14 Branch Repeater Technology – HDX Broadcast (Improve inefficient protocols) (Reduce application turns and data) (Overcome loss/latency penalties) (Prioritize critical traffic) Adaptive TCP Flow Control Adaptive Compression Adaptive Protocol Acceleration Prioritization and QoS

15 Intelligently accelerates common application protocols Adaptive Protocol Acceleration Mitigates latency by reducing round trips (chatty protocols) CIFS (File Sharing) MAPI (Exchange) Makes compression engine application-aware Separates headers from payload ICA, CIFS, MAPI, HTTP, FTP, NFS Example: CIFS

16 CIFS CIFS: Common Internet File System Most common file sharing protocol Microsoft Office, Linux Open Office, etc. Windows XP/Vista, Windows Server 2003/2008, Mac OS X NetApp Filers, EMC File System Access Drag/Drop, Read/Write, Copy, Directory Browsing

17 Example: CIFS – without Branch Repeater I want to open a file \\dog\bone\blue “Whatever” John Whomever Which file? Who are you? Password? OK, It’s open! 250ms 1000 ms

18 Example: CIFS – with Branch Repeater I want to open a file \\dog\bone\blue “Whatever” John Whomever Which file? Who are you? Password? I want to open a file \\dog\bone\blue “Whatever” John Whomever Which file? Who are you? Password? OK, It’s open! 1 ms 125 ms 1 ms OK, It’s open! 125 ms 252 ms Open \\dog\bone\blue for John Whomever, password “Whatever”

19 Branch Repeater CIFS Performance

20 CIFS Acceleration Requirements Windows 2003/2008 Server : Set “Microsoft network client: Digitally sign communications (always)” to “Disabled” Set “Microsoft network server: Digitally sign communications (always)” to “Disabled” Windows 2000 Server : Set “Digitally sign server communication (always)” to “Disabled” Set “Digitally sign client communication (always)” to “Disabled” For Windows 2008 Server Disable SMB 2.0 See :

21 Faster sending/receiving of attachments Lessen MAPI-related bandwidth requirements Increase mail system responsiveness for branch office users Help enable Exchange server consolidation Drastically reduce idle time in sending/receiving s Iterations of same or similar messages by Optimization when different users, different applications access similar files Why accelerate MAPI?

22 What is MAPI Acceleration? MAPI Acceleration is: The pipelining of MAPI-based traffic between Microsoft Outlook and Exchange. Acceleration of the uploading and downloading of attachments made to messages. The compression of message attachments.

23 What is MAPI Acceleration? MAPI Acceleration is: The pipelining of MAPI-based traffic between Microsoft Outlook and Exchange. Acceleration of the uploading and downloading of attachments made to messages. The compression of message attachments.

24 How does MAPI Acceleration work? The Outlook client initiates a MAPI connection to Exchange on TCP port 135. User authentication and mailbox enumeration occurs. The Outlook client initiates a MAPI connection to Exchange on TCP port 135. User authentication and mailbox enumeration occurs. Branch Repeater detects the Outlook to Exchange handshake. If an accelerated connection is allowed the native Exchange compression is decompressed on the server- side Repeater. No acceleration = native compression only The Repeater/Branch Repeater pair then apply compression to subsequent MAPI traffic. Branch Repeater detects the Outlook to Exchange handshake. If an accelerated connection is allowed the native Exchange compression is decompressed on the server- side Repeater. No acceleration = native compression only The Repeater/Branch Repeater pair then apply compression to subsequent MAPI traffic.

25 How does MAPI Acceleration work? A compression bit is flipped in the packet prior to reaching the client, notifying Outlook not to decompress the native Exchange compression. Outlook then creates multiple connections the to Exchange server and message requests are exchanged simultaneously among the connections The downloading and uploading of message attachments (messages larger than 32k) is then accelerated. Appropriate compression is applied to obtain a higher compression ratio. Packet header : Memory-based history Packet payload: Disk -based history The downloading and uploading of message attachments (messages larger than 32k) is then accelerated. Appropriate compression is applied to obtain a higher compression ratio. Packet header : Memory-based history Packet payload: Disk -based history

26 How does MAPI Acceleration work?

27 Exchange (MAPI) Acceleration Requirements Microsoft Outlook/Exchange Server 2003 and Outlook must use normal Exchange mode (no HTTP or HTTPS proxy), without encryption To disable encryption manually on a single Outlook 2007 client, go to the menu shown uncheck the box, “Encrypt data between Microsoft Office Outlook and Microsoft Exchange’. To disable encryption for multiple users via group policies, follow the instructions at Change the Properties for “Enable RPC Encryption” to “Disabled” under “User Configuration: Administrative Templates: Microsoft Office Outlook 2007: Tools: Advanced Settings: Exchange.

75 Multiple Deployment Modes Inline Bypass NIC Virtual Inline PBR WCCPv2 SwitchRouter Repeater or Branch Repeater LAN WAN SwitchRouter Repeater or Branch Repeater LAN WAN Optional HA

76 Multiple Deployment Modes : Proxy Modes

77 The 4-port NIC is two logically-individual fail-to-wire pairs 4-port NICs are for the environments that are: dual homed, load balanced, and redundant the multiple WAN links have the same speed Supports HA Pair mode starting with release 5.0 can be deployed inline, WCCP, or policy based routing modes High Availability – 4-port NICs in Repeater

78 High-availability mode Transparently combines two Branch Repeaters with Windows Server into a primary/secondary pair Uses standard protocol VRRP Supports multiple HA deployment topologies for uninterrupted service to the branch High Availability Mode in Branch Repeater

79 Asymmetric Routing: In a multi-homed environment, a packet on a given connection might travel over either link Approaches to Resolve ‘Asymmetric Routing’ Group mode over non-redundant links with possible asymmetric routing

80 When multiple WAN links exist. Primary/secondary configurations. Load balanced configurations. Possibility of asymmetric routing issues. Group mode can be used on redundant links without reconfiguring routers. Group mode applies only to the appliances on one side of the WAN link. Appliances in group mode have no affect or reliance on the appliances on the other side of the WAN link. Why deploy in Group Mode Primary Link Backup Link

81 Within a Group Mode grouping, there is a connection “owner”. The owner of a connection is set by default according to a hash of IP/port pairs. The owner can optionally be set according to specific IP/port-based rules. Group mode uses a heartbeat mechanism to verify that other members of the group are active. Packets are only forwarded to active group members. How does Group Mode work? Primary Link Backup Link

82 If traffic arrives first at the “owning” appliance, it is accelerated and forwarded normally. If it arrives first at a non-owning appliance, it is forwarded to its owner, which accelerates it and returns it to the original appliance for forwarding. In addition, it means that an appliance is available for acceleration even if its link is down. When the routing tables change to bypass the failed link, group mode still forwards the packets through the owning appliance before sending them across the remaining link. How does Group Mode work? Owning Appliance
