Editor's Notes
- Networking has barely evolved beyond CLI for managing systems. It seems like the innovations like Web 2.0 and System Simplifications never really made it to Network Management Systems of today.
- Answer to every problem has been to build a bigger networking system..
- Everything equates to a box – I can imagine Checkpoint Firewall and F5 Load Balancer as a box, but even Infoblox delivers a box for IPAM and DNS. It’s a symptom of our industry and not an issue of the technology. Its easier to sell a System.
- Physical Devices like Load Balancers, Firewalls, etcLimitations of VLANs and Policy Enforcement on the Physical Switching and Routing Infrastructure
- Managing L2 Networks is painful – for example, Multi-chassis LAG in order to avoid STP related link utilization issues CLOS network is nearly impossible to build and manage with traditional L2 approach
- VLANs cannot span L3 boundaries or need to pull L2 all the way to Core network
- With traditional VLAN based approach, there is a challenge with Overlapping Address space for tenants/applications
- Enabling VRFs require expensive Hardware in the Spine and/or Core layer
- CLOS Networks are becoming very common for full cross-section bandwidth across the entire clusterNo Layer-2 in the Underlay Netowrk
- Enterprise can avail compute and storage capacity on-demand from SP-IaaS and Virtual Private Cloud providers. Virtual Networks can be seamlessly orchestrated to enable secured segmentation of resources.SP L3VPN customers can extend their private enterprise network into IaaS networks seamlessly. Service Chaining can be instrumented to insert services like FW, Load-balancing, IPS or DDoS mitigation etc. in a horizontally scalable way.Fast provisioning and end to end automation can make business agile with lower response time.
