Cisco overhauls WAN optimization appliances

Five years after introducing its first WAN optimization devices, Cisco Systems Inc. is upping the range of speed and scalability revised.

“We are launching a portfolio of new devices with high performance and quality of experience for each application in a way that is very easy to implement for IT,” said Inbar Lasser-Rabb, senior director of corporate marketing for WAN optimization products.

Cisco makes the strongest of the six new units, which offers WAVE 8541, 2 gigabytes per second thanks to twice as fast as the WAN optimizer on the market. It can also be 150 000 TCP connections, a third more than any other competitor.

All new appliances, ranging in price from U.S. $ U.S. $ 235,000 in 6500, have two integrated Gigabit Ethernet ports and can upgrade to 10 GbE. Some models offer up to eight virtual slides together for added value services such as network analysis, two virtual slides in earlier models.

Important with the increase in data heavy applications like video and computer-to-computer data traffic optimization to a large network of increasingly, Lasser-Rabb said. Not only that organizations that want to maximize the bandwidth, they also want to optimize the performance of applications such as video – especially if they have virtual desktops.

The new devices also meet another concern, the ability to scale applications to hundreds of users.

The performance gains come in the latest version of the device “called Wide Area Application Services (WAAS). Version 4.4 includes, what did Cisco called context-sensitive eliminate data redundancy, Lasser-Rabb, can that compare and patterns that repeat in an application cache be -. For example, the colors in a PowerPoint slide if the blade is sent over the network, has WAAS, the cache memory to retrieve data.

“This can significantly reduce traffic,” she said, cutting knives 5 GB sent a T-1 connection from 120 seconds to 5 seconds.

The virtual slides an additional option on some models can be integrated with multiple WAN optimization services. One of the newest is the Cisco Systems Enterprise Content Distribution (ECD) allows certain devices to be simultaneously Wave 400 high-definition video stream uses to 150,000 units, said Cisco.

Cisco has not, until now known as a technology leader in the WAN optimization performance or been, said Paula Musich, Senior Analyst for networking products and chastity belts at Current Analysis. That changed. “I think correct, context-sensitive data redundancy is to be a hit with customers,” predicts. Also improves scalability “makes them competitive in the market.”
Zeus Kerravala, industry research analyst at the Central Committee, called the new models are a significant improvement in the first generation of devices Cisco WAVE. “It’s a big step forward.”
