The answer to your networking needs? Heavy-duty applications from the likes of Oracle, SAP and Siebel, not to mention run-of-the-mill email, are putting a strain on wide area networks. Is it any wonder, asks Stewart Baines, that network managers are increasingly turning to IP virtual private networks? While cost management initiatives continue to dominate corporate IT spend, IP VPNs are increasingly becoming the most important strategic wide area connectivity priority for businesses small and large. That IP VPNs can lower operational costs - along a demonstrable ROI curve - but can also add a great deal of extra flexibility into the way a business works, is a double whammy for IT buyers eager to shine. IP VPNs are becoming must-haves on many strategic IT reviews because they can help businesses deal with changing working patterns like teleworking, while supporting widely distributed applications and data repositories and extending the enterprise to their customers and suppliers alike. … [Read more...] about Convergence: lower costs and extra flexibility

You may be surprised to hear it's a debate about more than technicalities such as IPSec and MPLS IP VPNs are now perceived as secure, so what are companies using them for? As Simon Marshall explains, location, maintaining control and an old application called voice are all key issues... So you decide you want to reduce costs or support remote users by integrating an IP VPN into your convergence strategy. Yet you're worried about becoming a fashion victim. After all, your competitors seem to be doing the same thing. Your confidence is undermined. That is unless, of course, you can make the case that IP VPN support for your apps is growing and that a maturing managed service approach from telecoms providers is the way forward. Well, probably the first point to note here is that IP VPNs are actually happening after years of talk. "IP VPNs are coming off the business wish list, and there are a number of companies beginning to seriously examine their infrastructure for data and voice," … [Read more...] about What are IP VPNs good for?
In the 90's as we pondered the future of data networks, we came to the realisation that as most applications were based on IP, it made sense to offer IP-routed data connectivity for Wide Area Networking (WAN) solutions. The IP die had already been cast by via internet with the value proposition of private IP networks - typically MPLS-based - to provide the flexibility of the Internet via a private network model. MPLS has been an extraordinarily successful solution in the corporate WAN market - providing a platform for application convergence, supported by performance SLA's spanning packet level attributes such as delivery ratio, latency/round trip delay, jitter and availability. As a private IP network, MPLS provides peace of mind around security, but also as a managed network infrastructure, comfort that if there is an issue the matter can be resolved by a single accountable provider. Interestingly, as MPLS has evolved over a 15+ year lifecycle, the internet has "lurked" in the … [Read more...] about Internet for WAN. Is it real this time?
About 20 years ago there was a big wave of networking innovation, spurred by the Internet age. It gave birth to huge networking companies like Cisco, Juniper, and Ericsson. Then, the pace of innovation just kind of stagnated. However, the recent acquisition of Viptela by Cisco at $610M and even more recent acquisition of VeloCloud by VMware at an estimated (whopping) value of $1.4B have changed the game, and they definitely suggest that virtualisation is setting the networking market on fire again. During the time when data centres were undergoing the revolutionary transformation to cloud, the networking industry basically skipped this entire evolution. Which begs the question, why? From the internet age to the cloud Starting in approximately 2011, the second wave of major transformation began to present itself in the networking industry, starting with major acquisitions like Cisco with Tail-f, and VMware’s acquisition of Nicira—leading to a world where the service and … [Read more...] about Is networking becoming cool again?
IPv6 will go fully live on June 6. That's the date when 50-plus access networks and more than 2,500 websites -- including Google, YouTube, Facebook and Yahoo -- will turn on support for the long-anticipated upgrade to the Internet's main communications protocol and leave it on for good.World IPv6 Launch Day is being coordinated by the Internet Society, which is promoting IPv6 as the best strategy for ensuring that the Internet continues to grow as address space becomes increasingly scarce with IPv4, the original version of the Internet Protocol.

Comcast has moved into the next phase of its IPv6 roll-out, becoming the first U.S. broadband ISP to enable next-gen Internet services for residential customers that use home gateways.Comcast plans to announce its IPv6 service for home gateway users later this month, but company officials released a few details about this service at the North American IPv6 Summit held here this week.John Brzozowski, chief architect for IPv6 and distinguished engineer with Comcast, said IPv6 service was already available to home gateway users in two U.S. cities. The service is available for residential customers that use one of six home gateways, which are specific IPv6-enabled models from D-Link, Linksys and Netgear that are listed at this Web site."When we launch this service in an area, we are instantly seeing IPv6 traffic among home networking users that have IPv6 turned on by default," Brzozowski said.MORE: Comcast expands IPv6 into four more statesComcast is providing home networking users with … [Read more...] about Comcast is First U.S. ISP to Offer IPv6 to Home Gateway Users

Here are steps you might follow to implement MPLS.1. Number of sites and bandwidth to each.2. Devices and device configurations.3. Your applications. How many applications do you have? What are they? How often are they used, and by whom?4. Application characteristics. Describe the network characteristics of your applications. Are they store-and-forward (i.e., latency insensitive)? Or interactive? How “chatty” are they? In typical usage scenarios, how much bandwidth do they consume? How does that vary by time of day/week/month/year?5. Other networks. Be sure to include applications that may be on other networks — particularly video and voice). You’ll want to document your current and planned voice, video and conferencing use.6. Future plans.

In February 2011, the global Internet Assigned Numbers Authority (IANA) allocated the last blocks of IPv4 address space to the five regional Internet registries. At the time, experts warned that within months all available IPv4 addresses in the world would be distributed to ISPs.Soon after that, unless everyone upgraded to IPv6, the world would be facing a crisis that would hamper Internet connectivity for everyone. That crisis would be exacerbated by the skyrocketing demand for IP addresses due to a variety of factors: the Internet of Things (refrigerators needing their own IP address); wearables (watches and glasses demanding connectivity); BYOD (the explosion of mobile devices allowed to connect to the corporate network); and the increase in smartphone use in developing countries.

Botnets made up of hacked home routers were used to launch distributed denial-of-service attacks against the five largest financial organizations in Russia.The attacks occurred on Monday, Dec. 5, and were detected and mitigated by Rostelecom, Russia's state-owned telecommunications company. The attacks peaked at 3.2 million packets per second (Mpps) and the longest attack lasted for over two hours, Rostelecom reported Friday.The company did not provide a bandwidth measurement for the attacks, but 3.2Mpps is not that much. DDoS mitigation providers regularly see attacks that exceed 100 Mpps and a very large September attack against the website of cybersecurity blogger Brian Krebs peaked at 665Gbps and 143Mpps.This week's DDoS attacks against the Russian banks used the TCP SYN flood technique and originated from hacked home routers, according to Muslim Medzhlumov, director of Rostelecom's cybersecurity center.A common trait for these routers is that all of them were using the CPE WAN … [Read more...] about Attackers use hacked home routers to hit Russia’s 5 largest banks
