OKLAHOMA metropolis - At a time when the state has a funds surplus and the economic system is strong, the State office of administration and business services, is asking the legislature for an emergency $16 million or they may need to furlough personnel.
The company provides fiscal, property, procuring, human resources and IT services to all state companies, and helps the governor boost a state budget.

OMES says in the past six months it has not crammed around 50 positions to save money.
“Our costs are carrying on with to increase 12 months after 12 months with a few of our largest providers. those expenses will proceed to boost because it fees will proceed to at all times enhance,” talked about Reese.
Senator Roger Thompson (R) of Okemah asked, “Is $sixteen million that drop-lifeless number or is it $4 million, $3 million, $7 million. what's it?”
“there's $7 million that we owe to providers at the moment that's over 60 days. So, from my standpoint that would be our drop-dead figure for April,” answered Brandy Manek with OMES.
OMES says without the money the company would possible should furlough employees for six days.
Lawmakers say they desire some assurance that this won’t ensue once again.
“I just agree with that we should have a plan aside from just announcing we received $sixteen million we want, supply it to us after which what occurs after that?” consultant Charles Ortega (R) of Altus asked.
OMES says it is looking at the right way to make the company greater effective.
Lawmakers may still come to a decision in the following couple of weeks even if to supply the company the funds.

Wireless LANs were once seen as the easy alternative to the wired LAN. After all, they weren't used for primary network access and they didn't have to be eternally stable or particularly far-reaching. That's no longer the case— and that leaves users with plenty of wireless LAN questions.
SearchNetworking.com readers have sent in a host of wireless LAN questions related to 802.11n migration, wireless LAN performance management and design of wireless mesh networks, among other topics.
SearchNetworking.com wireless expert Lisa Phifer has been answering readers’ questions for years. Here is a selection of Phifer's most commonly read questions related to wireless network migration and management.
When old technology meets new, wireless LAN questions arise
It's very rare that an IT shop is able to do a complete rip-and-replace on a wireless network. Instead, it often finds itself combining newer 802.11n technology with older 802.11 equipment. Integrating this equipment raises questions of how to use varying APs together and whether neighboring equipment can get along.
Question: What is the impact of having both the 802.11g and 802.11n access points in the same environment? Will this cause conflicts for the clients in this environment? Can you catalog users by the frequency?
Answer: 802.11g access points (APs) operate in the 2.4 GHz ISM band, using 20 MHz wide channels. 802.11n APs can operate in either the ISM or UNII band— that's the set of channels above 5 GHz— with the option of using 40 MHz wide channels.
Read the rest of this answer to the question of combining 802.11g and 802.11n APs.
Question: When a company completes migration to 802.11n, what can it do to avoid coexistence problems with neighboring businesses that still use 802.11g?
Answer: The 802.11n high throughput (HT) standard defines three modes of operation: a legacy (non-HT) mode, a greenfield (HT-only) mode and a mixed mode where HT protection mechanisms ensure that transmissions can be detected by both old 802.11a/g/b devices and new 802.11n devices.
Read the rest of Lisa's answer on how to avoid coexistence problems when migrating to 802.11n.
Improving wireless LAN performance
Implementing wireless LANs is one thing, keeping them running smoothly is another. That process takes ongoing wireless LAN monitoring and troubleshooting, as well as architecture strategies that optimize networks in the long run.
Question: What is your take on 7/24 Wireless Quality Assurance as a cost-effective alternative to ad hoc troubleshooting?
Answer: Automated performance monitoring and proactive management to maintain quality-of-service targets and service-level agreements (SLAs) is a necessary ingredient of any mission-critical wireless LAN (WLAN).
Read more of Lisa's advice on automated performance monitoring in the wireless LAN.
Question: What are the best methods for handling rogue APs? Can you suggest a small-scale business network solution for dealing with rogue access points?
Answer: Any unknown access point (AP) operating in or close to your facility is a potential rogue— but few turn out to be real threats. The trick is to reliably tell the difference— and fast.
Read Lisa's advice on monitoring for rogue APs.
Mesh wireless LANs
Using a mesh topology— in which wireless nodes talk to each other to form a network— is not the most common wireless LAN architecture, but it is increasingly being used to extend the reach of Wi-Fi networks over greater outdoor geographic areas. It is also often used to create ad hoc wireless LANs within the enterprise.
Question: We have installed a wireless mesh network that connects two access points (APs) to mesh nodes that are mounted at 25 meters high on 23 light poles. Poles are distributed around a container yard that measures 650 meters by 1,000 meters. There are six rows of containers, varying in height depending upon container movement, stacked to a maximum of 6 containers high. Walkways and vehicle lanes are located in between container stacks. We had expected to achieve 10 Mbps throughput on the ground but do not. Please recommend a solution.
Read Lisa's recommendation for increasing throughput on this wireless mesh network.
