EMBC readies deep packet inspection specs

Ultimately, the industry needs a range of benchmarks to handle differences such as the types of cores used and whether they support multi-threading, said Joe Byrne, a senior analyst with market watcher, the Linley Group. But initially, "anything is a step forward because we do have a lack of clarity," said Byrne.

Indeed, Cavium, NetLogic and Freescale are battling it out with processors that use very different kinds of cores and multi-core implementations. The benchmark "is one of the more challenging things we have done in EEMC because it involves the processors, systems and even software stacks for them," said Markus Levy, president of EEMBC.

The working group is seeking the widest possible review of its draft and is still open to new members. "We want to make sure everyone can work through their issues," said Caldwell.

The final spec is likely to have several different levels of certification. They will cover systems ranging from home routers and gateways scanning for 512 virus signatures to central office systems that check for as many as 100,000 signatures.

The group is likely to recommend changing on a regular basis exactly which group of viruses and malware programs are embedded into test data flows when running the benchmark. "If we only test for certain viruses, vendors could optimise for them," said Caldwell.

"One of the controversial issues here is how to balance standard stability with the changing nature of viruses," said Levy.
