Network As a Sensor for Application Assurance
Use Cases
Needs Support across various PINS – Wireless, UA, WAN/Internet edge, Core, DC, Security
Visibility, Capacity Planning, Reporting on LAN & WAN
Zoom in on “Where The Problem Is” for business applications – could be ANYWHERE!
E2E QoS & ACL (any Policy) enforcement – Drop “selectively”, Access Marking & Core/WAN Queuing
“Readiness Assessments” – Determine readiness for Application Deployment at planned scale
Use Application Information to Drive Network Data Analytics – e.g. CMX/ wireless scenarios
To support cloud apps breakouts to the Internet based on app-aware Routing policies
Wireless (WLC, AP), Converged Access | 2/3+ clients connect via wireless (per latest VNI stats); Need to classify/mark at the edge; 90%+ still deploying centralized WLCs; Prevent scavenger apps from getting too deep! Block/Mitigate heavy hitters over shared (half duplex), second most congested medium! |
Distribution, Core | Troubleshooting – analyze traffic utilization (packet captures) Domain based routing starting at L3 Distribution for cloud apps (ITeS use case) |
WAN Edge | Premium Links & Limited Bandwidth – Need Capacity Planning & Optimal allocation for apps |
Internet Edge | Cloud migration – Need for DIA and first packet classification for cloud apps |
Wired Access | 1/3 traffic still wired; 60-70% is voice/video with low latency requirements. Waiting till WAN is too late! Classification of this traffic known to be cumbersome today (port/subnet based) |
Data Center/Server Farm | Apps reside in DC – need to identify app level performance issues in multi-tiered client-server design |
Firewall, Perimeter Security | Entry Point (check what apps to allow) – Filter Applications/Users – URL filtering |
MSP Edge | Provide Application Level SLA – Managed Services |
Requirements for Future Application Identification:
We need an
Authoritative · Light–Weight · Unambiguous
way to identify applications.
We then need to be able to
link that Application Identity to Organizational Policy
for enforcement, accounting, etc.
How can we do this while addressing the challenges noted?