Question: We have a small business office that is too large to cover with a single 802.11n AP, and we would also like to extend the 802.11n WLAN to a second small building 125 feet away from our main building. How can we extend an 802.11n WLAN to meet these needs?
Answer: To build a network that delivers solid coverage to both offices, you must solve two problems: First, you must extend 802.11n WLAN coverage provided by your indoor WLAN, and then you must join two indoor WLANs together with a short outdoor wireless link.
Lisa says one way to extend this network is through wireless mesh. Read more.
Question: I'm setting up a WLAN in a hotel using a Colubris MSC 3200 access point (AP)/controller. For some reason the Internet keeps dropping from the controller. The signal needs to span about 1,000 feet, there is no RADIUS (Remote Authentication Dial In User Service) server, and I do not have any detailed info on the 3200's settings. In the hotel there are 16 APs on the same floor, each addressed by static IP's, with one transmit radio and one receive radio. Is the transmit radio (which uses a different SSID that I cannot connect to) supposed to be a bridge?
Answer: It sounds like your hotel's WLAN might be designed to use a wireless backhaul mesh to connect all APs to the Internet via the Colubris MSC 3200 AP/controller. …
Read the rest of Lisa's advice on what to do about APs dropping from a wireless mesh network.
EUC with HCI: Why It Matters
802.11ac Wi-Fi is slowly making headway in the enterprise, but the specification's speed and performance improvements over 802.11n, as well as organizations' adoption of BYOD, create traffic capture and analysis challenges. Namely, 802.11ac and BYOD both encourage a dramatic increase in traffic over enterprise wireless networks. Network and application performance analysis tools vendor WildPackets is stepping up to the plate with today's release of Omni Distributed Analysis Platform 7.9.5.Factors driving 802.11ac adoption
Though still in Wave 1, the 802.11ac standard already promises data speeds of up to 7 Gbps in the 5GHz spectrum, as well as lower latency and improvements to coverage and performance overall. These features make 802.11ac particularly well-suited for modern enterprise applications like VoIP and video conferencing. The enterprise is growing more and more comfortable with real-time collaboration overall, which 802.11ac helps enable.
802.11ac also offers performance benefits for BYOD organizations. With BYOD often comes a significant increase in the load on the network thanks to a proliferation of devices onsite. It's not uncommon, for example, for workers to stream music or videos or join video conferences on their tablets while simultaneously working from laptops also connected to the WLAN. Employees switching their smartphones over to the wireless network to save on their mobile data plans further increase the load. 802.11ac's greater capacity and parallel transmission capabilities can preserve application performance in the face of growing demand. Luckily for BYOD enterprises, the newer generations of consumer devices often come 802.11ac-ready.
Finally, though 802.11n still dominates device sales, 802.11ac is gaining popularity, according to ABI Research. Of particular importance is 802.11ac's backwards compatibility with earlier Wi-Fi specifications. Enterprises looking to begin the transition aren't facing a forklift upgrade, a factor which will likely play into purchasing decisions for some time to come.
But while 802.11ac offers a multitude of benefits to the enterprise, it does create some challenges when it comes to wireless network management and troubleshooting.802.11ac network management challenges, and how WildPackets addresses them
The 802.11a/b/g/n standards have been around for long enough to develop a solid ecosystem of network management and traffic analysis tools. Not so with 802.11ac. Wi-Fi traffic is typically captured locally, using either laptops equipped with special software and USB adapters, or dedicated devices like the Fluke Networks OptiView XG Network Analysis Tablet that Enterprise Networking Planet reviewed earlier this year. But without 802.11ac support—which even the OptiView XG currently lacks—these tools may prove inadequate for the WLANs of the near future, according to WildPackets.
"The antennas really don't keep up with 802.11ac data rates anymore, and the USB adapters don't keep up anymore," Jay Botelho, WildPackets director of product management, told me. Additionally, the need for a network engineer or administrator at the point of the network problem can be an issue.
"In a lot of cases, the networks are so dispersed now and have such small network engineering staffs that they're usually not near the problem," Botelho said.
Version 7.9.5 of the WildPackets Omni Distributed Analysis Platform aims to address these problems. The platform provides remote 802.11ac data capture and analysis by using commercial enterprise access points (APs) themselves as data capture devices rather than relying on external means. The platform already works with Cisco and Aruba 802.11ac APs, among others.
Using APs as sensors isn't a new concept for WildPackets, but "we've had to make a lot more changes, and we have worked very closely with Cisco and Aruba so far to make this work," Botelho said. The approach provides full 802.11ac traffic capture and enables engineers and admins to troubleshoot their WLANs without having to be onsite, a boon for distributed enterprises with remote and branch offices to support.Getting ahead of the enterprise 802.11ac network management market
The 802.11ac standard is still relatively new, with only a small footprint in the enterprise, creating an opportunity for WildPackets. The company is claiming first-to-market bragging rights for today's release of Omni Distributed Analysis Platform 7.9.5, which is "the industry's first Wi-Fi analysis solution for gigabit wireless local area networks" and "the only commercial solution available for managing and troubleshooting new enterprise 802.11ac networks," according to a WildPackets statement.
