  • Distinguish Between Ftp and Telnet Protocols

    1) Distinguish between the FTP and TELNET protocols. File Transfer Protocol (FTP) is used to transfer text files‚ programs‚ spreadsheets‚ and databases across the Internet. TELNET is a terminal emulation protocol used on TCP/IP-based networks. It allows users to run programs and review data from a remote terminal or computer. TELNET is an inherent part of the TCP/IP communications protocol. While both protocols deal with data transfer‚ FTP is useful for perusing a file of data as if the user were

  • Realistic Broadcast Protocol Handler

    "Realistic Broadcast Protocol Handler (RBPH) is a reliable multicast transport protocol mainly aimed for applications that require ordered‚ duplicate-free‚ multicast data delivery from multiple sources to multiple receivers. The advantage of RBPH over traditional multicast protocols is that it guarantees that a receiver in the group either receives all data packets from transmissions and retransmissions‚ or is able to detect unrecoverable data packet loss. RBPH is specifically intended as a workable

  • Ethernet and Spanning Tree Protocol

    following 3 questions as per assignment; QUESTION 1 – What are the three primary differences between Cisco layer 2 network resiliency and HP IRF resiliency? The first obvious difference is the protocols that they use. Cisco uses Spanning Tree Protocol (STP) while HP IRF uses the Link Aggregation Control Protocol. The second difference lies in the architecture being used. Cisco uses a mesh of network switches‚ linked to other switches in the aggregation layer‚ which in turn is linked to the core. This
