◦ turns off the power to your Ethernet jack when
there is no cable connected

Wake on LAN for wireless
◦ bring the well-known? wired Ethernet feature to
wireless networks.

Multi-Home Firewall Profiles

client’s behalf.
Windows XP & Windows Server 2003

NO AUTO TUNING
Severely limits round trip times
Sender transmits are limited to advertised receive window size
Window size backs off by 50% with packet loss
 Windows size increased slightly with every ACK

Manual tuning of receive window size does not offer ideal
results
Windows Vista/Win7 and Windows Server 2008 and R2
Auto-tune enabled by default
Max receive window determined by:
Application consumption capacity

Experience of being seamlessly connected to their corporate network any
time they have Internet access
Computer is joined to the network, Group policy applies.
Uses IPv6-over-IPv4 tunnel if no IPV6 connection available.
Sends only corporate traffic, web traffic stays local.
Authentication. DirectAccess authenticates the computer
Access Control. IT professionals can configure which intranet resources
different users can access using DirectAccess, granting DirectAccess users
unlimited access to the intranet or only allowing them to use specific
applications and access specific servers or subnets.

Optionally, install a
hosted cache in your
branch

Centralized cache of data downloaded by the
branch
◦ A centralized cache for
 Protocols: HTTP, SMB
 E2E encrypted/signed traffic: SSL, IPsec, SMB signing etc
◦ Does not “modify” protocols; benefits from protocol
optimizations
◦ Configurable size/location/persisted across reboots/flushable
◦ Works across multiple subnets
◦ Admins can seed content by writing custom scripts
◦ Can be a virtual workload in an appliance

Easy to deploy; clients are configured via policy
