Bridging network access points to monitoring, security, and acceleration tools can be a challenge when there are speed differentials. In mixed 10G and 1G network environments, speed mismatching causes monitoring, security, and acceleration tools to have problems with analytics.
- 1G analytic tools’ input ports become over-subscribed and drop packets when accessing 10G traffic
- 10G network intelligence tools become required for more visibility, resulting in additional CAPEX costs
- 1G network intelligence tools are rendered useless
- Monitoring requirements cannot be met because of budget limitations
Filtering will reduce traffic bandwidth, but never enough to allow for a 1G port to accept 10G traffic streams. The solution is VSS’ Session-based, Flow-aware Load Balancing. This feature, available on all Distributed, Protector, and Finder Series models, allows traffic from one access point to be balanced to up to 8 output ports using one of 10 balancing criteria options, e.g. source and / or destination MAC address, EtherType, IP address, TCP/UDP port, and GTP TEID. Packets from a unique session flow will be balanced to the same tool port.
Available on Advanced and Expert Edition models, Extended Load Balancing expands the 10 criteria to 22. Balanced flow options here include inner layer 3 and/or layer 4 headers, including GTP and MPLS encapsulated traffic. This removes the need to de-encapsulate the packets before load balancing. |
