Recent Cisco news highlights two prominent service providers – Deutsche Telekom and Telefonica – who have chosen Cisco IP Next-Generation Network solutions.
Deutsche Telekom subsidiary Hrvatski Telekom – Croatia’s largest telecommunications company – is using Cisco solutions in its new TeraStream cloud-enabled IP architecture.
Key elements include all-IPv6 streamlined routing architecture; fully converged IP and optical layers with 100G coherent technology; integrated cloud service centers, enabling virtualized network services and applications for rapid service innovation; programmatic interfaces aligned with the software-defined networking architecture for real-time automation and OSS; and customer self-service management capabilities.
Cisco has delivered the following technologies in this landmark deployment:

So, lets dig into LISP Routing a little more. If you have not done so, I would recommend you read my first post, since I am not going to review the concepts here. In this post, I am going to break things down into three steps: 1) how packets are forwarded (i.e. the data plane operation), 2) how mapping information is propagated (i.e. control plane operation), and 3) how we internetwork with non-LISP locations.
For starters, lets head into the weeds and take a look at the LISP header format. In the last post, I mentioned there is some flexibility in how handles IP addressing. The two examples below show a couple of scenarios: pure IPv4 and a IPv4/IPv6 hybrid:

When Cisco announced the CRS (Carrier Routing System) in 2004, many analysts and other observers thought it overkill. Some said that Cisco would not sell more than 50.
To date, the number is greater than 8000.
That would seem to fall into the category of “Exceeding Expectations”.
And just how did Cisco do this? In part, by continually staying ahead of the game with enhancements – never waiting for traffic loads, customer demands or other circumstances to force it into catch-up mode.
Today, Cisco continued that practice with further enhancements to the industry-leading CRS platform.
Cisco announced that GTS Central Europe (GTS CE), a leading provider of integrated telecommunications solutions and data center services in Central and Eastern Europe, has deployed the CRS for its Next-Generation Internet core. Cisco new elastic core networking capabilities enable service providers such as GTS CE to cost-effectively launch and scale revenue-generating services within minutes instead of months. The solution includes the industry’s first integrated coherent 100 Gbps IP over DWDM and Cisco’s nLight™ technology for the CRS.
Cisco’s nLight technology converges IP and optical transport networks by introducing programmability to minimize network complexity while maximizing service intelligence and monetization opportunities. This capability significantly reduces network total cost of ownership and is a key element of the Cisco Open Network Environment (ONE) framework.
Also, in recent related news, Cisco and BT recently conducted a landmark 100G DWDM trial

On August 29, I’ll be joining Zeus Kerravala of ZK Research for an on-line briefing on his research regarding Cisco and Microsoft Unified Communications products and services. While making my preparations for the webcast it got me thinking about how customers should approach Unified Communications strategies, investments, and projects irrespective of any vendor-related decisions. In discussing Unified Communications solutions with customers, I recommend that they keep six success factors firmly in mind in charting course for highly effective solutions. Read More »

An IP Address Management (IPAM) solution is not just a repository for IP addresses. The simplicity and thoroughness it offers makes for a powerful tool that increases the efficiency and reliability of networks while substantially reducing operating expenses:
- Automation of Processes: Tasks that administrators don’t have to manage manually result in direct management time and operating expense savings.
- Simplification of Processes: Reducing the Read More »
