SD-WAN – Will the Cloud Kill WAN Optimization?
SD-WANs are not WAN optimization. They solve a different problem from WAN optimization. And yet walking along the floors at the ONUG conference hearing about SD-WANs and service chaining, I couldn’t help but think that software-defined WANs (SD-WANs) are the death of WAN optimization in branch offices. WAN Optimization We started using WAN optimization at a time […]
Reduce MPLS Costs With SD-WANs With Better Resiliency
Reduce MPLS costs? You may wonder…”did I read that correctly”? You did. You can have a enterprise class WAN without MPLS, though connectivity to China is another story! New technologies are changing the way that many companies provision their wide area networks. WAN requirements are changing. All companies have: A continued need for more capacity An increased […]
Aryaka WAN – MPLS in India, China, Brazil in Two Weeks
I have read about the concept of the Aryaka WAN as a Service with a mixture of curiosity and doubt. At last, I can say that I have first-hand experience with Aryaka it is nothing short of marvelous. Imagine installing a global MPLS network in just two weeks, even connecting to India, China or Brazil! That is exactly what […]
DDoS Mitigation Cloud Vendors
In the last posting about DDoS Mitigation Solutions, I discussed how hardware vendors in the DDoS protection space differ. I highlighted how different companies process data differently using tap vs. flow, the advantages and disadvantages of ASIC vs. commodity CPUs, and the problem of DDoS protection from a scale perspective. The goal around hardware is performance, […]
Hybrid Networks – Selecting the Best Path for Any Application on the Network
The Hybrid WAN or Hybrid Network is the future of Wide Area Networking. As organizations adopt public cloud services and unified communications, network architects are looking for affordable ways to improve the performance and the availability of branch office connectivity. The current practice of connecting branch offices to a single MPLS connection leaves the office vulnerable to […]
Low Latency Solutions
When you are operating a global business, your WAN may carry applications that are particularly sensitive to latency. For example, financial transactions, voice and video are all very latency sensitive. The fact is, the physics of distance will always affect your network performance. But utilizing the best trans-continental cable system will make a big difference […]
Network Latency For Different Carriers
When you are evaluating carrier options for your MPLS network or IP transit, the network latency has a big impact on network performance. The use of Looking Glass servers allows you to view network latency for different carriers from one POP to another. Latency is not the only criteria in evaluating a network, since congestion, packet loss […]
WAN Acceleration Solutions- Best Practices
Businesses have become more dependent on IT Services delivered over Wide Area Networks to communicate over a geographically diverse enterprise network. Whether your WAN is based on MPLS, VPLS, or and IP-Sec VPN over the internet, optimizing network performance can offer a variety of benefits. Besides much better performance, WAN Optimization can control the growth of […]
Ethernet or VPLS for your WAN
We all use Ethernet as the network protocol of choice for our local area networks. For wide area networks, or WANs, the choices have been Frame Relay, ATM and MPLS. With Ethernet advantages like efficiency and low cost, carriers and users have embraced it as the future of the WAN. WAN speeds using Ethernet are currently into the multiple […]
Level 3 to purchase Global Crossing
This is not “new” news (from April, 2011) , but since many clients were not aware of this merger, I feel compelled to post it here: Level 3 Communications, Inc. (NASDAQ: LVLT) said it agreed to acquire Global Crossing Limited (NASDAQ: GLBC) for about $1.9 billion stock deal to boost its service portfolio. Including Global […]
