Counterfeit Cisco switches/routers from Huawei may fall victim to Cisco exploit
Here is an interesting thought of 'what goes around comes around'. Think back to about March 2003 when Huawei Technologies said in court papers that it used some of Cisco Systems' source code in its routers. Although the Chinese manufacturer said the copying was inadvertent and involved far less code than Cisco claims. Huawei also said the offending code has since been removed. Cisco sued Huawei in US District Court for the Eastern District of Texas on 23 January, alleging that Huawei violated at least five Cisco patents and copied Cisco's Internetwork Operating System (IOS) source code, using it in the operating system for its Quidway routers and switches. Huawei's system contains text strings, file names and bugs identical to Cisco's source code, Cisco claimed at the time.
In Cisco's lawsuit it was also alleged that Huawei copied up to 1.5 million lines of software code. In its latest court filing, Huawei said an employee inadvertently used about 2 percent of the 1.5 million lines of code inside Huawei's VRP line of routers. Huawei, based in Shenzhen, China, has a wide reach in Asia and recently entered the US market, challenging Cisco on the pricing front. It's now working with Cisco competitor 3Com to deliver new networking gear to businesses.
