Internet Key Exchange Version 2 (IKEv2)

A recent CISCO study published in Feb 2016 says that mobile data traffic has grown 4,000-fold over the past 10 years and almost 400-million-fold over the past 15 years. It forecasts that global mobile data traffic will increase nearly eightfold between 2015 and 2020.
Privacy and security become important and complex with the growth in data traffic.
Several Virtual Private Network (VPN) protocols like PPTP, L2TP/VPN, OpenVPN and IKEv2, SSTP, supporting different encryption technologies have evolved over the years. A comparative study of each of them can be found here.

IKEv2 (Internet Key Exchange version 2), referred as VPN Connect by Microsoft, is an IPSec based tunneling protocol that was jointly developed by Microsoft and Cisco. It is one of the few VPN protocols supported by Blackberry devices. Various, largely compatible open source implementations of IKEv2 are available for Linux and other operating systems.

IKEv2 is good at automatically re-establishing a VPN connection when users temporarily lose their internet connections such as entering and leaving an elevator. It supports the Mobility and Multihoming(MOBIKE) protocol, making it highly resilient to changing networks, which is extremely helpful for mobile customers. MOBIKE allows a mobile node encrypting traffic through IKEv2 to change point of attachment while maintaining a VPN session. That is, by using an IKEv2 protocol the user can lose their connection and reconnect to another access point without losing the VPN session! This helps users who switch between WiFi nextwork, hotspots and mobile data.

IKEv2 uses the IPsec Tunnel Mode protocol over UDP port 500, allowing the support for strong authentication and encryption methods. It encapsulates datagrams by using IPsec ESP or AH headers for transmission over the network. The message is encrypted by using encryption keys generated from the IKEv2 negotiation process. It also supports integrity checking algorithms like HMAC. All these things make IKEv2 very highly secure.

IKEv2 is considered at least as good as L2TP/IPsec in terms of security, speed, stability and the ability to establish (and re-establish) a connection.

Draytek routers support LAN to LAN connection (like Microsoft Azure cloud operating system to your network) through a virtual private network (VPN). They also support Host (Windows/Android/iOS) to LAN connection via VPN.

Get technically trained in Open Source IP Telephony – an area in high demand

Practice makes a man perfect. Any person can rise high only if the person has the will and stamina to perform well in the area of work. The question is, how can that perfection be achieved, that is, where can a person get the desired practice? This practice can be well achieved from places which provide the required training in the area in which expertise is required.

What is technical training?

There are a number of institutes providing technical training in a variety of fields. Whether it be training in the air force or technical training in programming languages for application development, one will never fall short of options. A number of technical training institutes are quite efficient in providing training for skill requirements. These acquired skills can then go a long way to avail many opportunities.

A major area to take to get trained in

A major advancement in the area of telephones is the recent asterisk, which is a protocol for better communication. It uses voice over IP so that the cost of communication is remarkably reduced and also made more secure. Voice over IP is an area which has a bright future. With its introduction, it has completely revolutionized the telephone arena. Thus getting a technical training in areas like this will go a long way.

The open source telephony provides a method for custom communication. These reduce the cost of calls by making the crossing over the PSTN to be minimal. In this era, where electronic communication is the basis of many applications, cost reduction in the communication zone is very beneficial and hence in demand. Thus, a number of people are going for training in the asterisk – a major part of voice over IP.

Training is beneficial to the one trained as well as the software

In the technical training, one is taught to develop the software which enables the entire process. The software for efficient communication for voice over IP or open source telephony is quite new and advancements in this field are quite possible. So the larger the number of workers in this area, the better progress it may be able to face. Also, the fact that this is an area which is in high demand, getting a training in this assures one to be important and wanted in major companies.

A person who is technically trained can not only work make updates and modifications on the software but perform good maintenance functions too. The technical training also provides people the knowledge to keep the voice over IP mechanism working well. They can also correct any bugs or problems that may be experienced by its users.

Lastly, a technical training in the field one has interest not only makes the interest grow stronger but gives one an opportunity to work with things which are truly close to one’s heart. In such a case, getting a technical training can change the perspective of a prospective employer. The training will provide proof of the knowledge held by the applicant and the individual’s own interest can take one a long way.

7 Key Questions You must answer before moving to VoIP.

The impending ISDN switch-off is now putting the pressure on businesses to transition to all IP telephony. You may have already come across information about the benefits of VoIP, and the great news is that most of the claims you see, if not all of them, are true! VoIP can lower your monthly communications costs by as much as 50% and can greatly improve the way you communicate internally and externally, solving many business communication pitfalls.
The real challenge for you is to decide how to implement IP for your specific needs, and to understand the risks involved and how to handle them. It is important to get all the facts straight about moving to IP so you can ensure a smooth migration instead of an expensive mishap.
We’ve come up with 7 key questions to ask when making your plans to move to all IP.
1. Is your system secure?
You should never have to open holes in your firewall to get VoIP up and running. Ensure your system of choice will be implemented without risk to your network. Once your VoIP system is set up, you should be confident that it is protected from hackers and spyware. Be sure to give high priority to security management.
2. Is your system scalable?
VoIP technology is great for scalability, but you still need to get the basics in order. When your resellers or suppliers ask you about the number of simultaneous calls you expect to receive, they are trying to determine what solutions will best suit your needs. For example, you will need to decide between an SIP trunking plan and a hosted PBX. It is important to know your long term business communication strategy so you can set up the most efficient IP solution.
3. Do you have a disaster recovery plan?
Reliability is essential with any system — especially business VoIP. If you have only one data center and it goes down, or if you have an equipment failure, you will lose your vital voice communications. Having disaster recovery plans in place is always wise.
4. What uptime guarantee does your system have?
If the number is anything less than 99.99%, then you have a problem. 99.99% is equivalent to 52 minutes of annual downtime, and for most businesses, this will be sufficient. Seek a solution that is reliable and able to meet the needs of your business. Remember, your system is only as reliable as its weakest link.
5. What happens if your IP phone is unreachable?
If missing a call can mean a critical loss of business to you, then make sure your system will automatically forward calls to another system. The mobile phone is a commonly used backup. With IP telephony, you can be reached at any time and any place if you properly configure your system. Ensure your solution is set up to provide you with the level of connectivity you need.
6. Are all your existing phone features supported?
IP phones can do so much more than traditional systems, but you need to ensure they do what’s right for your business. What features do you need? Be sure to ask before you choose a VoIP system. Next, make sure everything has been configured correctly and that your staff members have been trained to utilize all features.
7. Which fax services are supported?
Faxing over VoIP can be both challenging and temperamental. If your business regularly utilizes the fax machine, make sure you have a working fax service within your specifications. Some providers offer faxing services, and some systems provide fax to email. Ask about faxing and get any issues resolved before moving to all IP, as this can prevent unexpected problems.
