Meet SONiC, the new NOS (definitely not the same as the old NOS)

The open-sourced Software for Open Networking in the Cloud (SONiC) NOS is rapidly growing a community of developers and users that could change the way many networks are run by large enterprises, hyperscalers and service providers.The Linux-based NOS, developed and open sourced by Microsoft in 2017, decouples network software from the underlying hardware and lets it run on switches and ASICs from multiple vendors while supporting a full suite of network features such as Border Gateway Protocol (BGP), remote direct memory access (RDMA), QoS, and  other Ethernet/IP technologies.One of the keys to SONiC is its the switch-abstraction Interface, which defines an API to provide a vendor-independent way of controlling forwarding elements such as a switching ASIC, an NPU or a software switch in a uniform manner, according to the SONiC GitHub community site.To read this article in full, please click here

Should you be concerned about the Windows XP leak?

Reports hit the Web last week that the Windows XP source code has been leaked and posted to 4chan, one of the seediest boards not on the dark web.A link to a 42.9GB file was posted but quickly scrolled off. 4chan does not archive its posts so once the message scrolled off it was gone, but the link is getting around in other ways. The code is being hosted by Mega, a file-sharing service with its own dubious past.Reports from other sites say the code is legitimate. Microsoft has only said “We are investigating the matter."[Get regularly scheduled insights by signing up for Network World newsletters.] What is still unclear is whether the code is the whole codebase or just a portion. Those who have examined the code have said it covers Windows XP Service Pack 1, Windows 2000, and Windows Server 2003. The code has been circulating privately for years, according to the leaker. One theory is that the source of the code is an academic institution.To read this article in full, please click here

Streaming telemetry challenges SNMP in large, complex networks

Network telemetry is far from new, but its importance is growing as data volume and network size relentlessly snowball. Streaming network telemetry gathers operational data from various network devices, combines the information, and then forwards it for inspection and study.Growing scale and the increasing use of automation in next-generation enterprise networks require a modern, more efficient approach to network data capture and analytics, says Bo Lane, vice president of global engineering for Kudelski Security, a cybersecurity technology provider. "Streaming telemetry allows enterprises to track network state, identify network problems and optimize network performance," Lane says. "In modern software-defined networks, problems or bottlenecks may be identified and autonomously remediated in near-real time."To read this article in full, please click here
