“Paving the Way for 5G”
Mail to Expert
ARGELA has been working on OpenFlow since the release of OpenFlow 1.0 in 2009 and was a member of ONF from 2009 to 2011. ARGELA has implemented all older OpenFlow versions and currently working on OpenFlow 1.5.1. The implemented OpenFlow stack has been tested with switches from various vendors, including Pronto, HP, NEC, Brocade, Centec, and Arista, as well as under the well-known MiniNet environment.
In addition to working with most open source SDN controllers, ARGELA has developed its own controller, namely yakamOS as well as various network applications on yakamOS. ARGELA SDN suite is a Network Access Control framework, which is built on top of yakamOS controller using OpenFlow 1.3.
Argela has experience with the following SDN controllers, for which it provides integration services and application development:
ARGELA has experience in developing applications on top of SDN controllers. ARGELA’s yakamOS controller provides a northbound API for easy application development. The following applications, which are included in ARGELA SDN Suite, have been developed by ARGELA:
ARGELA participates in ETSI-NFV efforts and has contributed to the NFV Whitepaper 3 (Network Operator Perspectives on Industry Progress). We know the trends and specifications of ETSI-NFV and provides system integration services.
ARGELA has integrated SDN controller with OpenStack, and has experience with Docker and other containers, OpNFV and Arno.
ARGELA has experience in network function placement and virtual function migration/replacement as well as NFV management and orchestration systems.
ARGELA has developed the following virtual functions:
SDN domains consist of different content-providers and ISP networks, each managed by their own controller according to different policies. Every domain is considered as an autonomous system (AS).
Properties of the multi-domain SDN controller architecture proposed by ARGELA is as follows:
Since traffic diversity and volume increase with growing popularity of mobile applications, there is the strong need to manage the traffic carried by networks through bandwidth allocation, while enforcing policies and providing fault tolerance. In traditional networks, configuration changes require many resources (including time) and are error-prone, troubleshooting and recovering from failures take long, and management tools do not provide enough agility to “program” the network. Here SDN can simplify network management while enabling new services, by employing dynamic traffic management. ARGELA traffic engineering suite provides:
