It looks like 2010 will be remembered as the year of 10Gbps networking. Fueled by increasing demand for internal bandwidth within the data center and cloud computing service-rich content applications including video and music streaming (which are becoming embedded in almost every type of communication) as well as real time applications. Even though 2008 and most of 2009 were tough years for many vendors, the overall spending on networking and 10Gbps networks grew.
When I am reading articles that predict the future, I like to go back in time and search for former analysis in order to establish a baseline and compare previous predictions. Sometimes it can also provide perspective on how a market is evolving, which is important to understand the different growth vector.
Network World recently cited the Dell'Oro Group
Data center deployments of 10G Ethernet are helping to drive the market, according to Dell'Oro Group. The firm expects the global Ethernet switching market to grow modestly in 2010, to $16.3 billion from $15.6 billion in 2009. This is down considerably though from the $19.3 billion market in 2008, Dell'Oro notes
Several weeks earlier they
provided some detailed numbers providing actual results for 10G vendors sales:
Total 10 Gigabit Ethernet revenues grew 10% to $737 million during the quarter, with most of the growth being driven by “purpose-built” 10 Gigabit Ethernet data center switches, Dell'Oro notes.
It is nice and very rewarding to see how in such a short amount of time those numbers beat any previous estimation (like
this Cisco white paper):
These factors are expected to continue to fuel the momentum of the 10 Gigabit Ethernet market, which is expected to rapidly grow from US $385 million in 2004 to US$2.9 billion in 2009, according to the Dell’Oro Group.
At Net Optics we see the growing demand as well and support it with a variety of solutions to support customer needs for monitoring, security, audit and convergence. One of our popular solutions is the
Link Aggregation switch

The iLink Agg Xstream is an intelligent link aggregator that combines traffic from as many as 20 network links or Span ports and sends it to four monitoring tools. Each of its 24 SFP+ ports accepts both 10G SFP+ and 1G-SFP transceivers, enabling 10G and 1G links, Span ports, and monitoring appliances to interconnect in any mix of speeds, including different fiber and copper media types. The iLink Agg Xstream automatically performs all data-rate and media-type conversions, enabling 10G traffic to be sent to 1G appliances, and 1G traffic to 10G tools. This capability protects your security appliance investment, because the iLink Agg Xstream enables you to apply your existing arsenal of 1G monitoring tools to your new 10G traffic links. You can aggregate the traffic from multiple 1G links and low-utilization 10G links to fill up the bandwidth of expensive 10G tools.

hereThe iLink Agg Xstream device supports fully configurable port mapping, so it can provide many other configurations in addition to 20 network ports to four monitor ports. Preloaded aggregation configurations include:
A single 20x4 link Aggregator
Dual 10x2 aggregators
Quad 4x2 aggregators
Preloaded regeneration configurations include:
1-to-23
Dual 1-to-11
Quad 1-to-5
In addition, any port can function as a network port or a monitor port, so you can attach more than four monitoring tools or more than 20 network links, if required. Splitting the cables into separate transmit and receive fibers makes a total of 24 network inputs and 24 monitor outputs available for concurrent use. The network inputs can be connected to external Taps or switch Span ports. Direct in-line link connections are not supported.
Its key features are listed below:
- Increases monitoring efficiency by enabling tools to view the traffic on as many as 20 network links (from external Taps or Port Aggregators) or 20 Span ports simultaneously
- Improves monitoring flexibility with fully configurable port mappings (any number of links to any number of tools)
- Provides complete visibility at 10 Gbps without interfering with the data stream and without introducing a point of failure
- Supports media type and data rate conversion with SFP+ or SFP transceiver modules on both the network and monitor ports
- Enhances monitoring security because no IP address is needed
- Provides RMON statistics such as packet counts, bandwidth utilization, and threshold alarms to increase monitoring efficiency
- No interference with the data stream and no point of failure introduced
- Remote traffic statistics and configuration
- Security options control user access
- Redundant power ensures uptime
- Compatible with all Net Optics Taps
- IEEE 802.3 compliant
- Fully RoHS compliant
While no one can really predict the future, we definitely try to create it by adding more 10G solutions that will allow us to deliver solutions and address customer needs.
