1999 Cabletron Systems Survival & Growth - Enterprise Presentation Why Policy based Routing is required 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 –even addresses go right Can scale for for more bits e.g. 2, 3, 4 for more firewalls TCP-ACK TCP-SYN xx-xx-xx-x1xx-xx-xx-x0

1999 Cabletron Systems Survival & Growth - Enterprise Presentation Component Parts of Accounting Cabletron Traffic Accountant (CTA) –Interrogating, Viewing and Storing Data Flow Accounting Server (FAS) –Data Collector SmartSwitch Router –Infrastructure
95
1999 Cabletron Systems Survival & Growth - Enterprise Presentation Cabletron Traffic Accountant The Cabletron Traffic Accountant, CTA, performs many tasks –Aggregation 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
96
1999 Cabletron Systems Survival & Growth - Enterprise Presentation Flow Accounting Server The Flow Accounting Server, FAS, provides several key features –Scalable The FAS can accept up to 8000 LFPS messages per second 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
97
1999 Cabletron Systems Survival & Growth - Enterprise Presentation SmartSwitch Router The SmartSwitch Router, SSR, is a required element of the Accounting model 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
