Ethernet-VPN vs IP-VPN

What's the pro's and con's of an Ethernet VPN compared with an IP-based VPN?

The answer to this actually depends if you have a switch based network, or a router based network. An Ethernet VPN is equivalent to two switches communicating securely, thus creating a private LAN. An IP-based VPN is equivalent to two routers communicating securely, thus creating secure connection between two different subnets.

An Ethernet VPN is going to be copying more data (the ethernet headers). On the other hand, you can do some neat things with MAC layer filtering. (This doesn't really add to security because it's easy to fake, but whatever.) And you can run obsolete protocols like DecNet or IPX/SPX. And you will get Ethernet broadcasts over the wire. (This is a bad thing, since computers are quite chatty.)

IP VPNs are used far more widely. Presumably, this makes them more secure (i.e. battle tested). I'd say go with IP VPN unless you have a really compelling reason to copy that lower layer around.

However, I'm not sure we are comparing apples to apples here. An ethernet "VPN" is just an isolated broadcast domain carried across multiple carriers. This could be VPLS or Tunneled VLAN's. If you want to encrypt you are going to use SSL or IPSec or similar, which makes it an IP-based VPN over Ethernet.

An IP-based VPN is just that, an encrypted channel across a shared IP segment. Unless, of course, you are using VPN to refer to an MPLS network sans encryption.

In either case, I would look at the cost and the SLA associated with each. Since they are both doing the same thing, essentially, pick the provider with the better terms and conditions.

Also, if you're doing voice services you might want to consider IP instead of Ethernet so you have more control over jitter, provided your IP provider allows you to set QOS across the network.

If all of that just confuses you more …. here’s a solution. Request the free assistance available through this link …. simply describe in the comments section the specifics of what you need the solution to accomplish for your network. Include the address location for where this network will be installed as well as the npx for that location. The comparison software and expert advisors will do the rest for you.

Apple Or Android: Who Has Better Business Applications?

Apple has roughly 93,000 apps and Google/Android has roughly 23,000. But ... which one has apps that are more useful for the business person?

I don't know how this translates into the availability of better apps ….. but I don't like how "locked down" Apple keeps their products. My brother uses Android on a business phone and has been extremely pleased with it. With Android you can use Google's app marketplace ….. but you also have the option to venture outside of their walled garden. Not something Apple lets you do. This means fewer hurdles if a business wants to develop their own apps.

I can't speak for iPhone apps ….. but I have seen a lot of open source programs that have been ported over to Android. This made my brothers transition over to Android very easy. I also take the number of available apps each platform has with a grain of salt. A lot of those are games or are otherwise not helpful for business use.

Who has the best business apps really depends on what tasks you need to perform. I'd start with making a list of your "must have" apps that are deal breakers if a platform doesn't offer them. If iPhone has it and Android doesn't ….. then you have your personal answer. If they both have it then check out the online reviews.

For a strictly business use, BlackBerry is still a better choice over both iPhone an Android. Key reasons ….. security & central device management.

In terms of apps, being the major business mobile platform in the US for several years already, BlackBerry is supported by all major business apps. And when it comes to mobile business apps, the number of apps in app stores is less important than the long-term support of major ERP/CRM/UC/etc vendors.

Both iPhone and Android currently lag business features like …..

1) Exchange integration
2) VPN
3) Desktop syncing.
4) Enterprise Applications
5) Conferencing
6) Device Networking

My recommendation would be to get a Blackberry as it supports all these above features. Hence, for your requirement if these features are important then you would have to think about the Blackberry phones first.

To get yourself a Blackberry .... usually free with a service sign-up ... and including unadvertised special deals .... look over what is listed here:

Smart Phone Deals

Use the tools they have there to search and compare what kinds of deals you can get from the various providers. You should be pleasantly surprised.

Hospitals Replacing Pagers With A Smart Phone …. Good Or Bad Idea?

Use of smart phones in the healthcare environment …. in place of the traditional pager … is simply smart. The pun is intended too. The old pager approach is just too limiting given today’s robust communication options. Medical professionals need more than a “beep” and a number to call. Smart phones offer so much more capability and flexibility which in the long run enhances communication and ultimately patient care quality.

SigmaPage offers a solution that facilitates electronic healthcare communications, which includes On-Call Scheduling as well as On-Call Paging for hospitals as well as private practices. Here are some of the key learnings for potential users:

Pros …..

1. The SigmaPage device ….. Most physicians carry smart phones (iPhones, Blackberry, etc.) anyway. They are happy to consolidate all their communications into one device. Besides, smart phones do so much more than pagers can. They support applications that facilitate easy sharing of information and schedules. Text messages and emails facilitate fast communications.

2. Privacy ….. One concern physicians have is privacy. They do not like to share their smart phone numbers since they fear it will get abused and they will receive calls at the wrong time (at night), esp. when they are not on call. The SigmaPage product takes care of this privacy concern. At no point in time do they display physician contact info (phone number, email address, etc.) to the end user. Lack of privacy can be a negative of smart phones, which happens to be a pro because of the uniqueness of this product.

3. Technology ….. SigmaPage also has a technology called Clik2Talk, where nurses and hospital based personnel can talk to physicians directly with the click of a button without knowing their phone numbers. These calls can be received on smart phones or any landline at times physicians choose to be called instead of paged. Obviously, pagers do not facilitate such technology.

Cons …..

1. Adoption ….. As with any new technology or habit, you’ll find that some physicians are so used to their pagers, they do not want to give them up. To facilitate this, SigmaPage product works with existing pagers and paging system seamlessly.

