News on October 12, 2013, as optical fiber networks gradually reach their theoretical capacity limits, this has threatened the development of
the Internet.
New fibers such as multicore fibers can overcome critical capacity barriers and are therefore the focus of
research worldwide.
The University of Bristol in the United Kingdom, in collaboration with the Japan Institute for Information and Communications Technology (NICT), has successfully demonstrated for the first time that multicore fiber networks will be an important cornerstone
of the future Internet infrastructure.
The research uses space division multiplexing (SDM) and software-defined network (SDN) control provided by multi-core fiber, which is expected to meet the growing data consumption demand
of communication networks.
The collaboration between the University of Bristol's High Performance Networks Group and NICT Japan successfully demonstrated for the first time that a full-featured multi-core optical network leverages the flexibility and intelligence provided by SDN to serve
emerging Internet applications such as cloud computing around the world.
The Bristol research team developed SDN control based on an extension of the OpenFlow protocol and provided a new type of network node device
.
NICT used multi-core optical fibers (MCFs) technology and a new transmission technology
based on self-zero difference detection (SHD) technology in the demonstration.
OpenFlow interface applications dynamically configure network nodes in such a way that the network can efficiently handle application-specific traffic requirements such as bandwidth, transmission quality, etc
.
Professor Dimitra Simeonidou, Head of the High Performance Networks Group at the University of Bristol, said: "While most of the ongoing research has only focused on improving data throughput and transmission distance over point-to-point links, it is clear that the success of new fibre technologies will be governed by the suitability of fibre networks and the required network capabilities
.
”
"As far as network protocols are concerned, SDN has been gaining more and more attention
recently.
It is a technology
that enables network operators to easily improve their network infrastructure to adapt to changes in users and application requirements to improve network efficiency.
However, so far, SDN has only been applied to single-core fiber networks, which is therefore limited by the current fiber infrastructure capacity bottleneck
.
”
Bristol and NICT hope to further improve the software and hardware
of network technology in the future.
At the same time, work with network operators to promote the practical use of
multicore fiber networks.
The research was presented
as an important academic paper at ECOC in London last month (September 26).
