Allow Symantec Management Agents to download packages from peer computers
|
Enables the peer-to-peer downloading functionality that allows the client computers to download packages from their peers.
Note that only the peer computers that are managed by the same Notification Server can download packages from each other.
|
TCP/UDP port
|
HTTP server listens to the TCP port. Peer discovery engine listens to the UDP port. The same port number is used for both.
|
HTTP request timeout
|
The period that the HTTP server should wait for the peer commands or file download requests from peer computers to arrive. If the request is not completed in a specified time, it is canceled with a timeout error.
Note that if the timeout period is short (5-10 seconds), the slower client computers may drop out of the DHT network.
|
Maximum upload bandwidth
|
The maximum upload speed that the uploading peer can share between downloading peers.
|
Maximum download bandwidth
|
The maximum download speed that the Symantec Management Agent can use when downloading a package from a peer computer.
Note that this value is independent from the general throttling value. For example, if you set the general throttling to 500 KB/s and peer-to-peer downloading throttling to 10 MB/s, the bandwidth is limited to 500 KB/s while downloading from Notification Server or Package Server outside the subnet, but the peer-to-peer downloading traffic inside the subnet has 10 MB/s bandwidth.
|
Maximum number of requests per core
|
The maximum number of simultaneous requests from the peer computers that the HTTP server can process.
Note that this setting is per CPU core. For example, if you enter 5 for this option, the computers with dual core processor will have a total limit of 10 requests.
|
Maximum number of connections
|
The maximum number of simultaneous connections that the HTTP server allows.
This option lets you limit the number of the client computers that can simultaneously connect to a peer.
|
Total log size
|
This option controls the total size of HTTP log files. The size of a single log file is 1 MB.
|
Peer announcement interval
|
A period after which Symantec Management Agent sends out a broadcast packet to its peers.
|
Unavailable peer timeout
|
A period after which a peer computer is considered as unavailable since it sends no broadcasts and does not answer to the requests.
|
Additional subnets to discover
|
Additional network segments for peer engine to discover.
Note that the peers try to connect directly to the added subnets. Add the subnets only if the communication between the network segments is expected. If you expect communication only between very specific set of subnets, create a dedicated Targeted Agent Settings policy with additional subnets and target it correspondingly.
|
Maximum number of peers per download attempt
|
The maximum number of peers from which the client computer tries to download the package.
Symantec suggests increasing this number if the computers often go offline.
|
Maximum download attempts per package
|
The maximum number of attempts to download a package using peer-to-peer downloading. Each attempt consists of selecting the specified number of peers and then attempting to download the package from each peer.
If all the attempts fail, the Package Delivery will download the package directly from the Package Server or Notification Server.
|
Period between download attempts
|
The interval of peer downloading attempts.
Note that the timeout period for peer downloading does not increase. When a client computer downloads a package from Notification Server or Package Server, the timeout period increases on each attempt.
|
File block download progress on peer
|
This option lets you configure how often a peer computer notifies its peers about the package download progress.
A peer computer downloads a file block by block. The size of each block is 2MB by default. The peer computer sends notifications about the package download progress after a specified period of time. If download of a file block is completed, other peers can start downloading it.
|
Don't use peer-to-peer downloading
|
In certain cases, you can disable using the peer-to-peer downloading.
For example, if the computers are outside of the internal network and use Cloud-enabled Management for communicating with Notification Server.
