SDN&NFV for Telecom operators and Enterprise networks

Modern telecom networks contain large amounts of proprietary equipment, which is normally highly specialized and implemented for specific functionality. Every new service requires the installation of a new set of equipment that supports the required functionality and its configuration. In addition to high capital and operating costs, this approach does not allow scaling the service dynamically, configure it automatically and maintain its efficiency and use of resources.

Current trends, such as the growing number of Internet-connected devices, the exponential growth of information, the development of cloud computing, BYOD, and big data, change the telecommunications industry extremely fast. Almost the same changes will occur in corporate networks, but more slowly. There is also the increasing volume of network traffic; therefore, business needs to configure large-scale networks.

We believe that these changes in operators business will take several years. On one hand, no network transformations are cheap. For example, American telecom giant AT&T plans that virtualization of 75% of its network will take at least 6 years from 2014 to 2020. Company’s own investment into this project will amount to about $ 45 billion. On the other hand, the business model of an operator also has to change. The importance of implementing SDN and NFV technologies for the industry can be compared to the process of transition from analogue to digital stations, which also took quite a long time.

ARCCN works on solutions in the following areas:

  • Telco and Enterprise networks management
Controller (or Network OS with applications) is a key element of the SDN network, which serves as a control element of the network infrastructure and data flows in the network. Characteristics of performance, scalability and reliability of the network depend on the characteristics of Network Operating System (Network OS). In fact, the controller is a dedicated server that runs special software, consisting of Network OS and network management applications.

RunOS is the first Russian SDN controller. It is the most efficient and fastest experimentally approved controller. RunOS provides flexible and convenient system for new network applications development.

Key features:
  • Conflict resolution system in the network applications rules;
  • Highest performance;
  • Administrator’s GUI;
  • Wide range of network services and applications for data transport networks.
One of the main advantages in RunOS is an ability of easy applications development for the Controller. There are currently the following applications available: B2C, VPN (P2P, MP), B2B; Multicast; Storm Control; LAG / LACP; In_Band / Out_of_Band management; VLAN translation; multiparametric routing; topology discovery; traffic mirroring; QoS control; link aggregation (with LACP support); and opportunities for traffic engineering.

  • High performance hardware switches based on network processors.
We believe that the best way to develop an OpenFlow SDN switch is to use a network processor.

On one hand, it provides a possibility to change the behavior of the device by its reprogramming, on the other hand – helps to provide high port density, higher performance during traffic processing. It also needs less place in a rack compared to the server and allows to work with different types of tables and memory, including associative, more quickly. Network processors allow achieving the desired functionality by changing the software in accordance to new versions of the OpenFlow protocol. Such companies as Huawei, Intel, and EZchip (acquired by Mellanox in 2016) currently produce network processors. The Israel Company EZchip (Mellanox) specializes in the production of these products for many years and offers several platforms based on network processors NP-4, NP-5 and processor NPS-400, released in 2016. The evaluation system based on NP-5 can provide a capacity of up to 240 Gb/s, to handle 500 million packets per second, has a 5-level hierarchical queuing system, supports WFQ with priority queuing, WRED, Shaping (CIR, PIR), per flow metering , marking, policing for millions of streams.  It also provides the collection of statistics using up to 512M meters.

The issue of availability and scalability for each instance of the network function is a key point for telecom operators and corporate data center operators. In this area, the main purpose is to develop a cloud-based platform that is able to manage the resources allocated to the data center with a help of the pre-installed software (i.e. OpenStack).
