The Top Five Security Considerations for Software Defined Networks
While there is a lot of interest in the potential of Software Defined Networks, there are only a handful of actual production networks out there right now. Why? One reason is because of the security risks associated with deploying the existing technology. The following are the top five areas that need to be addressed to improve the security of this new architecture:
Secure the Controller: By separating the control and management plane from the data plane, the “brains” of the network are centralized, which theoretically enables you to make changes to improve the speed, efficiency and potentially security of your network, with just a few clicks. Because the controllers that manage the network can be used to do anything, it also means securing them is of paramount concern.
Depending to whom you talk to, “putting all your eggs in one basket” so to speak, with all the brains of the network in the Controller can be seen as bad, representing a big target and vulnerability, or good, enabling the concentration of protection efforts on one thing. (Note, it may not be that dissimilar to DNS servers today, which are hugely disruptive if taken down or compromised; however, most network administrators feel fairly comfortable in their ability to protect the DNS servers in their network.)
Protect the Controller: Protecting the availability of the controller is also critical. Commercial solutions must easily enable redundancy to reduce the impact a compromise on one controller can have on the entire network.
Establish Trust Between the Controller and the Applications and Devices: Ensuring the integrity of anything that communicates with the controller is a critical first step in making sure the network is running as it should. There must be strong, mutual authentication for the applications that run on it, as well as the switches, routers and servers it controls. Also the communications channel needs to be secure to prevent attacks, such as man-in-the-middle.
Create Robust Policy Framework: Checks and balances are needed to ensure the network is operating as it should. When changes to the controller are made, there needs to be a framework in place to ensure they are in line with corporate policies and don’t open up security risks or knock the organization out of compliance.
Forensics and Remediation: Just as in any network, understanding what is going on or what happened is vital to being able to make changes that strengthen your overall security posture and better protect you from future threats.
Most likely these risks will be addressed as the technology matures and more commercial offerings are made available to the market, but it’s important to keep in mind what needs to happen before wide-scale, production deployments can be considered.

Should Cisco Sell Its STB Business?
Rumors are spreading about Cisco wanting to unload its STB business because of shrinking margins and slow growth. If you asked me a year ago, I would have told Cisco to exit the business because of the entry of low-cost offshore competitors, the threat of OTT and likelihood that STBs would become irrelevant as consumer electronic devices (connected TVs, iPads, and game consoles) are able to stream video.
Now, I see the business a little differently. It is possible that the decline of the STB business will be slower than we think. Even as connected TVs, game consoles and tablets grow, the older sets will still need an STB device to get the content. Even with shrinking revenues and margins, the cash flow should be pretty healthy given that much of the investment has been written off. It also allows Cisco to continue to be a strategic partner and maintain a high share of spend with the MSOs and Telcos. Keeping the business would allow Cisco to retain the video engineering expertise, which is no doubt sizable and will be needed for developing new hybrid/VideoScape products.
Practically, can Cisco get anything above a fire-sale price given the slow growth forecasts for STBs? Finding a buyer will be tricky, since there are only a small number of companies that have the resources and strategic fit to want to bid on it.
Cisco has publicly stated that it does not have plans to sell its STB business, but going forward the company will have to see how fast and at what point they transition to a more profitable VideoScape strategy.

Mixed Bag for Mobile IP Infrastructure in Q4

Despite Softness, Winners Emerge in the Router and Switching Market in Q4
Cisco gained in Core, Access Aggregation, and Carrier Ethernet, which it attributed to a solid book of orders across all regions. The company has been reorganizing and announced that it had reached its goal of reducing $1B in annual expenses. Cisco is gaining share against Juniper, which decreased routing revenue 8.1% sequentially and 22.4% y/y. However, Juniper posted a 36% y/y increase in switching revenue and a 33% y/y quarterly increase, which is in part due to solid sales of infrastructure products such as QFabric and Juniper's wireless LAN products. Alcatel-Lucent, which is benefiting from the market momentum for 100G IP/optical as well as providers replacing and leveraging 100GE and IPv6 transition technologies has 16.5% of the total market share. ALU posted gains in Total Carrier Routing, ESER, MSER, and Carrier Ethernet.
We still see mixed signals on the economic outlook and overall CapEx spending for 2012, but despite the macro climate, mobility and business video services are strong areas for spending and growth in 2012. The US economy has had slow growth over the past two years, yet earnings by companies in Standard & Poor’s 500 companies increased by more then 15% each quarter, which is a good sign for the economic recovery/growth. Traditionally in a presidential election year, perceptions and fundamentals may widen since debates tend to highlight the problems and not the positive fundamentals.
Vendor | Rank | Market Share ($) |
Cisco | 1 | 53.7% |
Alcatel-Lucent | 2 | 19.0% |
Juniper | 3 | 16.5% |
Tellabs | 4 | 2.6% |
Huawei | 5 | 2.5% |
QUARTERLY TREND and DRIVER HIGHLIGHTS
- New technologies are driving innovation, which is being driven by market pressures and demands for enterprises to move critical and nonbusiness critical processes to cloud or virtualized infrastructures. With many countries reaching 100% mobile device penetration and with more people owning multiple mobile devices, fixed and mobile operators have to evolve their broadband access networks to create scalable capacity to deliver multiservice support, operational efficiency and an exceptional user experience. Vendors will need to react and offer innovative solutions that address these requirements.
- Mobility and cloud computing are two segments driving all aspects of the telecom industry. Both markets continue to be driven by vendors introducing new technologies for data centers, security, mobile Internet, and storage.
- Data plane traffic growth is being driven by the rapid adoption of video services and cloud services; control plane traffic growth is being driven by migration from fixed and fairly static information sources to personalized, socially-inclusive, and mobile information sources.

Worldwide Optical Market Jumps in Q4
Vendor | Rank | 2011 Market Share (%) |
Huawei | 1 | 22.5% |
Alcatel-Lucent | 2 | 16.1% |
ZTE | 3 | 12.8% |
Ciena | 4 | 9.6% |
Fujitsu | 5 | 6.6% |
QUARTERLY TREND and DRIVER HIGHLIGHTS
- Core node sites will ultimately require up to 100T of capacity.
- Metro DC to DC and DC to Internet POP deployments will be the fastest growing segment in the next few years.
- Capital expenditure is relatively flat in the traditional market but up in the content provider space.
- Spending on infrastructure by Google, Facebook, Amazon and Microsoft was up by significant percentages.
- Q4 was assisted by solid increases spending by MSOs as well as spending by the U.S. government.
Demand from content providers and cautious spending by top tier providers are rapidly and dynamically changing the optical market. Vendors that are paying attention to what content providers want, understand how they are deploying product, and what they are discussing for next-generation access networks and metro networks will be in much better position to weather this slow economic recovery. The good news is that the overall market up almost 10% over 2010, which is a good sign for the industry.
