Monitoring Service Nodes
Network traffic is continuing its steep growth curve driven by the sheer volume of
connected devices and the diversity of applications ranging from smart meters and automobiles to high-speed enterprise networks to massive global content delivery networks. Service Providers, large enterprises and government agencies are already embarking on network migrations to 100G technologies and beyond to meet this demand, however maintaining network visibility is a very different challenge at 100G line rates. IT professionals must adopt innovative new approaches to maintain critical visibility for their security, compliance and business intelligence functions.
100G Network Visibility Challenge
Network packet brokers perform two main functions, flexible packet access to optimize connectivity from TAPs to tools, and advanced packet processing to optimize visibility and scalability of security and monitoring tools. As networks migrate to 100G, the benefits of flexible packet access begin to break down as expanding port capacity for 100G aggregation, filtering and load balancing challenges budgets. Further, advanced processing performance limitations force stacking of multiple packet brokers which makes the entire approach cost prohibitive and impractical. Several leading switch/router vendors have introduced TAP aggregation solutions leveraging their merchant silicon switches, combined with management software, to enable flexible packet access for cost-effective network visibility. As an alternative, several software defined networking (SDN) vendors have introduced solutions that provide monitoring fabric management software to control 3rd party 'white box' switches to achieve cost-effective visibility. While both approaches solve the 100G access problem, advanced packet processing needs are left to either x86-based 'service nodes' or legacy packet brokers, neither of which can scale to N x 100G.
The Solution: Monitoring Service Nodes
NetQuest's OMX Optical Monitoring Exchange leverages state of the art Field
Programmable Gate Array (FPGA) technology to deliver high-density advanced packet
processing. You can now migrate to an innovative visibility fabric based on merchant
silicon switches for cost-effective access and the OMX for N x 100G advanced packet
processing. The compact modular design supports up to four 8 x 100G cards in a
single rack unit for up to 3.2Tbps of advanced processing.
Mass removal of VLAN tags, MPLS labels and IP Tunnels
OMX can remove multiple layers of IP tunnels including GTP, GRE, L2TP, etc in order to optimize analysis tools requiring IP packet access.
Combine the best of both worlds – merchant silicon switches for cost-effective access
and the OMX for your advanced packet processing needs to ensure your security and
monitoring tools have the visibility they need, while realizing significant CAPEX, rack
space, power and cooling savings.
