We propose a notion of causal influence that describes the ‘intrinsic’ part of the contribution of a node on a target node in a DAG. By recursively writing each node as a function of the upstream noise terms, we separate the intrinsic information added by each node from the one obtained from its…
Given a node-attributed graph, and a graph task (link prediction or node classification), can we tell if a graph neural network (GNN) will perform well? More specifically, do the graph structure and the node features carry enough usable information for the task? Our goals are (1) to develop a fast…

HP again is beating the network management drum with software updates the company says will unify many facets of management as well as automate problem diagnoses and troubleshooting.
Network World’s DEMO show is the place to go to see the absolute hottest technologies. And you really do have to see them. We gave Jason Meserve and Keith Shaw a video camera and a microphone. They lounged by cherub-encrusted fountains and in leather chairs. Keith looked for a job. And when they weren’t too “busy” they managed to bring us some pretty cool demos.

SBC named Alcatel as its primary network infrastructure and services supplier for Project Lightspeed, SBC's $6 billion fiber-to-the-node buildout. The deal is worth $1.7 billion to Alcatel over five years. Alcatel will provide access and fiber technologies, IP routing and Ethernet switching systems, and network systems integration services. Additionally, Alcatel will work with SBC on video systems integration. SBC's FTTN project is intended to deliver IPTV, high-speed broadband services, IP voice and wir
As businesses incorporate more interactive and dynamic content on their Web sites, it becomes harder to ensure that end users and potential customers can access that content quickly. A new service from Limelight Networks aims to take some of the guesswork out of Web site delivery. Last week the content delivery network (CDN) provider launched LimelightSITE, a hosted service designed to accelerate Web site content and provide a consistent Web experience http://www.networkworld.com/community/node/28383 for e
SBC is reportedly lining up Alcatel and Lucent to help kick start its $6 billion Fiber-to-the-Node project, a development that could give the vendors the inside track in supplying equipment for the buildout.
Yet another sign that VoIP is taking over the world: Ford has ordered a whopping 50,000 IP phones for 110 company facilities in southeastern Michigan. In an interesting arrangement, SBC will design the IP voice system and then manage it for Ford - while Ford continues to manage the IP network itself.

Further preparing its software for production use, Eucalyptus Systems has outfitted its private cloud software with the ability to keep running even if an individual node fails, a feature called high availability (HA), the company announced Wednesday.
On the heels of unveiling its new multi-service edge router, Nortel made another significant move at the edge with an upgrade of its six-year-old Shasta IP services switch. The Services Edge Router 5500 more than doubles the performance and density of the Shasta Broadband Services Node 5000. It supports twice as many IP VPNs - 4,096 - than the 5000, Nortel says, and more than twice as many subscribers: 72,000 vs. 32,000. The quarter-rack chassis of the 5500 features 14 slots for control and management, swi
Last week, Siemens Information and Communication Networks announced the upscale HiPath 8000 Real-Time IP System. Supporting up to 100,000 users per node, the hosted system can be deployed and managed from a data center.
