SDN: The emerging reality

Change is still afoot in Software Defined Networking, but it is now at least clear that SDN is here to stay, that SDN will be the way we build networks going forward. In this Network World Spotlight special report, pulled together by the editors of Network World, we analyze key developments and gauge where organizations stand today in their SDN planning.Inside you’ll find:* Controller Market Consolidation. There are still many types controllers available, but the market is rallying around OpenDaylight and the Open Network Operating System.* Crossroads for OpenFlow? Once conflated with SDN, OpenFlow progress seems to have stalled. Does OpenFlow still have a significant role to play?To read this article in full or to leave a comment, please click here

Router IP Traffic Export

Router IP Traffic Export (RITE), or simply IP Traffic Export, is a method of copying traffic directly from a router to an external device, such as a Protocol Analyzer or an Intrusion Detection System (IDS). This feature can be used to replace SPAN/RSPAN configurations deployed on L2 ports/VLANs. Two main benefits of RITE is, first, the ability to duplicate the traffic received on a WAN interface, such as Serial port, and second, granularity of our configuration – we can be very selective in what traffic will finally get copied from the network.

Before we discuss the configuration of RITE, just few words about limitations of this feature :

  1. The device receiving the exported traffic must be in the same L2 network as the router’s interface (e.g. must be directly connected). This interface is known as “outgoing” in the RITE’s terminology
  2. This (outgoing) interface must be an Ethernet port. Incoming interface(s) (where the traffic is received and optionally sent through) can be anything (e.g. WAN/LAN)
  3. Traffic generated by the router configured for RITE cannot be exported

A sample topology for RITE may look like one below. Our monitoring station (PC) is directly connected to R2’s RITE outgoing interface, Gig0/0 Continue reading

Android malware masquerades as Nintendo game emulator

A new family of Android malware adds insult to injury by making users pay for the data-stealing application.Palo Alto Networks found three variants of the malware, which it calls Gunpoder, masquerading as emulator applications used to play Nintendo games.Antivirus engines are having trouble detecting Gunpoder’s malicious code since it is packaged with an adware library called Airpush, wrote Cong Zheng and Zhi Xu of Palo Alto’s Unit 42 research group.“The malware samples successfully use these advertisement libraries to hide malicious behaviors from detection by antivirus engines,” they wrote. “While antivirus engines may flag Gunpoder as being adware, by not flagging it as being overtly malicious, most engines will not prevent Gunpoder from executing.”To read this article in full or to leave a comment, please click here

Oracle gets September trial date against Rimini Street

Oracle has been given a September trial date for its lawsuit against Rimini Street, which sells cut-price maintenance and support services to Oracle software customers.Oracle is seeking US$200 million in damages from the lawsuit, which targets Rimini Street and its CEO, Seth Ravin. A federal court judge in Nevada set the trial date last week, Oracle said Tuesday.The two sides are fighting over whether Rimini Street’s business model is legal, and observers say the case could establish ground rules for companies that provide maintenance services for other vendors’ software.The case is important for Oracle because the company gets a big chunk of its revenue from software maintenance contracts. Rimini Street provides services to customers of both Oracle and SAP for about half the rates they normally charge.To read this article in full or to leave a comment, please click here

Facebook to use all renewable energy in its next data center

Facebook is building a new data center in Fort Worth, Texas, that will be powered entirely by renewable energy.The company will invest at least US$500 million in the 110-acre site, which is expected to come online late next year.The new location will be the social-networking giant’s fifth such facility, joining existing data centers in Altoona, Iowa; Prineville, Oregon; Forest City, North Carolina; and Luleå, Sweden. It will feature equipment based on the latest in Facebook’s Open Compute Project data-center hardware designs, it said.For sustainability, the Fort Worth data center will be cooled using outdoor air rather than energy-intensive air conditioners, thanks to technology it pioneered in its Oregon location. Those designs are now offered through the Open Compute Project.To read this article in full or to leave a comment, please click here
