Cone tracing is a way to approximate the result of casting many rays into a scene with a distribution on a lobe. This is done by taking samples along a ray, but as the samples get further from the ray origin the sampled mip map level increases. Each circle is a sample along a ray; the size of the circles corresponds to the mip map sampling level
Global Illumination Using Voxel Cone Tracing – Andrew Pham

We only trace a single cone in the direction of the reflection using a supplied aperture for the indirect specular lighting. The aperture is a crucial input to the cone tracing function that will allow us to calibrate the amount of reflection and specular effect as an approximation of the roughness of the material.

High Resolution Sparse Voxel DAGs - Chalmers

The cone tracing is performed by taking steps along the cone axis, with a step length corresponding to the cone radius, and accumulating quadrilinearly filtered voxel data. The interpolation requires duplication of data to neighbouring voxels, which result in a memory consumption of nearly 1024 MB for a 5123sparse voxel octree with materials.

Compared to SVO in the context of voxel cone tracing (as opposed to ray casting, where SVO is a clear winner), 3D textures allow for easier filtering, direct lookups without evaluating the octree structure, and potentially better cache and memory bandwidth utilization (depending on cone size and scene density).
