1.	Network Upgrade (6/02 - 9/02) 
Scope:
•	Replaced all Nortel core routers with Extreme routers.
•	Replaced all Nortel closet switches with Extreme switches.
•	Replaced 2 100mb connections to Evans with 2 load-sharing 1gb links. 
•	Reassigned new IPs to all systems in EECS.
•	Connected BID network from HMMB thru 4 1gb pipes.
Result:
•	Increased core capacity from 6gb to 128gb (20x).
•	Increased floor switches capacity from 1gb to 64gb (64x).
•	Increased floor switches uplinks from 1gb to 2gb (2x).
•	Multicast capability everywhere.
•	Port level manageability.
•	Total of 2440 hot ports out of a max capacity of 3500.
2.	AirBears in EECS (9/02 - 12/02) 
Scope:
•	AirBears service in Cory and Soda.
Result:
•	Available Cory 1st and 2nd floors, Soda 2nd and 3rd floors.
3.	SpamAssassin (9/02 - 12/02) 
Scope:
•	Deploy enterprise level spam control on departmental email
front-end. 
Result:
•	Two redundant front-end Sun E220 servers running SpamAssassin for EECS incoming email. Software generates additional headers based on pre-defined rulesets; sers can filter out spam using headers. 
4.	Old Sun File Servers Phase-out (9/02 - 12/02) 
Scope:
•	6 Sun file servers were to be retired due to lack of vendor hardware/software support. Migrate all customers over to new infrastructure. 
Result:
•	Migrated over 500GB of data over to new clustered NetApp file servers. Old systems powered off 12/30/02. 
5.	New IMAP Service (8/02 - on going) 
Scope:
•	Migration of EECS IMAP service to IMAP v4.
•	Enable delegated admin access.
•	Enable IMAP wireless email.
Result:
•	Deployed two redundant Sun servers for EECS LDAP services.
•	Deployed one Sun V880 with 4 cpus, 8GB RAM, 400GB RAID5 spool and secondary 200GB RAID5 backup. 
•	Currently testing delegated admin to enable server side per user filtering capability. 
•	Will be testing IMAP wireless email module in the future.
6.	EECS Intrusion and Detection System (8/02 - on going) 
Scope:
•	Deploy hardware to actively monitor and protect the EECS network from external attacks. 
•	Deploy EECS VPN service.
Result:
•	Identified and purchased a pair of NetScreen firewalls.
•	Netscreen boxes inserted successfully into production EECS border in transparent mode. 
•	Currently provides monitoring and advance notifications of potential malicious traffic. 
•	Will test and deploy advance level controls (active blocking) for selected subnets in the future. 
•	Will test enterprise level VPN services in the future.
7.	EECS Next Generation Wireless (802.11a) (1/03 - on going) 
Scope:
•	Replace existing 802.11b network, relieve congestion, increase scalability, integrate with existing wireless networks. 
Result:
•	Identified the vendor to provide transparent solution that will maintain existing 802.11b user base and investments, while concurrently deploy 802.11a pilot network. Test units are currently being set up in selected EECS areas. 
•	Will allow multiple wirelss setups to co-exist, allowing greater flexibility for research and production services, as well as the ability to provide different level of services for different user bases. 
8.	EECS Datewarehouse (7/02 - on going) 
Scope:
•	Consolidate and integrate various EECS HR and infrastructure databases/data archives via a single front-end, accessible by users in EECS with varying degree of granularity. This will be the first step in implementing an EECS Portal. 
Result:
•	Deployed one new Sun server to replace the two old EECS/CS web servers. 
•	Deployed new EECS roster database with automatic updates to EECS LDAP. 
•	Currently building network port and systems databases to allow systems dministrators to view and update status. 
•	Next generation roster database will be rebuilt starting 4/03 for increased functionality.
