VIGOR - Menghubungkan FXS ke PSTN PBX


As everybody knows, FXO interface of VoIP devices is suitable for connecting to the PSTN-PBX in order to expand the amounts of extensions. The Vigor VoIP routers with FXS interface also provide useful ways to implement the similar utilization. The following are two typical application scenarios.

Case1. Calls from VoIP to extension.

1. David dials the VoIP number of Vigor2900V(A).

2. After connection success, presses Linda's extension 610.



Case2. Calls from extension to VoIP.

1. Linda presses prefix number (e.g. "7" ) firstly to choose exterior line - FXS of Vigor2900V(A).

2. Then dials David's VoIP number of Vigor2900V(B).



Note : PSTN-PBX is widely adopted by most AnnexA countries. Because most AnnexB countries such as Germany, Norway and the Netherlands have encouraged small offices to deploy ISDN PRI into PBX, PRI PBX are quite popular at offices located in Germany, the Netherlands and Norway.

Choosing the Right 11N

The good news: the 802.11n specification offers a lot of different configurations from 1- to 4-stream options, operation in either or both the 2.4 and 5 GHz bands, and a variety of optional features like spatial multiplexing and 40 MHz mode.

The bad news: while choice is great, the array of options makes it difficult for customers to choose the right combination of features for their products and for consumers to select for their personal use.

As a leading developer of 11n solutions, Atheros suggests the following considerations when selecting the right combination of 11n features for our customers' products and their end users' selection.

  • What applications with what bandwidth requirements will the product support? Simple data functions like email, web browsing and downloading YouTube files or high-definition videos and playing high-resolution video games?
  • Where will the product be used most often? Home? Office? On the go?
  • Will interference from other devices— household products like microwaves and baby monitors— be an issue?
  • How many other Wi-Fi®-enabled devices will operate in the product's environment and compete for the available wireless spectrum?
  • Will the device need to connect at long range (more than 100 feet from the router or other devices in the network) or not?
  • What is the desired price range of the product?

Here are some rules of thumb that we've devised to help our customers make the important feature decisions for 11n.

More streams equals more bandwidth.

Each stream offers up to 150 Mbps PHY rate of bandwidth. Currently, Atheros offers solutions in 1-, 2- and 3-stream configurations. While a 4-stream configuration could yield up to a 600 Mbps PHY rate, we currently do not envision a commercially viable 4-stream option that provides greater real-world performance than 3-stream.

The greater the number of streams, the greater the rate-over-range.

Typically, what matters most in Wi-Fi products and networks is the usable rate-over-range, because RoR is the amount of bandwidth that's available at connection points within the user's environment. The greater the RoR, the greater the coverage of the home, office or at mobile locations like hotspots.

2.4 GHz, 5 GHz or Both?

2.4 GHz is a narrow, relatively crowded band of 3 non-overlapping wireless channels

  • Good for data functions like email, browsing, data file transfers, standard definition video applications like YouTube, audio transfers, low-res gaming
  • Good in environments relatively free of interfering devices such as microwave ovens and baby monitors

5 GHz is a wide, clean band of 24 non-overlapping channels

  • Good for functions that require no/low latency such as HD video, real-time, high-resolution video gaming
  • Better for environments fraught with interference from other networks and household devices

Dual-concurrent, dual-band

  • Today's networks and consumer electronics products increasingly employ the best of both worlds with dual-concurrent 2.4 and 5 GHz, offering 27 aggregate unduplicated wireless channels that enable network management, allocating the 2.4 GHz band for data-centric applications and 5 GHz for multimedia

It's all about the app

The applications that will be handled by a router, consumer electronics device or computer have a big impact on which 11n is needed. Here are some apps-based suggestions for applicability of a particular 11n solution.

11n for home applications

In the office

Simple "rules of thumb" to 11n selection

Align 1-stream, 2.4GHz:

  • Great for data apps like email, browsing, SD video,
  • In relatively uncrowded networks
  • Bandwidth required "close in", wide area coverage not necessary

XSPAN 2-stream, 2.4GHz

  • Good for data apps, SD video and single HD streams
  • In relatively uncrowded networks
  • Bandwidth required at longer range (for instance, multi-room networking in the home)

XSPAN 2-stream, 2.4GHz/5GHz

  • Great for data apps, SD video and single HD streams
  • Great for environments where network interference is likely
  • More bandwidth needed in multiple rooms
  • Dual-band network for enhanced multi-device support

XSPAN with SST3, 2.4GHz/5GHz

  • Best for latency-sensitive applications like HD streaming video and real-time, high-resolution gaming
  • Support for multiple devices, multiple applications
  • In environments where interference is likely
  • The best coverage of the entire home or extended office area with the highest bandwidth

Survey Finds Strong Support for Educational Technology

By Leila Meyer 03/14/11

Most educational leaders around the world support technology in
education and believe it is increasingly transforming teaching and
learning, according to an international survey commissioned by Cisco
and conducted by Washington, DC-based Clarus Research Group. The
survey revealed that education is transitioning to the new "connected
learning" networked economy, which requires technological skills
development for increased global competitiveness in education.

