xx-xx-xx-x 1 TCP-ACK xx-xx-xx-x 0 • TCP ACK goes through firewall to server • Server side switch must ensure TCP SYN goes back thru same firewall to preserve state context • Use the Least Significant Bit of IP address to determine: – odd addresses go left TCP-SYN – even addresses go right • Can scale for more bits e. g. 2, 3, 4 for more firewalls 1999 Cabletron Systems Survival & Growth - Enterprise TCP-ACK Presentation Why Policy based Routing is required

• The Cabletron Traffic Accountant, CTA, performs many tasks Presentation Cabletron Traffic Accountant • The CTA receives files from the FAS and looks at the SIP/DIP pairs as well as Source/Destination Ports to determine conversations • Many flows then get “aggregated” down to a single entry in the database – Integration • After the Aggregation is done, the information must be entered into the database • Costing and Directory matching is done at this time as well – Reports and Queries • There are over 30 different prepared reports and queries that can be run against the data 1999 Cabletron Systems Survival & Growth - Enterprise – Aggregation
• The Flow Accounting Server, FAS, provides several key features – Scalable Presentation Flow Accounting Server • The FAS organises the messages by source SSR and Flow ID – Fault Tolerant • The FAS can be Primary for one group of Smart Switch Routers and also be Secondary for another group of SSR’s • When an SSR must switch from a Primary to a Secondary FAS, the Flow ID is the unique identifier to keep track of the flow status 1999 Cabletron Systems Survival & Growth - Enterprise • The FAS can accept up to 8000 LFPS messages per second
• The SSR has a Lightweight Flow Accounting Protocol, LFAP, agent embedded in firmware – Part of firmware version 2. 0. 0. 0 and later – LFAP is a TCP orientated protocol that “pushes” flow information from the SSR to the FAS 1999 Cabletron Systems Survival & Growth - Enterprise • The Smart. Switch Router, SSR, is a required element of the Accounting model Presentation Smart. Switch Router
