Community Networks Can Bridge the Digital Divide, But Some Still Need to Be Convinced
Community networks can help bring connectivity to many of world’s population still without it, but some governments, ISPs, and some potential users need to be convinced of their benefits, connectivity experts said.
Community networks can bring huge economic, educational, and social opportunities to areas without Internet access, Raul Echeberria, the Internet Society’s vice president for global engagement, said Wednesday.
With nearly half the world’s population still lacking Internet access, “this is creating a huge gap of opportunities,” he said during a community networking roundtable discussion hosted by the Internet Society.
Through community network projects such as a year-old network in the mountainous region of Tusheti in the nation of Georgia, the Internet Society has seen the proof that existing technologies can bring Internet service to some of the most remote areas on Earth, Echeberria said.
After a year of operation, the Georgian network is providing new economic opportunities to inn keepers and other tourism-related businesses in the region, said Ucha Seturi, director of the community network project there. Demand for Internet service is growing, he added.
With the technology questions largely solved, a key piece of the puzzle for community networks is getting the buy-in of the unserved communities and Continue reading
Thanks, Arista! We’ll Leave a Light on for You
Wow. Just, wow. Here we were at Pica8, ten days away from announcing a screamingly simplified white box switching architecture for enterprise campus networks – one that makes legacy switch stack and chassis switch replacement with disaggregated white box switches ridiculously easy — when Arista suddenly pops up and says that the success white box switches are having in the data center is now well and truly annoying to them, so they are starting to plan a future expedition to the enterprise campus in search of replacing lost revenue.
But after blowing straight past total market validation for us – we already have a number of ongoing enterprise campus network deployments inside some of Cisco’s oldest and largest accounts – Arista then went on to articulate the changes they envision for their future campus network switching push and, in doing so, came very close to a one-to-one mapping with what we’ve just announced as an orderable solution with our new PicaPilot switch orchestration software (see link below). (I really must order a case of champagne for my friends over there.)
Just how close is the mapping? Well, let’s start with solving the urgent requirement to simplify Continue reading

Regular Expression for Network Engineer Part-2
This post is continuation of the Regular Expression for Network Engineer Part-1 , here we have a look for the different methods to find out the pattern in string.
Findall() – returns list of all the matches the pattern in a string without overlapping
- EXAMPLE
[code language = “Python”]
re.findall(pattern, string[, flags])
In [118]: ip
Out[118]: ‘10.10.1.10,29.10.1.10,10.10.1.20,192.168.1.0,172.16.10.1,10.10.10.121’
In [119]: out= re.findall(r'(10.10.10.\d+)’ ,ip)
In [120]: out
Out[120]: [‘10,10.10.1’, ‘10.10.10.121’]
#Above example help us to find out all the IP’s of subnet 10.10.10.0/24 from group of ip’s.
[/code]
Match()-return a match object when pattern is found at the beginning of string, if no pattern is found ,result in None.
- EXAMPLE
[code language = “Python”]
In [189]: text
Out[189]: ‘Cisco IOS Software, 7200 Software (C7200-SPSERVICESK9-M), Version 12.2(33)SRE, RELEASE SOFTWARE (fc1)’
In [190]: out = re.match(r”Cisco”,text)
In [191]: out
Out[191]: <_sre.SRE_Match object; span=(0, 5), match=’Cisco’>
In [192]: out = re.match(r” Software”,text)
In [193]: out
In [194]: out = re.search(r” Software”,text)
In [195]: out
Out[195]: <_sre.SRE_Match object; span=(9, 18), Continue reading