Clarus conducted telephone interviews with 500 educational
administrators and information technology decision-makers in 14
countries across five continents. Half of the respondents were from
K-12 schools, and the other half were from colleges and universities.

The majority of people surveyed indicated they see potential for
technology to improve student employment prospects, distance education
opportunities, student engagement, communication and collaboration,
and research capabilities. Most also said they see technology as a way
to reduce costs. However, online security rates high on the list of
concerns.

The three teaching and learning issues affected by technology rated
most critical were teamwork and project-based learning, student
engagement, and preparation for the workforce.

Eighty-six percent of respondents indicated a need for programs and
curriculum that help students develop teamwork skills. The survey
concluded that increased availability of collaboration tools is
helping to foster teamwork and project-based learning.

Eighty-five percent of respondents reported they believe technology
plays an increasingly large role in student engagement and
participation. They said most students seem to enjoy using technology
in the classroom and also indicated technology enables teachers to
tailor lessons to the needs of each student, rather than leave some
students behind or pace teaching for the slowest learners. Teachers
who have used computers to teach math, for example, found that the
technology allowed students to progress at their own pace while also
freeing the teachers to spend more time with students who needed extra
help.

Eight-three percent of respondents considered educational technology
critical to preparing students to compete in a global economy and
ensuring their employability after graduation. Those surveyed said
technology must be incorporated into the core curriculum so students
will be ready to engage in the increasingly connected "workforce of
tomorrow" that requires them to understand how to use technology
effectively.

Other issues of importance identified in the survey included:

Using technology to improve communications with students, parents,
faculty, and staff;
Protecting students from Internet abuse;
Strengthening on-campus data security;
Using "presence" technology in teacher training and staff development;
Using technology to reduce administrative costs and improve cost-efficiency;
Embedding video and multimedia in the learning process;
Investing in data-driven assessments and decision-making systems; and
Expanding online international education.

The priorities of survey respondents varied by region. Those in the
Asia-Pacific region focused on improved communications with students,
improved research infrastructure and capabilities, and preparing the
workforce of the future. European respondents focused on funding,
online security, international presence, research infrastructure and
capabilities, and online international curricula. Respondents from
emerging markets focused on preparation for a global economy, student
attendance, and employability. Latin American respondents had the
highest hopes overall for educational technology and its positive
effects on society.

MySQL Semi-Synchronous Replication. See the Magic. Try the Magic.


Overview

MySQL Replication is one of the most used and valued features of the MySQL Server.

Unlike some other products on the market, it's out-of-the-box, easy to configure, non-paid and smart features.

Most of our medium/large/super-large installation base are using replication to achieve "scale-out" scaling. Some will use it for backup purposes (not as HA though) and some will use it for geographic redundancy.
In this article I won't discuss replication as there are hundreds of posts out there on how and what replication can do for you.

Rather, I would like to discuss our new extension to the good old replication mechanism: Semi-Synchronous Replication.


Before I go on, I think I should define "Semi-Synchronous Replication". What is "Synchronous" and why it's only "Semi".

Asynchronous VS. Synchronous

  • Synchronous: Every write transaction (insert, update, delete) is replicated to the slaves immediately, and the transaction is not considered complete, until all slaves reply they have received the data (and maybe even flushed it to disk).
    If even one slave replies with failure, the transaction will rolled back from all the servers and the failure will be communicated to the application.
    Usually, the master is well aware of all its slaves.
    • Pros: Redundancy; we're sure the data safely resides in more than one server.
    • Cons: Performance; each transaction takes time till all slaves and the master acknowledge the transaction is replicated and complete.
  • Asynchronous: The write transactions will be written to the master disk and to some kind of replicating log (in MySQL it's the "binary log"), the application gets acknowledgement that the transaction is complete even though the slaves have not received the data yet.
    The slaves, on their own time, access the master and retrieve data they need to replicate, since the last time they accessed the master bin log.
    That means the master doesn't "know" about the slaves nor how far behind they are, or even if they are still replicating.
    • Pros: Performance; the transaction waits only for the master to flush and acknowledge.
    • Cons: Redundancy; we have no idea whether the data is on all the slaves, some of the slaves or maybe on none of the slaves.

Get the picture?

This is one of the basic trade-offs of "Performance VS. Redundancy". You cannot get both. Never.

That is, until now… Our development guys came up with a great idea combining both.

Async Replication you get via MySQL out-of-the-box replication.

Sync Replication you can get with DRBD and Linux-HA.

SemiSync you get if you install MySQL server 5.5 and later.

So what Semi stand for?

In SemiSync replication, the master holds the transaction the same way it does with Sync replication, but it waits only for one of the slaves to acknowledge.

The acknowledgement from the slave means, it has received the transaction and applied it to the relay log and flushed it to disk. It doesn't mean the data has actually gone into the database.

Just to make this statement clearer, it means the transaction was written to the relay log, and the relay log was flushed to disk.
There is still the need for the SQL thread to pick it up and apply it to the database. It's very unlikely not to complete this task, but that way we're getting a bit more performance.

As soon as the master receives the acknowledgement it will complete the transaction and reply to the application.

This article will show you how it works. As I try to keep my posts as hands-on as possible, this one will include lots of code blocks as well.
