By providing a way for tools to see multiple network access points simultaneously, aggregation of traffic helps to increase network visibility for monitoring, security, and acceleration tools. However, this benefit can quickly become problematic for IT and security professionals as bandwidth increases on the aggregate pipes.
Challenges resulting from aggregation include:
- Analytic tools’ input ports become over-subscribed
- Dropped packets create gaps in network visibility
- Dropped packets and link oversubscriptions forces professionals to reduce the number of access points they can see simultaneously
- Additional network intelligence tools are required for more visibility, resulting in additional CAPEX costs
- Maintenance of additional network intelligence tools increases OPEX costs
- Monitoring, security, and acceleration tools’ processing abilities are wasted as these tools analyze superfluous information
- Monitoring requirements cannot be met because of budget limitations
Removing superfluous packets with filtering at the point of access mitigates these issues.
VSS’ filtering does this and then some.
- Filtering is done, up to Layer 7, completely within our vNodes’ hardware. There is no introduced latency, as happens with software-based filtering solutions.
- Filters are overlapping and user-independent. Different tools and different IT and security groups can use any traffic access point without affecting other tools’ or other groups’ visibility.
