16 HoPP Subscription Methods Several alternatives 1. Name advertisements by Content Proxy (CP) 2. Request named topic from CP receive specific name 3. Polling name inventory that contains meta info 4. Encode topic into name (e.g., part of prefix): /ρ/topic/unique_part Subscriptions are regular Interest requests 8 / 16
