The network of Fig. 5-37 uses RSVP with multicast trees for hosts 1 and 2 as shown. Suppose that host 3 requests a channel of bandwidth 2 MB/sec for a flow from host 1 and another channel of bandwidth 1 MB/sec for a flow from host 2. At the same time, host 4 requests a channel of bandwidth 2 MB/sec for a flow from host 1 and host 5 requests a channel of bandwidth 1 MB/sec for a flow from host 2. How much total bandwidth will be reserved for these requests at routers A, B, C, E, H, J, K, and L? A D G 1 Senders 3 B E Z 4 H K 2 Receivers (a) 5 с F L A 1 D. G. J 3 B 4 E H (b) 2 : 5 1 i D.

Question
The network depicted in Fig. 5-37 utilizes RSVP with multicast trees for hosts 1 and 2. The following details are provided: - Host 3 requests a channel of bandwidth 2 MB/sec for a flow from host 1. - Host 3 also requests another channel of bandwidth 1 MB/sec for a flow from host 2. - Simultaneously, host 4 requests a channel of bandwidth 2 MB/sec for a flow from host 1. - Host 5 requests a channel of bandwidth 1 MB/sec for a flow from host 2. The task is to calculate the total bandwidth reserved for these requests across the routers A, B, C, E, H, J, K, and L. ### Diagrams: #### (a) Full Network Topology: - Senders are denoted at the top (hosts 1 and 2). - Receivers are at the bottom (hosts 3, 4, and 5). - Routers are labeled as A, B, C, D, E, F, G, H, I, J, K, and L, forming a complex interconnection. #### (b) Multicast Tree for Host 1: - This tree starts from host 1. - The data passes through routers A, E, and branches through routers H and K to reach receivers 3, 4, and 5. #### (c) Multicast Tree for Host 2: - This tree begins from host 2. - Data traverses through routers C, E, and branches via routers H and K to reach receivers 3, 4, and 5. Each multicast tree represents the paths through the network that data from hosts 1 and 2 take to reach the respective receiving hosts. The tree structure highlights the links used for data transmission and helps calculate bandwidth allocation.