"The manufacturers that are out there selling to the enterprises—Cisco, Aruba, Meru—they've really just come to market with their first ac products. And what we're finding as a company is that people are having real difficulty being able to monitor those new networks because they're so much faster than they were before. We've been trying to get ahead of the market, and we think we will be," Botelho said.

Hardware companies are vying to be winners of the future data economy, powered by 5G, cloud computing, and the Internet of Things (IoT). If you as an investor can separate the wheat from the chaff, you could come out a big winner. Two such hardware companies are Arista Networks (NYSE:ANET) and Sierra Wireless (NASDAQ:SWIR).
Arista Networks makes cloud data center switches. Its disruptive platform uses merchant silicon (off the shelf chips produced by third parties) tied together via Arista's EOS operating system. EOS plus merchant silicon allows data center operators to run Arista's switches in a flexible, low-cost fashion, making Arista a preferred vendor to fill cloud data centers. Recently, Arista has expanded into campus networking and into routers as well.
Sierra Wireless makes IoT-related modules, gateways, modems, sensors, and software for connected devices. Sierra's products go into connected automobiles, mobile devices, networking devices, and "smart" industrial equipment.Recent trends
If you are going to pick the company with the better earnings momentum, the clear winner is Arista.
Arista trounced Sierra Wireless' growth in 2018, as revenue rose nearly 31% vs. Sierra's mere 14.9% growth rate. In addition, Arista was solidly profitable, with a net profit margin of 15.3%, whereas Sierra lost money in 2018, with negative (3.1%) net margins.
However, both companies booked several nonrecurring charges. Arista Networks settled a patent dispute with Cisco (NASDAQ:CSCO), in which it had to pay the switching giant $405 million in 2018. Without that charge and other GAAP charges, Arista's non-GAAP net income margin was nearly 30%, up a whopping 45.3% over 2017.
Sierra Wireless, on the other hand, incurred several special charges in 2018, but not for the same reasons. It's fallen on hard times, suffering weakness across its main auto business and a loss of market share among mobile and networking solutions. So, new CEO Kent Thexton is restructuring the business, which means layoffs, writedowns, and asset disposals.
In 2018, the company took over $22 million in charges related to acquisitions, restructuring costs, a loss on the sale of its iTank business, and various other "nonrecurring" charges. Without these various charges, the company's non-GAAP net margin was a more respectable 16.1%.
That's certainly better than losses, but doesn't come close to Arista's momentum and profitability.What 2019 has in store for each
Looking ahead to this year, things appear to be steady as she goes for Arista, but they're taking a turn for the worse for Sierra. Sierra's guidance calls only for flat revenue in 2019, with a rather steep decline in non-GAAP earnings per share (EPS), from the $0.90 posted last year to just $0.30 per share in 2019. The company has run into problems with some core segments and is investing in new solutions for 5G connectivity and LPWA (low-power wide area network) modules. Those applications have large opportunities ahead of them, but the payoff is still a ways away, and it's an open question as to whether Sierra will win over competitors.
While Arista doesn't give full-year guidance, the company did forecast roughly 25.5% revenue growth next quarter, as well as continued great margins. Arista continues to benefit from its low-cost advantage and flexibility versus larger rivals such as Cisco, and its products are indispensable to the multiyear buildout of global cloud infrastructures, as well as the need for faster and improved networking capabilities.
In other words, Arista appears to enjoy quite the formidable competitive advantage and a less cyclical business, while Sierra Wireless, though offering leading products, appears to be under more competitive pressures and is more sensitive to business cycles in areas like automobiles and PCs.
As you can imagine, this puts Arista in a much more favorable spot.Valuation
Of course, valuation also plays into one's decision. On that front, Arista is much more expensive -- the company trades at 28.8 times its 2020 non-GAAP earnings estimates, while Sierra Wireless trades at only around 15.7 times 2020 estimates -- obviously, much cheaper.
However, analysts' 2020 EPS estimate of $0.77 for Sierra (see the chart below) assumes a rebound from the company's own 2019 EPS estimate of just $0.30. So, while Sierra is no doubt the cheaper stock, one still needs to be confident it can turn the ship around, and it might take a year or more to find out whether Thexton's prescription is working.Growth or value?
For those willing to bet on turnaround situations, Sierra Wireless could be the superior pick. If Thexton's plans work out, Sierra's beaten-down stock could surge much higher. However, in the current market environment, high-quality growth stocks with more predictable results seem to be winning the day. With its top-notch management, low-cost advantage, and consistent growth, I still believe Arista is the better play in 2019.
