Troubleshooting Wireless Networks

• How does software-defined access work?

  Service providers and enterprises use software-defined access to extend SDN beyond the data center and WAN to the edge of the network. Learn about its developments and benefits. Continue Reading

• NetOps, SecOps, DevOps concepts merge to automate security testing

  By adopting DevOps concepts, network teams can automate security testing. But, as development, network and security tasks mingle, some staffing challenges can arise. Continue Reading

• How do last-mile connections work for SD-WAN deployments?

  SD-WAN technology plays well with existing last-mile connections, and it allows enterprises to use more than one type of transport link. But beware of provider sprawl. Continue Reading

• load balancing

  Load balancing is a technique used to distribute workloads uniformly across servers or other compute resources to optimize network efficiency, reliability and capacity. Continue Reading

• optical network (photonic network)

  An optical (photonic) network transmits information as optical rather than electronic signals: It uses light, not electrical currents, to convey data. Continue Reading

• What is the status of VNF deployments among service providers?

  Although service providers are undertaking VNF deployments in the network core, they're hard-pressed to deploy them at the network edge due to complexity and cost.Continue Reading

• modulation

  Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal.Continue Reading

• Time-sensitive networking standards could boost industrial control

  With the help of VLAN priority levels, time-sensitive networking can make packet flow more predictable. The technology could especially benefit the factory floor.Continue Reading

• What effect does NetOps have on enterprise networking teams?

  Similar to the DevOps framework, a NetOps approach provides networking teams with a way to use automation and virtualization to create more agile networks and deploy applications faster.Continue Reading

• A 7-step checklist for designing a cloud migration plan

  Enterprises want their applications to be portable and able to shift easily among multiple cloud providers. To do that, putting together a good cloud migration plan is a must.Continue Reading

• Does software-defined networking architecture use segment routing?

  Segment routing steers packets using a list of instructions, and it can be used in MPLS and IPv6 architecture. But does software-defined networking architecture support it?Continue Reading

• Ethernet

  Ethernet is the traditional technology for connecting wired local area networks (LANs), enabling devices to communicate with each other via a protocol -- a set of rules or common network language.Continue Reading

• How do I begin network infrastructure planning for SD-WAN?

  When gearing up for SD-WAN upgrades, enterprises should take their time with network infrastructure planning. These three steps can help get them started.Continue Reading

• network analytics

  Network analytics is the application of big data principles and tools to the management and security of data networks.Continue Reading

• What is multi-access edge computing, and how has it evolved?

  Multi-access edge computing provides the processing capacity needed to support the increase of 'things' at the network edge. But for all its promise, MEC has challenges to face.Continue Reading
