Cisco Reacts to Reactivity

Cisco Systems Inc. (Nasdaq: CSCO) is continuing its push into applications territory, announcing today a bid to acquire Reactivity Inc. , a vendor of XML-processing appliances.

The $135 million cash deal is expected to close by the end of April. Reactivity's 56 employees would be folded into Cisco's Datacenter Switching and Security Technology Group, headed by senior vice president Jayshree Ullal. (See Cisco to Buy Reactivity.)

Cisco will continue offering Reactivity's gear, but it's also eyeing the possibility of applying Reactivity's technology to other gear to provide WAN acceleration and security.

It's all part of the push by Cisco and others to create application-aware networks. As more applications come to use XML as their language for sending information, networking gear has had to add XML processing to its duty roster.

For carriers, XML is a keystone to service-oriented architectures (SOA), where an enterprise converts its operations into Web-based services. (See XML Networking's Carrier Appeal.)

So continues an XML mini-frenzy that popped up in 2005, when Intel Corp. (Nasdaq: INTC) bought Sarvega and IBM Corp. (NYSE: IBM) grabbed DataPower. (See Intel Absorbs XML Startup and IBM Plugs Into DataPower.)

Cisco had made its XML move months before that with its Application-Oriented Networking (AON) strategy, which was followed up a year later by its Service Oriented Network Architecture (SONA). (See Cisco Speaks Applications and Cisco Everywhere: Meet SONA.)

Both strategies involve making the network more aware of applications. At the time, though, companies like IBM were already working the opposite route -- giving applications more intelligence about the network.

For its part, Cisco says the Reactivity deal doesn't signal a strike at anyone like IBM. "We are focused with this technology on players we compete with in the application switching market," says George Kurian, vice president of Cisco's applications delivery business unit. Presumably that means the Layer 4 through 7 companies like F5 Networks Inc. (Nasdaq: FFIV) or Packeteer Inc. (Nasdaq: PKTR), although Kurian wouldn't name specific competitors.

Still, others see Cisco inevitably finding new competitors as it gets into new areas like XML. "Clearly, Cisco is more and more in the battle against some of the server and software companies in the data center," says Bill Choi, an analyst with Jefferies & Company Inc. .

Any real clash between the likes of Cisco and IBM is still years away though, Choi says. In part, that's because data center virtualization hasn't caught on. Choi believes the idea has won over a few large enterprises but hasn't become widespread.

As for where Cisco's XML technology has been coming from, the company's used Layer 7 processors from Tarari Inc. Neither side appears to have ever announced this, but the deal was well known in the industry; Reactivity even remarked on it in a press release. (See Reactivity Welcomes Cisco.)

Reactivity has announced it's using Tarari, so the chip maker's relationship with Cisco doesn't appear to be in jeopardy.

re: Cisco Reacts to Reactivity Presently the primary foundation for the network is the Internet Protocol. It is well known for quite some time that a good platform to build on top of the bare IP transport network is an XML layer. Cisco is making good on that additional intelligence promise. Remains to be seen how the others, namely Juniper, etc., will react.

re: Cisco Reacts to Reactivity Craig:
XML's universality comes from the X: eXtensibility. Even if other languages such as JSON come about, it seems like XSLT will be able to assist in any such syntactic transformation. See http://jsonml.org.
Thus, XML is a good first bet for integrating application-level intelligence into the network.

Can some mathematician in the NetLand chime in regarding this matter (of universal applicability of XML)?

re: Cisco Reacts to Reactivity So what if XML is human-readable? Yes, that makes it less bandwidth efficient, but the time has come to waste some of the ever-increasing bandwidth to create another abstraction layer that saves application development and operations costs. Video is on its way to becoming the dominant bandwidth driver, so mere 'data' will become cheap to transport, even if it's bloated by past standards.

re: Cisco Reacts to Reactivity Good point, krbabu.

Now, weren't there some questions around the pervasive use of XML? It's a language meant more for human eyes than for machines, and I know that was concerning some people a few years ago. Haven't kept up on that debate, I'll admit -- how do you folks feel about XML becoming a universal apps language?

re: Cisco Reacts to Reactivity The problem with putting L7 semantics into a network is that they tend to change with time. If you want to quickly process packets or XML commands or what ever, you probably want to codify them into hardware. That does not mix well with a changing standard, which I believe is one reason L7 has been separate historically. Software people do not think like hardware people. Things change, so what? I think this will become an issue with time.
