (SDN) has recently gained significant attention as a practical and flexible way to create programmable networks, where new network services can be deployed or dynamically adjusted with ease. One application of this concept could be in enhancing the reliability and survivability of backbone communication networks.
This project is primarily focused on virtualizing wireless access network so that multiple operators can share the same physical resources while being able to stay isolated from each other. The basic idea is to allow wireless access points from different operators form a single virtual access point that efficiently manages its available resources. The goal is to exploit the advantages that can be obtained from virtualizing the air interface (i.e., spectrum sharing), protocol virtualization and flow-based virtualization.

This project will allow the research group at Ericsson Canada Inc. to produce in less time more R&D results and proof of concept related to short-reach optical interconnects applied to ICT systems. This will keep the interest of the mother company in Sweden and help us attract other interesting R&D mandates in Ericsson Montreal to eventually create new local employment positions.
In recent years, the rise of ultrabooks and mobile devices has been accompanied by an ever-increasing need for reliable high-bandwidth wireless communications. Their widespread use, combined with the industry’s move to virtualized cloud services, has put additional pressure on the Internet’s back-end infrastructure. Moreover, this increased load has coincided with a progressive shift in use-cases, as customers expect dependable and secure low-latency Voice-over-Internet-Protocol (VoIP) communications, fast software downloads and an almost instantaneous streaming of content.
Software designed Networks (SDN), in particular OpenFlow and FORCES, encourage the writing of network protocols and policies as programs with the stated goal to make those programs ever more expressive, more predictable, more evolvable and more usable. Within the OpenFlow initiative, the level of programmability is expressed in a set of policy rules that are distributed over a set of matchfield tables. The rules are expressed as matchfields and actions whereby the matchfields require searching over a 14-tuple structure. This is the main bottleneck issue for flow packet processing.
This Mitacs-Accelerate program will support a internships for graduate students in the areas of services and applications using next generation communications, Internet, and cloud computing. The interns will be placed in Canadian telecom and networking providers and vendors and will undertake research projects defined jointly with these partners. The program will prepare graduates to work in industry and will foster collaboration between universities and industry.
