The Source Port Labeling feature of the GigaSMART® engine provides context to packets and allows tools to properly assess network behavior and threats based on where they are happening in the network. When a packet arrives into the Gigamon Deep Observability Pipeline, it could have come from one of dozens or hundreds of network access points.
Before forwarding the packet to a monitoring or security tool, Source Port Labeling adds a trailer to the packet that identifies on which port the packet arrived. The tool can query the deep observability pipeline using the Rest API and look up the Cisco Discovery Protocol (CDP) or Link Layer Discovery Protocol (LLDP) information associated with the packet’s source port to know exactly where in the network problems or threats reside.
GigaSMART® offers several essential traffic intelligence services required for deep observability into infrastructure blind spots.
Delivers basic Layer 2–4 network traffic data to analysis tools.
Source Port Labeling
Provides context to packets and identifies behaviors and threats based on network location.
Adaptive Packet Filtering
Identifies patterns across any part of the network packet, including the packet payload.
Targets, identifies, and eliminates duplicate packets, blocking unnecessary duplication and sending optimized flows.
Truncates packets while preserving the protocol headers required for network analysis.
Advanced Load Balancing
Divides and distributes traffic among multiple tools based on a variety of data points.
Advanced Flow Slicing
Reduces bandwidth usage by slicing payloads and packets from long data flows.
Provides customizable data protection by overwriting specific packet fields with a set pattern.
Alleviates blindness of business-critical traffic at remote sites, virtualized data centers, or in the public or private cloud.
Provides a complete view of the applications running on your network.
Application Filtering Intelligence
Extends Layer 7 visibility to thousands of common and proprietary applications.
Application Metadata Intelligence
Provides application visibility to identify performance and quality issues, and potential security risks.
Enables mobile service providers to monitor subscriber data in GPRS Tunneling Protocol tunnels.
Forwards subscriber sessions to specific tools by filtering on subscriber, user device, RAN, or network slice IDs.
FlowVUE Flow Sampling
Provides subscriber IP-based flow sampling.
Enables enterprises and service providers to monitor VoIP traffic.
Creates a secure channel between the server and the end user's computer or other devices as they exchange information.
