4.6.3Protocols Supported
TCP/UDP/IP - | Transport Control Protocol/User Datagram Protocol/Internet |
| Protocol, providing connectivity over LAN/WAN to any |
| networked computer. |
HTTP - | HyperText Transport Protocol, providing a |
| to the management computer. (‘Max. number of simultaneous |
| connections’ = unlimited, although only one is processed at a time) |
HTTPS - | Hypertext Transfer Protocol over Secure Socket Layer is a Web |
| protocol that encrypts and decrypts user page requests as well as |
| the pages that are returned by the Web server. It uses Secure |
| Socket Layer (SSL) as a sublayer under its regular HTTP |
| application layering. HTTPS uses port 443 instead of HTTP port |
| 80 in its interactions with the lower layer, TCP/IP. SSL uses a 40- |
| bit key size for the RC4 stream encryption algorithm, which is |
| considered an adequate degree of encryption for commercial |
| exchange. |
FTP - | File Transfer Protocol, providing access to the ‘FTP file system’ |
| of the TANDBERG Gateway. (‘Max. number of simultaneous |
| connections’ = 1) |
TELNET - | Provide a standard |
| functions. (‘Max. number of simultaneous connections’ = 8) |
TELNET CHALLENGE - An option to the standard Telnet service. Telnet Challenge offers a
| telnet connection where the password is not sent over the network, |
| hence impossible to sniff. |
SNMP9 - | Simple Network Management Protocol, standard for network |
| management and surveillance. (RFC1157 SNMPv1, RFC 1213 |
| |
DHCP - | Dynamic Host Configuration Protocol, enabling the system to |
| automatically be given IP address and Subnet Mask when |
| connected to a network with a DHCP server. |
In addition to the above, TCP/IP based protocols allowing management to be performed
