At Arista Networks, the status quo inspires us to innovate and continue our mission to reinvent the network – from cloud to client. Today, we’re continuing that journey – into the campus network. Let’s face it; the legacy three-tier architecture of access-aggregation-core is wasteful and oversubscribed – creating a perfect storm for market transitions and Arista innovation.

The last 40 years have seen tremendous growth and progress in the data networking industry. Ethernet, IP, MPLS, GRE, IPsec, MACsec, and VXLAN enable operators to build secure, multiservice, high-performance data planes that interoperate across multiple vendors, multiple operators, and multiple administrative domains. Likewise, BGP, OSPF, IS-IS, LDP, RSVP, BFD, LACP, L3VPN, VPLS, and EVPN enable operators to build scalable multi-vendor control planes that federate across organizational boundaries, supporting mission-critical networks with global reach.

CRI-O was launched as a lighter alternative to using Docker as the runtime for Kubernetes.
Nimble platforms now support Storage Class Memory (SCM) and NVMe for super-fast, low-latency flash storage.
A reader recently emailed me with this question: Why isn’t the condition for a Feasible Successor set to less than (<), rather than less than of equal (<=), in EIGRP? It certainly seems, as noted in the email, that this rules out a lot of possible possible loop free alternate paths. The network below will be used to illustrate.
First, assume all links are cost of 1 except D->C, which is cost of 2. Here D will choose B as the Successor, and the FC will be set to 2. The RD of C will be 1, so C will be an FS. Now consider two failures. The first failure is D->B. D will immediately reroute to the FS, which is C, without changing the FC. This works, because C’s cost to 100::/64 via D is 4, much higher than it’s cost to 100::64 along C->A. Now consider what happens if A->100::/64 fails. If the timing of the query “works right,” C and B will be notified first, then finally D. Even if D is somehow notified before C, and D switches to C as its FS, the traffic is dropped, rather than looped—so all is happy.
Now change the situation a little. Assume the A->C link is cost Continue reading

The service provider is using a single platform from Nokia's Nuage to enable end-to-end automation between its WAN overlay service and its data center overlay service.
Take a Network Break! VMware announces its Virtual Cloud Network vision and outlines the product portfolio to bring that vision to life. Dell Technology World showcases new servers and storage and cements Dell’s one-stop-shop strategy. Cisco spends $270 million to buy relationship intelligence purveyor Accompany.
Cisco also shed its service provider video business, Anuta Networks makes its orchestration platform available as SaaS, and the Lojack laptop recovery software suffers a serious vulnerability.
Meanwhile, a Webex vulnerability enables remote code execution, Arista shares dip despite a strong quarter, and Juniper shares rise slightly despite a poor one.
