Very Simple Virtual Circuit Protocol
Notes to the Writer
Goals
- Describe basic user procedure
- Begin to describe underlying architecture and components
- Talk about substrate concept
Sections
- xxx
Figures
- Application header format
- xxx
Links
Versions
- 0
- VCI in first word of UDP payload
- VCI is globally unique
- 1
- VCI can change during transit as part of pkt processing
User-space pkt
- Tunnel socket appears in UDP header
- VCI is first word of UDP payload
- Payload also has timestamp (for RTT and space-time diagram)
Substrate Concepts
- Line Card
- Parse, Lookup, Header Format
- Control
Slowpath Implementation
- Filters for local delivery
- User-space process
- Has VCI-MI Socket map; i.e., M : VCI --> MI Socket
- Forwards pkt to socket M(pkt.VCI)
- Artifacts
- Tunnel-aware sender and receiver
- Slice process
- spp-config-sp-vsvc-XXX.sh (slowpath) configuration scripts
- Monitoring
Fastpath Implementation
- Requires mods to Parse and Header Format
- Uses generic Lookup
- Additional artifacts
- spp-config-fp-vsvc-XXX.sh (fastpath) configuration scripts
- Monitoring
Interesting Example
- xxx
