Phase 10 Plan 1: Classification Layer — Constants and Rules Summary

Added 21 new TrafficClass constants (IMAP, POP3, SMTP-sub, FTP, SMB, TFTP, RDP, Telnet, VNC, MySQL, PostgreSQL, Redis, MongoDB, mDNS, SSDP, SNMP, SIP, QUIC, LDAP, Kerberos, Syslog) and 30 new port-matching rules to the classify package, expanding traffic classification from 14 to 35 classes (32 in AllClasses(), 3 deferred to Phase 11).

Tasks Completed

Task	Name	Commit	Files
1	Add 21 new TrafficClass constants and update AllClasses()	50e0474	classify/types.go
2	Add 30 new port-matching rules to DefaultRules	cd8593e	classify/rules.go

What Was Done

Task 1 added 21 new TrafficClass constants to classify/types.go, grouped by protocol family with comments:

• Mail: ClassIMAP, ClassPOP3, ClassSMTPSub
• File Transfer: ClassFTP, ClassSMB, ClassTFTP
• Remote Access: ClassRDP, ClassTelnet, ClassVNC
• Database: ClassMySQL, ClassPostgreSQL, ClassRedis, ClassMongoDB
• Discovery: ClassMDNS, ClassSSDP, ClassSNMP
• VoIP: ClassSIP
• Web extension: ClassQUIC
• Infrastructure extension (Phase 11 deferred): ClassLDAP, ClassKerberos, ClassSyslog

AllClasses() updated to return 32 classes — the 14 existing classes plus 18 new ones. ClassLDAP, ClassKerberos, and ClassSyslog are intentionally excluded because their ClassFreqConfigs entries do not exist until Phase 11.

Task 2 expanded DefaultRules in classify/rules.go from 12 to 42 rules. All 30 new rules are specific-port rules placed before the catch-all entries. Key behaviors:

• Plain/TLS variants map to the same class (IMAP 143/993, POP3 110/995, LDAP 389/636, SIP 5060/5061 tcp+udp, FTP 20/21)
• QUIC uses Protocol: "udp", DstPort: 443 — distinct from HTTPS at tcp/443
• Catch-alls {tcp, 0, ClassOtherTCP} and {udp, 0, ClassOtherUDP} remain as the final two entries

Verification Results

• go build ./classify/... — clean compilation, no errors
• go test -count=1 ./... — all 7 packages pass (classify, synth, aggregate, capture, cmd, config, encode)
• TestAllClassesHaveConfig — PASS (32 AllClasses entries all have ClassFreqConfigs entries)
• TestClassFreqConfigsMatchAllClasses — PASS
• TestFrequenciesInRange — PASS
• TestGroupFieldPopulated — PASS

Final counts:

• Total TrafficClass constants: 35 (14 existing + 21 new)
• AllClasses() entries: 32 (14 existing + 18 new; LDAP/Kerberos/Syslog excluded)
• DefaultRules entries: 42 (12 existing + 30 new)

Deviations from Plan

None — plan executed exactly as written.

Known Stubs

None.

Self-Check: PASSED

• classify/types.go exists with 35 TrafficClass constants including ClassIMAP, ClassMongoDB, ClassQUIC, ClassSyslog
• classify/rules.go exists with 42 rules including DstPort 3306 ClassMySQL, DstPort 27017 ClassMongoDB
• AllClasses() returns 32 classes; does NOT include ClassLDAP, ClassKerberos, ClassSyslog
• Commits 50e0474 and cd8593e exist
• go test -count=1 ./... all green
