Cisco grabs Exablaze for low-latency chip technology

Cisco will continued to build up its internal-electronics tools with its planned purchase of   field-programmable gate array (FPGA) technology designer Exablaze for an undisclosed amount.Exablaze, founded in 2013, specializes in low-latency FPGAs used to construct logically reconfigurable digital circuits for networking gear in high-performance environments such as data centers, high-frequency trading (HFT), big-data analytics, high-performance computing and  telecommunications. Exablaze products include FPGA-based switches and network interface cards (NICs), as well as picosecond-resolution timing technology.To read this article in full, please click here

IDG Contributor Network: SD-WAN management means more than reviewing logs and parsing events

By creating a single view of all network data, you can do things better like correlating threat information to identify real attacks or keep a log of packet statistics to better diagnose intermittent networking problems.However, to turn data into value with the limitations of traditional systems, we must be creative with the solution. We must find ways to integrate the different repositories in various appliances. It’s not an easy task but an architectural shift that I’ve written about in the past, SASE (Secure Access Service Edge), should help significantly.SASE is a new enterprise networking technology category introduced by Gartner in 2019. It represents a change in how we connect our sites, users, and cloud resources.To read this article in full, please click here

HA inside Data Center

Overview

In Leaf/Spine VXLAN based data centers, everyone likes to provide HA with Active/Active in it, so choices are different. There are two types of HA in data centers, Layer 3 and Layer 2.

For layer 3 HA, always there is more than one spine that can provide ECMP and HA at same time. However, Layer 2 redundancy for hosts and l4-l7 services that connected to leafs are more than an easy choice. As Cisco provided vPC for nearly 10 years ago, almost this was the first (and only) choice of network engineers. Also, other vendors have their own technologies. For example, Arista provided Multi-chassis Link Aggregation (MLAG) for L2 HA in leafs. But, there is always a problem in implementation of them. One example in vPC is “peer-link” that is an important component in the vPC feature. However, it can be a tough one in most cases like Dynamic Layer-3 routing over vPC or Orphan members that may cause local traffic switching between vPC peers without using Fabric links.

To address the “peer-link” issue, there is a “fabric-peering” solution that uses Fabric links instead of “peer-link” and convert it to “virtual peer-link”. With this solution there is no concern Continue reading

The Week in Internet News: U.S. Lawmakers Threaten Anti-Encryption Regulations

Don’t make us make you: Members of a U.S. Senate committee recently told representatives of Facebook and Apple that they need to give police access to customers’ encrypted communications, or they will be forced to by Congress, the Washington Post reports. The companies told lawmakers that backdoors in encryption would be exploited by cybercriminals.

Facebook declines: Meanwhile, Facebook has refused a request from U.S. Attorney General William Barr to build encryption backdoors into WhatsApp and Messenger, the New York Times reports.

Women want to be included: As Internet access is growing in the central African country of Chad, women are demanding to be in on the action, Reuters reports. Women across sub-Saharan Africa are currently 15 percent less likely to own a mobile phone than men are and 41 percent less likely to use the mobile Internet, the story says.

Gigabit tech boom: Gigabit-speed Internet service is turning some small U.S. cities into tech centers, bringing businesses and jobs to the areas, Inc. says. The story looks at businesses taking advantage of gigabit-speed networks in Chattanooga, Tennessee, Melbourne, Florida, and Sarasota, Florida.

Arrested for reporting: Thirty journalists are currently in prison worldwide on charges related to Continue reading

Network Break 265: Cisco Chips At Broadcom With New ASIC; AWS Gives Networking Some Love

On today's Network Break we analyze Cisco's new ASIC platform and the 8000 router series, dig into a string of AWS announcements related to networking and security, and discuss new products from Cato Networks and Silver Peak.

The post Network Break 265: Cisco Chips At Broadcom With New ASIC; AWS Gives Networking Some Love appeared first on Packet Pushers.

BrandPost: Customers Demonstrate the Benefits of Secure SD-WAN Across Industries

Given today’s expanding networks, largely being driven by cloud transformation and similar digital transformation efforts, keeping everything connected in a single, easily manageable environment is a critical challenge. Extending things like cloud services to your mobile workers and branch offices will inevitably impact your network’s performance – especially if you are still trying to route traffic through your central network using things like WAN routers and MPLS connections in a hub and spoke design. Routing cloud-based applications through a WAN link to the central network can severely impact productivity and user experience while creating continually increasing bandwidth loads.To read this article in full, please click here

Figure Out What Problem You’re Trying to Solve

A long while ago I got into an hilarious Tweetfest (note to self: don’t… not that I would ever listen) starting with:

Which feature and which Cisco router for layer2 extension over internet 100Mbps with 1500 Bytes MTU

The knee-jerk reaction was obvious: OMG, not again. The ugly ghost of BRouters (or is it RBridges or WAN Extenders?) has awoken. The best reply in this category was definitely:

I cannot fathom the conversation where this was a legitimate design option. May the odds forever be in your favor.

A dozen “this is a dumpster fire” tweets later the problem was rephrased as:

7 considerations when buying network-automation tools

The concept of network automation has been around for as long as there have been networks, and until now the uptake has been slow for a number of reasons including resistance from network engineers.  But now forces are coming together to create a perfect storm of sorts, driving a need for network automation tools.One factor is that more and more network teams are starting to feel the pain of working in the fast-paced digital world where doing things the old way simply does not work.  The manual, box-by-box, method of configuring and updating routers and switches through a command-line interface (CLI) is too slow and error prone. [Get regularly scheduled insights by signing up for Network World newsletters.] Also, the rise of software-defined networks (SDN), including software-defined WANs (SD-WAN), has enabled network-automation tools to evolve from operationally focused point products that address things like change management and configuration into policy and orchestration tools.To read this article in full, please click here