2. Separation ….. Physicians like to keep their personal life separate from their professional lives. When a pager goes off, it’s all about work, so it facilitates that separation.

3. Urgency ….. Pagers signal urgency of response. This can be replicated on smart phones by special/distinct ringtones that also signify the same urgency.

Financial Impact …..

Hospitals can save a ton of money by converting to smart phones. These savings come from getting rid of pagers as well as from more streamlined workflow and integration of communications.

Resistance …..

I believe the benefits of EMR/EHR systems has opened eyes to benefits of leveraging technology in the healthcare environment, so resistance has decreased over the years.

Advice …..

Since we are not a hospital, any advice may not be pertinent. However, paging is a small part of the overall communications in the hospital or private practice. Current paging systems do not integrate scheduling seamlessly and do not facilitate other forms of communication. If you look at communication as a whole, there are many benefits to be availed of when using smart phones based technology. Those benefits cannot be delivered by smart phones alone. They have to be part of an integrated communications solution.

Benefits Of Business Ethernet

Business Ethernet has fast become the solution of choice for many company voice and data network installations. The benefits gained by the owning business are substantial and have created an ardent following of satisfied users.

If you and your company are in the process of designing a new network, expanding an existing network, wish to upgrade current capabilities and performance …. Business Ethernet is definitely an option that should be at the top of your list.

Traditional implementations of Ethernet support data transfers at the rate of 10 Mbps (Megabits Per Second). Over time, the increasing demand for higher performance and faster data transfer techniques has catalyzed the introduction of better technologies such as Fast Ethernet and Gigabit Ethernet. Where Fast Ethernet helps you implement networks with data transfer speed up to 100 Mbps Gigabit Ethernet, as the names suggests, are even faster allowing speeds up to 1000 Mbps or 1 Gbps.

Key Benefits of Ethernet to a Business …..

Popularity of Ethernet in today’s business environment is triggered by several benefits, out of which simplicity, granularity, and flexibility that it offers top the list. These benefits enable enterprises to implement solutions that enable them to integrate several useful features, such as Private Networks (VPN), Voice-over-Internet Protocol (VoIP), audio and video teleconferencing, Virtual remote storage, multimedia content sharing, and many more other useful features that helps them take their business to new heights.

Some of the many benefits that Ethernet offers an enterprise are:

* Simplicity ……

Ethernet can be easily extended to WAN which makes it quite simple for IT managers to incorporate high-end features in the organization’s LAN. In other words, a well-implemented Ethernet serves as a building-block to add new services to the network and to interconnect new facilities.

* High Bandwidth ……

According to a recent study the bandwidth requirements of medium to large size companies increases by 25-50% per annum. The various bandwidth options offered by Ethernet in the ranges of 10 (Traditional Ethernet), 100 (Fast Ethernet), and 1000 (Gigabit Ethernet) Mbps makes it easy for enterprises to scale their Ethernet implementations as the bandwidth needs grow.

* Scalability …..

With the continuously increasing need for better bandwidth, enterprises today are asking for scalable bandwidth solutions that they can control dynamically and increment bandwidth in small segments. For instance, they may want to increase the bandwidth in increments of 10 Mbps—10, 20, 30, 40, and 50 Mbps or in the increments of 100 Mbps—100, 200, 300, 400 Mbps, and so on.

* Easy Provisioning ….

Ethernet is quite easy to provision as it minimizes the need for hardware replacement each time the bandwidth is increased. For instance, a bandwidth change from 10 Mbps to 20 Mbps can be easily provisioned just by making a few changes in the software of the network equipment used. Moreover, just making a few modifications you can upgrade to Gigabit Ethernet over the same Ethernet cable infrastructure that you would have laid for traditional and Fast Ethernets.

* Flexibility ….

Ethernet uses a common interface which is independent of the bandwidth. This makes internetworking between different devices on your network quite simple. Flexibility of Ethernet technology assures rapid provisioning characteristics, offers easy migration from lower to higher speeds, and enables you to easily integrate new technologies. This is the reason why Ethernet is an ideal choice for enterprises with growing bandwidth and technology requirements.

Today, Ethernet has evolved from the LAN technology to a cost-effective, scalable, and flexible solution for enterprises of all sizes. This overall development has gained momentum due to wide acceptance of the technology by enterprises, service providers, and vendors. The many useful features such as Fast and Gigabit Ethernet, functions, and management capabilities of Ethernet make it the first choice for delivering new services over a common converged network infrastructure.

For free assistance in designing the right ethernet based solution for your network ….. including free rate quotes and pricing research … I strongly recommend taking advantage of the no cost help offered here:

“A company's supply chain network can be a complicated animal. To service this network of constant data sharing and storage requires a high performing reliable network backbone. An important part of the design is the right level of bandwidth support .... T1, DS3, or OC3 bandwidth circuits to be exact. Making the right decision on what circuit to choose means navigating a number of issues.”

* Meeting Your Bandwidth Requirements For Supply Chain Management Applications

"Deploying an Supply Chain Management (SCM) solution that provides the intended return on investment requires that the applications, servers, and enterprise network infrastructure work together seamlessly. This is easier said than done and will necessitate a thorough evaluation of your bandwidth needs to meet the demand."

* More On Meeting Your Bandwidth Requirements For Supply Chain Management Applications

"The key to a successful SCM implementation is a clear understanding of the business objectives and business requirements of the company the SCM primarily supports. This often includes a number of legacy systems which need to be integrated into the solution. From this will come the technical objectives to be met and the technical requirements that frame the solution. Only then will the communication requirements for bandwidth capacity, reliability, resiliency, latency, security, and expandability be meaningful."
