How can Latin American countries more quickly improve their Internet capabilities?

Latin America Advisor


Q: Many Latin American countries have lost ground in their Internet capabilities during the last year, according to the World Economic Forum’s recently-published ‘Global Information Technology Report 2014,’ which measures how well a country is prepared to use information and communications technology to create economic growth and improve well-being. No Latin American country cracked the top 10 and the regional leader, Chile, improved its score but still dropped one spot to 34th this year. What is behind the region’s poor showing relative to other regions? What specific policies or initiatives could governments or businesses implement to reverse the decline?


A: Andrés Maz, executive director of advanced technology policy at Cisco Systems: « There are successes at the country level, such as Chile, as well as steady improvements in Panama, Costa Rica and Colombia. However, many other countries around the world are improving faster in their networked readiness, and…

Transient Dialogues

The perennial metaphor of stagnancy, lack of innovation, poor leadership and mediocrity at all levels in the organization seems to have had a changing of the guard moment.
Microsoft, you have been ousted and the new ‘winner’ is Cisco Systems.

There are three things organizations need to keep an eye out for as they grow to avoid becoming a has been in innovation:

  1. Don’t let the high margins, growing revenue and cash on hand get you carried away. There was a time when Cisco was a behemoth when it came to cash on hand and the tech industry looked at it in awe. Seems that bad managers were left in awe to such an extent that by the time they came out of it it was too late and the damage of not moving quickly had been done.Don’t let a good looking…

Multiple Spanning Tree (802.1s)


The IEEE Multiple Spanning Tree Protocol (MST) is in essence an extension of the Rapid Spanning Tree Protocol (RSTP). MST allows multiple spanning trees to coexist on the same bridged network. A group of VLANs can be mapped to its own independent instance of spanning tree, this allows for design flexibility and better resource utilizaton.

MST was originally defined in IEEE 802.1s, and it is based on Cisco’s Multiple Instances Spanning Tree Protocol (MSTIP).  MST uses the same BPDU format as RSTP, therefore it is backward compatible with both STP and RSTP.

In order to understand MST, we must first define its components:

  • MST Region: A group of Bridges with identical MST Configuration Identifiers
  • Multiple Spanning Tree Instance(MSTI): Independent Spanning Tree topology defined within an MST Region
  • MST Configuration Identifier: The MST region name, revision number, and VLAN to MSTI mappings
  • Internal Spanning Tree(IST): Extends the CST inside an MST…
