A method of incorporating allocations of network access in a DOCSIS 1.0 compliant cable network, wherein users compete for bandwidth, includes limiting bandwidth consumed by a cable modem of a user to a value representative of that user's bandwidth allocation for a time interval. Preferably, the method includes the steps of: (a) generating cable modem configuration files, each of which limits bandwidth consumption by a cable modem of a user to a bandwidth allowance of that user equaling to the respective bandwidth allocation; (b) sending the configuration files to a Trivial File Transfer Protocol (TFTP) Server of the DOC Network; and (c) sending a command either to each user's cable modem, or to a cable modem termination system to which each user's cable modem is connected, to cause the cable modem to implement the respective new configuration file.

The present invention teaches methods and systems for blocking unauthorized access to cable modem configuration files stored on trivial file transfer protocol (TFTP) servers. Filenames are modified by the DHCP to incorporate an authentication key (and optional cloaking) prior to transmission to the cable modem. When the TFTP server receives a modified filename, it also generates an authentication key. The authentication keys must match in order for the cable modem to receive the configuration file requested. At a minimum, authentication keys depend upon the un-modified filename, the cable modem IP address and a “coordination pass phrase” known to the TFTP server and DHCP server, but not known to the cable modem. Variations include optional cloaking, various actions performed for non-matching authentication keys, selection of authentication key generating algorithm and inclusion of cable modem MAC address in the authentication key for all cable modems or for premium service customer cable modems.

Disclosed are methods and apparatus for handling FTP (file transfer protocol) control packets. In general terms, mechanisms are provided for facilitating FTP sessions between devices utilizing different protocols, such as IPv4 and IPv6. For example, FTP control packets from an IPv6 client to an IPv4 server are handled to facilitate such communication. Likewise, FTP control packets from an IPv4 client to an IPv6 server are handled to facilitate such communication. Communication is also facilitated when either or both of the client or server is in the form of a dual-stack device. To facilitate FTP session between devices having different protocols, FTP control packets between two different protocol devices are translated from one protocol to another protocol when required, e.g., from an IPv6 to an IPv4 format or visa versa.

A method and apparatus for routing a data request in a content delivery network receives a Hypertext Protocol (HTTP) format client data request and redirects the client data request to a file transfer protocol such that the data is transferred to the client in the file transfer protocol rather than HTTP. The redirection from HTTP, for example, to FTP or some other fileserver protocol outsources the load on the content engines while taking advantage of well-established methods of data handling and security. In addition, the network can dynamically be provisioned to handle a data load. In one embodiment, WCCP and HTTP redirection methods are used separately or in combination to provide a distributed file system in which client's requests benefit from content routing prior to interacting (via a file protocol) with a file server.

Each of the Internet video phones has information, including a company name, a language type, a version and an Internet Protocol (IP) address, and transmits information, including changed IP information, via an Internet when the IP information changes. The upgrade server performs an update using information transmitted from the Internet video phones and transmits upgrade commands to the Internet video phones when new firmware is distributed. The TFTP / HTTP server transmits the new firmware, which is requested by the Internet video phones in response to the upgrade commands, to the Internet video phones that requested the firmware.

Described herein are various principles for operating transfer protocols using adaptive flow control techniques. In accordance with some of these principles, a client may adaptively negotiate with a server regarding a window size to use when communicating datagrams using a connectionless content unit transfer protocol like the Trivial File Transfer Protocol (TFTP). In some implementations, a client may inform a server whether to increase or decrease a window size. In these implementations, the client may increase the window size upon determining that a previous window size has led to successful transfer of content without any loss of datagrams and the client may decrease the window size upon detecting a loss of a datagram. Because of the limited resources available in some environments in which these techniques may be used, in some implementations a window size may be increased by small amounts but may be decreased drastically upon detecting a loss.

A system, method, and computer program product for allowing a first processor to access flash or other non-volatile memory that is associated with a second processor. The first processor obtains parameters that allow the initialization of an internet protocol (IP) stack. The parameters can be obtained using the trivial file transfer protocol (TFTP), for example. The first processor communicates with the second processor using a socket protocol, sending a command word that represents either a read or write command. The command word specifies where in the non-volatile memory the access is to occur, and for how many bytes. Information is then returned to the first processor, allowing the first processor to verify the success of the access.

Classification and verification of static file transfer protocols is provided. A network node sitting in the path of packets classifies traffic according to its content, and then statistically verifies that the content actually matches the initial classification. Classification and verification are standard building blocks in networks systems that provide quality-of-service. However, unlike traditional quality-of-service building blocks, a system of the present invention takes a trust-but-verify approach, and thus can rely on longer-timescale statistical online or offline verification to reduce computational requirements. This improves scalability and reduces the cost and complexity that in part has prevented prior service differentiation systems from succeeding in the Internet. Internet Service Providers (ISPs) can combine the classification and verification building blocks with a networked directory service to allow further classification as to whether particular content is for pay.

The starting device comprises a running module and a downloading module. The baseboard management controller is used for executing the method. When the OS cannot be started through the local OS file, the first BMC downloads the OS file of the second BMC from the second BMC, and only one OS file can be stored on the memory of the first BMC.
